DIY: Growatt 3000 watt 24 volt Solar Generator

Disclaimer: I am not a licensed electrician. This video is for entertainment purposes only. If you follow any of my methods, you do so at your own risk.
I made this DIY solar generator. I use it for power in my ice fishing shack and for emergency power around my home. It is portable enough to take along in my trailer for power at remote locations.

@@beefitter how long have you been using the bms & how would you rate it. It looks very interesting

[@beefitter]

@@nosbig6 I have used it for about four months. I has worked great. Overkill solar has probably the best warranty out there. If you hook it up wrong and fry the BMS he will give you a new one. Read his warranty on his website. Will Prowse on his DIY solar channel, has said that the Overkill Solar BMS is top notch. If you are making a DIY setup, you just have to make sure that you are sizing the BMS properly. You can email Overkill Solar if you have questions about their product. If you are unsure about doing a build, you can always buy a complete battery, that includes a BMS. SOK makes a couple of really nice good quality batteries. SOK batteries are complete with a BMS in each battery. You just have to hook up the battery cables. The battery case is heavy duty and all of the components are replaceable. Check out Will Prowse's video on a couple batteries, he does talk about the overkill solar BMS at the end of the video. kzbin.info/www/bejne/iKmweqZmhb2leNk

I really like your rapid reconfiguration design that allows for removal from the hand truck and near-instant mounting to a fixed wall structure. Brilliant!

[@ssyoumans]

Great looking build. Tip: To pre-charge the unit, trip open the positive breaker, connect the anderson powerpole connector, use your resistor around the breaker (that is open) to precharge the capacitors, then close the breaker after 3-5 seconds.

How did your project go? Thinking of doing the same with a 5kw server rack battery.

[@Solar_and_Security]

@@Mike-. It came together well. I went with a 3kw unit, have have it at 24V, 400AmpHr. I tested it on a TV small computer, Reach in freezer, and a small ac, only hit 1200 watts. I'm about to add another 3kW unit for a little extra, security and to run a few more things. I'll run them in connected for a 6kW capability, currently do 6 panels in a 2s3p. I'll do the same with the new unit. I'd buy some used panels to keep costs down. I bought a few extra when I did, just to have materials to expand when I was able. I would recommend the same, if you can swing it. Best of luck to you Mike!

My intent is not to get around any code or permit requirements. I am not a licensed electrician. Code is there to prevent us from killing ourselves or others and so we don't burn our homes down. The code was written because of negative events that have happened over the years since electricity started being used by people. So please be careful when making solar systems.

I bought this since my previous Xantrex had just died. The Growatt lasted 5 months before showing error 19. I exchanged a bunch of emails with the Growatt support and they determined the main board needs to be replaced (after they had me take it apart) and told me to contact the seller for a warranty claim. The seller was off Amazon and is unreachable. So much for this company. I now own a $900 doorstop.

[@beefitter]

I think that when you buy this type of equipment, buy it directly from a company that sells and does the warranty. I purchased a Growatt from Watts24/7.com. They are an authorized distributor of the Growatt inverter. I had a problem with the inverter right away. I called them and I had a new inverter in two days. I have done business with them several times and have nothing but good things to say about their customer service. There are cheap knockoffs out there that unsuspecting people get ripped off.

[@MarkOfBitcoin]

Did you have the utility connected WHILE the solar panels were connected? As in, if there is solar available, does the Growatt take the solar power as preference to charge the batteries rather than using the utility power? And only when solar power reduces does it automatically use utility power?

[@beefitter]

You can set it up several ways. If you go to the Watts247 website you can look at the manual. I have done it both ways. The way I have mine set up is SBU. Which is solar, battery and utility. The inverter will use power in that order.

[@nikjim13]

Why did you go with a 80a breaker? When gathering my components and running calculators a 120 is what I'm leaning towards. With a 80 and even with my 120 we wont be able to get to the full rated output of the growatt which is good to avoid damaging but I was curious why you chose 80. Through a calculator you'll likely be able to draw around 15a ac which is 82.8a dc. With my ideal 120a dc breaker I'll be able to take 22a ac from the inverter or 121a dc from the bank. Thanks.

[@beefitter]

I went with the 80 amp because that is what the GroWatt can take 80 amps of charging

[@nikjim13]

@@beefitter Yea the growatt can put 80a back into the battery bank but I think you're limited to around 15a of ac because 15a of 120ac is 82.8a dc, so whatever power it taken from your battery bank to the growatt also goes through that breaker. Have you drawn more than 15a constant yet? I could be wrong but if you're ever near your setup with a few items that are over 15a ac combined I'd be interested to see.

