As always, mount these inverters to a non-combustible surface, such as hardiboard. It costs $10 and will increase your peace of mind. Also, avoid combustible materials within a 4-foot radius. Check out this video where I show how to do this: ruclips.net/video/01qYerhorwU/видео.html The unit was not charging because I forgot what model I was working with. It requires 120VDC minimum at the input to work. And it has a max input voltage of 250V. I don't know how I messed that up. I was just using the 148VDC max model the day before, so mixed it up. Also, use the proper terminal ring hole size for your inverter. I use these on multiple inverters, so they are huge. 48V System Parts List (Affiliate Links): Pro Version 48V LiFePO4 Battery (now in stock!!): www.signaturesolar.us/products/48v-100ah-lcd-battery-by-eg4?ref=cPwLcVc0SW-BjN Budget 48V LiFePO4 Battery (preorder): shop.signaturesolar.us/products/48v-100ah-lifepower4-battery-by-eg4?ref=cPwLcVc0SW-BjN Battery Cables: amzn.to/3zbM6Bd 48V Growatt All in one System: www.signaturesolar.com/products/3kw-48w-150vac-80a-off-grid-inverter-by-growatt?ref=cPwLcVc0SW-BjN 12 gauge extension cable: amzn.to/3jxNxmO Solar Panels: www.mobile-solarpower.com/solar-panels.html TClass Fuse: amzn.to/3FKtv1p Solar Disconnect: amzn.to/3JvpqAn Combiner Box: amzn.to/3FLL55o Solar Panel Array Voltage Calculator: www.solarchargecontrollercalculator.com/ How to design a solar array wiring configuration: ruclips.net/video/C-k0WHJ4RxQ/видео.html *Does off-grid solar confuse you?* Check out my DIY friendly website for solar system packages and product recommendations, and so much more! www.mobile-solarpower.com *Join our DIY solar community* #1 largest solar forum on the internet for beginners and professionals alike: www.diysolarforum.com *Check out my Book* Best-selling and beginner-friendly guide to 12V off-grid solar! amzn.to/2Aj4dX4 If DIY is not for you, but you love solar and need an offgrid system, check out Tesla Energy!

Will I received my Jakiper 48v Battery (with a bent handle) and my Growatt 48v charger, and would like to know what size cables you used for the battery...
@@ricardocastaneda8276 0 gauge is overkill and works great. Each manual will recommend a different size though. Some are ok with 2 or even 4 gauge, but you need to check the manual.
We have 2 5k Growatts w 4 of the EG4 batteries (budget version). I would love to see this system with the transformer. Thank you so much for this video!!
Retired elevator man here. When working on live circuits. Keep one hand in your back pocket. Less chance of going thru your heart. When engaging a disconnect turn your face away from the switch. When it goes south they explode like a bomb.
@@davelaseer1344 Back in the 1970 and 80's elevator machine rooms were not air conditioned. Pre computerized age, that 140 degree sweat box was all summer long. So you were dripping wet and always working on live circuits between 48VDC to 240VDC and 24VAC to 440VAC. In tight places sometimes wore latex gloves to try and keep from getting a jolt. WE used insulated floor mats around controllers. Just assess the environment and mitigate the chance of getting shocked or hurt. Made it 40 years without a single serious accident for my workers under me or myself.
@@demolitionkid2 still turn your head away. I have first hand experience with a couple of 440VAC disconnects exploding when turning on and off. 40 years working on many live controllers, motors, generators and inverters made me very cautious. Kill power whenever you can and use all the PPE and hazard prevention available.
Coming from someone that has gone to school for Hybrid vehicles and high voltage systems, always assume there is voltage at the terminals until you check them with a multimeter! (You should always check with a multimeter!) never assume a high voltage switch is operating properly until you verify it!
well if you really want to get technical about it you should do a "live dead live check" (NEC 110.4) . check meter on live circuit to confirm its working typical and outlet or dedicated tester, test the circuit you are interested in working on, then test on a live circuit again to make sure the meter didn't die when you tested your circuit of interest and is just showing no voltage. sounds like overkill personally I only ever did it when doing 480Vac+ stuff
@@orbitONhigh In this case i would just switch the switch to on and measure and then off again and one should know enough if the meter is working , if both states dont show anything then the meter is broken or the source you trying to measure is a case of a problem
@T.J. Kong Yes, they have a service disconnect which cuts the battery in half. There is also a fireman’s loop where then can easily cut the cable to quickly disable the system.
Just like shooting guns. Always assume it’s loaded and live before pointing it. Verify the safety first. Would have been a good rule for Alec Baldwin to follow.
Hi, Will! We are older folks who have interest in this kind of thing, but are rank beginners! It is always a pleasure to watch your videos...you do an excellent job explaining things to us folks just starting out! Keep up the Great Job! God Bless!
I’d have to say at 54, I have a good understanding of electrical properties but a bad understanding of “best safety practices”. These videos help enforce things we may overlook.
@@tblbaby Yup, I'm your age and am usually paranoid enough to be safe. But Will point about voltage through the heart rang clear for me. I was a career Law Enforcement Park Ranger, in Utah, I was assisting an elderly person change their flat tire. A dark set of clouds came over the mountain, lightning hit the ground about a quarter mile away from me, however I was holding the tie rod in both hands, and a huge electrical current went through my chest cavity. Never thought I could be a human lightening rod. Took a couple of hours from the chest pain to subside. (Didn't get any super powers either:( ).
@@SuperJamster1 YeeOuch! My dad was holding on to a fence and lightning struck it far away, knocked him on his ass. I stepped out of a puddle in the rain just before lightning sent a jolt through a cable on a power pole and into the puddle. I've been shocked many times. 220 dryer, 100 cycle jet engine test cell short through my head lol. Fell off a tree into a full ditch head first having my legs tangle up in electrified barbed wire and having to rip my pants off it to get out as it was jolting the hell outa me. Fun stuff like that. Never got the lightning through me though, thankfully :))
@@tblbaby Ha ha I love those stories. I've had my share too, including electrical fences. But my favorite is when I was working on wiring some 12 gauge in my barn and my wife decided to throw the outdoors panel breaker (old tube fuses) back on. Guess she wanted to see if my life insurance was up to date.
As a newbie, I have never commented on anybody’s videos. Until now. The value that you offer is among the highest I’ve ever seen. Your degree of clarity, matched with your passion, is outstanding. As a general comment, keep it up. We all very much appreciate it.
Well this is funny timing. But so thankful. We’ve put half of our 10 kw Growatt system. And been using it, a month. We bought the other array and got it installed last weekend. Today, my husband will tie that array in. We’ve gotten 2 of the 6 batteries in. As soon as my husband gets out of bed this morning he’s going to watch this. I’ve been worried about tying all the components together, but Wonderful Will has been helpful all the way. Thank you!
Thank you for the safety tips. When I was a young guy still in elementary school 4th grade. I was outside flying my kite one day in Irving Texas. Somehow my kite got stuck on top of the school house building. Only way I could see to get up there without a ladder as I was quite the climber young and agile. Not so much at age 62. Anyway I saw a place I could put my hands in to climb up. Me a ignorant fourth grader I put my hands inside this somewhat small box to pull myself up further to potentially climb on top of the roof. I quickly found that it was an electrical meter without the face cover on it. Needless to say I got hit with some serious electricity. Which caused my hands and muscles to immediately clinch I felt the current very strongly all the way up to my shoulders. As my feet were on the aluminum sided building fortunately I had enough leverage to break free and fall on my back. I can't recall even thinking about this event since that day and some weeks after. For some reason you're very intelligent teaching brought it to memory. Thank God I had my tennis shoes on if I hadn't I wouldn't be here today. We used to run around in bare feet quite often in the hot Summers of Texas. Over the period of my life I've had many close calls with death which I'm not going to bore you with now. Clearly our creator has plans. I'm in the process of building a 48 volt system with a battery Bank of 48vx304ah. For my box van RV conversion.
