I have the exact same system with twin 3.2Kw dual axis trackers which has been functioning flawlessly for the past 6 months. The system produces over 60Kwh daily during the summer months which is enough to not only charge the batteries in less then four hours but also run all my loads.
Really awesome system. I'd love to have the same in my home. One thing though: It's Lithium IRON Phosphate chemistry. Not Lithium ION Phosphate. Not trying to be picky, but it could be confusing to battery chemistry newbies trying to learn.
We have our 6 batteries on our covered patio. In a 120 gallon deck box. Works perfectly. It’s solid and flat to the deck so we ran our cables under deck and drilled a hole into bottom of deck box. Looks great and water proof. $98. Fits 6 perfect.
I have that same inverter and while it performs well as an inverter, the solar controller in it was unreliable and would require the inverter to be disconnected from all power and then reconnect to get it to work. I ended up buying a victron smartsolar and just using that for solar, and only using the inverter as an inverter alone
@@BlueSardex absolutely, ive done the same mostly though some things work well for some and not for others. I had an unreasonable struggle with the growatt vendor here in Australia, but i assume i just got unlucky with the product as well as the vendor, even the replacement they sent appeared to be a refurbished unit, didnt have the tamper seal and was missing buttons, but was also damaged in transit so was returned and i kept the faulty one as the inverter side of it works super well, just the solar part doesnt.
That's incredible. Exactly what I was thinking about building. Can you make another video discussing the panels and other equipment and the costs? I've been looking at similar setups, but it's very difficult to filter the honest brokers from the shysters.
You want 48v 375 & up panel for at least 8kw anything over 10kw will put you in a different tier. If you don't want to spend.10,000 on batteries go with something like Power Queen 👍 200 ah 3 sets of 4 in series & then tie in parallel. The Growatt is fine but there are Inverter's coming out with a lot more programming capabilities which is helpful to setting up option more advance. My mistake was micro Inverters & going grid tie. So now I have both & I'm pulling loads of the grid tie for on all the time when power is lost. Grid tie has build in auto shut down 🤔
nice set up.... only thing I'd say is you didn't need to flip the neg buzz bar... that's what parallel is all about! and the difference on a 200 meter buzz bar "may" make a minor difference but on something that short you'd see no gain! and especially going through such a thick conductor, to see a negatable difference on something that thick you'd probably have to go to a mile or more
That's a very nice setup. I love these rack batteries and there are so many choices on the market now! One thing I'd suggest is getting an HRC fuse (Class T) on the main 4/0 cable :)
I've noticed everyone running the fuses on the battery bank (like you are suggesting) and am curious why you would do this since every one of the batteries has it's own breaker? Is the intention to limit the amps going into the inverter from the entire bank? If this is the case, I assume you would match this fuse to the inverter correct?
@@theclintified There is a good reason to use a class T fuse and it is the amount of current a battery like that can output. The thing is that, if the fuse break, the ark needs to be terminated. And to start an ark with two cable (like in a welder) you need to break the dielectric tension of the air but once the ark is formed the amps will make the ark goes long. So in a fuse or in a breaker the ark is formed in the moment the conductors get separated so you have two amps rates you need to consider: 1 amps to break contact and 2 the max amp that the fuse/breaker can arrest (i dont know the tecnical name). For example a breaker can be 63amps and 10000amps (of ark arreting) and if you put this with a battery that can output more than 10000 amps it will get fire. A Class T is like 200000 amps of breaking amps minimum. So a class T is important to avoid fire if the fuse breaks.
I remember this room. Your channel inspired me to go with 2 Tesla batteries. Im still running them. got them like two years ago. They are still going stong.
@@ModernOffGridDIY its a far cry from where yoi started. Wind turbine, gas generator, batteries with no charge controller. Youve come a loooooong way. Thank you as always for keeping us up to date with your progress!!!!!! 👌
GREAT JOB! An electrical metal trough run horizontal around the room to hide and run all your cables through would provide you the polished professional ESS. AWESOME JOB!
The only thing missing is a 48vDC standby generator that can occasionally start automatically for a short period to charge the batteries on a cloudy day without wind.
Awesome dude! I'm building virtually the same system as you with the same equipment minus the wind turbine. I get a lot of wind in the winter so that might be a good idea for the future.
