You basically just proved that a BMS is not really necessary. With batteries with such low internal resistance and wires cut the the same length...I believe it will boil down to a maintenance issue 3 or 2 or 3 times a year.. great job man.. love the videos .my inverter is coming in the mail. Can't wait to move forward with my own set up
I'd love to see some pictures of your setup, I'm on facebook if it is easier: facebook.com/DavidPozEnergy/ Also, check out this video Mark made. He has been using batteries with no BMS for over a year. ruclips.net/video/si-8N972A-U/видео.html
That's an excellent choice they make a very fine products. There was a gentleman online their name is Morton's on the move he did a complete install of Tessler lithium batteries in his RV he's an electrical engineer and developed a very safe user friendly system.
That’s because when they go wrong, the manufacturer steps up and deal with the issue in a professional manner so no one feels the need to complain to everyone in hopes of getting a response
They do look great. I think I've read all their spec sheets and the closest to fitting me would be two quattro 48/5000. I would need two to get the 120/240 split phase. Unfortuantly two of those inverters winds up costing about $5600. I wish they made a split phase in one unit. I did think about buying their quattro 10000VA 230v and then using my transformer. I have a video where I tested this idea and found my transformer uses 100 watts in idle. Too much of a load. Have you seen that video? It's here: ruclips.net/video/P4Wm83vsdKc/видео.html
The midnight classic is a awesome controller. I didn't know how good it is until recently. It is adjustable from 10-100v out. And 96amps. And it can be over driven. Where you maximize for lower sun. To get more power with out burning controller. It will not do more than 96a even if 10,000 amps is available. I'm thinking of getting one.
Set absorption voltage (=max voltage) slightly above floating voltage (~0.3 V) to avoid a "battery voltage to high" error in some cases, like when a high load is turned of while charger is floating and voltage is bouncing back over max setting you entered
Thanks for the tip. I'm just learning, so I appreciate the help. Just to clarify, is your suggestion for the lithium batteries I have, or for typical lead acid? Thanks.
I have a 48v lithium system which is charging while a pool pump is running. So if the battery is in foat and the pump would stop, the voltage would bounce up a bit. If the floating voltage is same as the max voltage you set for absorbtion, the charger would stop with a overvoltage error and you just lose some sun hours till the system starts up again after a time out typically...
Victron make top products. Great choice...... cooling fans are an advantage keeping electronic components cooler there for extending the life off your device. All my solar products have cooling fans.
Thanks for the video. Your kid is learning solar at an early age. Nice!! I'll be installing our Victron 100/50 tomorrow morning. I'll try doing a video if it's not rainning. Thanks again.
David, I use a Victron 100/15 charge controller to charge my 1kw Chevy Volt battery. I also us their 500w inverter. I love these products and I am constantly looking at the app on my phone as a curiosity.
Hey David good job so far just started watching you and the Volt powerwall setup. You got a high end Victron Charge Controller that can handle a lot of solar input however your inverter is lacking if you want to run any kind of Amp hungry tools like your compressor. The inverter you have is just what I call Point Of Use inverters and true high end Off Grid Inverter like ones everyone else mentioned will handle that load just fine. A 4-6kw Magnum, Outback, Schneider, SMA and if budget is concern an Aims inverter will work but they are flakey now. The Aims Chinese knockoffs will work in pinch like GTPower. John
Hi John, I agree with you. Basically I am buying the components as I save up for them. I don't expect much from the cheap small inverter. I look forward to buying a larger, whole house inverter from one of the companies you mentioned. Since those are going to run into $4k, they will take a while to save up for. The cheap inverter allows me to start using the powerwall now, which I do. Back in my video about the Reliable inverter ruclips.net/video/me0eAJL95og/видео.html Which do you use, or recommend?
Nice I have a smaller version Victron 100/20 Solar Charge Controller MPPT, works great. BTW I had no issues with the app on My Android Samsung S7 Edge. Thanks for the info. Keep the videos coming. Greetings from Spain ;)
@@Wallabynge or Latronics, also from Straya......with impressive start-up current, even handles my house a/c. …9 years of continues use, never missed a beat.
Great! Look forward to seeing it running with all the panels. As I tried to explain in a previous video, if you connect all the cells of the same level in parallel, then you'll only need 1 decent BMS, not 8!
Don’t look now but there is a Beautiful Woman on you number trying to pass you up. I heart that the Alt store had bad customer service. Love miss Amy’s Instructional Vids she has taught me a lot. Best of luck. P.S. get a BMS.
Hi Jim, To give you an example of why I like them: When I went to buy a disconnect/combiner box ( ruclips.net/video/IJluk4U8pys/видео.html ) I asked for a particular model box, and circuit breakers. Then one of the sales guys (Adam) came out from the back to talk to me. He recognized that the model box I asked for came with a combiner bus bar meant for 150V breakers, but I was asking for 300V breakers. After clarifying, he changed my request to a slightly different part number that came with the correct busbar. He saved me a return trip. I didn't know there were different part numbers for the parts inside the combiner box.
Aaron Anderson my farther has built 35 boats over 4 years with all victron gear including 3 165ah lithium batteries for a boat hire fleet They’ve not had a single failure
Have you looked into doing an AC coupled system with those SMA Sunny Island? More efficient because you would use the power from the solar panel directly most of the time through compatible grid tie inverter.
Have you looked at REC bms’s? I bought one for my nissan leaf battery. It can will replace your 712 meter and shunt, it also “speaks” over the Victron CAN bus and talk to a GX and I’m pretty sure it’s inverters.
Would this system work on a smaller 12V LifePO4 battery system but will be upgrading to a larger 48V when more solar panels arrive. I don't want to purchase a separate charge controller - .... and I want one charger to work on the small system until more panels arrive and I connect additional batteries. It seems like this would work - but just want to check .
Hi David great vids How you set-up bulk ,flot, absorption to your litium battery? I'd like to use lifepo4 15s bank to charge it to 3.50v per cell what would be your advise to setting? Much appreciated your reply Thank you
Hi Pawel, I used the "User Defined" setting. This allows you to your own voltage. So if you want 3.5 volts per cell, times 15 cells, then your charge voltage is 52.5 volts. You can set this in the User Defined section. In this section there is only absorption and float. I turned off equalize. Set Absorption to what you want (52.5v in this case) and the float slightly lower. Maybe 52.0v. Last, turn off "temp. compensation" which could over-charge the battery if the charge controller senses low temp.