Thanks for going over the simplicity of the set up. I will be looking for the video where you build a bigger system with more batteries and can show the proper set up of the bus bars and those t fuses. Thanks for the reliable information Will!
I’m a Union electrician in NYC. 35 years experience in ALL phases of electrical work. 48V is the line of delineation between “high” voltage and “low voltage. It also separates electricians from data technicians mostly because back in the day most telephone circuits ran on 48V systems. And to be honest 48V kinda tingles a bit of you get hit by it. You would never want to be holding it when the phone rings. That closes the circuit and that’s when it hit’s you. It’s a long running joke amongst veteran electricians. I would love to help you out when you decide to start enclosing your wiring in some conduit. Good job Will ✊🏿
I like the simplicity of teaching here. Another thing to consider is if the person is still leery working with the voltage on the solar panels, they could wait until it's night so the voltage and amperage of the panels is at its lowest.
Man - I dont personally have a solar system - yet. But the enthusiasm that Will shows during his videos is great. Dude genuinely loves doing what he does and it shows.
I suggest a cheap lock out tag on breaker. Even a piece of tape over breaker reminding you to double check before removing tape. Even a quick check list before you remove tape.
I know when I see the 'plywood blank canvas' up, I'm in for a Will-full edu-ma-cation fer sure! Thanks and gratitude for all your enthusiasm, open-source info and holding these manufacturers to account for shortcuts and shortcomings. You da man Will!
I built an off-grid solar battery (after the great Texas Freeze last year), have 6x100W panels and a 300amp/h battery connected. Spent about 3K total on the project and super happy that it can take anything I throw at it. Not a 1-1 grid replacement but definitely piece of mind.
“if you get enough current to flow through your heart you are instantly dead 😶… but that’s the only downside! 😄” something about his delivery on that line cracks me up
You do a great job explaining very complex and dangerous equipment. I appreciate the way you emphasize safety and explain how o.1 amps of current can kill you. Thanks for making this so easy to understand.
Been shocked many times by 240v, only kicked like a mule and my heart is still functioning. This same thing has happened to manyy electricians I know and they are still alive.
The thing about wiring a panel is that the knowledge base for a panel is like a 5gal pail whereas installing this small AIO setup the knowledge needed is akin to 16oz bottle. You can safely install the AIO with step-by-step instructions but a panel has so many variables and alternative paths in the flowchart. One video probably can’t tell you everything you need to know.
@@fishhuntadventure no doubt, thats why i said if possible. At least some basics as the extension cord doesnt help to run a whole house which is what im planning. Im sure its complicated and has liability along with it, but its also necessary and valuable info.
My dad mentioned you could connect your final solar array MC4 at night. Then you wont have any power... The other thing I was going to suggest is adding red tape to your MC4 adapters so that you don't get it wrong. Thanks Will, great videos. Super helpful for sure.
Will! You're amazing. I have a similar history as you, with the medical issues and surviving in an RV without family help. Doctors have been no help, so I started reading medical journals and dictionaries to figure it out for myself. After years of struggling, now I'm healthier and have my RV gutted, about to buy a 48v hybrid system and a mini split to install. Thanks for putting your inspiration out there for us. :) I'm glad you're getting along better now.
You know, when I first found your channel everything was so damn daunting. Felt like the first time I build my computer all over again, after some months though, the hardest part is saving up for all the parts in one go.
Thank so much Will, your videos helped me put a 300 watt solar system on my teardrop trailer for of grid camping. now it’s time to add a 48 volt solar system to my house. You have given me confidences to try it on my own.
A lot of times I don't ever plan on building some of the things you have videos for BUT I still watch them because I ALWAYS learn something new. And also your presentation is awesome! Thanks Will...
Great and needed video, Will. Solar is a great hobby but high voltages will kill you. These all in one systems are very safe if you are careful. I am an electrical engineer and Will’s practices in this video are rock solid.
Brilliant! These instructional videos are invaluable as they save many lives in addition to educating millions. Teachers like you do great public service and I hold you in high regard. You are like the Khan academy for this domain.
1:38 "only negative is that 48v will kill you". "If the current flows, you are instantly dead" (will prowse laughs) 😂. Thank you for the wonderful simplified tutorial
I'm an old guy that has actually learned much from you regarding PV panels and storage batteries and has built a small 12 volt back up system for tornado season here in Kentucky using info I got from your channel.. My wife and I both are grateful for your channel for that reason. A really silly thing that I would like to ask you, that has zero to do with solar or batteries is, where did you grow up? The reason I ask is because the way you pronounce words like "tighten" is much more "precise" that anyone here in Kentucky would pronounce them. It may not be a regional thing, because you seem to be very well educated and may just say things "right" for that reason, but I'd really like to know, if you don't mind sharing. One of my "things" that I tend to pursue when I meet new people.
I finally got my system built and operational in October. I studied for 3 years, buying panels and watching you and David Poz. I made my own adjustable array with a combination of sixteen 350W and eight 315w panels, 2 strings of 12 each. Went with two 48v banks of Rolls S6 L16 FLA batteries @ 445AH for a total of 890AH. Went straight to the top and got a Sol-Ark 12K. Added a Winco propane 8K standby generator. Love the SOl-Ark. It's not "set-it-and-forget-it", but it's ability to direct the greatest input to the most needed output is outstanding. The auto start feature for the genset is just fabulous. The videos are unlisted, but if you should have any interest in seeing the build, I'll send you the links! Learned a LOT about FLA's. Properly maintained, You can get better than 10 years out of them. Believe me, I did some thorough researching before choosing FLA. They match my personal parameters for output, maintenance, cost and life expectancy!
I had backwoods solar design a system for me and so far I have my solar panels mounted with a 1000 gallon propane tank and a 12k Cummins generator behind the panels. We’re running 180’ to the house after combining two 4 panel sets. The panels are 385 watts each and they’re 48 volt panels. We just got the upstairs closed in but now we need to pull wires and wire the house and we’re going into the deep freeze for a while like -10-20 below zero at night. I can’t wait to have it all hooked up! We will be supplying energy for a SIP house that’s 28x32 on a walkout basement. Heat will be supplied by a propane fired by a modulating boiler hooked up to infloor heat in the basement and baseboard upstairs and wood stove will supplement the upstairs so hopefully that thermostat won’t ever call for heat.
Your youtube content is interesting. I like your old school approach (I am old school as well). I am interested in the info you have for your solar installation, if you're still offering... Thanks in advance.
solark might be great but so are the price 6900. plus batteries plus panels . wills system showed 1500 t0 1800 battery 800 for all in 1 and 1000 panels 3600 total. yes smaller system but many off grid its plenty bigger systems are different and your inverters possibly the best
@@baby_UFO Their literature is the most thorough I found, and the tech support supplied quite an education. I noticed my specific gravity was never coming all the way up. Since I programmed 890Ah, the controller drops to float voltage when it sees current drop to 17.6 amps to the batteries. They were not sufficiently charged to bring the specific gravity back to specs. Rolls rep had me reset the AH rating to 800. This caused the controller to drop back to float voltage at 16 amps instead of 17.6. That translated to more hours of charging at 60 volts. The other issue I had was the Sol-Ark shut off the generator when it hit the float voltage of 54.7. On solar, the output to the batteries is 61.4 volts, with amperage determined by battery resistance. (charge) The bulk and absorption voltage is set at 60, but temperature compensated for 45 degrees F, hence the 61.4v. On the generator, the output is limited to 4400 watts i.e. 80 amps and the voltage remains lower than float. As they charge, resistance increase and the voltage rises until it hits 54.7v. It appears that Sol-Ark has programmed their system to determine float by reading amps while on solar, but using float voltage setting to turn off the generator. Since it has been cloudy for a month or more, I reprogrammed the float voltage to 61v to prevent the generator from shutting down at 54.7 volts. Yesterday was the first time since October that my specific gravity came all the way up to 1260+. Checking specific gravity is an absolute must to determine the charge of a FLA battery.
