You can connect your dump load wires to a hot water heater heating element to heat water instead of sending it to a heating element that causes more hot air near the electronics & wastes energy. Thanks for sharing your setup & knowledge.
That's true, but as I said before in prior comments of the same subject, I live in the desert and don't need any more hot water. My tankless propane water heater only is used a couple of months a year, and very little at that. The heat produced in the battery room, is usually in the winter and helps keep my batteries warm through that time, making them more efficient.
@@GBear Gotcha but for someone wanting to go Solar & heat their hot water tank for free using the dump load & a different heating element in their hot water heater works quite well. Speaking of batteries have you done any vids on battery maintenance for lead acid types?
@miguelsalami Yes, before I actually moved out here, I had made a hot water barrel heater for my outdoor shower, but once I got here, I realized it was a waste of time. As for an actual video dedicated to battery maintenance, no I haven't. I have mentioned topping off with distilled water every couple of months, cleaning terminals, etc.
After 3 days of research, I finally came across your video. Really appreciate all the info you've supplied here and it's really great that you take the time to respond and help people in the comments. :) I'm busy 3D printing my first Airfoil vertical wind turbine. I'm looking to design an affordable system to keep a few items charged and operating during loadshedding (It's a South African thing). Not looking to make a profit, just want to help out where I can. Keep up the great work! :)
Like your information. Only thought that comes to mind. Mounting electrical terminals on to wood have risk. Since humidity, accidental roof leak or even a hard driving wind/rain storm, can get the wood wet. Not sure if you are in a desert, but I could never do this.
Welcome aboard. Yes, I am in a desert, and the battery room is weather proofed so rain won't get in. Also note that all wood mounted connections are low voltage. (12vdc) the 120/240v stuff is all in electrical boxes and conduits. Thanks for your concern, though.
You have an incredible handle on this subject and you are a wonderful teacher! Thank you for explaining all of your components in detail using language that we can all understand. Thank you!! ❤
Add on to my above comment ^^ If you ever have some extra time, would you be able to list or link some of the components that you used? So we can copy you!!
dumpload controllers with solid state relays SSR have a longer service life , well if the solenoid is switching on and off Alot because the turbine is in a good wind location the mechanical relays can get stuck on due to the result of endless arcing so many point out, Very Good video for beginners, one of the best ive seen.
Thanks for the input! Yes, there are better systems, but keeping a mechanical solenoid cool is key to longer life. If you have the money, go with the relay unit, though.
The dump load controllers with SSR you speak of are they the ones on the market that only use the AC 3 wires coming in then rectify & control the output to either battery or resistor/dump load? I am trying to take DC from a DC motor wind turbine (DIY) & divert it from the batts once full.
A 3 wire PMA needs a rectifier to convert its ac output to DC, DC can then go to the battery and a digital diverter will keep the battery from overcharge by diverting excess to a dump load resistance.
@@GBear The solenoid shouldn't need a fan. If it's getting hot, it means it's probably not a constant current solenoid, or it's exceeding the rated voltage/current.
Very nice set up. I spread my panels to separate charge controllers and batteries which each are dedicated to a specific task and load. Also I would dump excess load to a hot water heater inorder to storage the excess. Nice work sir.
Wow G Bear, Thanks so much. This clarifies both systems and answers a lot of questions. I feel more confident moving forward. It's so kind of you to put this together.
Thnx for showing your shelf system on the GH poles. 2morrow I will install a removable shelf (above the potatoes in grow bags) for seed starting. Later on I will relocate the potatoes, remove the shelf and grow tomatoes in grow bags and use the full height of the GH. Best wishes, greetings from Holland
I only intended to watch just to get a certain answer I was looking for. Not only did I get the answer to my question but I also learned a lot more about things I hadn't thought of. I watched every second and am so thankful that I did. Thank you for taking the time to make this!
Mr G Bear , first of all I appreciate you for enlightening us with this information. Is there a way to communicate, I have a few questions regarding this system. Thank you. @@GBear
the best video I've seen. The only thing i would say is that golf cart and fork lift batteries can be one battery ... like on your shelf. or packaged together as a larger 4000lb !! battery.. .. I'm getting windy.. .. great breakdown! well said..
Good Informative Video Sir. I have both in the works. 12V and 24V . The wind system being 24V. Most likely will be going with 24V only at some point. No Obstructions here so I can get away with the turbine only being 10Ft above my roof line. The main disadvantage of using a DC 2 wire Wind Turbines is DC voltage they produce requires heavier gauge wire and does not travel distances as well as AC or Three Wire systems can. They work for stuff like boats but for home use Best to just avoid the things. Well it's Semi Official. Wife works at Wally World and they was informed today to expect the shelves to start being short. The warehouses are feeling the pain. So if there was a Chines product your in need of at Walmart you might want to think about grabbing it.
Good stuff! I don't buy much from Wally World, although a subscriber just sent me a $10 gift if I order food online and pick it up. A lot of imports are affected by the Corona virus. Makes one think if it wasn't by design to quell chinese imports....🤔
@@GBear Got to agree, there is something very fishy regarding Chinese stock exchange and Trumps new tariffs. Here's to bringing back pharmaceutical mfg to the USA and all the other things we consume 👍
OMG ! Yes I REALLY like how you incorporated the solenoid into the path of the solar charge controller to the dump load. I was trying to find info to use PMA DC type wind turbines (I am making a small scale 12V 12A old water pump motor into a small vertical wind turbine to light a garden are at night :) Thanks again for posting all this GREAT info! ~C~
Connecting multiple charge controllers _without_ parallel capabilities will work, but it won't work very efficiently and you'll lose out on a lot of power, especially mixing MPPT and PWM controllers.
Welcome aboard! Yeah, I no longer use those controllers since I got my Midnite classic 150 and Renogy Rover controllers. Like day and night in efficiency!
I got a fan for that that plugs into the usb port on the controller, uses .1 watt, nice roller bearings, really quiet...the solenoid is like the one on a John Deere...if I ever get these tapered head Japanese screws out of this Honda PMA, I'll cobble one up, all I like is the solenoid...it's got magnets in it but I've got stouter ones, lol..yeah now that I've got 12 batteries I need a windmill...well too many irons in the fire but slowly slowly...when the sun got stronger a week ago the 10 I had would be full and now it's holding more...I have the forbidden bad ones you mentioned...for one reason I have to move them one day by myself as always and I dont have my old John Deere 790 with the front bucket anymore, just my butt...these are like 80 pounds each though...I can always get a fork truck battery later and have 1500 amp hours with the ones I have and it....I have to allow for the time to save up for such a big heavy thing ....but I can get by on what I have pretty well..I just have to do it between rain storms lol
Been trying to find out more on using more than one solar array and wind turbine system but every where I’ve gone seen to think they can talk the lingo and you’ll understand it. You have answered most of my questions in layman’s terms which I understand. Many thanks And great video look forward to more. And subscribed 👍🏼👍🏼
@@GBear great vids g-bear. My question is more about solar. I’m still stumped on how to divert solar power after batteries are charged. Like to heat water. Is there a simple diverter system that can be triggered by a timer or voltage that doesn’t involve using the batteries. One person mentioned it being necessary to have a switch or relay before the charge controller to prevent micro cycling batteries. Im still very new to all this. Thanks
Hi Spot On. Welcome aboard! Yes, there are ways to divert excess power to heating elements. Below is a link to one type, but the element included with this unit is for air warming. You would need to buy a water heater element in your voltage and subsitute it for the air heater element. I'm not promoting this particular charge controller, just showing you what is available. amzn.to/3yzDi8s You didn't mention the size, output, or even how much wind you get at your location, so I couldn't be specific on what you need or should expect from the setup.
@@GBear I appreciate the help, and thanks! it’s a small solar setup for a shed. I’m really just looking for direction on the concept tho. Interesting charge controller! i just want to make sure that the dump load doesn’t pull from the batteries and micro cycle them as some RUclipsrs mentioned some will. Do this “d” terminals carry the power right from the panels or will they pull from batteries? I haven’t seen charge controllers with a “d” symbol on them before
Thanks for the video, I have been trying to get info on how to size the wind generator. My off grid system has 3x100 amp lithium battery and 2.1 kw max solar... I need extra when no sun for days but I have plenty of wind.
Welcome aboard Ed! Ok, let me simplify the sizing for you. Since wind generators seldom put out their rated value for a consistent time due to fluctuations in the wind, get the highest rated one you can afford. You'll still need either a diverter or a good Midnite classic controller, the latter being the better choice. Not all controllers can be used for wind, but the Midnite classic is designed for it and is very efficient at it. Take into consideration when going with wind power, max output at what wind speed? Also, 3 bladed units are a better design than 5 or 7 blade units, but size and shape make a difference also. The tower or mast height and strength. My little KT5 PMA has pulled a 300+ pound concrete anchor out of the ground in 60+mph wind. Guy wires need to be steel rope able to handle 3000-5000 lbs of stress in high winds also. Then consider access to the PMA for maintenance. Simple things like bird poop can throw the balance off, causing excessive wear. That brings me to another thing...be sure to check your hub and blade balance before installing them on the PMA for best performance and output. Lastly, consider where the PMA will be located and the distance from the battery bank. Wire size and PMA vs PMG are affected by that distance.
Great video. Can you explain how your wind controller manages the power cover to control the power taken from the turbine at different RPM or Voltages. This is important for efficient operation of the wind turbine, especially at low wind speed. Thank you.
Way over my pay grade gBear. I think if I was to go off grid somewhere, and I'm not going to but if, I would just hire you and say build me one of those.
Thank you. I am heading off grid in three weeks and have much to learn. Moving into a home with an existing 1200 watt system, but it's ripe for a turbine.
Go BIG on turbine output, PMA, and be sure to have a solid, steady mast. Balance your blade setup prior to raising the mast for best output and performance.
You'll need to determine the treadmill motor output voltage and wattage, and whether your output is AC or DC. With AC you'll need a bridge rectifier that not only converts the AC to DC, but steps the voltage down to your usable battery bank level. You can't charge a 12v battery with 60 volts DC! With DC (PMG) you will also need a step down transformer, but not a bridge rectifier.
Thanks. Yeah it outputs DC. I'm looking into purchasing a 440 power charge controller is what I've read I should use. That with an inverter as the output. I plan on running dc stuff but then a maybe a couple smaller ac things.
Enjoyed the video. One thing (probably of many) that I haven't figured out yet is how is the voltage from the pma regulated. I assume the voltage will vary with wind speed but you need a nice steady 14.5v to charge the batteries.
Welcome aboard. Yes, the voltage is quite variable from a PMA due to wind speeds. The best way to control it is through a Midnite Classic controller after the bridge connector. I still have mine 'old school' style where the bridge rectifier connects to the battery bank and a dumpload controller monitors voltages in the bank and dumps it if it exceeps capacity. I was going to upgrade to a Midnite Classic controller bit the economy made finances go south.
Awesome, super informative video. Thank you VERY much for sharing. Would love to see a diagram of your system (including parts make and specs). Would also love to hear your thoughts on how to choose a good turbine.
I use a 100 amp 3 bridge rectifier. And a dump control board and solid state relay and 3 100 watt 3 ohm resisters in paralleled to drag mine down when the bank is full.
Got the same charge controller but my model is 2000 watts. 1000 watts for solar and 1000 watts for turbine. Whole system is 12 volts. The problem is I just bought my first solar panel which is 320 watts and it is pumping 30 volts. It is working fine when it is cloudy but in full sun the controller is shoving error and OVER PV is blinking. I found in the instruction that voltage from solar panel is higher than voltage set in controller. What can I do now? Did I buy wrong solar panel. I was trying to set higher voltage in the controller but the max is 17 volts. I do not understand what is wrong as this controller is made for 12volt 24 volt and 48volt systems. Anybody could help???
Welcome aboard Seb, sorry to hear about your troubles. If only you had contacted me sooner. I found out the hard way that those Chinese controllers are junk. I have since replaced mine with the Midnite Classic 150 and wish I would have just gone this way in the first place. You have a choice, keep that controller and get rid of the solar panel, and only use 12v, 100 watt panels connected in parallel with it, or keep the solar panel and buy a Midnite Classic 150, 200, or 250 for your solar controller and use the Chinese controller for a 12v turbine only. Note that the numbers for the Midnite Classic depict the maximum input voltage, so the 150 will accept 150vdc input, allowing you to connect your 320watt panels in series/parallel. Also the Midnite Classic group will control either wind or solar, but only one or the other, not both in the same controller. I hope this helps.