Thank you much appreciated Do you have any sponsor page I don't mind to chip in few bucks Great videos and the way you approach to all what you do I've added you to my watching list
I'm in the affiliate program in Amazon: amzn.to/2O2tptA . I'm also in the affiliate program for Battery Hookup: www.batteryhookup.com/?rfsn=3333666.ca06e9 I appreciate any time someone uses the links. Thanks.
Great I'll take a look I'm having issues to set equalisation to zero or to disable I've looked everywhere on manual, I'm thinking if the victron 100/20 48v I have is not faulty Would you suggest to check for current firmware etc Thank you
Victron Bluetooth only seems to work with half the phones you throw at it. I tried 3 Huaweis (no dice). Works with Samsung A5, Tab 4 and ZTE A520. It's going to be a major problem 7 years down the line, when you find nothing works. One thing that worries me is that amateur installers will not worry about configuring 200V panel arrays. This DC voltage will sustain a 33mm welding arc, which can burn your house down. Must say I'm mystified what those 2 panels could be, that yield 623W. My panel yields can be about 75% of rated value, due to heat and wiring losses.
Hi David, Thanks for your videos. I am looking at your videos and of others, and websites of victron midnite and magnum energy etc, and I can't seem to find a charge controller that does both wind and solar. I am a complete newbie at this, and I am trying to plan for an off-grid cabin that will be up in a couple of years. Thank you to you and your fans for this community.
To my knowledge, there is no charge controller that will do both solar and wind at the same time. You will need two charge controllers, one for solar, and one for wind. I don't own wind turbines, so I'm not a good resource for information. But, I think I have seen Midnite Solar charge controllers used with wind. Or, sometimes you order the wind turbine and it comes with a charge controller in the kit.
Hi, Cool video. I am planning to build a solar panel facility of app. 12kW using Victron products as “brain parts” as you show. The challenge for me is following: I will use 4 x 5,3 kW Tesla Model S 24v batteries serial connected to 2 x 48v as hybrid power bank. Also use the 20/80 % load rule of the battery and apply to max 50v and 37 v as cut-off values. In Denmark we use 220v 😉. I am unclear witch Victron products I must buy in order to build a on grid system able to handle the Tesla batteries? Can you help me?
Not all Bluetooth implementations are equal. My wife's fitbit has trouble with both Samsung and Huawei. The Victronconnect app works fine on an ancient note2 and on my new Huawei but fails on the s4 mini. That's to say, it might be a combination of the phone and the older firmware on the Bluetooth interface. These controllers always ship with slightly older firmware. You are expected to update them at install time.
HI David, I did comment on one of your other videos, You do not need 8 BMS's you only need one, I stated in the last one that you can look into the Batrium range of bms's they upgradable, that means that you can get the watchmon controller and as many longmons as you have cells that need managment, please contact batrium for assistance they are SUPER helpful and VERY knowlagable...... I just can't state enough that you need a bms for lithium.... Regards Charles.
I believe the app can not show graphs of voltage and current (the daily bar graphs are too coarse). Pity. Is anyone aware of a charge controller that does?
You are right, if I was to move too many amps too quickly in or out of the batteries they could overheat. The good news is that running a tool and AC in my garage is nothing compared to moving a car down the highway. I'm not pushing these batteries at all.
You need Low Frequency inverters if you want to start a motor, or something with a motor in it eg: compressor or AC unit. They use proper transformers in them unlike the high frequency inverters which just use electronic trickery to barely run at their rated power, if at all.
While you don't have much use for all of that enery stored in the batteries you should limit your charging voltage to 4v per cell. Being high state of charge for a long time does increase internal resistance of the cell
Love your clear explanations and videos. I have 2 separate Victron 5 KW 48 volt inverters, connecting to 2 separate locations with breaker boxes, 110 volts each. and total of 16 deep cycle batteries. Can I connect both inverters to same battery bank using a large bus bar? Thanks so much.
Is it possible to control how much energy is transferred to the grid? I guess there is a fixed output of 300 W, 600 W or whatever. But is there any chance to control it?
for power tools I would go 6000w, 3000w is just to small for almost any power tool with a large startup load. anyways love the video, be careful overloading the inverter that long after its warm they have a much higher chance of blowing.
Thanks Going Off Grid. OK, I will certainly heed your warning about the inverters. I haven't seen anyone else with your experience with this "Reliable" brand.
also try using a 50' extension cord this will allow the voltage to drop and the inverter may start the load, I have done this many times and it works a lot of the time, and you can open the inverter and turn the voltage to 126 volt this will allow more power as well,
D G Roberts, Yep, they do claim that. I wish they stated how many seconds that surge is for. With Magnum, Schneider, and Outback they will tell you in the spec sheet. Victron just says "Peak Power" with no time.
Well my trail and error testing was running a small fridge. The startup power required is 725w. My original Victron inverter was 300w max. It failed 9 out of 10 times. I upgraded to a 500w inverter from Victron and it has not failed on over 2 months of use. The 500w is rated to 900w peak. Now I was fortunate to have a friend in town who supplies these and could just exchange for the larger inverter (paying the $ difference of course) I encourage you to to look at bobolinksolar.com Although he is in Ottawa, Canada, he is installing whole home Chevy Volt power walls and has overcome many obstacles including the BMS issue some posters keep pestering about
10:01 Are all the holes on the face-plate for venting/screws? I am wondering if the circular ones might be connected to each cell to check voltage/screw connection during initial install. Not really sure if that made sense... Looks like a great system. I am big into upcycling and repurposing things as well as solar in general. Glad I found your channel.
Hi Dakota, I not sure which holes you are referring to, but here goes... The battery shelves are made of slotted steel angle. That is made with holes and slots to allow different bolting options. Or, if you are referring to the 5 large holes in the bottom of the cabinet, then those are to allow venting when I install Plexiglas on the front. I hope one of those helped. Thanks for watching.
hello whats the limit conexion of modules i can do with this 5800W regulator ? 5 serie and 3 parallel? if the power of each module FV es 370W 5*3=15 module*370W=5550W this is correct? thank you for the vidio. Greetings from Argentina
Most sites I've read say a BMS is very important with lithium batteries, however there are some RUclipsr's I've seen without them. I suggest them to err on the safe side.
Curious why you said you can only run 4 panels in series. It is 250 volt, so your typical 12v panel should be able to run 6+ panels right? I thought I read somewhere in the online manual that you could run 10 in series and if it got too cold you just lost some efficiency. Am I wrong?