I did all the HEV and BEV diagnostics for Ford from 2010MY through 2016MY. Nominal pack voltage was about 320VDC if I remember right. Anyway, I always used an old trick of Nikola Tesla's, regardless of whether the service plug was pulled or not. When working with HV conductors, keep one hand in your pocket.
Just starting the learning process. We’re living in the tropics and for the start… run an AC unit and Fridge. No need to cover much else. Cooking is gas. I like the idea of 48v. Definitely not 12v but maybe 24v. Want to be able to expand for full off grid. AC worst case is 24hr. The plan is to tip the panels at 3 periods of the day. Friend of mine does that. Amazing how much difference it makes. He ran a well pump to show the difference… wow
I used Will's suggestions to build a solar system for an off-grid property. Dude knows his stuff. Will, could you do a guide on an off-grid battery set-up for cold climates (not in a heated house or anything)? Thank you again!
I have to say I've been a bit intimidated by figuring out how to setup like 3 x 100ah batteries, all the shunts, fuses, etc when I go to set up everything for my cargo trailer conversion but what you just showed me in this video has turned me to 48v setup just like this and not deal with 12 volt. I just would need to get a 48 v to 12v step down to power puck lights etc. If you could show us how to connect a dc to dc step down in a setup like this it would make my life SOOOO much easier. I was going to spend so much money on Victron stuff but I think that Growatt would be perfect for me and a server rack battery. Way less wires and stress! THANK YOU for the video sir!
The fact that it's getting easier to assemble these systems is great. The one thing I need more guidance on how to size the system I need based on usage. For example, I'd like to start with an off-grid system that powers my refrigerator in the garage. Then later, power my outdoor power tool battery chargers, then ultimately, charge my Tesla.
I would get a Kill-A-Watt meter. Plug it in-line with your fridge. It will read your electrical load. Find out, over the course of a month, your average KWhr load of the fridge. Mine drew about 2kwhr a day. The next thing is to figure out how much solar you need to generate 2 kwhr. If there is no shading, in the tropics you get about 3-4 times nameplate wattage in energy. So we had a small 660 watt system on a boat and had the equivalent of about 3.5 hours of full production, so about 2310 watt hours or 2.3 kwhr. That would run a fridge, in good conditions, but obviously if it’s cloudy or rainy, we would make less than half that. So either you would want to upsize solar or battery capacity to get through those days. In the northern climes, you may only get 2 equivalent of 2 hours peak production, or maybe 1.3 kwhrs. So it depends on where you live and where the panels are mounted. Snow. Shading, ect. My recommendation, mount as many as practicable, and then figure out what you can run. Because if you mount 4, your going to be thinking about 4 more within a year with expanded use. Cheers
Thank You! I have recently bought a Growatt as well. I have no knowledge of electricity at all, but I managed to connect an Axpert inverter 2kv. Using two 12v connected in series. The Axpert died on me recently! So I bought this Growatt! But all of a sudden I am fearful to connect this! First is that I may damage the unit, secondly its death ... I am currently connected using one of those boat inverters! This one does not scare me at all!
Lol! why would we criticize such a beautiful works sir? No need but only to appreciate your effort. Your explanation is amazing. i am an electronic trainer by profession but you are the best. Keep it up. I follow and watch your videos ever since I knew you.
Read my mind with this one! Loving what seems like an increase of videos from you lately. Some would say that you could of watched the 24v video but you supplied so much more information that a beginner like me absolutely NEEDS! Thanks for being awesome
Great video, beginners and experts should always verify with a meter that there is no power. Never assume anything and always know, even after verifying that the power is off always treat it like it is on just to be safe.
Great video. I looked on their website and saw they also sell a shelving unit which contains to the bus bar for multiple batteries. Maybe they'll be nice enough to send you one so you can show that. I truly enjoy your videos and thank you for sharing your intelligence.
This is the level of expertise we need on RUclips to help people to transition to renewable energy. Will Prowse sets the bar - others need to watch & learn, then up their presentation quality to match. NOTE: we're not going to keep global warming to under 1.5C, but with more & more people transitioning to solar power we might be able to keep warming below 2.5C. We have a chance if the solar power transition is going to be simple, inexpensive and reliable. Rack mounted LiFePO4 batteries like these are a huge step towards these goals.
its a pipe dream for the masses and it is far from stopping "global warming" that's the other lie.... nothing about solar will "save the planet" period!
@@OFFGRIDwithDOUGSTACY Agreed. The mining, manufacturing, and transport of photovoltaic components grossly reverses any supposed temperature shift. . To those massive costs, add the degradation of the mining site, the surrounding communities, and the long-term hit on water quality. . Then add the profits -- paid by the end-user -- required to re-pay bankers for the use of their capital. . Today and perhaps for another decade, photovoltaic is merely an expensive hobby.
Thank you so much for "ELECTRICITY EXPLAINED VOLTS AMPS WATTS FUSE ETC.... GIVES THE WHOLE "VISUAL" TO UNDERSTAND" IT IS NOT ONLY YOUR KNOWLEDGE . BUT GOW YOU "SHARE IT THAT MAKES YOU AN EXCELENT TEACHER. YOU ROCK. LONG LIFE AND A HEALTY ONE.
Looks good, 100% agree with the Class T fuses, We have 4 strings of cells here and each string has it's own fuse. I have seen some systems using standard auto type fuses and those will not break the current.
EATON Busmann (or Renology, or Victron) ANL fuses are rated at 80Vdc and are suitable for short circuit protection on high current applications, from 35A to 750A, but do not offer simple isolation/disconnect - so you'd have to add a separate disconnect if you wanted to comply with Growatt's user manual.
I am building an Outback Radian 48v system this weekend using the server rack batteries, be glad to get off the generator, we were spending $3000 a month on gas during the summer to stay cool.
I love it, we got this system in October - 12kw inverter, 6x 100ah batteries, and 8kw of solar panels. Really great to see you put it together before we do. Thanks!
Thanks for all the awesome videos! Nobody does it better. The one thing I would like to see added to your channel is more discussion of hybrid systems. I want to use a system such as the one described in this video, but slightly larger, connected to the main panel in my home. I don't wish to feed power back to the grid, but do want to use solar as a primary source for whole house power with grid backup and supplementation. I know I cant afford an off grid system that will meet all my needs, but do believe that I could build a hybrid system that would meet 80-90% of my needs, offset my utility bill dramatically, and provide a day or two of backup power for when the grid goes down. However, I've seen conflicting information regarding components required and would love to hear your professional opinion. Cheers!
Thank you, Will. For someone who has never done it before, specifying and putting a system together can be totally mind numbing, so this video in particular has convinced me that I can get a system like this, probably the same as this, up and running and doing the job and helping me understand and get used to how it all works. Really really helpful!
I am sticking to 12 volts for the time being as my system is very small, just 240 watts of panels. But good advice for when i want to upgrade to a higher voltage system. Nice informative video thanks and Greetings from sunny Jamaica.