What is the output amperage at the inverter for the load power? Is it adjustable?

Must admit the Bluettis are better suited to lazy ppl like me.

Great vid...how's the ambient fan sound on the growwatt? I was planning on replacing and mounting this unit inside my rear-living 35' camping trailer, replacing my hidden TV behind the cabinet area (that raises and lowers), with this unit and put batteries in there too (don't use TV in the living room and lots of room behind cabinet). Was concerned about fan sound, but it will be lowered behind the cabinet most of the time. Any thoughts on that?? Thx!

[@beefitter]

I think putting this inverter in a sleeping location would not be ideal. Also, you do not want to put this inverter in a small closed space. The inverter will generate heat and could shut down or be damaged if it overheats.

[@beefitter]

Also to your other post about utilities. You can program this to run on battery, solar and or utility. The inverter can be programmed to run in any scenario. Utility-Solar-battery. Solar-Battery-Utility. for example. The inverter will run on the first choice then fall back on the second and third choice if one falls below their set parameters.

Question: How long will the Growatt unit retain it's memory configuration without the battery connected? I understand the Growatt has a 30 watt idel consumption, can you setup an external "OFF" switch to conserve battery when traveling?

[@beefitter]

Not sure about how long it will retain the configuration. Call Ian at watts247.com/. He would have that answer. There is a ghost drain on these systems. The best way to live with this, is to buy a bigger battery. I have fortune batteries in this system, and they are very nice and top quality. But what I have is 2.2kw of battery. You may want to consider doubling this size. I have recently purchased 2 -12 volt SOK 206ah Lithium Iron Phosphate batteries. www.sokbattery.com/ This will give me about 5 kw of storage. The batteries are heavy duty and quality made, Both batteries have great metal handles for easy lifting. about 50 lbs each.

[@grumpyshorts1056]

Any reason you can't install a 50a outlet instead of those 110v's and plug in a 5th wheel. I want a 48v setup in the back of my RV to do that, but not sure how it would work. I do realize I can't run the A/C's together and I might be able to run 1 A/C for like 20 minutes, depending on the battery bank and amount of solar. This setup just seems soooo much simpler than all the wiring I see on a lot of RV solar installs.

[@beefitter]

I think for RV use a Victron system would work the best. Two Victron Mutiplus inverters for split phase operation. Victron offers superior systems for the RV industry. They are not cheap, but the build quality is top notch. You would probably be looking at spending $8000.00 on a Victron system.

[@fabiangomez357]

as long as the inverter is large enough, battery bank big enough, solar charge controller having correct volts/amps/watts, could you in theory just park this into an RV and just plug up a mini split a/c system into it and completely bypass tying it into the rv electrical system if you only plan on running a mini split off solar ever?

[@DanielRichards644]

you would need an inverter big enough to fit the surge wattage of the mini-split starting up and wire a plug rated for that much current, but in theory you could do it, probably better off to just wire it into the R/V and run the whole R/V off the solar.

[@kimmer6]

You could do that but you can never have a ''big enough'' battery bank. The problem with battery/inverter operated AC units is that they burn through the watts almost as fast as heaters. IF you have a well insulated RV such that the AC unit cycles on and off or runs reduced loads, you can have an extended run time. You need ample solar panel wattage as well as an MPPT type charge controller with big capacity...say 120 amps, to be able to run the AC during hot sunny times and keep the battery charge level within decent operating range and able to run after dark. I built my son and daughter in law an open frame solar generator on caster wheels to back up their large fridge/freezer and 2 chest freezers. During testing, I ran a 10K BTU 120volt window AC unit with it. In a small bedroom, the run time was 18 hours 20 minutes with the battery drawn down to 20% because its compressor and variable DC fans throttled back and reduced the wattage drastically, setpoint at 72 deg F.. The same unit ran for almost 7 hours and ran the battery down to 8% in my large open beam ceiling living room. It ran wide open at almost 1000 watts the whole time as it was way undersized for the room. You could face the same problem in an RV. The solar generator I built resides under their garage work bench and was meant to be mostly stationary . It weighs 130 pounds. Its 7200 watt hours, 560 amp hours in lithium batteries and runs a 3000 watt pure sine inverter rated for startup overload at 6000 watts for 20 seconds. The 30 amp charge controller is borderline too small but adequate for their occasional use. It also has an onboard 75 amp charger that can run off his Honda 2000 inverter generator. The solar input, generator input and load can all be run simultaneously. I beat on this unit during testing and it ran my Vulcan wire feed welder, air compressor, radial arm saw, right angle grinders, etc. Here's a short video showing it at 2000 watts load charging another battery bank at 150 amps. The batteries can do it for another 3 hours 24 minutes at that load as the meter shows. Yes, yours can be done! kzbin.info/www/bejne/hIrTlK2Ijql5gLM