If I were building the battery today, I would buy these: batteryhookup.com/products/li-ion-lifepo4-3s-20s-30a-bms-with-balance?variant=42283333910690 They are affordable, and good quality. The Chevy Volt battery breaks down into 8 individual batteries, each with 12 cells in series. So, I'd buy 8 of the BMSs, remember to select "12s li-ion". These BMSs are limited to 30A, which means 240A for the whole pack. If you need more current for your inverter, then Battery Hookup has a 100A version as well: batteryhookup.com/products/12v-lifepo4-smart-bms-w-low-temp-cutoff?variant=36287975391394 Use discount code: DAVIDPOZ
Great video. ...on my magnum inverter I can run my mig tig and stick welder no problem but I don't no if I can use the ion batterys with it....great video thanks again
If you are connecting your PV panels in series, then you will get the same amperage no matter how many (assuming they are the same). So you can use the same cable for 2 or 12. This is the main advantage of higher voltage configurations (in series) vs high amperage (in parallel).
Hi Jarek, Thanks for watching. As for my comment about only two panels to keep the amps lower, I was reffering to the battery side. The MPPT charge controller drops the volts down, and increases the amps. I was using a piece of 12 AWG wire.
Hi, i have 4 solar panels for a total of 400W, same specs (21V 5,65A shortcircuit), but i've noticed something strange, if i connect in series (2 couple of parallel and in series, 42V 10A) or all 4 in parallel (21V 20A) i only have a total of 240W, the problem is not the cable because i try to shortcircuit in the back of panels or near the charger, same results. The weird thing is that se single output panel when i shortcitcuit is 5A, but when i put all togheter i have only 3,8A, same thing with real MPPT or cheap PWM. Thank you very much if someone know how to help me :)
Yes, a quality tablet is usually expensive, but there are many low-performance simple tablets out there. The screen won’t be gorilla glass. They tend to break if dropped or abused, but for the very basic functions like email, internet browsing, simple audio and video - they are okay.
There are a few inverters on the market that allow for off grid, and back feeding at the same time. Sol-Ark is the big one that comes to mind. But, for me, I'm happy using all my solar off grid, and just using the grid as a back up to my system in case I don't produce enough solar. This means I don't back feed, but I can draw from the grid when needed.
thanks for the video, very informative. I have a question though do you need breakers to connect from the battery to the controller? I just bought a PWM 60 amps charging system which I connected to four 100w solar panels, should I add breakers and if I should which type of breakers? thanks
Hi Otis, Thanks for watching the video. Circuit breakers serve two functions. First, they add a level of safety so if something shorts out, or is overloaded, it trips. Second, it gives you a means of disconnect so it is easier to service part of your system without shutting down everything. I think it is worth it to install them. I buy mine from www.altestore.com I'm not affiliated with them, it's just where I buy my stuff. If you call they can match you up with a circuit breaker properly sized for your solar voltage and amperage, as well as your battery. The breakers I have are made by "Midnite Solar" and are DC rated. As an example, here is the breaker I have between the solar and charge controller in the video, however this is not necessarily right for your application. www.altestore.com/store/enclosures-electrical-safety/overcurrent-devices-fuses-breakers/din-rail-circuit-breakers/din-rail-mount-circuit-breakers-p40906/#GENBRKDIN-15
Thank you. I am at the learning stage. I have purchased some panels. I will probably pick up that brand of controller too. Would you recommend the Volt Battery over the Tesla Battery packs? I seem to have easy access to the Tesla batteries at $1,250 each.
Hi Bill, I'm glad the video can help you with your setup. I do not recommend Volt over Tesla, or the other way around, they can both work great. I have not used the tesla batteries myself, but from what I can see they are very easy to wire up. I had to modify the wiring in the Chevy Volt pack (check out the video) but with the Tesla I think they are good to go from the start. So that is nice. But, the Teslas are a bit more expensive.
Really enjoying your videos. :-) I am running the Victron 150/70 controller with 1800W of solar to a 24V Li-Ion battery bank from an EV. I am curious what settings you are using for absorption and bulk. Since I am running 6S, I just set them both to 24.6 (4.1V per cell) and feel this could be better optimized. Thanks!
Hi Doug M, Right now I'm not cycling my batteries very much, so I am using 4.0 volts per cell x 12 cell or 48.0 volts in absorption. Then I'm running float at 47.7. This was recommended by "The Hillside Pranburi" and made sense to keep the charge controller from short cycling between the two modes.
Sorry, I should have clarified in the video. MPPT stands for "Maximum Power Point Tracking". This allows me to use a high voltage solar array ( up to 250 volts) to charge a low voltage (48 volt) battery. Not all charge controllers have this ability to drop the voltage down. Some charge controllers are called PWM (Pulse Width Modulation) and for them you need to match the solar array voltage to the battery voltage. BMS stands for "Battery Management System" which is an important safety device when using lithium batteries. I have lithium batteries and should install a BMS. The BMS can monitor and balance each cell in the battery. I'm actually just learning about BMS's myself so I'm not a great resource to learn about them.
If you have a 12S Li-ion battery system, shouldn't the charging voltage be 50.4V since each cell is 4.2 and 12 in series is 50.4V? Is there a way to set the charge controller to this exact voltage?
Hi redstone craft guy, You are right. 4.2 volts per cell is the maximum voltage per cell for this type of battery. The Victron charge controller can be set to exactly 50.4 and does an excellent job stopping there. I'm keeping my voltage a little lower at the moment because I have not yet installed a BMS. A BMS is "Battery Management System" and offers safety when maxing out the charging. Thanks for watching.
@@DavidPozEnergy If you don't need the extra 20% capacity, keep it at 4.00v per cell you will get about 4x the cycle life at that voltage compared to 4.20v charging.
I forget what I used in this video, it was just testing. But, when I hooked it up to my main house battery I used 125A circuit breaker and 1/0 wire. Thanks for watching.
You got it wrong homie. You can connect as many solar panels in series as you want without it affecting then amperage. Voltage stacks in series, amperage stacks in parallel. So whatever wire you are using for 2 panels , you could use for 100. This is exactly why power companies use 500KV lines for distribution. It allows them to keep the wires skinny and not waste so much energy heating transmission lines.
Hi UltraStoat, Thanks for watching. I'm sorry if I wasn't clear in the video, please allow me to explain what I meant. The wire from PV to controller is fine, you are right there. However, I meant the wire from controller to batteries was too small. My solar panels are 365 watts each. If I had strong 4 together, that's 1,460 watts. The MPPT charge controller would drop the voltage down to 48 volts, making the amps to the batteries 30.4a. (1,460/48) 30.4 Amps continuous is too much for the 12 AWG wire I used (that yellow romex wire). That was my limiting factor.