One small correction, the difference is between a PMA and PMG is NOT that PMA is AC and PMG is DC, they are both AC. The PMA is designed for a car originally and the PMG is designed to be a generator and is essentially better in every way.
Welcome aboard. Sorry, I have to correct you. A PMA has 3 wires all the same color, and no specific order of connection, all output, because it is AC (Alternating Current) until it runs through a bridge rectifier which is constructed of a series of diodes and converts that alternating current into direct current (DC) by redirecting multiple inputs to directional input/output. A PMG is a Direct Current "generator" That produces electricity through a 2 wire Direct Current, positive to negative, power with one red and one black conductor. Power out through positive and return through negative. The correction to your statement is: Both PMA & PMG are "alternators", the difference being, a PMG has a rectifier built in, an PMG requires one at the conversion location. This is why a PMA is preferred. An alternator, (requires smaller conductors) for longer distance of run, saving money on wiring, and conduit sizes. Thanks for your comment.
@@GBear I don’t kwow what to tell you. PMA is car alternator. It makes AC. The PMG is a 3 phase generator . It also makes AC. The one i have has 6 wires one sour I’d it. 6 wires coming out of it.
That's what I'm doing, your content is fascinating. I would love to have teachers like you lol. I have a question, I can always connect my wind turbine to a SOLAR CHARGE CONTROLLER? Aren't there charge controllers for wind turbines? If so, Is it possible to connect a wind turbine and some panels to the same charge controller?
@@marceloadrianmendodelacruz5451 yes, there are hybrid controllers that handle both wind and solar. I prefer not to use them from experience. I had to cycle through the controller to distinguish between which was producing what. By separating them out I am able to see those numbers at a glance.
Thanks for the info, that makes sense. I'm currently doing a project for my thesis that consist on perimeter lighting for my University parking lot with eolic and solar energy as power source. Your knowledge is gold for me, I appreciate the help! Greetings from Mexico.
@@marceloadrianmendodelacruz5451 in the near future I will be installing a solar powered submersible pump system in my water storage tank to keep the water in motion during the hot summer days. This should help prevent stagnation and algae growth. I just ordered the parts and should receive them in a couple of weeks.
Yes, it is a hybrid controller, but not a good one. Same with the one right beside it. I bought those in my early days of learning and retired them when I found better, more efficient options.
Smart man! We all have to start somewhere and sometimes learn the hard way. I try to share what I learned that hard way to help others save money, time and frustration. Welcome aboard!
GBear, another alternative to dumping your excess power, feed that extra power into a secondary 14 volt battery bank by using a combination of 6v & 8v golf cart batteries, which requires more current for charging. I’ve been using BatteryMINDers 2012’s for all five battery banks except one AGM bank that uses the BatteryMINDer 2012-AGM model. My golf cart batteries and AGM’s are between 10-15 years old and only need to add acid once a year. I use two banks for Ham radio that requires 13.8 volts. BTW, a PWG also works as a pulse/desulf charger but I like that BLS-12N and I will see if I can buy a couple of those.
Umm you should never shunt of dump into anything that could run out of capacity. You could kill the turbine or your batteries or both or all three: catch things on fire. (10:20 looks a little fire risky to me)
No. It will turn on when the battery bank is over full, but the AIMS and the Midnite Classic also prevent overcharge, so the dump load never activates any more.
@@GBear GBear, thank you for the reply… it seems your video didn´t just enlighten me, but also a huge pouch of people! AIMS and the Midnite Classic will prevent overcharge and the dump load will not be used right? The thing is that I do want to use that extra power but not on that huge resistor, I want to use it on a large water heater and/or another battery bank for gest house. The other thing I´m worried (as I´m using lithium-ion battery) is the micro cycling happening on the battery bank while using the dump load. Can you please give me some insights on these 2 issues?
curious will it not damage the battery if you feed the output of the rectifier direclty to the battery ? . Again I am not expert on this just asking to expand my knowledge. do you still need a voltage regulator to match the proper charging voltage of the battery ? feed the output of the rectifier to a voltage regulator or PWM or charge controller ? thanks
Welcome aboard! First, let's start with the basics. You should not attempt to charge, let's say, a 12v battery bank with a 24v turbine. Think of it like you car. You wouldn't replace the alternator with one that outputs higher voltage, right. Now, yes, you 'could' do it using a specific charge controller, a transformer, etc., but it would complicate your system and life, while costing you more. As far as connecting the bridge rectifier straight to the batteries, yes it will damage the batteries unless you also add a 'dump load diverter' to handle overcharges. You could also use a Midnite Classic charge controller set up for wind power conversion, which is the best option, as this allows you to fine tune and adjust the input for best efficiency.
Welcome aboard. I'm not sure what you are referring to, but if it is my PMA, it will generate max watts at maximum wind speed, for as long as the wind maintains that speed.
Too bad you are on the other side of the country, I'd love to help you with the setup, but from here, I worry about your safety while Jerry-rigging power. Where do you set up your panels? The Gustapo will spot them and throw you in the cooler.🫡😆
So what are you using for an inverter? You would need separate ones for 12v or 24v. Also the wattage and pure sine or modified sine wave makes a difference.
@@GBearihave 1500watt pure sign wave for the office i have 1000 pure sign wave for the freezers i have a3000 pure sign wave they are relibles for 24v i have a 25000 i have high dollar charge controllers tristar but don,t whant to mess them up they all have dip switches for setting
Good vid & explanation of ur system G Bear. Wouldn’t it makes sense to use ur dump load to make hot water or at least a pre-heater for a hot water system, but use ur excess solar power from ur controllers as well, as soon as ur batteries are full SOC have the controller divert any extra power to ur hot water system. I have a 50ltr hot water system that operates this way on a stationary 40’ bus, a 24v system, 3kw AIO inverter, 2.5kw pv panels & 10 kwh lifepo4. I can run microwave, 2.5kw split air con, H/W system, everything off Solar & heat water for the family of 4 showers daily while fully charging batteries. I have a 24vdc multi power element (300w, 600w, 900w capable) for the H/W system but never fitted it as I use the inverter with a AC voltage/dimmer control so I can adjust the output to the 240vac 1800w element I installed previously, instead of the 3600w element it had standard. I can use the controller to vary the power usage of the H/w system if its cloudy or for other reasons. For my house I have a 5kw AIO 48v system with 10 kwh of pv (grid tied) & 30 kwh of lifepo4, I only use about 20%-25% battery SOC a night on either system generally, higher voltage systems are much more efficient if ur going to use an inverter, & use a step down (or up) converter for lights & light loads to save on wasted inverter idle power usage. Lifepo4 batteries are a game changer now days in so many ways & using a decent shunt ,means you can know very accurately how much power is going in, out & still available. They were PWM controllers u were trying to think of , it stands for ‘Pulse Width Modulation’, but Im sure u know that. Cheers
Welcome aboard. I live in the hot desert, and don't use much hot water at all. I use a propane, tankless water heater that gives me on demand hot water when needed. It is off 10 5 months of the year. My tote-cuzzi outside doesn't have a heater either, and the water is at 90°F or better.
G. Bear, I have a three-wire wind generator, and common inexpensive potted wind controller that came with it. All three wires from the generator are the same color: Red. And the three controller wires are all the same color, also. Does it matter which generator wire goes to which controller terminal/wire?, or can the hookup be made in any fashion, and still have the same, best result? The face of the controller has a diagram of a three-bladed wind turbine blade, with the center wire of the three controller wires coming from the second (middle one) of the three generator wires. If the order of the hookup matters at all, how can I determine which generator wire is that center wire? Or, as I speculate, since all the wires and terminals have the same color, does the order of the hookup to the controller (rectifier) simply not matter at all? In any case, how did YOU proceed, and manage to get a good result in the hookup? Please help! Others here may have this question, too. Thanks!, --Joe / Tucson ARIZONA
@W7DXW Welcome aboard, Joe! A 3 wire turbine is a Permanent Magnet ALTERNATOR, (PMA), and the order of the wires is not a factor in connections. Those 3 wires connect in any order to the controller you received with it, to the 3 same colored wires on the controller. That leaves a black and red wire to go to the batteries. You may want to order the following meter so you can monitor the power. amzn.to/3zZ6F8n
Thank you! for your help, you've done me a great, good turn (and others here, too, I think, who may have had the same quandary and puzzlement that I had, as newcomers to wind power). I was trying to figure-out the connection scheme for days, and was frankly going a bit stir-crazy, with various mental topological twists and turns, trying to figure out if all the connection schemes are (or should be) in fact equivalent. I even resorted to experiment, and tried different permutations of the connections, while spinning the turbine generator with an electric drill, and always got the same voltage output no matter HOW I connected the wires. I couldn't believe my eyes. You've very kindly settled it for me, now. T-H-A-N-K Y-O-U ! ! --Joe / Tucson
@W7DXW You’re welcome. Yes, it can be confusing to newcomers. The good thing is your test shows it is working properly, having the same voltage output on each combination. The charge controller they provide is basically a bridge rectifier which changes AC to DC through diodes. That's why I recommended the meter. Without a readout screen, you would never know if the power to the batteries was too high, especially with LiFePO4's.
How close to the ground can you have the turbines and have them still work OK? I want to be able to put one up but not have it so high up that everyone sees it, because our municipality I don't know if I can get away with it yet. So I wanted to find out what th eminimum height to get these to work typically is? And because maintenance would be easier if they aren't really high up. Thanks.
Welcome aboard, Noah! If you live inside city limits, they usually aren't allowed. They need to be high up, especially around multiple buildings that would affect air flow. Also, if you are on grid, it wouldn't do you much good anyway, unless it was a very large turbine. Sorry to sound negative, but I don't want to mislead you.
@@GBear Hey GBear thank you for the reply. I appreciate the comments. You weren't negative but just being real. Actually you are probably right. I'm curious if they could be used for camping though, or if it would just end up being too hard for a portable set up with one?
@Noah Riding The higher up you put them, the better they work. Solar is a much better bet for camping, as you don't always have wind, but the sun is pretty reliable. Turbines are supplemental providers, and shouldn't be relied on as the main source of power. After all, who wants to camp in 40mph winds?🤔
Thanks G bear!! great explanation, I’m trying similar project too, POC is done and now will need to design a battery bank. 1) how do you wire the batteries together with 2 source of charging ? I’m thinking to add another source for charging but not sure how to wire it. 2) If it’s a separated batteries zoning , how do we ensure the batteries are equally charge? 3) how do you connect all the batteries to the inverter? Do you have a battery bank management system in place? 4) how to detect a faulty battery under the batteries bank?
The reason automotive/car batteries don’t work well is because they use crank amps. Electric vehicle batteries don’t need that initial inrush of amps to crank anything.
Exactly. Car batteries are designed to give a quick burst of power, then recharge slowly, where electric vehicle deep cycle are designed to release power slowly and recharge quickly. 24v aircraft batteries work well for solar, but are very expensive.
Hi. I am Graham. How do you connect 2 or more charge controllers to the battery bank. Do you do it in parallel to the same battery bank or you split the battery banks so that each controller charges its on Bank. I have tried putting them in parallel to the same battery bank but one of the controllers always get damaged. Please help.
Hi Graham, welcome aboard. They need to be connected to the bank at different locations, and should be set with the same parameters. Also, only one should have the 'equalization' feature turned on. Connect the first one, positive to positive of the first battery, negative to the negative of last battery. Connect the other, positive to last battery, negative to first battery.
Great stuff, thank you! so basically the power from wind is going straight into the batteries ( disregarding the rectifier) not using something like a charge controller like the solar does, correct? Would this same setup translate to hydroelectric, no? (Pelton wheel being spun by water) lastly, where did you get that display showing power and voltage? Or what did you Google for?
Welcome aboard! Yes, 3 phase AC power comes in from the PMA (turbine) goes through a bridge rectifier to make it Single phase DC, then through the "high precision wattmeter", then through a breaker to the batteries. Then a dump load unit or digital load diverter is applied to the battery bank to prevent over charge.
You should mention with the solar wire the gauge could be less if the panels are wired in a series vs wired in parallel (more amps require thicker wire vs more volts and less amps and letting the mppt controller convert the higher volts to amps at the controller)