[@beefitter]

My buddy and I have been doing many scenarios on what is the best way to operate in the fish house. What we finally have agreed to is to using no solar panels. My panels are too heavy to move around. I think it is better to use my inverter setup and have a big battery. If the battery gets depleted we were going to charge it up with our generator. But I think that a 5 kw battery should be able to run and ice house for several days. Then either charge it up with a generator on site or at home on a charger. If your fish house is warm, keeping the battery off the floor should be enough to keep the battery warm. You can't leave the battery in the ice house when there is no heat in the house. The battery would have to go home with you when you leave. When you are transporting the battery, it would have to be in the heated passenger area of your vehicle. David Poz kzbin.info/www/bejne/iYqtY2ifr76GfcU had a real nice Gyll battery that he made a video on. The battery is all one unit, battery cells, BMS and breaker.

[@checkingoutgypsymike2075]

That's a lot of solar panels to get 6 amps in, did it take all 4 to only get 6amps?

[@beefitter]

The growatt can take 80 amps DC. The limiting factor with this inverter is that the max DC voltage is 145 volts DC. That means adding up the Volts open circuit (VOC) to size the solar array. In this case the VOC of each panel is around 45 volts. Adding together 2 panels in series, two panels in parallel adds up to 80 volts VOC. To add four more panels would put you over the 145 volt maximum and could fry the inverter if the DC voltage goes over 145 volts DC. The amperage of these four panels is about 18 amps DC. Well under the max current amperage. But low enough for the two inline fuses to be sized properly. When you are sizing solar panels to an inverter, you need to look at the name plate on the solar panel plus the limits of the inverter. I did make a three part series of how I built this solar generator. Here is part 1: kzbin.info/www/bejne/e2WqdKGre7eSfNU.

[@tcollins11487able]

First time around, I have the same growatt but questioning fusing size. Can you explain how you sized 200a to be adequate for your system along with the 80a breaker. Only difference I have is 200ah instead of your 100ah capacity with the batteries.

[@ekoms108]

Fuse size is (max load) x (1.25) so 125 amp fuse would be the correct size. As far as the breaker goes. He could have used a 100 amp breaker, he's limiting himself to 80 amps in this configuration. Maybe he doesn't plan on using more than 80 amps anyway. The BMS and Inverter/charger has over current protection so you technically don't need fuses or breakers anyway, but the 200 amp fuse isn't a proper saftey feature if all those over current protection should fail because it's oversized. Hope this helps.

[@offgridsolutions2220]

Fantastic build! Are you planning to trailer the panels up to the ice fishing cabin?

[@beefitter]

If you are unfamiliar with a fish house, it is a portable house on wheels that gets pulled out onto a frozen lake. Usually lakes are frozen enough for cars and trucks to safely drive on in Northern MN by mid to late December. Solar panels are too big and heavy. Plus wintertime solar is not the best. I think the solution to this is instead of using solar panels is to get a bigger battery. The batteries can be charged at home. The batteries may last an entire weekend. I do have a generator which can operate the fish house and charge the batteries if needed. The electrical demands on the fish house are quite low. So having 5 kw of battery will go a long way. I did purchase two SOK 206ah batteries for this purpose. The furnace runs of propane. The furnace fan blower is 120v. Lights are LED, so low wattage there. That leaves the television and Directv satellite and a microwave. The microwave runs about 15 to 20 minutes a day. We have a propane stove.

[@offgridsolutions2220]

@@beefitter I see, makes sense. I was curious why you put the panels on the ground, thought maybe it was to make them portable. I am installing a similar system, and am hesitant to put the panels in my roof. Just don’t like the idea of drilling holes in my roof. But ground mount seems expensive and unnecessary considering my roof has good solar exposure. Just curious what you thought process was for the moveable ground mount.