Hi DavidPoz, so one thing that I read when I was looking into Victron charge controllers was that you couldn't install them on heat conductive "substrate." What did you end up mounting it to? I am trying to determine if the device gets too hot, and could catch whatever it is mounted to on fire.
I had mine mounted on plywood for 2 years until someone pointed out to me the requirement. So I added a piece of thin aluminum (white aluminum flashing) between the charge controller and plywood.
Check out Batrium if you haven't already for BMS possibilities. Expensive but just... so full featured. Or, slap some Chinese BMS boards on there and call it good.
Hey David, since it has been almost a year since you put in the Victron, What is your opinion of it? have you have any problems and have you had to call tech support? I hear that Victron is great, but sucks if you have to call customer support. I am looking at buying Victron.
In the very beginning I could not get the charge controller to talk with the battery monitor. They are supposed to. Victron did get back to me (e-mail) but just told me to contact my supplier. Luckily, I had purchased it through Alt-E. Alt-E has amazing customer support. I spoke with Alt-E about the problem, then they went to investigate, called me back a couple hours later with a solution. Perfect. No problems since. I am not affiliated with Alt-E, just a happy customer.
I have the victron demo app, and I cannot see where you can change what type of battery. Do you know if you could charge nickel metal hydride batteries?
Hi DIY Dan, There is not a pre-programmed option called nickel metal hydride. However, there is also not a pre-programed for lithium 12s, which is what I'm using. What I did was select "User Defined" and input my own parameters. I set mine to limit the voltage to 48.6 volts, which is 4.05 volts per cell in my setup. At first the charge controller would go a little over this, until someone told me about the "temperature compensation" built into it. It's on the same settings screen for the battery, just lower. I turned the temperature compensation off. If you know the charging voltage for your Nickle metal hydride battery you can also program that it. I hope that helps.
Yes. This is an affiliate link to the exact model I have: amzn.to/2YK6eJM It has been working very well and I would recommend. If you don't need 100 amps, then you can save money with a smaller amp model.
Hey : Love your content keep it up :) Quick question for you, I have some 40V batteries that are BAE 200. Would this Charge controller be able to handle it? Can you set a defined max voltage on them or do you have to choose from 12v 24v 36v 48v? Thank you very much!
Hi Maxime, On my app I can set a maximum charging voltage, it will not go over that. I showed the range in the video, which is 39.00v up to 69.56. I can actually go lower if you select 12/24/36 volts instead of 48 volts, but I'm using it at 48 volts. I don't know the details about your battery, but if you want to set a maximum charging voltage of 40.00 volts, then YES, it can do that.
No, you can't set a minimum discharge voltage on the charge controller. This is because when you are drawing off from the battery you are not drawing through the charge controller. However, some inverters can be programmed to the minimum voltage before shutting down.
Appreciate your videos, very accurate, i am also building a volt battery setup and i’m gonna use a victron mppt controller, if you don’t mind telling me what charging parameters did u use on your setup
No problem at all. Good luck with your build. My batteries are arranged 12s, or 12 cells in series. I'm choosing to limit my charging to 4.1 volts per cell. So multiply 12x4.1=49.2 volts. Inside the app, I select "User Defined" then I set the Absorption voltage to 49.2v. Next I set my Float voltage to 48.9v. I set this 0.3 volts lower to prevent the short cycling from loads pulling down the voltage temporarily. This is just what I do, but some people like to adjust slightly one way or the other. The main safety thing is that the cells should never go over 4.2 volts per cell or risk damage/fire. I hope that helps. Thanks for watching.
Hi akram hawere, Thanks for the suggestion. I had tried that, along with several other suggestions I found on blogs. Nothing worked until I updated the firmware. Now the charge controller will connect to my android even with GPS off.
In this video it was two panels in series. I'm currently working on my big array with 12 panels. That will be both series and parallel. That video should be out in the next few days.
You basically just proved that a BMS is not really necessary. With batteries with such low internal resistance and wires cut the the same length...I believe it will boil down to a maintenance issue 3 or 2 or 3 times a year.. great job man.. love the videos .my inverter is coming in the mail. Can't wait to move forward with my own set up

I have the 150/100. Its fantastic. Im running a 1000w system, to a 1040amp 12v battery system
I’ve heard no bad things about victron controllers thinking when I get my system buttoned up I’m gonna get one great video sir
That’s because when they go wrong, the manufacturer steps up and deal with the issue in a professional manner so no one feels the need to complain to everyone in hopes of getting a response
Get yourself a Victron inverter they have awesome startup ability and are virtually bullet proof
They do look great. I think I've read all their spec sheets and the closest to fitting me would be two quattro 48/5000. I would need two to get the 120/240 split phase. Unfortuantly two of those inverters winds up costing about $5600. I wish they made a split phase in one unit. I did think about buying their quattro 10000VA 230v and then using my transformer. I have a video where I tested this idea and found my transformer uses 100 watts in idle. Too much of a load. Have you seen that video? It's here: ruclips.net/video/P4Wm83vsdKc/видео.html
I cant get over the baby adorable
The midnight classic is a awesome controller. I didn't know how good it is until recently. It is adjustable from 10-100v out. And 96amps. And it can be over driven. Where you maximize for lower sun. To get more power with out burning controller. It will not do more than 96a even if 10,000 amps is available. I'm thinking of getting one.
Yeah, there are lots of good controllers out there. I've heard great things from the Midnite classics as well.
The show stopper is the wizbang jr. No one else has stop absorb by amps.
@@unyalliman Does the victron not use end amps with their shunt?
Set absorption voltage (=max voltage) slightly above floating voltage (~0.3 V) to avoid a "battery voltage to high" error in some cases, like when a high load is turned of while charger is floating and voltage is bouncing back over max setting you entered
Thanks for the tip. I'm just learning, so I appreciate the help. Just to clarify, is your suggestion for the lithium batteries I have, or for typical lead acid? Thanks.
I have a 48v lithium system which is charging while a pool pump is running. So if the battery is in foat and the pump would stop, the voltage would bounce up a bit. If the floating voltage is same as the max voltage you set for absorbtion, the charger would stop with a overvoltage error and you just lose some sun hours till the system starts up again after a time out typically...
Ok. Thank you for the clarification and help.
Victron make top products. Great choice...... cooling fans are an advantage keeping electronic components cooler there for extending the life off your device. All my solar products have cooling fans.