Well said 🙏👏👏👏 a lot of people make this mistake to parallel panels and they spend a lot of money in the cable but the problem is a lot of people use low amps charger(most of the cases cheap ones) and those they can't take higher voltage input like the midle/premium brands(even though there are quite a few cheap Chinese chargers that can take over 100v input and output 12-24V or more)
just noticed that your wall fan will blow air in the cabin not out... change sides and then it will blow out ;) and your inverter will take air in true front and blow out from back
I don't know what you are looking at, but the fan on the wall near the door blows out. The inverter fan blows towards it and it moves the air out through the vent. The fan on the other side feeds air into the inlet side of the inverter.
@@GBear your bridge rectifier fan blows towards rectifier... wall and inverter fans are blowing same directions... fan sticker is always where air comes out from it ;)
@@GBear I'm a 30 year retired electrician, I always said when I retire I don't want to have a electric bill , well I still do. But I'm looking into going wind and solar. but I'm doing my research first. Just because I'm a electrician I wired restaurants and solar is different. But for the DIY I have a little head start I do understand voltage drop and how to size wire. and a parallel V/S series. The Higher your voltage the lower your amperage. How long do you get out a a inverter.
Welcome aboard Tony! As with all electrical components there are variables as to how long they last. My first inverter was Chinese made and although it still works I found out the hard way that it's "pure sine wave" wasn't clean. It caused problems with my refrigerator and stove and microwave. It also lied about its capacity claiming 32000 watt surge capability, the in fine print right on the inverter it says it won't handle a pump motor 1200 watt surge. Long story short, avoid Chinese made inverters. I have since switched to an AIMS split phase low frequency inverter and am loving it. With proper care, not to overload it, keep it clean and dust free, I expect a long lasting relationship with this inverter.
@@GBear I love my portable wind and solar setup. I can tow it with my camper and use it to power my house at home. It took me 400 hours to weld drill and bolt cut and wire everything on it.
@@GBear yes i have made several because I am always finding something else to upgrade or do differently and even better than the first go. I am never finished with it.i am always adding something.
You should blow air in from outside, not suck 'hot air' out heat rises. Your extraction fan is too low and will actually bring the hot air from the ceiling down past your inverter
Question. I'm looking at the KT5 on their website, they say in high wind gusts it can produce up to 68V peak on the 12V model. It looks like their rectifier is rated to 1600V, but what would happen to the batteries? would it just trip the load dump solenoid?
Yes, but solenoid dump load systems are no longer used. Digital diversion units are the new wave. I live in a high wind area, but have yet to see more than 60amps and 880watts, and that was with 45mph winds. That's 14.6v. I was told the same thing as you, but can't figure out what they are talking about. A 12v PMA is a car alternator, and it would never put out more than 14.7 volts, even if you were driving 120mph with 5k rpm on the engine. I think they hype the product to sell more product. I bought their meter unit to monitor output and it failed in a short time. They gave me all kinds of crap about how it was my fault, etc., then it mysteriously got lost in the mail and I was out the money and the meter. I bought a Chinese meter and it has been working fine ever since.
If you have some strong young and very good friends an earth bag structure might be an option. Maybe one for the batteries and one for the other equipment. The equipment room could heat the battery room. Eg4 now has a self heated battery, I think it is 13kw and is about $4000. Maybe a suggestion for someone starting out that could be expanded on. Maybe a subject for your new paid channel. We could see some deflation in batteries after we get through inflation going down. Again thanks for sharing.
Not anything I have tried but just something I thought about. If you can get the right thickness of wall you might get it warm enough for the winter and then cool enough for the summer. Maybe do earth bag work shops. Get people to pay you to work for you. 😂
This all seems so complicated, and depressingly difficult. Do they make/sell ready-to-go systems, for people of low-tech understanding? Do I really need a shed full of wires and gizmos to get a wind turbine working? I'm looking for a simple setup where the wires from the wind turbine plug into one "box", then the output from that "box" is a cable that I can plug into my portable battery/generator to charge it. This is how it works with my solar panels.
Welcome aboard. Yes, times have changed. You can use a Midnite Classic charge controller after the bridge rectifier. Then just connect the Midnite Classic to your battery bank like you would with solar.
the green mppt has turbine input and dump terminals. have you considered buying another one for the turbine? or is the turbine greater than 600 watts. that green mppt is also available in 1000 watt model too. then you could get rid of the black pwm and its solenoid and use the all in one green controller to open and close the dump load.. also what about getting the 12v water heater element for your water heater tank to further alleviate grid consumption? heck its free energy. might as well right u definitely know what you are doing but you dont get any gold stars for organized wiring lol haha. good video tho. very helpful. thanks
Welcome aboard! My turbine is 1685watts. Those hybrid controllers are junk. I learned the hard way on that. I have since upgraded to a Midnite Classic controller for solar, and still use the dumpload as backup. But it never activates anymore because the Classic monitors the battery bank. I also have a tankless water heater so I don't need the preheated setup. You are in the early videos still, and you will see alot of advancements in later episodes of my playlist. Yeah, the wiring isn't pretty, but it works perfectly, lol. Thanks for your thoughts though.
@@GBear thanks , i will continue to watch. with the classic, when it shuts off charging to the bank, and you are rarely using the back up, how are you preventing over-speed without keeping some sort of resistance on the turbine?
@toobglued the turbine is connected directly to the battery bank. In the future I will be controlling it through its own Classic, which will make it more efficient.
what is the point of having a PWM module connected to the batteries to dump extra power if the power reaching to the batteries from the rectifier are already charging your batteries, won't they get damage over time more quickly provided there is no controller before power reached them after they peek in power? it seems to me that the PWM controller should go after the rectifier to charge your batteries and not later, not a criticism, i'm wanting to build a water wheel generator with either a PMA or PMG and its a bit confusing with all sort of information in the internet on how to connect stuff
Since a PMA or PMG can put out excessively high watts and amps at times, running it through a controller requires a special controller to handle those ranges. I have seen my PMA put out 166 amps, and actually fry the rectifier which was rated at 150A. The PMA is specially designed to operate a 'dump load' system, which puts a 300w load on the battery bank when excess power is created.
how did u ground your wind turbine? where did u attach the ground wire? my wind turbine is 20 feet up its on water well poles. how would i go about grounding it?
Drive a 6 foot ground rod into the ground if you don't already have one nearby, then attach the metal tower to that ground rod with at least #6 solid copper wire. The PMA or PMG is already in contact with the metal tower so no wire is needed at that connection.
Hey FRIEND! Touching base with you! Interested in learning how much power it generates. It 12volts you say. 1685 watt??? Got to have 90 mile/hr wind…that is rare!
Needs 90mph wind to produce 1685w. It starts producing at 9mph, but only about 30-40w. Normal winds here will reach 22mph and I can get a few hundred watts out of that. I have seen over 1000w in a wind storm with gusts of 45mph.
Welcome aboard! Just to charge them? Ok, I can see you are new to this, so let me help you understand more about solar. To charge a battery bank of any size, any size solar panel will supply a charge. To keep them charged as they may need more input. For a more accurate answer, more information is needed. 1. What will you be powering with your battery bank? 2. Are your batteries Lead acid, LifPo4, AGM, etc.? 3. Deep Cycle or Standard cycle? 525Ah only means you can supply 525 amps for 1 hour at 12 volts. Or , actually 1/2 of that. Because you only want to discharge a maximum of 50% of battery capacity. That gives you 3150 watts for one hour. (Amps times volts = watts) but remember, you will lose some of that just powering an inverter 12v to 120v. Heating and cooling appliances use a lot of watts, LED lights use very little watts. You need to total all the watts needed by your load, before you can determine how many batteries you need, and how many solar watts input you need, then what size charge controller and what size inverter you will require, keeping in mind that once the sun is gone at night, the battery bank will have the sole job of powering all your electrical needs without any help.
@G Bear's Off Grid Ways-A Homestead In The Desert Hi, I am completely new for this knowledge. My main use for washing machine 240v 2500w with hot washing and I have 5 AGM battery's 12v 105Ah each and 3000w inverter. Thanks
Ok, your battery bank is too small to run that washer after dark, and to run it during a sunny day you should have a solar array of at least the size of your load plus 20%. That will allow charging of the battery bank while powering the load. The washer will use 10.5 amps during standard run. Heating water will be a large draw. Using 220v, I assume you are in Europe? Your better choice would be 6 batteries connected series parallel for 24v, but then you would need to change your inverter to a 24v unit. Anyway, using 2000w of solar panels may allow you to operate the washer at peak sunny days. Connecting the panels in series parallel to increase the voltage will help also, but be certain not to exceed the charge controller's maximum voltage limits. You could possibly get by with four 305w solar panels, with 2 strings (connecting 2 panels in series, times 2) into a Midnite Classic 150 controller or equivalent since it will handle 12 or 24v input up to 150v. Just remember, always connect the batteries to the controller FIRST, then connect the solar panels, but dont do it while the sun is on the panels. Cover them.
As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load watts to find run time hours. Finally, multiply run time hours by 95% to account for inverter losses.
You'll have to google that question for your area. Yes, they sell recycled or refurbished batteries. They are lead acid batteries, very heavy, but very strong.
You don't mention that another advantage of the AC is that the current in the wiring is smaller so you have less line loss and can use smaller Guage wiring.
Do you ever have an issue with your PMA when you connect your battery bank PMA start swinging slowly and as soon as you disconnect the battery bank your PMA turns faster?
You should never connect or disconnect a PMA under load. The blades should be tied so they don't spin, then released after connections are made. The PMA connects to the bridge rectifier on the 3 pole side with wires in any order, but the output side of the rectifier with 2 poles are marked + or - and polarity is important when connecting to the battery bank. So, answer is no. I don't make or break connections while the PMA is spinning, so I won't see what you described.
@@GBear I made this video to explain the type of problem I am going through please let me know the solution if you ever had this issue Thanks ruclips.net/video/KMIY_xOg9R0/видео.html
I hooked up my turbine to my 24v solar system I already have set up. During the day, I can tell there is resistance to the turbine. At night, the turbine just free spins. Do you know what the problem is?
@@GBear I could be wrong but something tells me that his turbine isn’t made for a 24 volt system. I bet I could figure out the issue in a few minutes with my multimeter. Rule of thumb for me when it comes to DC power and battery banks: Never trust your eyes and the color of wires, only trust your volt meter, volt meter never lies!
Welcome aboard. First, you didn't say if your turbine is 3 wire PMA, or 2 wire PMG. You also didn't mention if your turbine has a controller, or not, and you didn't say if you also had solar coming in. If you plan to use the turbine, you MUST configure your battery bank to 24v, use a 24v controller if you also have solar, and a 24v inverter. The solar controller gets connected to the 24v battery bank FIRST, then connect the solar panels. If you are not using a charge controller for your AC turbine, you will need a 24v bridge rectifier between the incoming 3 wires of the turbine and the battery bank. If your 24v turbine is DC (2 wire, red and black) it can connect directly to the battery bank of 24v, but a dump load diverter will also be necessary.
this is the most old guy set up every. Nothing fancy and kinda made from rando parts. Love it.
Welcome aboard! Yeah, we all need to start someplace in learning about solar and what it will do.
You can connect your dump load wires to a hot water heater heating element to heat water instead of sending it to a heating element that causes more hot air near the electronics & wastes energy. Thanks for sharing your setup & knowledge.
That's true, but as I said before in prior comments of the same subject, I live in the desert and don't need any more hot water. My tankless propane water heater only is used a couple of months a year, and very little at that. The heat produced in the battery room, is usually in the winter and helps keep my batteries warm through that time, making them more efficient.
@@GBear Gotcha but for someone wanting to go Solar & heat their hot water tank for free using the dump load & a different heating element in their hot water heater works quite well. Speaking of batteries have you done any vids on battery maintenance for lead acid types?
@miguelsalami Yes, before I actually moved out here, I had made a hot water barrel heater for my outdoor shower, but once I got here, I realized it was a waste of time. As for an actual video dedicated to battery maintenance, no I haven't. I have mentioned topping off with distilled water every couple of months, cleaning terminals, etc.
After 3 days of research, I finally came across your video. Really appreciate all the info you've supplied here and it's really great that you take the time to respond and help people in the comments. :) I'm busy 3D printing my first Airfoil vertical wind turbine.