So nice bro. I've been following you for years. Was excited to see you got this inverter. I bought one for my daughter's off Grid farm back in Nov. We have not stalled it yet. Glad to hear you like it.
Awesome buddy, thanks for the years of support, it's been working Awesome the 12k sure can handle, If you get yours installed you will be rocking and rolling.

Very impressive job. You really had the knowledge and time to achieve this. So no more electric bills. That's absolutely great 👍 You better be celebrating everyday.. You seem to be in the middle of no where? Be safe. Security?? Dogs do a great job..
Love the video. I am researching fully off grid solar for Caribbean land. Building a 2 bed, 2 bath Casita. I want to add in an electric stove rather then gas in case it is rented at times. I am not familiar with this and looking for some guidance before any start.
SO WITH THE LITHIUM BATTERIES WOULD YOU NEED A HEATER IN THE ROOM TO KEEP THE BATTERIES POWERING? I WAS INFORMED IF IT GETS BELOW 20 DEGREES THE BATTERIES WILL NOT HOLD A CHARGE
turbine and midnite classic ? I have similar all in one, with 30kw batteries 1: Is there any communication between inverter and classic ? 2: communication between classic and batteries ? 3: is the only connection the battery leads buster to classic and 1v lower charge voltage set in the classic. Could you just give is some more detail/figures on how you are setting classic to be the slave in this system. Without the communication with batteries would the bms auto turn off ? thanks
A very nice set-up - thanks for sharing!!! I have got the same 12kw Growatt - the wifi dongo has a reset button straight on the light, very bad design and I had just damaged it when resetting 😢.
@@jeanrevolus5571 yes you can but you will lose the visibility (especially when you r offsite) of the solar production from time to time, status of the system eg battery %, statistics, error message, etc
Pirchased exactly the same equipment: GW12k and 6 lifepower, cage. Everything. Two of my batteries are acting up. What cable do have going from the top battery to the inverter and which port does it plug into on the inverter?
On yours how many voc is coming into growatt is it 250 v total with both strings so 125 per string . Your 2 blue wires putting what out from solar voc and watts from panels . Thanks Brian
Is it UL approved and signed off by both the county and utility board. Unless you're not selling back to the grid, if it works and doesn't burn down the place, it should be good. Most approved systems require all the wires inside an electrical chase and rigid conduit along with a master switch to the battery bank that is backed up by a master solenoid and inline fused disconnects. Reference Will Prowse's DIY UL approved photo. Not picking, but having worked for an electrical company and dealing with "A" hole inspectors in California, Arizona and Texas, any "loose" wire/wires are a "no go."
At least where I live, net metering would pay me a small percentage of what I pay for their power. The cost difference between an approved inverter and a decent off-grid inverter is massive. A single approved 12 kw output inverter costs roughly $6K so that I could sell back power, while a pair of 6 kw off-grid inverters cost
Hi there old friend. 12 kw! WOW. NICE. You definitely upgraded! Was wondering what your top 100% charge voltage is going to be? What does the manufacturer recommend that you set it too? You have done an excellent installation of the equipment. I only saw one thing that you might ponder about is outside with your Midnight Solar combiner box where you parallel the output strings to your Growatt system. Every time that you parallel a string of panels you double the current that you have. Your 10 gauge wire, assuming that it is solar wire, just guessing a rough estimate I would say that you are producing a combined current of 35 amps from your Midnite Solar box. Take a clamp on current meter and measure your maximum. You might consider increasing the gauge of wire size from the Midnite solar combiner to your Growatt inverter. I have used 2 gage here to be on the safe side. Everything else that you have done is right on. Well done!
My DIY 132 kWh battery can only be taken to 55.7 maximum, otherwise they great Grade A junk cells from China have a 300 mV differential and go off on OV! Same for the Trophy 220.