Thanks for the video. Your kid is learning solar at an early age. Nice!! I'll be installing our Victron 100/50 tomorrow morning. I'll try doing a video if it's not rainning. Thanks again.
David, I use a Victron 100/15 charge controller to charge my 1kw Chevy Volt battery. I also us their 500w inverter. I love these products and I am constantly looking at the app on my phone as a curiosity.
Nice.
Nice video! Glad to see your helper there to keep you company. :-)
your kid is so calm and watching everything you will have future helper there
Hey David good job so far just started watching you and the Volt powerwall setup. You got a high end Victron Charge Controller that can handle a lot of solar input however your inverter is lacking if you want to run any kind of Amp hungry tools like your compressor. The inverter you have is just what I call Point Of Use inverters and true high end Off Grid Inverter like ones everyone else mentioned will handle that load just fine. A 4-6kw Magnum, Outback, Schneider, SMA and if budget is concern an Aims inverter will work but they are flakey now. The Aims Chinese knockoffs will work in pinch like GTPower. John
Hi John, I agree with you. Basically I am buying the components as I save up for them. I don't expect much from the cheap small inverter. I look forward to buying a larger, whole house inverter from one of the companies you mentioned. Since those are going to run into $4k, they will take a while to save up for. The cheap inverter allows me to start using the powerwall now, which I do. Back in my video about the Reliable inverter ruclips.net/video/me0eAJL95og/видео.html Which do you use, or recommend?
Little helper is learning a lot very cute video
Nice I have a smaller version Victron 100/20 Solar Charge Controller MPPT, works great. BTW I had no issues with the app on My Android Samsung S7 Edge. Thanks for the info. Keep the videos coming. Greetings from Spain ;)
Should have gone for a Victron inverter too! My 3000VA (2400W) peaks at 6000W.
Victron inverters (and many others) have pretty bad idle power consumption. The Australian Selectronics one is impressive
@@Wallabynge or Latronics, also from Straya......with impressive start-up current, even handles my house a/c. …9 years of continues use, never missed a beat.
Awsome job!...For more power wash those panels clean David!
Haha. Yeah, they had a lot of pollen on them.
Thank you for all your highly informational videos and non-complex way of explaining things!
Great! Look forward to seeing it running with all the panels.
As I tried to explain in a previous video, if you connect all the cells of the same level in parallel, then you'll only need 1 decent BMS, not 8!
Great video no solar around good info. Can't find solar output when cloudy. A huge value like and extra battery free!
Don’t look now but there is a Beautiful Woman on you number trying to pass you up. I heart that the Alt store had bad customer service. Love miss Amy’s Instructional Vids she has taught me a lot. Best of luck. P.S. get a BMS.
Hi Jim, To give you an example of why I like them: When I went to buy a disconnect/combiner box ( ruclips.net/video/IJluk4U8pys/видео.html ) I asked for a particular model box, and circuit breakers. Then one of the sales guys (Adam) came out from the back to talk to me. He recognized that the model box I asked for came with a combiner bus bar meant for 150V breakers, but I was asking for 300V breakers. After clarifying, he changed my request to a slightly different part number that came with the correct busbar. He saved me a return trip. I didn't know there were different part numbers for the parts inside the combiner box.
Make sure to update the firmware to the latest. There is a protective feature in the newer ones that you want.
Victron is good stuff. I played with the cheap stuff for so long.... Finally spent some change on a Victron and would never go back.
Aaron Anderson my farther has built 35 boats over 4 years with all victron gear including 3 165ah lithium batteries for a boat hire fleet

That kid is gonna learn so much.
Nice option for all the 12 solar panels. Also thinking in a future, never know when moving for an upgrade. Congrats!!!
Have you looked into doing an AC coupled system with those SMA Sunny Island?
More efficient because you would use the power from the solar panel directly most of the time through compatible grid tie inverter.
Yes, I bought a Sunny Boy and some used panels. I just have to build it. I look forward to testing the overall system efficiency with AC coupled.
@@DavidPozEnergy looking forward to that, thanks for your reply.
Have you looked at REC bms’s? I bought one for my nissan leaf battery. It can will replace your 712 meter and shunt, it also “speaks” over the Victron CAN bus and talk to a GX and I’m pretty sure it’s inverters.
No, I have not looked into REC.
DavidPoz ruclips.net/video/j8dWyNSwyqk/видео.html
That's a good video. I love that guys Nissan Leaf battery. The part that is intimidating to me, he is using a computer. I'm not a computer programmer.
You can setup a raspberry pi to allow you to control it over the web. very nice bit of kit
Hi do you know how to do it?
It means you can monitor from anywhere on earth as long as there is WiFi connection?
Thanks
Awesome video my friend and thanks for sharing
Would this system work on a smaller 12V LifePO4 battery system but will be upgrading to a larger 48V when more solar panels arrive. I don't want to purchase a separate charge controller - .... and I want one charger to work on the small system until more panels arrive and I connect additional batteries. It seems like this would work - but just want to check .
Hi David great vids
How you set-up bulk ,flot, absorption to your litium battery?
I'd like to use lifepo4 15s bank to charge it to 3.50v per cell what would be your advise to setting?
Much appreciated your reply
Thank you
Hi Pawel, I used the "User Defined" setting. This allows you to your own voltage. So if you want 3.5 volts per cell, times 15 cells, then your charge voltage is 52.5 volts. You can set this in the User Defined section. In this section there is only absorption and float. I turned off equalize. Set Absorption to what you want (52.5v in this case) and the float slightly lower. Maybe 52.0v. Last, turn off "temp. compensation" which could over-charge the battery if the charge controller senses low temp.
Thank you much appreciated

Great I'll take a look
I'm having issues to set equalisation to zero or to disable I've looked everywhere on manual, I'm thinking if the victron 100/20 48v I have is not faulty
Would you suggest to check for current firmware etc
Thank you
Your explanations are helpful. Thanks
Ok. Just finished the video. Thank you for checking the voltage
Victron Bluetooth only seems to work with half the phones you throw at it. I tried 3 Huaweis (no dice). Works with Samsung A5, Tab 4 and ZTE A520. It's going to be a major problem 7 years down the line, when you find nothing works. One thing that worries me is that amateur installers will not worry about configuring 200V panel arrays. This DC voltage will sustain a 33mm welding arc, which can burn your house down. Must say I'm mystified what those 2 panels could be, that yield 623W. My panel yields can be about 75% of rated value, due to heat and wiring losses.