Welcome aboard! Thanks!
Like your information. Only thought that comes to mind. Mounting electrical terminals on to wood have risk. Since humidity, accidental roof leak or even a hard driving wind/rain storm, can get the wood wet. Not sure if you are in a desert, but I could never do this.
Welcome aboard. Yes, I am in a desert, and the battery room is weather proofed so rain won't get in. Also note that all wood mounted connections are low voltage. (12vdc) the 120/240v stuff is all in electrical boxes and conduits. Thanks for your concern, though.
You have an incredible handle on this subject and you are a wonderful teacher! Thank you for explaining all of your components in detail using language that we can all understand.
Thank you!! ❤
Add on to my above comment ^^ If you ever have some extra time, would you be able to list or link some of the components that you used? So we can copy you!!
You're welcome and welcome aboard!
Will do. I already have videos showing my favorite components, but will do another
dumpload controllers with solid state relays SSR have a longer service life , well if the solenoid is switching on and off Alot because the turbine is in a good wind location the mechanical relays can get stuck on due to the result of endless arcing so many point out, Very Good video for beginners, one of the best ive seen.
Thanks for the input! Yes, there are better systems, but keeping a mechanical solenoid cool is key to longer life.
If you have the money, go with the relay unit, though.
The dump load controllers with SSR you speak of are they the ones on the market that only use the AC 3 wires coming in then rectify & control the output to either battery or resistor/dump load? I am trying to take DC from a DC motor wind turbine (DIY) & divert it from the batts once full.
A 3 wire PMA needs a rectifier to convert its ac output to DC, DC can then go to the battery and a digital diverter will keep the battery from overcharge by diverting excess to a dump load resistance.
@@GBear The solenoid shouldn't need a fan. If it's getting hot, it means it's probably not a constant current solenoid, or it's exceeding the rated voltage/current.
@bigrob1887 true, but the fan keeps it cooler. 😆👍
Very nice set up. I spread my panels to separate charge controllers and batteries which each are dedicated to a specific task and load. Also I would dump excess load to a hot water heater inorder to storage the excess. Nice work sir.
Thank you and welcome aboard.
You explained everything so well and now I feel way more confident. Thank you so much.