[@beefitter]

@@offgridsolutions2220 Ground mounts in my experience work great. Where I live, snow can cover the solar panels. The snow needs to be removed or the panels will not function. Having panels on a roof can make it challenging to remove the snow. I had solar panels on my garage and pole barn roofs. I can get to the garage panels to remove snow, but the pole barn proved too high to get to. So i moved the solar panels off the pole barn roof and put them on a pole mounted system next to the barn. I do have videos on both systems on my KZbin channel.

@@beefitter really good point, I had not considered snow build up. I’ll watch your solar build video

Oh and you may want to put the battery on the cart first and then the inverter.... should make it a lot easier. 😀

[@beefitter]

Actually this would make it harder. Because I would have to stretch over the battery and it would be hard on my back. The way I do it makes the most sense to me, and works very well.

If you like the handles to go over ruff terrain, upgrade your tires to Pneumatic!

[@angelsuniverse6021]

Wonder why u didnt build.it 48v instead? Awsome.job!

[@beefitter]

At the time I built this, batteries were more expensive than today. Also, I wanted to get the batteries to fit on a two wheel cart. Now batteries are cheaper. I have purchased some SOK batteries for a new setup. I do like the Gyll batteries from signature solar. 5 kw for around $1500. They do weigh 100 lbs per battery, but the battery has a breaker and a BMS.

If you're worried about rough terrain you should have fat air tires.

[@beefitter]

This generator was made for emergency use. Meaning it may have to be moved from place to place. Having air filled tires is another thing that could go wrong and make using the generator much more difficult. Having a flat tire is something I wanted to avoid.

[@jeanstmartin2396]

Great build! Just wondering what the cost was?

[@beefitter]

I have about $2500 tied up into the unit. Solar panel setup was another $750

[@XFBO]

@@beefitter Thanks for sharing the cost!!! I'm needing to build something like this in an outbuilding with no power. Do you think 3k watts is enough to run led lighting in the shop during the day (maybe 1-2 hrs/day) then exterior LED light from dusk to dawn daily and on occasion perhaps a portable table saw, chop saw, etc??? Lastly, does your solar array do a good job replenishing your system back to 100%? How many hours does it take if say they're depleted down to 25%??? Any advice would be appreciated!

[@beefitter]

@@XFBO This system is about 2.4kw. Since I have built this, I have purchased new batteries. I bought 2 - 12v SOK 206ah batteries @ $1029.00 each. This give me about 5 kw of power. 5 kw will give you the power that you are looking for. SOK batteries have their own BMS in the battery case. kzbin.info/www/bejne/iKmweqZmhb2leNk The solar panels put out about 1200 watts of combined power. You should be able to charge a 5kw battery from 20% to 80% in about 4-5 hours of full sun on the panels. The Lithium Iron Phosphate batteries cannot charge if the battery temperature is less than 32 degrees F. If you are using this in cold weather, you need to make the proper steps to protect the battery. SOK batteries BMS does have lo temp protection. Another battery to consider the 24v GY4 or Gyll battery. These are quality made 5 kw battery. Just hook up cables. Around $1500 + shipping. The battery weighs around 100 lbs. kzbin.info/www/bejne/rX6tk5WOhaljgKM. All of these Lithium batteries with proper care and charging will last you 10 to 20 years. That is even if you deplete and charge everyday.

no, it is 120v. I linked this for the system that would work for you. kzbin.info/www/bejne/nJ2teXRrlN6Md8k It will cost you $10,000

How much to make this ?.

[@beefitter]

Since I have made this, technology changes and batteries are cheaper and better. I have made a new solar generator. Easier to make and a bigger battery. I made it the same, on a two wheeler, with a small pallet to hold the batteries. I used a MPP 2724 from watts247.com/product/pip-2724lv-mr/ The 20 amp electric outlets are already on the inverter. I then upgraded the battery to 2 - SOK 12v 206 ah batteries, www.currentconnected.com/product/sok/ wired in series for 24v. The batteries already have a bms in them. So now I have a little over 5kw of power. Twice as much as this build. The new solar generator was easier to build and has more power. I have about $3500 in my new build about the same as this video's solar generator.

My Growatt died after 8 months and support is a nightmare. I’m off grid and I have no refrigerator, lights, AC and support won’t ship a replacement. My neighbor had 2 break in less than a year. DO NOT BUY GROWATT

[@beefitter]

In the USA, I have purchased Growatts from Watts247.com. Ian offers great support. I had a problem with a Growatt under warranty. He shipped me a new one the same day I called him. I had the new inverter in two days.