Those panels are LG365N2W-G4. Thanks for watching.
85% yield with -0.38% loss per °C in what looked like cool weather, with a tarp just pulled off it. Thanks.
How much 12v battery u can use to bill a battery bank
What a monster lots of juice there
Hi David, Thanks for your videos. I am looking at your videos and of others, and websites of victron midnite and magnum energy etc, and I can't seem to find a charge controller that does both wind and solar. I am a complete newbie at this, and I am trying to plan for an off-grid cabin that will be up in a couple of years. Thank you to you and your fans for this community.
To my knowledge, there is no charge controller that will do both solar and wind at the same time. You will need two charge controllers, one for solar, and one for wind. I don't own wind turbines, so I'm not a good resource for information. But, I think I have seen Midnite Solar charge controllers used with wind. Or, sometimes you order the wind turbine and it comes with a charge controller in the kit.
@@DavidPozEnergy Thank you good sir.
Hi, Cool video. I am planning to build a solar panel facility of app. 12kW
using Victron products as “brain parts” as you show. The challenge for me is
following: I will use 4 x 5,3 kW Tesla Model S 24v batteries serial connected
to 2 x 48v as hybrid power bank. Also use the 20/80 % load rule of the battery
and apply to max 50v and 37 v as cut-off values. In Denmark we use 220v 😉. I am unclear witch Victron products I must buy in order to build a on grid
system able to handle the Tesla batteries? Can you help me?
Not all Bluetooth implementations are equal. My wife's fitbit has trouble with both Samsung and Huawei. The Victronconnect app works fine on an ancient note2 and on my new Huawei but fails on the s4 mini. That's to say, it might be a combination of the phone and the older firmware on the Bluetooth interface. These controllers always ship with slightly older firmware. You are expected to update them at install time.
HI David, I did comment on one of your other videos, You do not need 8 BMS's you only need one, I stated in the last one that you can look into the Batrium range of bms's they upgradable, that means that you can get the watchmon controller and as many longmons as you have cells that need managment, please contact batrium for assistance they are SUPER helpful and VERY knowlagable...... I just can't state enough that you need a bms for lithium.... Regards Charles.
I believe the app can not show graphs of voltage and current (the daily bar graphs are too coarse). Pity. Is anyone aware of a charge controller that does?
So what about 48v 3 phase off grid system?
Best DIY babysitter ever
I really like your videos and how you explain everything you're doing and what items you're using. I subscribed
Thanks for the comment.
The Volt Batt are liquid cooled, if you draw too much or you fast charge it will they get hot without coolant ?
You are right, if I was to move too many amps too quickly in or out of the batteries they could overheat. The good news is that running a tool and AC in my garage is nothing compared to moving a car down the highway. I'm not pushing these batteries at all.
You need Low Frequency inverters if you want to start a motor, or something with a motor in it eg: compressor or AC unit.
They use proper transformers in them unlike the high frequency inverters which just use electronic trickery to barely run at their rated power, if at all.
What’s wattage of those panels?
Can you hook up a generator to it ?
While you don't have much use for all of that enery stored in the batteries you should limit your charging voltage to 4v per cell. Being high state of charge for a long time does increase internal resistance of the cell
Do you have a schematic for your solar plan and a parts list of what you used. Disconnects and breakers also.
Love your clear explanations and videos. I have 2 separate Victron 5 KW 48 volt inverters, connecting to 2 separate locations with breaker boxes, 110 volts each. and total of 16 deep cycle batteries. Can I connect both inverters to same battery bank using a large bus bar? Thanks so much.
heya the victron charge controleres are great
Is it possible to control how much energy is transferred to the grid? I guess there is a fixed output of 300 W, 600 W or whatever. But is there any chance to control it?
those are massive panels, where they from what is the W#
LG panels, 365w rated. I bought them used from Craigslist, they were taken off a commercial project. Thanks for watching.
looking good man! thanks for the update.
for power tools I would go 6000w, 3000w is just to small for almost any power tool with a large startup load. anyways love the video, be careful overloading the inverter that long after its warm they have a much higher chance of blowing.
Thanks Going Off Grid. OK, I will certainly heed your warning about the inverters. I haven't seen anyone else with your experience with this "Reliable" brand.
also try using a 50' extension cord this will allow the voltage to drop and the inverter may start the load, I have done this many times and it works a lot of the time, and you can open the inverter and turn the voltage to 126 volt this will allow more power as well,
Bear in mind that Victron states that their inverters are able to handle peak power requirements of almost double their running max
D G Roberts, Yep, they do claim that. I wish they stated how many seconds that surge is for. With Magnum, Schneider, and Outback they will tell you in the spec sheet. Victron just says "Peak Power" with no time.
Well my trail and error testing was running a small fridge. The startup power required is 725w. My original Victron inverter was 300w max. It failed 9 out of 10 times. I upgraded to a 500w inverter from Victron and it has not failed on over 2 months of use. The 500w is rated to 900w peak. Now I was fortunate to have a friend in town who supplies these and could just exchange for the larger inverter (paying the $ difference of course)
I encourage you to to look at bobolinksolar.com

10:01 Are all the holes on the face-plate for venting/screws? I am wondering if the circular ones might be connected to each cell to check voltage/screw connection during initial install. Not really sure if that made sense...
Looks like a great system. I am big into upcycling and repurposing things as well as solar in general. Glad I found your channel.
Hi Dakota, I not sure which holes you are referring to, but here goes... The battery shelves are made of slotted steel angle. That is made with holes and slots to allow different bolting options. Or, if you are referring to the 5 large holes in the bottom of the cabinet, then those are to allow venting when I install Plexiglas on the front. I hope one of those helped. Thanks for watching.

whats the limit conexion of modules i can do with this 5800W regulator ?
5 serie and 3 parallel? if the power of each module FV es 370W

this is correct?
thank you for the vidio. Greetings from Argentina
Good job .

Thanks.
do you need a Battery Management System if batteries are not lead acid?
Most sites I've read say a BMS is very important with lithium batteries, however there are some RUclipsr's I've seen without them. I suggest them to err on the safe side.
Mein Abo hast du 🤗👍weiter so
Curious why you said you can only run 4 panels in series. It is 250 volt, so your typical 12v panel should be able to run 6+ panels right? I thought I read somewhere in the online manual that you could run 10 in series and if it got too cold you just lost some efficiency. Am I wrong?