Hey Will, so happy you are explaining this to us. I tried contacting Signature Solar and got a run around- it seems like they don’t want to talk to anyone about ordering a system-it’s like they will only speak to you if you already know what you need- no guidance or discussion
So easy to understand and carry out. It creates colossal confidence to carry it out yourself. Well done, Will, It is so informative and enjoyable to watch.
Great job of pointing out the advantage and safety of a 48v system. Will, will you ever do any videos on grid intertie ? Maybe some advice for on-grid folks who want to go solar but don't want a giant bill ?
Thank you Will. I'v been watching you on RUclips for 2 Years. Your information in simple but very valuable. I'm going to be putting a solar PV system in the Philippines to power a house. Your information has made me feel more confident with building a system.
Objection. You can turn off solar panels. Either work at night or throw a thick blanket over them and they output no power :P Jokeing asside I do get your point on those being the most dangerous.
I am a really concidering purchasing a solar panel kit, but include a solar generator until I can afford the batteries. I am also thinking about a generator to add to the system. You have definitely assisted in bringing me closer to pulling the trigger and not going with a company grid tie in system. I salute you for providing so many people with knowledge to save themselves headaches with common mistakes and product reviews that I believe was sufficient enough to provide me what I need and at least deliver on what is in their product descriptions. So thank you and keep up the good work.
Excellent video Will ! Great to see how things have evolved over the past 2 years and how it is becoming relatively simple to put together a real-life capable system
Thank you so much Will for helping us understand how to diy solar. I don't think this will power our AC deep well pump (3/4 hp), but it will power a lot of things. We will probably just need to use a gas generator to power our well pump. Rest well and Happy Memorial Day!!
Very good Diy Solar King, a very clear and easy to understand keep up the good work. People right now need diy tutorials especially on Solar to help them save money.
Hi Will, the safety points are very important. While some people survive shocks, others don't. It's best to treat anything over 30 volts the same way you handle a gun -- like it always has the potential to kill. Over 30 volts can overpower your nervious system and result in the can't-let-go effect, resulting in extended shock and high potential for death.
Good points. I noticed he doesn't use non-conducting tools specifically made for electricians, which is a must for these voltages. Gloves would be a good idea as well.
Thank you soooooo much for doing these videos. For us who do not know anything about a solar systems and living off grid this is a gem. I am watching your tutorials for over a year and finally decided to make one of my own following your videos.
Its always a good idea to use the correct size ring terminals to ensure enough surface contact to prevent creating a point of resistance that can heat up and choke current flow. Even with the nuts on I can see a gap between the terminal. I know you know this and that cable looks oversized but it would be great to make a mention about terminal connections as they are almost more important than the cable itself as they can often create bottlenecks. Great video though Will, The cost in copper alone is enough of a justification to use a higher voltage system and cheap CCA don't cut it.
instead of using an extension cord, it is better to cut the plug off a power strip. It may be a cheap overcurrent protection device but better than nothing! It is also a good idea to tin the leads so strands don't separate. It can be difficult to get all the strands in
If it's consuming 10,000 watts to go at speed of 40mph then 2x 13,000w of solar pannels will be required. Would end up using 62 pannels ratted at 445w per panel and if you would like to go 60mph consuming about 25,000 watts of energy and 5000 watts for charging the battery. Yep that's the math for what's required to run. Not fatoring in the drag of the pannels or the weight.
Will, thanks for this video. In addition to running my Small building (man shack and ham Radio Station) With a 48v battery setup how would you suggest a way to run 12vdc appliances ( 20A loads) in addition to the GrowWatt inverter for 120vac? I want to use 12vdc for radios and a few 12vdc items. The max load on the 12vdc side will be about 40amps TIA Lloyd KO4L
Hi Will , i really enjoy your videos . I recently subscribed to your channel . I think my needs are less complicated . I am off grid and have been for 5 years now . I installed two sets of used solar panels , 1000 watts each . I use the power as 12 volts to run all my lights and charge ports . I did have 5 deep cycle batteries and now only have one . I was using my fridge but now i can't . The fridge is both 12 and 24 volt , the brand is UNIQUE . I live small in everything 24 " tv 35 watts , water pump not connected and an on demand hot water tank LPG i still need to purchase . That is all i have . Would you be able to suggest a system for my needs ? I will be applying for a government grant for repairs that i would like to include this part of the expense . I am on a disability pension . Any help will be greatly appreciated . Thank you so much . Perry .
My father was a senior electrical engineer at Boeing helicopters in Ridley Park. He's been telling me since I was a child, it only takes a third of an amp across your heart to stop it.
A little tip: if you have some red electrical tape, wrap a little around the pos(+) MC4 connector so that you'll never get them mixed up. A lot of us forget what we did, months or years afterward.
Martin, I am a semi-retired welder-fabricator. I create a op manual for everything -- parts numbers, suppliers, components, procedures. I automatically assume the next user is a lawyer intent on making my life 'difficult'...
Would love if you makr a video of connecting one of these 48v systems to a sub or critical loads panel. Youre great at explaining these things in detail
You da' Man! I have been watching your videos for almost a year now, I like how you approach projects by breaking them into their individual components. Great videos. I feel like I have gained real-time knowledge that I can build on after watching your content. I am left hungry for more of your generated content when I am done watching an episode. And just like eating at a great diner, I cannot stop thinking about the food I had for the rest of the day, lip-smacking good as they say. That is how I feel about watching your channel, the more I watch, the more I thirst for more of your excellent content. Thankyou for making the University of RUclips so much better than the sum of it's parts. Some (Not all) of the channel creators produce 57 minutes of blathering about their obvious neophyte inexperience that cloaks bad content; that could be edited down
I setup this exact system and it was pretty straightforward. The hardest part was setting up the solar panels. I am going to install a sub panel next to this with 3 circuits on it and a 30 amp output fuse. Basically going to use it to run 2 refrigerators, a freezer and my office PC along with a couple other small things. Would love to setup a 240v system but determined would require too many batteries.
As always, mount these inverters to a non-combustible surface, such as hardiboard. It costs $10 and will increase your peace of mind. Also, avoid combustible materials within a 4-foot radius. Check out this video where I show how to do this: ruclips.net/video/01qYerhorwU/видео.html
The unit was not charging because I forgot what model I was working with. It requires 120VDC minimum at the input to work. And it has a max input voltage of 250V. I don't know how I messed that up. I was just using the 148VDC max model the day before, so mixed it up.
Also, use the proper terminal ring hole size for your inverter. I use these on multiple inverters, so they are huge.

Will I received my Jakiper 48v Battery (with a bent handle) and my Growatt 48v charger, and would like to know what size cables you used for the battery...
@@ricardocastaneda8276 0 gauge is overkill and works great. Each manual will recommend a different size though. Some are ok with 2 or even 4 gauge, but you need to check the manual.
@@ricardocastaneda8276 how bad is the bent handle? That's not good
We have 2 5k Growatts w 4 of the EG4 batteries (budget version). I would love to see this system with the transformer. Thank you so much for this video!!
do you need to wire the ground connection to the earth with a copper rode?
I enjoy hearing you say tighten.
Retired elevator man here. When working on live circuits. Keep one hand in your back pocket. Less chance of going thru your heart. When engaging a disconnect turn your face away from the switch. When it goes south they explode like a bomb.