Aloha Lou nice to see you again so when you put these batteries togerher with the growatt and set it to LI mode the invertor has preset point to work with the batteries and the BMS in each. there made to work with each other. In the manual it does tell you thos numbers. There is also a another mode but I like the way its been working. it all plays well with each other. I am adding 7,000 of brand new solar panels when i do I have going to be running 8 gauge wire which is what the inverter recommends. I checked the wire when I installed them and its all good for now until I change the to 7,000 watts. I will be install another system just like this one on my moms off grid system in 4 weeks just smaller 2 batteries 6k Growatt and 4k solar for her. I will also be adding even more eg4 batteries to mine system in a few months. I own another home that has a grid tie system never did show it on the channel yet buy I will be installing 7k of solar on it and new inverters so lots of projects lol. Toworrow I will be installing wood fence at my other home. I hope you been well and stay out of truoble lol.
Remember the VOC voltage is what you are adding up. I have 440 watt panels with 49.61 VOC meaning I can connect 8 panels to my Growatt 5000es that accepts 450 volts and can be paralleled.
@@ModernOffGridDIY Thanks for the reply. I know you said you purchased from Signature Solar. I looked at the page and there were quite a few things to browse. But a specific list of what you have built, I believe would hwlp out more folks as well in saving some time. Thanks again.
I'm trying to figure out how I can move my house to solar with battery power, but I don't know how much I would need. I'm in the north east of the US and have central air. How much solar and battery would I need to power my whole house and eliminate my electric bill? I've seen this kit you have along with panels, but I'm not sure if it would be enough. I think I'd need to generate about 6000 watts per day to power everything.
I kind of would a setup, will have grid power alongside, this is only to power low wattage appliances, AC's, Heaters, Fridge, pumps would be on Grid power. 4 solar panels, each of 150W, from left to right, top to bottom, we'll have 4, so 16 panels, 48V system. Would I need two or one charge controller for this said setup? And, can we only use 4 of those rack mounted batteries? And finally a single 10kW inverter, 240V system as this is on a 240 country
Awesome just remember there is alot of options out there to consider. Keep shopping around and you will see lots. I might consider installing a solark inverter on my next property build out.
WOW!! (for ME and what I see....) This is the MOST put together system on TH-cam! You've done an EXCELLENT job with putting this all together. As I realize Growatt is making it a lot easier as time goes by. This is astonishing!!! Is there a place that I can go and see your price list to see how much ($$$$) all this is? I understand it's MANY thousands of dollars but I'd like to see the component specs also. THANK YOU for posting this!!!!!!! I now know my dream IS reachable!!!! .... AND, I'm in Arizona where the sun never stops shining bright.
Awesome and thanks for your support, it cost a little over 12k the specs and manuals for the 48v eg4 batteries and 12k growatt inverter can be found on there website.
nice setup...would like to see your solar panel stand you built...is it stable and can you adjust angle? seems like you only have the panels mounted on one spot in the middle...are those fence posts you're using?
Nice set up! I think it’s way overkill considering you live in Hawaii. I live in Seattle and I only have 7.5 kW of solar and 9.6 kW of battery power. Works for me. 🖖
I'm about to add on 7,000 watts of brand new solar panels in the next couple weeks. I planning on adding AC units and a jacuzzi to the System. Always better to have more then less when it comes to power. Thanks for sharing glad your System is working for you.
Great job presenting the system !! Would like to know more about house size and components in the home i.e. HVAC system. Square ft home, size of family? are you completely off grid and the altitude. It appears you are on a hillside. Love to see it on google earth. Thanks for the education
Great viideo, I would love to hear how the inverter is doing in a couple of years from now, I'm looking into the Luxpower 12000 watt all in one which is make by one of the same engineer's as Growwatt.
do you have any info regarding why having the negative lead at the bottom of the bus bar would be in anyway different to having it at the top? I do not think it makes any difference whatsoever
@@douglasbeal3647 Since the top and bottom are electrically connected with a bus bar across all the negative terminals how does connecting at one end of the bar rather than the other, or the middle, matter? The only reason to stagger the connections like that is if you aren't using a bus bar.
@@JRP3 I'm not an electrician, only have seen other videos in my own research that show the top batteries charging at a slightly higher rate than the bottom ones.
That is an awesome system and it looks like you can basically run everything you need to be completely off-grid. I wish there was a way you could help me set this up and I was wondering how much the cost is for the solar panels and how many more solar panels can you add to the system that you have there. We want to do this in our home and I'm just wondering if you could assist us that would be really awesome I am a builder and I would love to put this in all of our homes because the homes and building are off-grid homes. Awesome video brother thank you hope to hear from you
@@theunboxnetwork Thank you for the reply and that seems very affordable considering the benefits in the long run. I think a complete system that would run everything would be ideal especially with a battery back up system that even has a generator to assist the batteries when they drop below 50%
@@theunboxnetwork I found the box, batteries and inverter for $5600 but that is only two batteries. I want to hit the purchase button but then I’m thinking what if I’m missing something.. Did you find it for all 5 batteries?