Good Informative Video Sir.
I have both in the works. 12V and 24V . The wind system being 24V. Most likely will be going with 24V only at some point. No Obstructions here so I can get away with the turbine only being 10Ft above my roof line.
The main disadvantage of using a DC 2 wire Wind Turbines is DC voltage they produce requires heavier gauge wire and does not travel distances as well as AC or Three Wire systems can. They work for stuff like boats but for home use Best to just avoid the things.
Well it's Semi Official. Wife works at Wally World and they was informed today to expect the shelves to start being short. The warehouses are feeling the pain. So if there was a Chines product your in need of at Walmart you might want to think about grabbing it.

Connecting multiple charge controllers _without_ parallel capabilities will work, but it won't work very efficiently and you'll lose out on a lot of power, especially mixing MPPT and PWM controllers.

Welcome aboard Jon!
Been trying to find out more on using more than one solar array and wind turbine system but every where I’ve gone seen to think they can talk the lingo and you’ll understand it. You have answered most of my questions in layman’s terms which I understand. Many thanks And great video look forward to more. And subscribed 👍🏼👍🏼
Welcome aboard! Anything in particular you need to know or clarify, just ask and I'll help if I can.
@@GBear great vids g-bear. My question is more about solar. I’m still stumped on how to divert solar power after batteries are charged. Like to heat water. Is there a simple diverter system that can be triggered by a timer or voltage that doesn’t involve using the batteries. One person mentioned it being necessary to have a switch or relay before the charge controller to prevent micro cycling batteries. Im still very new to all this. Thanks
Hi Spot On. Welcome aboard! Yes, there are ways to divert excess power to heating elements. Below is a link to one type, but the element included with this unit is for air warming. You would need to buy a water heater element in your voltage and subsitute it for the air heater element. I'm not promoting this particular charge controller, just showing you what is available.
amzn.to/3yzDi8s
You didn't mention the size, output, or even how much wind you get at your location, so I couldn't be specific on what you need or should expect from the setup.
@@GBear I appreciate the help, and thanks! it’s a small solar setup for a shed. I’m really just looking for direction on the concept tho. Interesting charge controller! i just want to make sure that the dump load doesn’t pull from the batteries and micro cycle them as some RUclipsrs mentioned some will. Do this “d” terminals carry the power right from the panels or will they pull from batteries? I haven’t seen charge controllers with a “d” symbol on them before
Oh, wait! Are you just using 'solar'? No wind turbine?
Thanks for the video, I have been trying to get info on how to size the wind generator. My off grid system has 3x100 amp lithium battery and 2.1 kw max solar... I need extra when no sun for days but I have plenty of wind.
Welcome aboard Ed! Ok, let me simplify the sizing for you.
Since wind generators seldom put out their rated value for a consistent time due to fluctuations in the wind, get the highest rated one you can afford. You'll still need either a diverter or a good Midnite classic controller, the latter being the better choice. Not all controllers can be used for wind, but the Midnite classic is designed for it and is very efficient at it.
Take into consideration when going with wind power, max output at what wind speed? Also, 3 bladed units are a better design than 5 or 7 blade units, but size and shape make a difference also. The tower or mast height and strength. My little KT5 PMA has pulled a 300+ pound concrete anchor out of the ground in 60+mph wind.
Guy wires need to be steel rope able to handle 3000-5000 lbs of stress in high winds also.
Then consider access to the PMA for maintenance. Simple things like bird poop can throw the balance off, causing excessive wear.
That brings me to another thing...be sure to check your hub and blade balance before installing them on the PMA for best performance and output.
Lastly, consider where the PMA will be located and the distance from the battery bank. Wire size and PMA vs PMG are affected by that distance.
Thanks for all the info G Bear. TAKE CARE..
You are welcome!
Great video. Can you explain how your wind controller manages the power cover to control the power taken from the turbine at different RPM or Voltages. This is important for efficient operation of the wind turbine, especially at low wind speed. Thank you.
@@igorrogelj5033 Welcome aboard.
I'll try in a video soon.

Lol, thanks Tom.
Thank you. I am heading off grid in three weeks and have much to learn. Moving into a home with an existing 1200 watt system, but it's ripe for a turbine.
Go BIG on turbine output, PMA, and be sure to have a solid, steady mast. Balance your blade setup prior to raising the mast for best output and performance.

Building me a vertical wind turbine. Trying to get all the info I can! Thanks for the tips.
Sounds like a fun project! Good luck! Let me know if I can help with info.
I built my own vertical windmill with a treadmill motor. Now I'm just here to see about the control system for the battery bank.
You'll need to determine the treadmill motor output voltage and wattage, and whether your output is AC or DC.
With AC you'll need a bridge rectifier that not only converts the AC to DC, but steps the voltage down to your usable battery bank level. You can't charge a 12v battery with 60 volts DC!
With DC (PMG) you will also need a step down transformer, but not a bridge rectifier.
Oh, and welcome aboard!
Thanks. Yeah it outputs DC. I'm looking into purchasing a 440 power charge controller is what I've read I should use. That with an inverter as the output. I plan on running dc stuff but then a maybe a couple smaller ac things.
Nice project Sir
Thank you! Welcome aboard.
Enjoyed the video.
One thing (probably of many) that I haven't figured out yet is how is the voltage from the pma regulated.
I assume the voltage will vary with wind speed but you need a nice steady 14.5v to charge the batteries.
Welcome aboard. Yes, the voltage is quite variable from a PMA due to wind speeds. The best way to control it is through a Midnite Classic controller after the bridge connector.
I still have mine 'old school' style where the bridge rectifier connects to the battery bank and a dumpload controller monitors voltages in the bank and dumps it if it exceeps capacity. I was going to upgrade to a Midnite Classic controller bit the economy made finances go south.
Comprehensive thank you. I'm wiring multiple charge controllers and mixing solar and wind. This clarified a lot. Thanks.