I watched electroboom use a ground bracelet but it still hurt him but probably kept it from his heart
@@davelaseer1344 Back in the 1970 and 80's elevator machine rooms were not air conditioned. Pre computerized age, that 140 degree sweat box was all summer long. So you were dripping wet and always working on live circuits between 48VDC to 240VDC and 24VAC to 440VAC. In tight places sometimes wore latex gloves to try and keep from getting a jolt. WE used insulated floor mats around controllers. Just assess the environment and mitigate the chance of getting shocked or hurt. Made it 40 years without a single serious accident for my workers under me or myself.
@@vanpeters9751 hh.
Always wear protective glasses.....molten steel,copper and plastic don't go well with your eyes....
@@demolitionkid2 still turn your head away. I have first hand experience with a couple of 440VAC disconnects exploding when turning on and off. 40 years working on many live controllers, motors, generators and inverters made me very cautious. Kill power whenever you can and use all the PPE and hazard prevention available.
Coming from someone that has gone to school for Hybrid vehicles and high voltage systems, always assume there is voltage at the terminals until you check them with a multimeter! (You should always check with a multimeter!) never assume a high voltage switch is operating properly until you verify it!
100% bro always on until I’ve checked!
well if you really want to get technical about it you should do a "live dead live check" (NEC 110.4) . check meter on live circuit to confirm its working typical and outlet or dedicated tester, test the circuit you are interested in working on, then test on a live circuit again to make sure the meter didn't die when you tested your circuit of interest and is just showing no voltage. sounds like overkill personally I only ever did it when doing 480Vac+ stuff
@@orbitONhigh In this case i would just switch the switch to on and measure and then off again and one should know enough if the meter is working , if both states dont show anything then the meter is broken or the source you trying to measure is a case of a problem
@T.J. Kong
Yes, they have a service disconnect which cuts the battery in half. There is also a fireman’s loop where then can easily cut the cable to quickly disable the system.
Just like shooting guns. Always assume it’s loaded and live before pointing it. Verify the safety first. Would have been a good rule for Alec Baldwin to follow.
The 'only' downside of touching a 48v full battery is instant death! lol. love your videos man. i've learnt so much from this channel.
hilarious
Hi, Will! We are older folks who have interest in this kind of thing, but are rank beginners! It is always a pleasure to watch your videos...you do an excellent job explaining things to us folks just starting out!
Keep up the Great Job!
God Bless!
@Tessmage Tessera I'm 57 and I'm pretty sure I'm gonna blow myself up. Being paranoid has probably kept me alive so far though.
I’d have to say at 54, I have a good understanding of electrical properties but a bad understanding of “best safety practices”. These videos help enforce things we may overlook.
@@tblbaby Yup, I'm your age and am usually paranoid enough to be safe. But Will point about voltage through the heart rang clear for me. I was a career Law Enforcement Park Ranger, in Utah, I was assisting an elderly person change their flat tire. A dark set of clouds came over the mountain, lightning hit the ground about a quarter mile away from me, however I was holding the tie rod in both hands, and a huge electrical current went through my chest cavity. Never thought I could be a human lightening rod. Took a couple of hours from the chest pain to subside. (Didn't get any super powers either:( ).
@@SuperJamster1 YeeOuch! My dad was holding on to a fence and lightning struck it far away, knocked him on his ass. I stepped out of a puddle in the rain just before lightning sent a jolt through a cable on a power pole and into the puddle. I've been shocked many times. 220 dryer, 100 cycle jet engine test cell short through my head lol. Fell off a tree into a full ditch head first having my legs tangle up in electrified barbed wire and having to rip my pants off it to get out as it was jolting the hell outa me. Fun stuff like that. Never got the lightning through me though, thankfully :))
@@tblbaby Ha ha I love those stories. I've had my share too, including electrical fences. But my favorite is when I was working on wiring some 12 gauge in my barn and my wife decided to throw the outdoors panel breaker (old tube fuses) back on. Guess she wanted to see if my life insurance was up to date.
As a newbie, I have never commented on anybody’s videos. Until now. The value that you offer is among the highest I’ve ever seen. Your degree of clarity, matched with your passion, is outstanding. As a general comment, keep it up. We all very much appreciate it.
Well this is funny timing. But so thankful. We’ve put half of our 10 kw Growatt system. And been using it, a month. We bought the other array and got it installed last weekend. Today, my husband will tie that array in. We’ve gotten 2 of the 6 batteries in. As soon as my husband gets out of bed this morning he’s going to watch this. I’ve been worried about tying all the components together, but Wonderful Will has been helpful all the way. Thank you!
Thank you for the safety tips.
When I was a young guy still in elementary school 4th grade. I was outside flying my kite one day in Irving Texas. Somehow my kite got stuck on top of the school house building. Only way I could see to get up there without a ladder as I was quite the climber young and agile. Not so much at age 62. Anyway I saw a place I could put my hands in to climb up. Me a ignorant fourth grader I put my hands inside this somewhat small box to pull myself up further to potentially climb on top of the roof. I quickly found that it was an electrical meter without the face cover on it. Needless to say I got hit with some serious electricity. Which caused my hands and muscles to immediately clinch I felt the current very strongly all the way up to my shoulders. As my feet were on the aluminum sided building fortunately I had enough leverage to break free and fall on my back. I can't recall even thinking about this event since that day and some weeks after. For some reason you're very intelligent teaching brought it to memory. Thank God I had my tennis shoes on if I hadn't I wouldn't be here today. We used to run around in bare feet quite often in the hot Summers of Texas. Over the period of my life I've had many close calls with death which I'm not going to bore you with now. Clearly our creator has plans.
I'm in the process of building a 48 volt system with a battery Bank of 48vx304ah. For my box van RV conversion.
Thanks for going over the simplicity of the set up. I will be looking for the video where you build a bigger system with more batteries and can show the proper set up of the bus bars and those t fuses. Thanks for the reliable information Will!
I’m a Union electrician in NYC. 35 years experience in ALL phases of electrical work. 48V is the line of delineation between “high” voltage and “low voltage. It also separates electricians from data technicians mostly because back in the day most telephone circuits ran on 48V systems. And to be honest 48V kinda tingles a bit of you get hit by it. You would never want to be holding it when the phone rings. That closes the circuit and that’s when it hit’s you. It’s a long running joke amongst veteran electricians.
I would love to help you out when you decide to start enclosing your wiring in some conduit. Good job Will
✊🏿
Phone ringing voltage is much higher than 48V DC. More like 96V AC with multiple frequency options to support party-line ringer selection.
I like the simplicity of teaching here. Another thing to consider is if the person is still leery working with the voltage on the solar panels, they could wait until it's night so the voltage and amperage of the panels is at its lowest.
The hardest part is coming up with the coin to buy all the components. :)
Man - I dont personally have a solar system - yet. But the enthusiasm that Will shows during his videos is great. Dude genuinely loves doing what he does and it shows.
I suggest a cheap lock out tag on breaker. Even a piece of tape over breaker reminding you to double check before removing tape.
Even a quick check list before you remove tape.
I know when I see the 'plywood blank canvas' up, I'm in for a Will-full edu-ma-cation fer sure!
Thanks and gratitude for all your enthusiasm, open-source info and holding these manufacturers to account for shortcuts and shortcomings. You da man Will!
This is the simplest explanation and use of components ive ever seen on RUclips.
I built an off-grid solar battery (after the great Texas Freeze last year), have 6x100W panels and a 300amp/h battery connected. Spent about 3K total on the project and super happy that it can take anything I throw at it. Not a 1-1 grid replacement but definitely piece of mind.
“if you get enough current to flow through your heart you are instantly dead 😶… but that’s the only downside! 😄” something about his delivery on that line cracks me up
You do a great job explaining very complex and dangerous equipment. I appreciate the way you emphasize safety and explain how o.1 amps of current can kill you. Thanks for making this so easy to understand.