So it's possible to connect multiple chargers to batteries like this? What if you also have a generator or some hydro? Do they all just have to match voltage? How does this work with the inverter/charger?
Wind Turbine charge controller is set 1 volt below the growatt solar set points that way at no time will the wind Turbine put to much power in and the factory growatt is the master and the bms still works.
So I use 32kWh a day average. I live in NH. How much of a system do I have to build out to power the whole house? I love this new technology, I just wish I could better understand all these numbers. Set up looks great
awesome! i also have a growatt inverter and a 48v lithium battery bank. i'm looking in to wind turbines for the moment. so you just connect the charge controller to the batterys? the growatt inverter does not do weird things when there is coming power from the charge controller. i can imagine for the battery to charge, the voltage from the charge controller is higher then the voltage off the battery. so the inverter reads the higher voltage so it thinks the battery is more charged than it actually is?
Do the Growatts have a phase imbalance limit? I picked up 2 lifepower4 batteries and a single eg4 6500 inverter to start out. Yes, only single phase 120 but I do plan on eventually getting two inverters for 240. So easy to set up now. Excellent power plant!!!
I have the same setup minus the wind stuff. I dont run hot water heater, stove, dryer. Are you able to run all that? Do you run only those appliances one at a time? When i had all mine hooked up, it seemed like more than i was comfortable with.
Excellent video and want to build this myself. Do you have a list of all the components published? I looked in your comments/description and see a general idea but not a specific list. Thank you!
Not much really led lights though out the house, Electric hot water I heat in the day time, tvs, wifi, charge phones, charge milwaukee battery for my tools, I have 2 freezers and 1 full size refrigerator, I use about 25% of my battery storage each night then fully charged by 10am
do any of the government programs for solar help out with the cost of any of this? Like when you call Sunpower or Zolernet and they say the federal program will pay 25%
Because the I'm adding another string of solar panels. Plus I think the voltage swing from the wind Turbine would be to much and dont want to take a chance.

Same system I'm hoping toget soon as I can get the money together. I live just a hour from Signature Solar. Been there once and got a couple things.
Cool man. Remember it's not a rush save money and slowly get things you need. Their are other brand out there that might work for you to.
@@ModernOffGridDIY Any suggestions, would definitely take a look. Thanks
One more question, how many panels would it take to fill those batteries with Solar energy?
Nice system man, I'm Jealous. Been watching your videos since u began filming. another awesome vid.
I appreciate that! Glad you like the content. Thanks buddy
That’s some mad skills bro!!! Nice!!
Thanks
Great video of your solar system. I really like how you set it up.
Nice work. My friend David Poz loves those. One day I will buy them to replace my 15 KWH setup.. God Bless
System is running Awesome. Batteries are doing crate. Thanks hope you been well
Clear explanation. Thanks for excellent video. Have you tried to run the system that can handle 3 ton HVAC heat pump over night without problems?
Where my off grid home is located Air conditioning is not needed
I like that you integrated wind power.
👍
What is maximum amperage output to breaker box does inverter give?
Is that a low frequency or high frequency inverter?
Will the Growatt inverter do AC coupling? and will it frequency shift?
I'm trying to figure out how I can move my house to solar with battery power, but I don't know how much I would need. I'm in the north east of the US and have central air. How much solar and battery would I need to power my whole house and eliminate my electric bill? I've seen this kit you have along with panels, but I'm not sure if it would be enough. I think I'd need to generate about 6000 watts per day to power everything.
I kind of would a setup, will have grid power alongside, this is only to power low wattage appliances, AC's, Heaters, Fridge, pumps would be on Grid power.
4 solar panels, each of 150W, from left to right,
top to bottom, we'll have 4, so 16 panels, 48V system.
Would I need two or one charge controller for this said setup? And, can we only use 4 of those rack mounted batteries?