My panels have Voc=47.7v But if your particular panels are lower, then you can run more in series. I hope that clears it up, sorry about that.
hi david what was your bms for the volt setup ? ?
If I were building the battery today, I would buy these: batteryhookup.com/products/li-ion-lifepo4-3s-20s-30a-bms-with-balance?variant=42283333910690
They are affordable, and good quality. The Chevy Volt battery breaks down into 8 individual batteries, each with 12 cells in series. So, I'd buy 8 of the BMSs, remember to select "12s li-ion". These BMSs are limited to 30A, which means 240A for the whole pack. If you need more current for your inverter, then Battery Hookup has a 100A version as well: batteryhookup.com/products/12v-lifepo4-smart-bms-w-low-temp-cutoff?variant=36287975391394

Great video. ...on my magnum inverter I can run my mig tig and stick welder no problem but I don't no if I can use the ion batterys with it....great video thanks again
That's great. I hope to learn how to weld tig some day.
If you are connecting your PV panels in series, then you will get the same amperage no matter how many (assuming they are the same). So you can use the same cable for 2 or 12. This is the main advantage of higher voltage configurations (in series) vs high amperage (in parallel).
Hi Jarek, Thanks for watching. As for my comment about only two panels to keep the amps lower, I was reffering to the battery side. The MPPT charge controller drops the volts down, and increases the amps. I was using a piece of 12 AWG wire.
Hi, i have 4 solar panels for a total of 400W, same specs (21V 5,65A shortcircuit), but i've noticed something strange, if i connect in series (2 couple of parallel and in series, 42V 10A) or all 4 in parallel (21V 20A) i only have a total of 240W, the problem is not the cable because i try to shortcircuit in the back of panels or near the charger, same results.
The weird thing is that se single output panel when i shortcitcuit is 5A, but when i put all togheter i have only 3,8A, same thing with real MPPT or cheap PWM.
Thank you very much if someone know how to help me :)
Yes, a quality tablet is usually expensive, but there are many low-performance simple tablets out there. The screen won’t be gorilla glass. They tend to break if dropped or abused, but for the very basic functions like email, internet browsing, simple audio and video - they are okay.
I have that controller. Its awesome!!!!
I see this is purely off-grid. Can I use it for grid-tied systems too?
There are a few inverters on the market that allow for off grid, and back feeding at the same time. Sol-Ark is the big one that comes to mind. But, for me, I'm happy using all my solar off grid, and just using the grid as a back up to my system in case I don't produce enough solar. This means I don't back feed, but I can draw from the grid when needed.
thanks for the video, very informative. I have a question though do you need breakers to connect from the battery to the controller? I just bought a PWM 60 amps charging system which I connected to four 100w solar panels, should I add breakers and if I should which type of breakers? thanks
Hi Otis, Thanks for watching the video. Circuit breakers serve two functions. First, they add a level of safety so if something shorts out, or is overloaded, it trips. Second, it gives you a means of disconnect so it is easier to service part of your system without shutting down everything. I think it is worth it to install them.
I buy mine from www.altestore.com I'm not affiliated with them, it's just where I buy my stuff. If you call they can match you up with a circuit breaker properly sized for your solar voltage and amperage, as well as your battery. The breakers I have are made by "Midnite Solar" and are DC rated. As an example, here is the breaker I have between the solar and charge controller in the video, however this is not necessarily right for your application. www.altestore.com/store/enclosures-electrical-safety/overcurrent-devices-fuses-breakers/din-rail-circuit-breakers/din-rail-mount-circuit-breakers-p40906/#GENBRKDIN-15
Thank you. I am at the learning stage. I have purchased some panels. I will probably pick up that brand of controller too. Would you recommend the Volt Battery over the Tesla Battery packs? I seem to have easy access to the Tesla batteries at $1,250 each.
Hi Bill, I'm glad the video can help you with your setup. I do not recommend Volt over Tesla, or the other way around, they can both work great.
I have not used the tesla batteries myself, but from what I can see they are very easy to wire up. I had to modify the wiring in the Chevy Volt pack (check out the video) but with the Tesla I think they are good to go from the start. So that is nice. But, the Teslas are a bit more expensive.
Really enjoying your videos. :-) I am running the Victron 150/70 controller with 1800W of solar to a 24V Li-Ion battery bank from an EV. I am curious what settings you are using for absorption and bulk. Since I am running 6S, I just set them both to 24.6 (4.1V per cell) and feel this could be better optimized. Thanks!
Hi Doug M, Right now I'm not cycling my batteries very much, so I am using 4.0 volts per cell x 12 cell or 48.0 volts in absorption. Then I'm running float at 47.7. This was recommended by "The Hillside Pranburi" and made sense to keep the charge controller from short cycling between the two modes.
That makes sense. Thanks again for the great content!
@@dougm4154 You don't float Li-ion batteries. It's bad for them. Floating should be disabled (not sure if this is possible).
Sorry for my ignorance... MPPT, BMS ?
Sorry, I should have clarified in the video. MPPT stands for "Maximum Power Point Tracking". This allows me to use a high voltage solar array ( up to 250 volts) to charge a low voltage (48 volt) battery. Not all charge controllers have this ability to drop the voltage down. Some charge controllers are called PWM (Pulse Width Modulation) and for them you need to match the solar array voltage to the battery voltage.
BMS stands for "Battery Management System" which is an important safety device when using lithium batteries. I have lithium batteries and should install a BMS. The BMS can monitor and balance each cell in the battery.
I'm actually just learning about BMS's myself so I'm not a great resource to learn about them.
Thanks for the clarification ! Love your videos keep then coming :-)
Good stuff
Does it still work? 5 yrs old now.
Yes it does.
If you have a 12S Li-ion battery system, shouldn't the charging voltage be 50.4V since each cell is 4.2 and 12 in series is 50.4V? Is there a way to set the charge controller to this exact voltage?
Hi redstone craft guy, You are right. 4.2 volts per cell is the maximum voltage per cell for this type of battery. The Victron charge controller can be set to exactly 50.4 and does an excellent job stopping there. I'm keeping my voltage a little lower at the moment because I have not yet installed a BMS. A BMS is "Battery Management System" and offers safety when maxing out the charging. Thanks for watching.
@@DavidPozEnergy ok thanks.
@@DavidPozEnergy If you don't need the extra 20% capacity, keep it at 4.00v per cell you will get about 4x the cycle life at that voltage compared to 4.20v charging.
What size circuit breaker did you use ?
I forget what I used in this video, it was just testing. But, when I hooked it up to my main house battery I used 125A circuit breaker and 1/0 wire. Thanks for watching.