Been shocked many times by 240v, only kicked like a mule and my heart is still functioning. This same thing has happened to manyy electricians I know and they are still alive.
Would love to see a larger 48v system for off grid home, especially how to wire the panel if thats possible.
I’ll be installing my 48v system in Jan. always learn something new every time I watch Will vids
check david poz hes got 3 in his system if remembering right there growatts too and 6 of the rack batteries in a rack with common buss bar
@@jar407 will do, thanks!
The thing about wiring a panel is that the knowledge base for a panel is like a 5gal pail whereas installing this small AIO setup the knowledge needed is akin to 16oz bottle. You can safely install the AIO with step-by-step instructions but a panel has so many variables and alternative paths in the flowchart. One video probably can’t tell you everything you need to know.
@@fishhuntadventure no doubt, thats why i said if possible. At least some basics as the extension cord doesnt help to run a whole house which is what im planning. Im sure its complicated and has liability along with it, but its also necessary and valuable info.
My dad mentioned you could connect your final solar array MC4 at night. Then you wont have any power... The other thing I was going to suggest is adding red tape to your MC4 adapters so that you don't get it wrong. Thanks Will, great videos. Super helpful for sure.
Will! You're amazing. I have a similar history as you, with the medical issues and surviving in an RV without family help. Doctors have been no help, so I started reading medical journals and dictionaries to figure it out for myself. After years of struggling, now I'm healthier and have my RV gutted, about to buy a 48v hybrid system and a mini split to install. Thanks for putting your inspiration out there for us. :) I'm glad you're getting along better now.
You know, when I first found your channel everything was so damn daunting. Felt like the first time I build my computer all over again, after some months though, the hardest part is saving up for all the parts in one go.
Thank so much Will, your videos helped me put a 300 watt solar system on my teardrop trailer for of grid camping. now it’s time to add a 48 volt solar system to my house. You have given me confidences to try it on my own.
Great simple video. One suggestion, connect your loads prior to sources when possible to further eliminate any potential of electric shock.
A lot of times I don't ever plan on building some of the things you have videos for BUT I still watch them because I ALWAYS learn something new. And also your presentation is awesome!
Thanks Will...
Always being forefront on safety tips helps put to rest some of the worries of a 48v system. Thanks!
Great and needed video, Will. Solar is a great hobby but high voltages will kill you. These all in one systems are very safe if you are careful. I am an electrical engineer and Will’s practices in this video are rock solid.
Brilliant! These instructional videos are invaluable as they save many lives in addition to educating millions. Teachers like you do great public service and I hold you in high regard. You are like the Khan academy for this domain.
1:38 "only negative is that 48v will kill you". "If the current flows, you are instantly dead" (will prowse laughs) 😂. Thank you for the wonderful simplified tutorial
This video is pure gold. Educational without any b.s.
First time I've ever felt like I owed someone money for knowledge.
I'm an old guy that has actually learned much from you regarding PV panels and storage batteries and has built a small 12 volt back up system for tornado season here in Kentucky using info I got from your channel.. My wife and I both are grateful for your channel for that reason. A really silly thing that I would like to ask you, that has zero to do with solar or batteries is, where did you grow up? The reason I ask is because the way you pronounce words like "tighten" is much more "precise" that anyone here in Kentucky would pronounce them. It may not be a regional thing, because you seem to be very well educated and may just say things "right" for that reason, but I'd really like to know, if you don't mind sharing. One of my "things" that I tend to pursue when I meet new people.
I finally got my system built and operational in October. I studied for 3 years, buying panels and watching you and David Poz. I made my own adjustable array with a combination of sixteen 350W and eight 315w panels, 2 strings of 12 each. Went with two 48v banks of Rolls S6 L16 FLA batteries @ 445AH for a total of 890AH. Went straight to the top and got a Sol-Ark 12K. Added a Winco propane 8K standby generator. Love the SOl-Ark. It's not "set-it-and-forget-it", but it's ability to direct the greatest input to the most needed output is outstanding. The auto start feature for the genset is just fabulous. The videos are unlisted, but if you should have any interest in seeing the build, I'll send you the links!
Learned a LOT about FLA's. Properly maintained, You can get better than 10 years out of them. Believe me, I did some thorough researching before choosing FLA. They match my personal parameters for output, maintenance, cost and life expectancy!
I had backwoods solar design a system for me and so far I have my solar panels mounted with a 1000 gallon propane tank and a 12k Cummins generator behind the panels. We’re running 180’ to the house after combining two 4 panel sets. The panels are 385 watts each and they’re 48 volt panels. We just got the upstairs closed in but now we need to pull wires and wire the house and we’re going into the deep freeze for a while like -10-20 below zero at night. I can’t wait to have it all hooked up! We will be supplying energy for a SIP house that’s 28x32 on a walkout basement. Heat will be supplied by a propane fired by a modulating boiler hooked up to infloor heat in the basement and baseboard upstairs and wood stove will supplement the upstairs so hopefully that thermostat won’t ever call for heat.
Your youtube content is interesting. I like your old school approach (I am old school as well).
I am interested in the info you have for your solar installation, if you're still offering...
Thanks in advance.
solark might be great but so are the price 6900. plus batteries plus panels . wills system showed 1500 t0 1800 battery 800 for all in 1 and 1000 panels 3600 total. yes smaller system but many off grid its plenty
bigger systems are different and your inverters possibly the best
i went rolls twice and regret ever buying them... they wont last more than 3-4 years.
@@baby_UFO Their literature is the most thorough I found, and the tech support supplied quite an education. I noticed my specific gravity was never coming all the way up. Since I programmed 890Ah, the controller drops to float voltage when it sees current drop to 17.6 amps to the batteries. They were not sufficiently charged to bring the specific gravity back to specs. Rolls rep had me reset the AH rating to 800. This caused the controller to drop back to float voltage at 16 amps instead of 17.6. That translated to more hours of charging at 60 volts. The other issue I had was the Sol-Ark shut off the generator when it hit the float voltage of 54.7. On solar, the output to the batteries is 61.4 volts, with amperage determined by battery resistance. (charge) The bulk and absorption voltage is set at 60, but temperature compensated for 45 degrees F, hence the 61.4v. On the generator, the output is limited to 4400 watts i.e. 80 amps and the voltage remains lower than float. As they charge, resistance increase and the voltage rises until it hits 54.7v. It appears that Sol-Ark has programmed their system to determine float by reading amps while on solar, but using float voltage setting to turn off the generator. Since it has been cloudy for a month or more, I reprogrammed the float voltage to 61v to prevent the generator from shutting down at 54.7 volts. Yesterday was the first time since October that my specific gravity came all the way up to 1260+. Checking specific gravity is an absolute must to determine the charge of a FLA battery.
I did all the HEV and BEV diagnostics for Ford from 2010MY through 2016MY. Nominal pack voltage was about 320VDC if I remember right. Anyway, I always used an old trick of Nikola Tesla's, regardless of whether the service plug was pulled or not. When working with HV conductors, keep one hand in your pocket.
Just starting the learning process. We’re living in the tropics and for the start… run an AC unit and Fridge. No need to cover much else. Cooking is gas. I like the idea of 48v. Definitely not 12v but maybe 24v. Want to be able to expand for full off grid. AC worst case is 24hr. The plan is to tip the panels at 3 periods of the day. Friend of mine does that. Amazing how much difference it makes. He ran a well pump to show the difference… wow
I used Will's suggestions to build a solar system for an off-grid property. Dude knows his stuff. Will, could you do a guide on an off-grid battery set-up for cold climates (not in a heated house or anything)? Thank you again!