How we can connect car alternated powered by wind turbine to charge ev car lethium ion battery
Won't be easy! A car alternator is usually 12vdc, and designed to charge a lead acid battery. The voltages of an EV are usually in the 48vdc range.
Pma=AC 3 WIRES. PMG=DC 2 wire ok GBEAR I'M TAKING MY NOTES! All Makes sense! Thanks 👍
Correct. PMG has q built in rectifier, PMA requires a rectifier to be added before the battery connection.
I use a 100 amp 3 bridge rectifier. And a dump control board and solid state relay and 3 100 watt 3 ohm resisters in paralleled to drag mine down when the bank is full.
Great video. Very informative. Thank you.
Welcome aboard. You're welcome.
This was great. Thank you.
Welcome aboard! Thanks.
Got the same charge controller but my model is 2000 watts. 1000 watts for solar and 1000 watts for turbine. Whole system is 12 volts. The problem is I just bought my first solar panel which is 320 watts and it is pumping 30 volts. It is working fine when it is cloudy but in full sun the controller is shoving error and OVER PV is blinking. I found in the instruction that voltage from solar panel is higher than voltage set in controller. What can I do now? Did I buy wrong solar panel. I was trying to set higher voltage in the controller but the max is 17 volts. I do not understand what is wrong as this controller is made for 12volt 24 volt and 48volt systems. Anybody could help???
Welcome aboard Seb, sorry to hear about your troubles. If only you had contacted me sooner. I found out the hard way that those Chinese controllers are junk. I have since replaced mine with the Midnite Classic 150 and wish I would have just gone this way in the first place.
You have a choice, keep that controller and get rid of the solar panel, and only use 12v, 100 watt panels connected in parallel with it, or keep the solar panel and buy a Midnite Classic 150, 200, or 250 for your solar controller and use the Chinese controller for a 12v turbine only.
Note that the numbers for the Midnite Classic depict the maximum input voltage, so the 150 will accept 150vdc input, allowing you to connect your 320watt panels in series/parallel.
Also the Midnite Classic group will control either wind or solar, but only one or the other, not both in the same controller.
I hope this helps.
This was very helpful to me. Thank you for sharing!
Welcome aboard! You're welcome.
Excellent video, thanks so much. More please 😅
Subscribed!
Welcome aboard! You can bet on more to come.
One small correction, the difference is between a PMA and PMG is NOT that PMA is AC and PMG is DC, they are both AC. The PMA is designed for a car originally and the PMG is designed to be a generator and is essentially better in every way.
Welcome aboard. Sorry, I have to correct you. A PMA has 3 wires all the same color, and no specific order of connection, all output, because it is AC (Alternating Current) until it runs through a bridge rectifier which is constructed of a series of diodes and converts that alternating current into direct current (DC) by redirecting multiple inputs to directional input/output. A PMG is a Direct Current "generator" That produces electricity through a 2 wire Direct Current, positive to negative, power with one red and one black conductor. Power out through positive and return through negative.
The correction to your statement is: Both PMA & PMG are "alternators", the difference being, a PMG has a rectifier built in, an PMG requires one at the conversion location. This is why a PMA is preferred. An alternator, (requires smaller conductors) for longer distance of run, saving money on wiring, and conduit sizes.

I don’t kwow what to tell you. PMA is car alternator. It makes AC. The PMG is a 3 phase generator . It also makes AC. The one i have has 6 wires one sour I’d it.
6 wires coming out of it.
Amazing video man, for real this is great information for me, an Engineer student in renewable energies!
Welcome aboard Marcelo! Any way I can help you, ask away! You may want to check out my Playlist about Electrical experiments and such also!
That's what I'm doing, your content is fascinating. I would love to have teachers like you lol. I have a question, I can always connect my wind turbine to a SOLAR CHARGE CONTROLLER? Aren't there charge controllers for wind turbines? If so, Is it possible to connect a wind turbine and some panels to the same charge controller?
@@marceloadrianmendodelacruz5451 yes, there are hybrid controllers that handle both wind and solar. I prefer not to use them from experience. I had to cycle through the controller to distinguish between which was producing what. By separating them out I am able to see those numbers at a glance.
Thanks for the info, that makes sense. I'm currently doing a project for my thesis that consist on perimeter lighting for my University parking lot with eolic and solar energy as power source. Your knowledge is gold for me, I appreciate the help! Greetings from Mexico.
@@marceloadrianmendodelacruz5451 in the near future I will be installing a solar powered submersible pump system in my water storage tank to keep the water in motion during the hot summer days. This should help prevent stagnation and algae growth. I just ordered the parts and should receive them in a couple of weeks.
BLS was a huge tip!
Welcome aboard!
that one green controller takes wind turbines too. i have the same one connected to four 100watt panels and a 400watt turbine
Yes, it is a hybrid controller, but not a good one. Same with the one right beside it.
I bought those in my early days of learning and retired them when I found better, more efficient options.
@@GBear i just got it in February so far its doing its job but yes i will be upgrading in the future as my ranch and the system grow
Smart man! We all have to start somewhere and sometimes learn the hard way. I try to share what I learned that hard way to help others save money, time and frustration. Welcome aboard!
@@GBear i have seen i have been watching the channel off and on for the last year and a half now
Thank you for your continued support.
GBear, another alternative to dumping your excess power, feed that extra power into a secondary 14 volt battery bank by using a combination of 6v & 8v golf cart batteries, which requires more current for charging. I’ve been using BatteryMINDers 2012’s for all five battery banks except one AGM bank that uses the BatteryMINDer 2012-AGM model. My golf cart batteries and AGM’s are between 10-15 years old and only need to add acid once a year. I use two banks for Ham radio that requires 13.8 volts. BTW, a PWG also works as a pulse/desulf charger but I like that BLS-12N and I will see if I can buy a couple of those.
Welcome aboard! I do have plans for a second battery bank, but was thinking more along the lines of 48v as a backup.
Umm you should never shunt of dump into anything that could run out of capacity. You could kill the turbine or your batteries or both or all three: catch things on fire. (10:20 looks a little fire risky to me)
@@fishhuntadventure won't the dump load controller just divert the power when the main battery bank is full?
No. It will turn on when the battery bank is over full, but the AIMS and the Midnite Classic also prevent overcharge, so the dump load never activates any more.
@@GBear GBear, thank you for the reply… it seems your video didn´t just enlighten me, but also a huge pouch of people!
AIMS and the Midnite Classic will prevent overcharge and the dump load will not be used right? The thing is that I do want to use that extra power but not on that huge resistor, I want to use it on a large water heater and/or another battery bank for gest house.
The other thing I´m worried (as I´m using lithium-ion battery) is the micro cycling happening on the battery bank while using the dump load.
Can you please give me some insights on these 2 issues?
curious will it not damage the battery if you feed the output of the rectifier direclty to the battery ? . Again I am not expert on this just asking to expand my knowledge. do you still need a voltage regulator to match the proper charging voltage of the battery ? feed the output of the rectifier to a voltage regulator or PWM or charge controller ? thanks
Welcome aboard! First, let's start with the basics. You should not attempt to charge, let's say, a 12v battery bank with a 24v turbine. Think of it like you car. You wouldn't replace the alternator with one that outputs higher voltage, right.
Now, yes, you 'could' do it using a specific charge controller, a transformer, etc., but it would complicate your system and life, while costing you more.
As far as connecting the bridge rectifier straight to the batteries, yes it will damage the batteries unless you also add a 'dump load diverter' to handle overcharges. You could also use a Midnite Classic charge controller set up for wind power conversion, which is the best option, as this allows you to fine tune and adjust the input for best efficiency.
I believe the 1600 watts is what it will put out for an entire day(24hr) if it ran constantly at its highest output,
Welcome aboard. I'm not sure what you are referring to, but if it is my PMA, it will generate max watts at maximum wind speed, for as long as the wind maintains that speed.
i have set up for my office and one set for the freezer and frig. the 24 will be for the air
Too bad you are on the other side of the country, I'd love to help you with the setup, but from here, I worry about your safety while Jerry-rigging power.
Where do you set up your panels? The Gustapo will spot them and throw you in the cooler.🫡😆
So what are you using for an inverter? You would need separate ones for 12v or 24v. Also the wattage and pure sine or modified sine wave makes a difference.
@@GBearihave 1500watt pure sign wave for the office i have 1000 pure sign wave for the freezers i have a3000 pure sign wave they are relibles for 24v i have a 25000 i have high dollar charge controllers tristar but don,t whant to mess them up they all have dip switches for setting
Good vid & explanation of ur system G Bear. Wouldn’t it makes sense to use ur dump load to make hot water or at least a pre-heater for a hot water system, but use ur excess solar power from ur controllers as well, as soon as ur batteries are full SOC have the controller divert any extra power to ur hot water system. I have a 50ltr hot water system that operates this way on a stationary 40’ bus, a 24v system, 3kw AIO inverter, 2.5kw pv panels & 10 kwh lifepo4. I can run microwave, 2.5kw split air con, H/W system, everything off Solar & heat water for the family of 4 showers daily while fully charging batteries.
I have a 24vdc multi power element (300w, 600w, 900w capable) for the H/W system but never fitted it as I use the inverter with a AC voltage/dimmer control so I can adjust the output to the 240vac 1800w element I installed previously, instead of the 3600w element it had standard. I can use the controller to vary the power usage of the H/w system if its cloudy or for other reasons.
For my house I have a 5kw AIO 48v system with 10 kwh of pv (grid tied) & 30 kwh of lifepo4, I only use about 20%-25% battery SOC a night on either system generally, higher voltage systems are much more efficient if ur going to use an inverter, & use a step down (or up) converter for lights & light loads to save on wasted inverter idle power usage.
Lifepo4 batteries are a game changer now days in so many ways & using a decent shunt ,means you can know very accurately how much power is going in, out & still available.
They were PWM controllers u were trying to think of , it stands for ‘Pulse Width Modulation’, but Im sure u know that. Cheers
Welcome aboard. I live in the hot desert, and don't use much hot water at all. I use a propane, tankless water heater that gives me on demand hot water when needed. It is off 10
5 months of the year.
My tote-cuzzi outside doesn't have a heater either, and the water is at 90°F or better.
at first i thought the fans was overkill but then i remember your in the desert lol
Lol, yes I am! Welcome aboard! Also, that big PMA produces high amps and heat.
G. Bear, I have a three-wire wind generator, and common inexpensive potted wind controller that came with it. All three wires from the generator are the same color: Red. And the three controller wires are all the same color, also. Does it matter which generator wire goes to which controller terminal/wire?, or can the hookup be made in any fashion, and still have the same, best result?
The face of the controller has a diagram of a three-bladed wind turbine blade, with the center wire of the three controller wires coming from the second (middle one) of the three generator wires. If the order of the hookup matters at all, how can I determine which generator wire is that center wire? Or, as I speculate, since all the wires and terminals have the same color, does the order of the hookup to the controller (rectifier) simply not matter at all? In any case, how did YOU proceed, and manage to get a good result in the hookup? Please help! Others here may have this question, too. Thanks!, --Joe / Tucson ARIZONA
@W7DXW Welcome aboard, Joe! A 3 wire turbine is a Permanent Magnet ALTERNATOR, (PMA), and the order of the wires is not a factor in connections.
Those 3 wires connect in any order to the controller you received with it, to the 3 same colored wires on the controller. That leaves a black and red wire to go to the batteries.
You may want to order the following meter so you can monitor the power.