Android apps always have issues especially on different models of phones are not on the same version operating system.
What is the max size wire that will fit on the MPPT, the lugs look too small for 100 amps
I think it was 35mm wire, I can fit 1/0 wire. I have another video where I connect bigger wires: ruclips.net/video/QhUoS6T75N0/видео.html
Fantastic, WOW, Yee Haw 100 points Mr Magoo in Milo, Maine Thanks for sharing.
You got it wrong homie. You can connect as many solar panels in series as you want without it affecting then amperage. Voltage stacks in series, amperage stacks in parallel. So whatever wire you are using for 2 panels , you could use for 100. This is exactly why power companies use 500KV lines for distribution. It allows them to keep the wires skinny and not waste so much energy heating transmission lines.
Hi UltraStoat, Thanks for watching. I'm sorry if I wasn't clear in the video, please allow me to explain what I meant. The wire from PV to controller is fine, you are right there. However, I meant the wire from controller to batteries was too small. My solar panels are 365 watts each. If I had strong 4 together, that's 1,460 watts. The MPPT charge controller would drop the voltage down to 48 volts, making the amps to the batteries 30.4a. (1,460/48) 30.4 Amps continuous is too much for the 12 AWG wire I used (that yellow romex wire). That was my limiting factor.
Hi DavidPoz, so one thing that I read when I was looking into Victron charge controllers was that you couldn't install them on heat conductive "substrate." What did you end up mounting it to? I am trying to determine if the device gets too hot, and could catch whatever it is mounted to on fire.
I had mine mounted on plywood for 2 years until someone pointed out to me the requirement. So I added a piece of thin aluminum (white aluminum flashing) between the charge controller and plywood.
@@DavidPozEnergy Thanks for the info! I wasn't sure what would work. Sounds like you haven't had any issues with the aluminum flashing.
What the manufacturer wants is for you to install on a fire-proof substrate. Steel, aluminum, bricks, concrete, are all fine.
Looks good. keep em coming
👍👍
Check out Batrium if you haven't already for BMS possibilities. Expensive but just... so full featured.
Or, slap some Chinese BMS boards on there and call it good.
Hey David, since it has been almost a year since you put in the Victron, What is your opinion of it? have you have any problems and have you had to call tech support? I hear that Victron is great, but sucks if you have to call customer support. I am looking at buying Victron.
In the very beginning I could not get the charge controller to talk with the battery monitor. They are supposed to. Victron did get back to me (e-mail) but just told me to contact my supplier. Luckily, I had purchased it through Alt-E. Alt-E has amazing customer support. I spoke with Alt-E about the problem, then they went to investigate, called me back a couple hours later with a solution. Perfect. No problems since. I am not affiliated with Alt-E, just a happy customer.
For your compressor maybe you should try and AC capacitor in line, wth What they use on a microwave or something bigger electric motors

I have the victron demo app, and I cannot see where you can change what type of battery. Do you know if you could charge nickel metal hydride batteries?
Hi DIY Dan,
There is not a pre-programmed option called nickel metal hydride. However, there is also not a pre-programed for lithium 12s, which is what I'm using. What I did was select "User Defined" and input my own parameters. I set mine to limit the voltage to 48.6 volts, which is 4.05 volts per cell in my setup. At first the charge controller would go a little over this, until someone told me about the "temperature compensation" built into it. It's on the same settings screen for the battery, just lower. I turned the temperature compensation off. If you know the charging voltage for your Nickle metal hydride battery you can also program that it.
I hope that helps.
The settings is the logo that looks like a gear in the upper right corner. Then select battery.
I came across NIMH battery packs at no cost, want to give them a try thanks.
Just out of curiosity does that Victron energy charge controller still work???or was it a waste of money????
Still working perfect.
DavidPoz So you are very pleased with it and would recommend one???
Yes. This is an affiliate link to the exact model I have: amzn.to/2YK6eJM It has been working very well and I would recommend. If you don't need 100 amps, then you can save money with a smaller amp model.
DavidPoz is Amy still there?I know she was very knowledgeable,,, did you buy this from ALT e solar or Amazon?
Hey : Love your content keep it up :) Quick question for you, I have some 40V batteries that are BAE 200. Would this Charge controller be able to handle it? Can you set a defined max voltage on them or do you have to choose from 12v 24v 36v 48v? Thank you very much!
Hi Maxime, On my app I can set a maximum charging voltage, it will not go over that. I showed the range in the video, which is 39.00v up to 69.56. I can actually go lower if you select 12/24/36 volts instead of 48 volts, but I'm using it at 48 volts. I don't know the details about your battery, but if you want to set a maximum charging voltage of 40.00 volts, then YES, it can do that.
DavidPoz And can you also set minimum discharge voltage? If so this is the charge controller that I need :) Thanks again!
No, you can't set a minimum discharge voltage on the charge controller. This is because when you are drawing off from the battery you are not drawing through the charge controller. However, some inverters can be programmed to the minimum voltage before shutting down.
Where did you get those pants?
I bought them at a trade show, JLC Live. It's hosted in Rhode Island every spring.
@@DavidPozEnergy Can I trouble you for the brand name of them?
Sure, They are called "Blaklader Workwear" but there are some dots over the As.
@@DavidPozEnergy Found them, they even have a Canadian web site, thanks.
Appreciate your videos, very accurate, i am also building a volt battery setup and i’m gonna use a victron mppt controller, if you don’t mind telling me what charging parameters did u use on your setup
No problem at all. Good luck with your build. My batteries are arranged 12s, or 12 cells in series. I'm choosing to limit my charging to 4.1 volts per cell. So multiply 12x4.1=49.2 volts. Inside the app, I select "User Defined" then I set the Absorption voltage to 49.2v. Next I set my Float voltage to 48.9v. I set this 0.3 volts lower to prevent the short cycling from loads pulling down the voltage temporarily. This is just what I do, but some people like to adjust slightly one way or the other. The main safety thing is that the cells should never go over 4.2 volts per cell or risk damage/fire. I hope that helps. Thanks for watching.
For Android phone to work with victron app turn GPS on
Hi akram hawere, Thanks for the suggestion. I had tried that, along with several other suggestions I found on blogs. Nothing worked until I updated the firmware. Now the charge controller will connect to my android even with GPS off.
How did you connect solar parallel or series?
In this video it was two panels in series. I'm currently working on my big array with 12 panels. That will be both series and parallel. That video should be out in the next few days.