So far the best and clear explanation without unnecessary information. 10/10
That’s the best set up system I’ve ever seen!!! Simple, quick, straight to the point, and good to go!! Thanks for sharing!! 👍🏼😎🇵🇷
I have to say I've been a bit intimidated by figuring out how to setup like 3 x 100ah batteries, all the shunts, fuses, etc when I go to set up everything for my cargo trailer conversion but what you just showed me in this video has turned me to 48v setup just like this and not deal with 12 volt. I just would need to get a 48 v to 12v step down to power puck lights etc. If you could show us how to connect a dc to dc step down in a setup like this it would make my life SOOOO much easier. I was going to spend so much money on Victron stuff but I think that Growatt would be perfect for me and a server rack battery. Way less wires and stress! THANK YOU for the video sir!
The fact that it's getting easier to assemble these systems is great. The one thing I need more guidance on how to size the system I need based on usage. For example, I'd like to start with an off-grid system that powers my refrigerator in the garage. Then later, power my outdoor power tool battery chargers, then ultimately, charge my Tesla.
I would get a Kill-A-Watt meter. Plug it in-line with your fridge. It will read your electrical load. Find out, over the course of a month, your average KWhr load of the fridge. Mine drew about 2kwhr a day. The next thing is to figure out how much solar you need to generate 2 kwhr. If there is no shading, in the tropics you get about 3-4 times nameplate wattage in energy. So we had a small 660 watt system on a boat and had the equivalent of about 3.5 hours of full production, so about 2310 watt hours or 2.3 kwhr. That would run a fridge, in good conditions, but obviously if it’s cloudy or rainy, we would make less than half that. So either you would want to upsize solar or battery capacity to get through those days. In the northern climes, you may only get 2 equivalent of 2 hours peak production, or maybe 1.3 kwhrs. So it depends on where you live and where the panels are mounted. Snow. Shading, ect. My recommendation, mount as many as practicable, and then figure out what you can run. Because if you mount 4, your going to be thinking about 4 more within a year with expanded use. Cheers
Thank You! I have recently bought a Growatt as well. I have no knowledge of electricity at all, but I managed to connect an Axpert inverter 2kv. Using two 12v connected in series.
The Axpert died on me recently! So I bought this Growatt! But all of a sudden I am fearful to connect this! First is that I may damage the unit, secondly its death ... I am currently connected using one of those boat inverters! This one does not scare me at all!
The all in one inverter package is the way to go. Keep it simple
Brilliant, funny though the only major drawback is death through voltage . Such a valuable demo . Thank you
THANK YOU Will. We need more focus on 48v systems using server rack batteries! Videos on cheap 12v batteries being cut open are soooo 2020.
I can only imagine that ALOT of those battery companies HATE the sound of that saw firing up.
Lol! why would we criticize such a beautiful works sir? No need but only to appreciate your effort. Your explanation is amazing. i am an electronic trainer by profession but you are the best. Keep it up. I follow and watch your videos ever since I knew you.
Read my mind with this one! Loving what seems like an increase of videos from you lately. Some would say that you could of watched the 24v video but you supplied so much more information that a beginner like me absolutely NEEDS! Thanks for being awesome
Great video, beginners and experts should always verify with a meter that there is no power. Never assume anything and always know, even after verifying that the power is off always treat it like it is on just to be safe.
I am bringing my RV to you to get my 1000 A/H System up and running ;) Love all your vids!
With your teaching i was able to install 2 Growatt SPF ES in parallel for a friend In ABIDJAN Cote d'ivoire and one in LOME TOGO
So when handling 48V systems, treat it like you are handling an active 120v AC line. Got it!
Great video. I looked on their website and saw they also sell a shelving unit which contains to the bus bar for multiple batteries. Maybe they'll be nice enough to send you one so you can show that. I truly enjoy your videos and thank you for sharing your intelligence.
This is the level of expertise we need on RUclips to help people to transition to renewable energy. Will Prowse sets the bar - others need to watch & learn, then up their presentation quality to match.
NOTE: we're not going to keep global warming to under 1.5C, but with more & more people transitioning to solar power we might be able to keep warming below 2.5C. We have a chance if the solar power transition is going to be simple, inexpensive and reliable. Rack mounted LiFePO4 batteries like these are a huge step towards these goals.
its a pipe dream for the masses and it is far from stopping "global warming" that's the other lie.... nothing about solar will "save the planet" period!

Agreed.
The mining, manufacturing, and transport of photovoltaic components grossly reverses any supposed temperature shift.
.
To those massive costs, add the degradation of the mining site, the surrounding communities, and the long-term hit on water quality.
.
Then add the profits -- paid by the end-user -- required to re-pay bankers for the use of their capital.
.
Today and perhaps for another decade, photovoltaic is merely an expensive hobby.
Very good video, short and to the point. Yes you can go on for considerably longer, but for a basic system it really is that simple.
Thank you so much for "ELECTRICITY EXPLAINED VOLTS AMPS WATTS FUSE ETC.... GIVES THE WHOLE "VISUAL" TO UNDERSTAND" IT IS NOT ONLY YOUR KNOWLEDGE . BUT GOW YOU "SHARE IT THAT MAKES YOU AN EXCELENT TEACHER. YOU ROCK. LONG LIFE AND A HEALTY ONE.
Looks good, 100% agree with the Class T fuses, We have 4 strings of cells here and each string has it's own fuse. I have seen some systems using standard auto type fuses and those will not break the current.
EATON Busmann (or Renology, or Victron) ANL fuses are rated at 80Vdc and are suitable for short circuit protection on high current applications, from 35A to 750A, but do not offer simple isolation/disconnect - so you'd have to add a separate disconnect if you wanted to comply with Growatt's user manual.
I am building an Outback Radian 48v system this weekend using the server rack batteries, be glad to get off the generator, we were spending $3000 a month on gas during the summer to stay cool.
Organized and well explained as always Will, I'm glad you keep us novices in mind when explaining these systems.
I love it, we got this system in October - 12kw inverter, 6x 100ah batteries, and 8kw of solar panels. Really great to see you put it together before we do. Thanks!
Wow, this might be my favorite video yet. It's hard to make things simple. This is awesome!
Thanks for all the awesome videos! Nobody does it better. The one thing I would like to see added to your channel is more discussion of hybrid systems. I want to use a system such as the one described in this video, but slightly larger, connected to the main panel in my home. I don't wish to feed power back to the grid, but do want to use solar as a primary source for whole house power with grid backup and supplementation. I know I cant afford an off grid system that will meet all my needs, but do believe that I could build a hybrid system that would meet 80-90% of my needs, offset my utility bill dramatically, and provide a day or two of backup power for when the grid goes down. However, I've seen conflicting information regarding components required and would love to hear your professional opinion. Cheers!
I'm with Craig!
Yes, definitely!
Same here
Thank you, Will. For someone who has never done it before, specifying and putting a system together can be totally mind numbing, so this video in particular has convinced me that I can get a system like this, probably the same as this, up and running and doing the job and helping me understand and get used to how it all works. Really really helpful!
I am sticking to 12 volts for the time being as my system is very small, just 240 watts of panels. But good advice for when i want to upgrade to a higher voltage system. Nice informative video thanks and Greetings from sunny Jamaica.
Laudamurcy
@@pr0n5tar lol @ you Jamaican too.
Yes sir. Jps is steering me in thia direction but lack of funds ... studying the methods and the products so when my time comes im on top of things
Hey Will, so happy you are explaining this to us. I tried contacting Signature Solar and got a run around- it seems like they don’t want to talk to anyone about ordering a system-it’s like they will only speak to you if you already know what you need- no guidance or discussion
"With this system you can die!!! [smiles] But that is the only downside!" made me chuckle :) Love your videos, learned so much from them!