Thank you! for your help, you've done me a great, good turn (and others here, too, I think, who may have had the same quandary and puzzlement that I had, as newcomers to wind power). I was trying to figure-out the connection scheme for days, and was frankly going a bit stir-crazy, with various mental topological twists and turns, trying to figure out if all the connection schemes are (or should be) in fact equivalent. I even resorted to experiment, and tried different permutations of the connections, while spinning the turbine generator with an electric drill, and always got the same voltage output no matter HOW I connected the wires. I couldn't believe my eyes. You've very kindly settled it for me, now. T-H-A-N-K Y-O-U ! ! --Joe / Tucson
@W7DXW You’re welcome. Yes, it can be confusing to newcomers. The good thing is your test shows it is working properly, having the same voltage output on each combination.
The charge controller they provide is basically a bridge rectifier which changes AC to DC through diodes. That's why I recommended the meter. Without a readout screen, you would never know if the power to the batteries was too high, especially with LiFePO4's.
Awesome job sir
Thank you. Welcome aboard!
OMG video panned into his shed there WOW!
Welcome aboard!
How close to the ground can you have the turbines and have them still work OK? I want to be able to put one up but not have it so high up that everyone sees it, because our municipality I don't know if I can get away with it yet. So I wanted to find out what th eminimum height to get these to work typically is? And because maintenance would be easier if they aren't really high up.
Thanks.
Welcome aboard, Noah! If you live inside city limits, they usually aren't allowed. They need to be high up, especially around multiple buildings that would affect air flow. Also, if you are on grid, it wouldn't do you much good anyway, unless it was a very large turbine.
Sorry to sound negative, but I don't want to mislead you.
@@GBear Hey GBear thank you for the reply. I appreciate the comments. You weren't negative but just being real. Actually you are probably right.
I'm curious if they could be used for camping though, or if it would just end up being too hard for a portable set up with one?
@Noah Riding The higher up you put them, the better they work. Solar is a much better bet for camping, as you don't always have wind, but the sun is pretty reliable. Turbines are supplemental providers, and shouldn't be relied on as the main source of power. After all, who wants to camp in 40mph winds?🤔

Welcome aboard, Adam!
Thanks G bear!! great explanation, I’m trying similar project too, POC is done and now will need to design a battery bank.
1) how do you wire the batteries together with 2 source of charging ? I’m thinking to add another source for charging but not sure how to wire it.
2) If it’s a separated batteries zoning , how do we ensure the batteries are equally charge?
3) how do you connect all the batteries to the inverter? Do you have a battery bank management system in place?
4) how to detect a faulty battery under the batteries bank?
Watch tonite's episode and I will answer your questions.
Do you ever have to replace the blades on these turbines? And if you do, will they even be willing to sell them?
Blades can become damaged from elements and other things like bird strikes, etc.
Yes, you can buy replacements from Thermodyne.
The reason automotive/car batteries don’t work well is because they use crank amps. Electric vehicle batteries don’t need that initial inrush of amps to crank anything.
Exactly. Car batteries are designed to give a quick burst of power, then recharge slowly, where electric vehicle deep cycle are designed to release power slowly and recharge quickly.
24v aircraft batteries work well for solar, but are very expensive.

Hi. I am Graham.
How do you connect 2 or more charge controllers to the battery bank. Do you do it in parallel to the same battery bank or you split the battery banks so that each controller charges its on Bank. I have tried putting them in parallel to the same battery bank but one of the controllers always get damaged. Please help.
Hi Graham, welcome aboard. They need to be connected to the bank at different locations, and should be set with the same parameters. Also, only one should have the 'equalization' feature turned on.
Connect the first one, positive to positive of the first battery, negative to the negative of last battery.
Connect the other, positive to last battery, negative to first battery.
Great stuff, thank you! so basically the power from wind is going straight into the batteries ( disregarding the rectifier) not using something like a charge controller like the solar does, correct? Would this same setup translate to hydroelectric, no? (Pelton wheel being spun by water) lastly, where did you get that display showing power and voltage? Or what did you Google for?
Welcome aboard! Yes, 3 phase AC power comes in from the PMA (turbine) goes through a bridge rectifier to make it Single phase DC, then through the "high precision wattmeter", then through a breaker to the batteries.
Then a dump load unit or digital load diverter is applied to the battery bank to prevent over charge.
You should mention with the solar wire the gauge could be less if the panels are wired in a series vs wired in parallel (more amps require thicker wire vs more volts and less amps and letting the mppt controller convert the higher volts to amps at the controller)
Welcome aboard! Very good point! I'll be sure to put out that info.
Well said 🙏👏👏👏 a lot of people make this mistake to parallel panels and they spend a lot of money in the cable but the problem is a lot of people use low amps charger(most of the cases cheap ones) and those they can't take higher voltage input like the midle/premium brands(even though there are quite a few cheap Chinese chargers that can take over 100v input and output 12-24V or more)
Welcome aboard! So true!
just noticed that your wall fan will blow air in the cabin not out... change sides and then it will blow out ;) and your inverter will take air in true front and blow out from back
I don't know what you are looking at, but the fan on the wall near the door blows out. The inverter fan blows towards it and it moves the air out through the vent. The fan on the other side feeds air into the inlet side of the inverter.
@@GBear your bridge rectifier fan blows towards rectifier... wall and inverter fans are blowing same directions... fan sticker is always where air comes out from it ;)

@@GBear I'm a 30 year retired electrician, I always said when I retire I don't want to have a electric bill , well I still do. But I'm looking into going wind and solar. but I'm doing my research first. Just because I'm a electrician I wired restaurants and solar is different. But for the DIY I have a little head start I do understand voltage drop and how to size wire. and a parallel V/S series. The Higher your voltage the lower your amperage. How long do you get out a a inverter.
Welcome aboard Tony!
As with all electrical components there are variables as to how long they last. My first inverter was Chinese made and although it still works I found out the hard way that it's "pure sine wave" wasn't clean. It caused problems with my refrigerator and stove and microwave. It also lied about its capacity claiming 32000 watt surge capability, the in fine print right on the inverter it says it won't handle a pump motor 1200 watt surge. Long story short, avoid Chinese made inverters.
I have since switched to an AIMS split phase low frequency inverter and am loving it. With proper care, not to overload it, keep it clean and dust free, I expect a long lasting relationship with this inverter.
You are awesome, thank you

You should blow air in from outside, not suck 'hot air' out heat rises. Your extraction fan is too low and will actually bring the hot air from the ceiling down past your inverter
Welcome aboard. Yeah, but if I am doing it wrong for the last almost 9 years, and it is working, then I see no reason to fix it.😀
Question. I'm looking at the KT5 on their website, they say in high wind gusts it can produce up to 68V peak on the 12V model. It looks like their rectifier is rated to 1600V, but what would happen to the batteries? would it just trip the load dump solenoid?
Yes, but solenoid dump load systems are no longer used. Digital diversion units are the new wave. I live in a high wind area, but have yet to see more than 60amps and 880watts, and that was with 45mph winds. That's 14.6v. I was told the same thing as you, but can't figure out what they are talking about. A 12v PMA is a car alternator, and it would never put out more than 14.7 volts, even if you were driving 120mph with 5k rpm on the engine. I think they hype the product to sell more product.
I bought their meter unit to monitor output and it failed in a short time. They gave me all kinds of crap about how it was my fault, etc., then it mysteriously got lost in the mail and I was out the money and the meter.
I bought a Chinese meter and it has been working fine ever since.
@@GBear Thanks for the info!
When you need to replace your batteries do you think you will go with Lifepo4 batteries? They are getting cheaper all the time.
Thanks for the video.
Welcome aboard! Not sure about that. The extreme temps out here are not good for LiPo
If you have some strong young and very good friends an earth bag structure might be an option. Maybe one for the batteries and one for the other equipment. The equipment room could heat the battery room. Eg4 now has a self heated battery, I think it is 13kw and is about $4000. Maybe a suggestion for someone starting out that could be expanded on. Maybe a subject for your new paid channel.