And finally a single 10kW inverter, 240V system as this is on a 240 country
What if there is only 1 phase at home, how do you install this growth inverter?
Great 👍👍👍 videos
Looking forward to a 1 year update on the Growatts...
Did you add a ground rod to the inverter being off grid...
I already had 4 ground rods from when I had the system before this one. Update will be coming soon.
I’m gonna build my off grid home this summer , I’m gonna get that system
Awesome just remember there is alot of options out there to consider. Keep shopping around and you will see lots. I might consider installing a solark inverter on my next property build out.
WOW!! (for ME and what I see....) This is the MOST put together system on TH-cam! You've done an EXCELLENT job with putting this all together. As I realize Growatt is making it a lot easier as time goes by. This is astonishing!!! Is there a place that I can go and see your price list to see how much ($$$$) all this is? I understand it's MANY thousands of dollars but I'd like to see the component specs also. THANK YOU for posting this!!!!!!! I now know my dream IS reachable!!!! .... AND, I'm in Arizona where the sun never stops shining bright.
Awesome and thanks for your support, it cost a little over 12k the specs and manuals for the 48v eg4 batteries and 12k growatt inverter can be found on there website.
Good job. exactly the setup I have been planning to do. My local electric is only 13 cents / kw Canadian so haven't been able to justify it yet
nice setup...would like to see your solar panel stand you built...is it stable and can you adjust angle? seems like you only have the panels mounted on one spot in the middle...are those fence posts you're using?
Thanks. I have videos building this setup check out my other videos I also go over the materials.
You don’t have to buy transformer for two units to run 240. EG4 and MPP has a split phase setup, only have to add communication wire between the two.
This needs to be higher.
Nice set up! I think it’s way overkill considering you live in Hawaii. I live in Seattle and I only have 7.5 kW of solar and 9.6 kW of battery power.
Works for me. 🖖
I'm about to add on 7,000 watts of brand new solar panels in the next couple weeks. I planning on adding AC units and a jacuzzi to the System. Always better to have more then less when it comes to power. Thanks for sharing glad your System is working for you.
@@ModernOffGridDIY
As long as you can afford it! 🤙
Great job presenting the system !! Would like to know more about house size and components in the home i.e. HVAC system. Square ft home, size of family? are you completely off grid and the altitude. It appears you are on a hillside. Love to see it on google earth. Thanks for the education
Quantifying your energy usage would be very helpful to gauge energy requirements of your domicile. Enjoyed your enthusiasm!
Great video. Can you show a video how you got your wind turbines setup. How to install. Thanks
I have other videos showing how my wind Turbine is hooked up
Great viideo, I would love to hear how the inverter is doing in a couple of years from now, I'm looking into the Luxpower 12000 watt all in one which is make by one of the same engineer's as Growwatt.
Sounds good!
Hello, I have 6kw growatt my solar input not showing up or in the screen..what so I need to do to see my solar panel on the screen..thank you
Been looking to do this but with a pair of EG6500xe inverters in split phase
do you have any info regarding why having the negative lead at the bottom of the bus bar would be in anyway different to having it at the top? I do not think it makes any difference whatsoever
I was going to make the same comment since he's using a bus bar. It would matter more if he didn't have the bus bar.
Charges the batteries equally versus from top to bottom
@@douglasbeal3647 Since the top and bottom are electrically connected with a bus bar across all the negative terminals how does connecting at one end of the bar rather than the other, or the middle, matter? The only reason to stagger the connections like that is if you aren't using a bus bar.
@@JRP3 I'm not an electrician, only have seen other videos in my own research that show the top batteries charging at a slightly higher rate than the bottom ones.
@@douglasbeal3647 Were those setups using bus bars?
That is an awesome system and it looks like you can basically run everything you need to be completely off-grid. I wish there was a way you could help me set this up and I was wondering how much the cost is for the solar panels and how many more solar panels can you add to the system that you have there. We want to do this in our home and I'm just wondering if you could assist us that would be really awesome I am a builder and I would love to put this in all of our homes because the homes and building are off-grid homes. Awesome video brother thank you hope to hear from you
I had checked this system out and it costs about $5k to $10k
@@theunboxnetwork Thank you for the reply and that seems very affordable considering the benefits in the long run. I think a complete system that would run everything would be ideal especially with a battery back up system that even has a generator to assist the batteries when they drop below 50%
@@theunboxnetwork I found the box, batteries and inverter for $5600 but that is only two batteries. I want to hit the purchase button but then I’m thinking what if I’m missing something.. Did you find it for all 5 batteries?