So easy to understand and carry out. It creates colossal confidence to carry it out yourself. Well done, Will, It is so informative and enjoyable to watch.
Great job of pointing out the advantage and safety of a 48v system. Will, will you ever do any videos on grid intertie ? Maybe some advice for on-grid folks who want to go solar but don't want a giant bill ?
Thank you Will.
I'v been watching you on RUclips for 2 Years. Your information in simple but very valuable. I'm going to be putting a solar PV system in the Philippines to power a house. Your information has made me feel more confident with building a system.
Objection. You can turn off solar panels. Either work at night or throw a thick blanket over them and they output no power :P
Jokeing asside I do get your point on those being the most dangerous.
Solar panels can have a high open circuit voltage under moonlight or if someone shines a little flashlight on them...
I am a really concidering purchasing a solar panel kit, but include a solar generator until I can afford the batteries. I am also thinking about a generator to add to the system. You have definitely assisted in bringing me closer to pulling the trigger and not going with a company grid tie in system. I salute you for providing so many people with knowledge to save themselves headaches with common mistakes and product reviews that I believe was sufficient enough to provide me what I need and at least deliver on what is in their product descriptions. So thank you and keep up the good work.
Excellent video Will ! Great to see how things have evolved over the past 2 years and how it is becoming relatively simple to put together a real-life capable system
Thank you so much Will for helping us understand how to diy solar. I don't think this will power our AC deep well pump (3/4 hp), but it will power a lot of things. We will probably just need to use a gas generator to power our well pump. Rest well and Happy Memorial Day!!
yes thank you
Very clear and understandable instructions for the system for beginners. I hope to give this a try
You teach us a best simple way as plug-and-play. Can we use this system on the van conversion??
Yes you can but you should stick to the 12 or 24 volt system as a safety standard for a moving vehicle, 48 volts are no joke...
Very good Diy Solar King, a very clear and easy to understand keep up the good work. People right now need diy tutorials especially on Solar to help them save money.
Hi Will, the safety points are very important. While some people survive shocks, others don't. It's best to treat anything over 30 volts the same way you handle a gun -- like it always has the potential to kill. Over 30 volts can overpower your nervious system and result in the can't-let-go effect, resulting in extended shock and high potential for death.
Good points. I noticed he doesn't use non-conducting tools specifically made for electricians, which is a must for these voltages. Gloves would be a good idea as well.
I was taught to always “test for dead” before starting work, you only have to get it wrong once.
Thank you soooooo much for doing these videos. For us who do not know anything about a solar systems and living off grid this is a gem.
I am watching your tutorials for over a year and finally decided to make one of my own following your videos.
Its always a good idea to use the correct size ring terminals to ensure enough surface contact to prevent creating a point of resistance that can heat up and choke current flow. Even with the nuts on I can see a gap between the terminal. I know you know this and that cable looks oversized but it would be great to make a mention about terminal connections as they are almost more important than the cable itself as they can often create bottlenecks. Great video though Will, The cost in copper alone is enough of a justification to use a higher voltage system and cheap CCA don't cut it.
Absolutely. CCA is awful.
And yes good point about the correct size ring terminal. Should have mentioned that.
Those bottlenecks can create a lot of heat sometimes!
You are too good
Can watch your Videos any time any moment , you are a great teacher
instead of using an extension cord, it is better to cut the plug off a power strip. It may be a cheap overcurrent protection device but better than nothing! It is also a good idea to tin the leads so strands don't separate. It can be difficult to get all the strands in
Just beginning to watch your videos. Each one builds my confidence every time. Soon, soon, I'll take the plunge. Thanks, Will!
Wish I'd gone 48v instead of 24v for my system. I'd have gotten ~2x the capability for no more cost, and possibly lower cost.
Thanks, I just bought the Growatt 5K and 3 rack batteries . I'm a DYI guy and didn't have a clue... Love your tutorial !!!
Will, what kind of solar electric setup would be needed to keep a 2022 Sienna running full time in EV mode?
If it's consuming 10,000 watts to go at speed of 40mph then 2x 13,000w of solar pannels will be required. Would end up using 62 pannels ratted at 445w per panel and if you would like to go 60mph consuming about 25,000 watts of energy and 5000 watts for charging the battery. Yep that's the math for what's required to run. Not fatoring in the drag of the pannels or the weight.
Well I just picked up my 48 Volt from Signature Solar today and this makes me want to return it.
Will, thanks for this video. In addition to running my Small building (man shack and ham Radio Station) With a 48v battery setup how would you suggest a way to run 12vdc appliances ( 20A loads) in addition to the GrowWatt inverter for 120vac? I want to use 12vdc for radios and a few 12vdc items. The max load on the 12vdc side will be about 40amps TIA Lloyd KO4L
No criticism required, excellent presentation.
Hi Will , i really enjoy your videos . I recently subscribed to your channel . I think my needs are less complicated . I am off grid and have been for 5 years now . I installed two sets of used solar panels , 1000 watts each . I use the power as 12 volts to run all my lights and charge ports . I did have 5 deep cycle batteries and now only have one . I was using my fridge but now i can't . The fridge is both 12 and 24 volt , the brand is UNIQUE . I live small in everything 24 " tv 35 watts , water pump not connected and an on demand hot water tank LPG i still need to purchase . That is all i have . Would you be able to suggest a system for my needs ? I will be applying for a government grant for repairs that i would like to include this part of the expense . I am on a disability pension . Any help will be greatly appreciated . Thank you so much . Perry .
Perry,
Please, more information on grants!
My father was a senior electrical engineer at Boeing helicopters in Ridley Park. He's been telling me since I was a child, it only takes a third of an amp across your heart to stop it.
Drink every time he says "tighten"
Tie... Ten.
A little tip: if you have some red electrical tape, wrap a little around the pos(+) MC4 connector so that you'll never get them mixed up. A lot of us forget what we did, months or years afterward.
Martin,
I am a semi-retired welder-fabricator.
I create a op manual for everything -- parts numbers, suppliers, components, procedures.
I automatically assume the next user is a lawyer intent on making my life 'difficult'...
Would love if you makr a video of connecting one of these 48v systems to a sub or critical loads panel. Youre great at explaining these things in detail
Im about to build a 48v solar system just like this one, straight up, step by step.
Thanks for the video Will!
Can't wait for a video with a set up that will power a normal sized all electric house and charge an EV. Thank you in advance!
I can't wait until I can get some property. One rack of solar, another of virtual machine hosts!
You da' Man! I have been watching your videos for almost a year now, I like how you approach projects by breaking them into their individual components. Great videos.
I feel like I have gained real-time knowledge that I can build on after watching your content. I am left hungry for more of your generated content when I am done watching an episode. And just like eating at a great diner, I cannot stop thinking about the food I had for the rest of the day, lip-smacking good as they say. That is how I feel about watching your channel, the more I watch, the more I thirst for more of your excellent content.
Thankyou for making the University of RUclips so much better than the sum of it's parts.
Some (Not all) of the channel creators produce 57 minutes of blathering about their obvious neophyte inexperience that cloaks bad content; that could be edited down
This is great. I see this could be a perfect series of start with basic and then build to the next step and next step, etc
I setup this exact system and it was pretty straightforward. The hardest part was setting up the solar panels. I am going to install a sub panel next to this with 3 circuits on it and a 30 amp output fuse. Basically going to use it to run 2 refrigerators, a freezer and my office PC along with a couple other small things. Would love to setup a 240v system but determined would require too many batteries.