@@JR-xw5dk Thank you for the information. I'll at least do my research so I know what I'll be dealing with in the future.
Not anything I have tried but just something I thought about. If you can get the right thickness of wall you might get it warm enough for the winter and then cool enough for the summer.
Maybe do earth bag work shops. Get people to pay you to work for you. 😂
@@JR-xw5dk lol, thanks. I'll keep that in mind.
This all seems so complicated, and depressingly difficult. Do they make/sell ready-to-go systems, for people of low-tech understanding? Do I really need a shed full of wires and gizmos to get a wind turbine working? I'm looking for a simple setup where the wires from the wind turbine plug into one "box", then the output from that "box" is a cable that I can plug into my portable battery/generator to charge it. This is how it works with my solar panels.
Welcome aboard. Yes, times have changed. You can use a Midnite Classic charge controller after the bridge rectifier. Then just connect the Midnite Classic to your battery bank like you would with solar.
Thanks so much for the information.
You're welcome, and welcome aboard!
I enjoyed watching. Please I have some questions
Ask away!
the green mppt has turbine input and dump terminals. have you considered buying another one for the turbine? or is the turbine greater than 600 watts. that green mppt is also available in 1000 watt model too. then you could get rid of the black pwm and its solenoid and use the all in one green controller to open and close the dump load.. also what about getting the 12v water heater element for your water heater tank to further alleviate grid consumption? heck its free energy. might as well right
u definitely know what you are doing but you dont get any gold stars for organized wiring lol haha. good video tho. very helpful. thanks
Welcome aboard! My turbine is 1685watts. Those hybrid controllers are junk. I learned the hard way on that. I have since upgraded to a Midnite Classic controller for solar, and still use the dumpload as backup. But it never activates anymore because the Classic monitors the battery bank. I also have a tankless water heater so I don't need the preheated setup.
You are in the early videos still, and you will see alot of advancements in later episodes of my playlist.
Yeah, the wiring isn't pretty, but it works perfectly, lol.
Thanks for your thoughts though.
@@GBear thanks , i will continue to watch. with the classic, when it shuts off charging to the bank, and you are rarely using the back up, how are you preventing over-speed without keeping some sort of resistance on the turbine?
@toobglued the turbine is connected directly to the battery bank. In the future I will be controlling it through its own Classic, which will make it more efficient.
what is the point of having a PWM module connected to the batteries to dump extra power if the power reaching to the batteries from the rectifier are already charging your batteries, won't they get damage over time more quickly provided there is no controller before power reached them after they peek in power? it seems to me that the PWM controller should go after the rectifier to charge your batteries and not later, not a criticism, i'm wanting to build a water wheel generator with either a PMA or PMG and its a bit confusing with all sort of information in the internet on how to connect stuff
Since a PMA or PMG can put out excessively high watts and amps at times, running it through a controller requires a special controller to handle those ranges. I have seen my PMA put out 166 amps, and actually fry the rectifier which was rated at 150A.
The PMA is specially designed to operate a 'dump load' system, which puts a 300w load on the battery bank when excess power is created.
Welcome aboard.
how did u ground your wind turbine? where did u attach the ground wire? my wind turbine is 20 feet up its on water well poles. how would i go about grounding it?
Drive a 6 foot ground rod into the ground if you don't already have one nearby, then attach the metal tower to that ground rod with at least #6 solid copper wire. The PMA or PMG is already in contact with the metal tower so no wire is needed at that connection.
Welcome aboard!
Hey FRIEND! Touching base with you! Interested in learning how much power it generates. It 12volts you say. 1685 watt??? Got to have 90 mile/hr wind…that is rare!
Needs 90mph wind to produce 1685w. It starts producing at 9mph, but only about 30-40w. Normal winds here will reach 22mph and I can get a few hundred watts out of that. I have seen over 1000w in a wind storm with gusts of 45mph.
Hi, G Bears
I have 12v 105Ah 5 battery (525Ah). How many watt solar panels do i need to charge them? Thank you
Welcome aboard! Just to charge them? Ok, I can see you are new to this, so let me help you understand more about solar.
To charge a battery bank of any size, any size solar panel will supply a charge.
To keep them charged as they may need more input. For a more accurate answer, more information is needed.
1. What will you be powering with your battery bank? 2. Are your batteries Lead acid, LifPo4, AGM, etc.? 3. Deep Cycle or Standard cycle?
525Ah only means you can supply 525 amps for 1 hour at 12 volts. Or , actually 1/2 of that. Because you only want to discharge a maximum of 50% of battery capacity.
That gives you 3150 watts for one hour. (Amps times volts = watts) but remember, you will lose some of that just powering an inverter 12v to 120v.
Heating and cooling appliances use a lot of watts, LED lights use very little watts.
You need to total all the watts needed by your load, before you can determine how many batteries you need, and how many solar watts input you need, then what size charge controller and what size inverter you will require, keeping in mind that once the sun is gone at night, the battery bank will have the sole job of powering all your electrical needs without any help.
@G Bear's Off Grid Ways-A Homestead In The Desert Hi,
I am completely new for this knowledge. My main use for washing machine 240v 2500w with hot washing and
I have 5 AGM battery's 12v 105Ah each and 3000w inverter.
Thanks
Ok, your battery bank is too small to run that washer after dark, and to run it during a sunny day you should have a solar array of at least the size of your load plus 20%. That will allow charging of the battery bank while powering the load. The washer will use 10.5 amps during standard run. Heating water will be a large draw.
Using 220v, I assume you are in Europe?
Your better choice would be 6 batteries connected series parallel for 24v, but then you would need to change your inverter to a 24v unit.
Anyway, using 2000w of solar panels may allow you to operate the washer at peak sunny days. Connecting the panels in series parallel to increase the voltage will help also, but be certain not to exceed the charge controller's maximum voltage limits. You could possibly get by with four 305w solar panels, with 2 strings (connecting 2 panels in series, times 2) into a Midnite Classic 150 controller or equivalent since it will handle 12 or 24v input up to 150v. Just remember, always connect the batteries to the controller FIRST, then connect the solar panels, but dont do it while the sun is on the panels. Cover them.
As a simple rule, to calculate
how long a 12v deep-cycle
battery will last with an inverter
multiply battery amp-hours
(Ah) by 12 to find watt-hours,
and divide by the load watts to
find run time hours. Finally,
multiply run time hours by 95%
to account for inverter losses.

You don't mention that another advantage of the AC is that the current in the wiring is smaller so you have less line loss and can use smaller Guage wiring.
Welcome aboard Ron. Maybe not in the video, but I have mentioned that often in comments.
Good comment, though.
Do you ever have an issue with your PMA when you connect your battery bank PMA start swinging slowly and as soon as you disconnect the battery bank your PMA turns faster?
You should never connect or disconnect a PMA under load. The blades should be tied so they don't spin, then released after connections are made.
The PMA connects to the bridge rectifier on the 3 pole side with wires in any order, but the output side of the rectifier with 2 poles are marked + or - and polarity is important when connecting to the battery bank.
So, answer is no. I don't make or break connections while the PMA is spinning, so I won't see what you described.

Hi G Bear, I’m getting a 24v wind turbine and I already have 6x12v batteries, do I get a 12v inverter or 24v, much appreciated.
Welcome aboard. First, you didn't say if your turbine is 3 wire PMA, or 2 wire PMG. You also didn't mention if your turbine has a controller, or not, and you didn't say if you also had solar coming in. If you plan to use the turbine, you MUST configure your battery bank to 24v, use a 24v controller if you also have solar, and a 24v inverter.
The solar controller gets connected to the 24v battery bank FIRST, then connect the solar panels.
If you are not using a charge controller for your AC turbine, you will need a 24v bridge rectifier between the incoming 3 wires of the turbine and the battery bank.
If your 24v turbine is DC (2 wire, red and black) it can connect directly to the battery bank of 24v, but a dump load diverter will also be necessary.
Thank you for a very quick reply, I have ordered the ista breeze turbine kit i1500, with the controller & dump load .hope this helps.. thanks .
Are you planning to have solar also, or just the turbine?
Sorry forgot to mention yes I have a few solar panels, it’s 11pm here . I’m half asleep 💤
Yes if it’s safe to link up