I live in Hawaii too. Can I ask how shipping all this to Hawaii was with Signature Solar?
So it's possible to connect multiple chargers to batteries like this? What if you also have a generator or some hydro? Do they all just have to match voltage? How does this work with the inverter/charger?
how did you configure the midnite charge controller to connect with the whole system
Wind Turbine charge controller is set 1 volt below the growatt solar set points that way at no time will the wind Turbine put to much power in and the factory growatt is the master and the bms still works.
Beautiful, I am installing a 12kw unit now for a customer. Will be soon upgrading the batteries to yhe LIFEPOWER batteries and rack.
Cool man
Thanks, my patience was running out, glad you are up and running keep on keeping on, good work
Enjoy
So I use 32kWh a day average.
I live in NH.
How much of a system do I have to build out to power the whole house?
I love this new technology, I just wish I could better understand all these numbers.
Set up looks great
awesome! i also have a growatt inverter and a 48v lithium battery bank. i'm looking in to wind turbines for the moment. so you just connect the charge controller to the batterys? the growatt inverter does not do weird things when there is coming power from the charge controller. i can imagine for the battery to charge, the voltage from the charge controller is higher then the voltage off the battery. so the inverter reads the higher voltage so it thinks the battery is more charged than it actually is?
Do the Growatts have a phase imbalance limit? I picked up 2 lifepower4 batteries and a single eg4 6500 inverter to start out. Yes, only single phase 120 but I do plan on eventually getting two inverters for 240. So easy to set up now. Excellent power plant!!!
Is it's not balanced if you run 2 120v units you have to buy the auto transformer to make it work. Thanks for the support
So when the fan burns out you have a plan? Do you have a replacement fan?
Do you have Air Conditioning or a clothes dryer in your home
I have washer and dryer and dish washer and Electric water heater, I have a split AC being installed soon.
What does the bridge rectify do?
I have the same setup minus the wind stuff. I dont run hot water heater, stove, dryer. Are you able to run all that? Do you run only those appliances one at a time? When i had all mine hooked up, it seemed like more than i was comfortable with.
Is there a regular service charge for live monitoring via the app? Can it be used without the app? Looks clean🤙
Yes
Excellent video and want to build this myself. Do you have a list of all the components published? I looked in your comments/description and see a general idea but not a specific list. Thank you!
Inverter uotuptut would be connected to house main panel .. How do you avoid that Power is not returning to the national grid?
It's off grid and there is no national grid
New to this stuff. Could you not add the wind turbine power direct to the combiner bank or is there some technical reason not to?
What is the total yearly kw average this system will make. I use 40kw a year. And want to go solar.
Great work. What are your evening electrical loads?
Not much really led lights though out the house, Electric hot water I heat in the day time, tvs, wifi, charge phones, charge milwaukee battery for my tools, I have 2 freezers and 1 full size refrigerator, I use about 25% of my battery storage each night then fully charged by 10am
do any of the government programs for solar help out with the cost of any of this? Like when you call Sunpower or Zolernet and they say the federal program will pay 25%
Is there any way to get the inverter and the other wall mounted pieces of equipment into the rack too ?
Is the white cable from the top battery to the inverter an rs 485 cable or a read write cable?
Just a communication cable just different color
Wow Awesome upgrade
I just upgraded to Lifepo4 too 28 kwh
Nice buddy 👍
i looking to get grid tie any brand inverter with will suppory those lifelipo4 batteries, any sugestions? thanks!
Excellent video and really got me seriously considering starting out with solar installation at home. Lovely clear explanations.
I'm glad it was helpful good luck on your project.
If you only had one string of pv panels, could you just connect the wind turbine dc into the second string input of the inverter/charge controller?
No because the voltage swing would be to much.
Why did you not use the second solar input for the wind power (after rectifier). That way you can track all of your incoming power in one interface?
Because the I'm adding another string of solar panels. Plus I think the voltage swing from the wind Turbine would be to much and dont want to take a chance.
