That's really sweet! I have been looking at this unit as well. I was initially thinking about two of the 120v 5-6kw systems running together to get the 240v, but this is much simpler.

Remember how energy flows. Even at #6 wire THHN lets say - that will allow energy flow to75 amp indefinitely. A surge of 36000 will theoretically never happen and can be protected against with fuses, etc. 12000w is a VERY large load and while possible, most unlikely. I had to work hard just to get a 12000w load running to test my inverter. #6 wire will run that surge for 10 minutes before heating up to dangerous levels. Your BMS will sense that load and properly manage disconnection if it gets out of spec way before that wire burns. Make sure you are using good BMS systems - I use Daly and they have been very effective to date.
I agree with both of you. I would probably put in a heavier wire for just in case. With that being said each person knows what his home is drawing for a power load.

Great video Nubian How many watts power solar do you recommend to best perform/run on this unit. I’ve recently bought a battery Bank of 26.4KW -48 V 550AH (6 V cells ) I currently looking at a Growatt 12k We’re currently consuming an average of 24k per day.

Lead carbon batteries, from my recherche they’ve a high cyclic life of 7000 cycles (30% depth of discharge), extended lifespan of up to 20 years, and resistance to sulfation. These are some of the best off grid batteries available in the Australian market to date.
@@lizaramos412 you must parallel the 2 banks. Positive to Positive and negative to negative of the 2 banks to a bus bar then feed the inverter from the bus bar
@@nubiandavis2610 What I heard from the Dyness manufacturer is that mixing different chemistry can damage the Lithium batteries and mixing different old and new batteries could affect batteries life.
I didn't see the primary solar array output on the inverter.... I looked into a system like this and the cost is prohibitive in Thailand. Ample sun, cells are cheap, inverters are cheap here (as they are made in country) but LiPos are crazy expensive as they are not made in country and face a HUGE VAT tax.
The screen is a toggle per page so you must cycle through to get to the information that you want. Too bad about Lifepo4, they are what you will need primarily
Is the 2nd MPPT Charge Controller (Outback?) wired in to the Growatt? I saw that it was possible and I see it on your LCD, but didn't see anything in the manual on how it would be done. Thanks
@@nubiandavis2610 then mine is definitely defective. The thing is it turns right back on and you don’t even notice it. Unless you have an energy monitor. And you can see it in the run time history.
@@Engraveyourgift If you got it from Signature Solar, call support and tell them you need a replacement system board. It is a very easy swap and you will get the new model of it that has the ability to read grid consumption. The original board did not do this. I received an upgraded board from Growatt direct in China a while back but all of the new ones they send out to therir distributers is the newer model.
@@nubiandavis2610 yes I did buy from Signature Sola. But for me the customer service has been a nightmare. And I do not trust that company at all. Thank you for the tip.
I suppose you can however the Growatt platform is a off grid solution therefore it does not have the logic to work in that fashion. My Outback Radian 8048A could do that. I know the Solark can. The issue is the Solark and Outback systems cost twice as much as the Growatt 12k. Just not worth it to me. I can craft how many panels I need and how much battery storage I require to run solar days / batteries night. That is exactly what I set this up to do. I do wish Growatt had 10kw of solar input and not limit it to 7kw, that would have been a plus.

As for our sunny islands, I wanted to grab a spare recently and the price is back up high again... wish I would have gotten more when they were $1200 on ebay. They are the Cadillac of inverters.... lots of over load capacity and very low idle current.
According to the spec sheet, you can’t parallel these. However the 5k model can be paralleled up to 6 units. You may also need a transformer for 120/240 as the 5k does not have this built in.
I'm liking most things about this, except that it's so dang noisy I'd need a spare room just to keep the noise away. I live in LA, and I can't afford an extra 200k of house just to have a place for the inverter.
Subscribed to ya . The Growatt LF inverter is sure a beast when it comes to running almost every heavy loads in the whole house . We DIY preppers are #1 when we depend on power , quality and efficiency in our system at this time & age when it is needed during any outages or to save on the light bill at will . When you get a chance , check out my solar videos , hit like , leave a message and subscribe . May the solar be with you .
READ THIS !!!! I bought this inverter because I wanted to generate solar power, using this solar power and feed in additional grid power at the same time whenever solar isnt enough. I wanted to use the battery power only for grid outages OR, eventually use battery power during a few hours per day, when our utility company charges higher rates during peak hours. This inverter cant do this, even the seller told me it would do this! Issues i had in detail: No 1: Inverter cant provide solar and grid source simultaneously Either if setting Menu 1 is SOL or SBU, the inverter is always using battery power when solar isnt enough, until the battery reaches its low voltage setting from menu 12. That means throughout the day the inverter is hundred of times tapping into the battery, back and forth switching. This wears on the battery and the internal relay. No 2: PV charging current is always wrong ( display " Input PV A") This value is always wrong. For example I could prove with Amp clamp/Voltmeter a production at the moment of 1,6kw, the PV Voltage stated 130 Volt and PV charging current stated 32Amp. This turns out to be almost twice as much as my panels are rated for. No 3: Wrong display information PV charging power ( "PV Batt kw") is actually NOT the charge power. It is indeed the actual solar production and this number is way off of what is described under No 2. The actual charge power is always way less, proven by Voltmeter and Ampclamp. PV charging power is actually production, proven by Voltmeter and Ampclamp. No 4: Solar production limited For a long time I scratched my head why this system isnt producing what it should. the battery is constantly making up for the difference to supply the load. Then i found out that" PV charging power" is actually production in watt and was LIMITED by the inverter: It makes no sense at all that the actual production drawn from the panels is reduced by setting Menu 2. Menu 2 supposed to limit the maximum charge current (as per manual), to protect the battery of getting overworked or hot. Menu 2 should be totally independent from the actual production, every single watt not going into the battery should be available for the loads. As soon as I changed setting menu 2 from 30 to 100 the production went up, and what I measured with voltmeter and ampclamp was indeed matching PV Batt W, which want to be a "charge power". No 5: In regards to a question to Error 61 I was sent information on how to calibrate the voltage measuring feature. No I wont do it, thats something a manufacturer has to do, thats not the customers job. No 6: No clean solar cut in/out When solar production reaches its threshold the build in charger should read the low Amps and cut in or out one single time. Instead the charger toggles maybe 20 or 30 times on and off until solar is clearly beyond the treshold. this doesnt make sense at wears out relays or switches. Seller and user manual cant describe owner what menu 26 is for.... If there is never enough solar power for the loads the inverteris wearing out batteries prematurely. Settings dont make sense and work counter productive. Values given in the displays are wrong. The user manual is misleading and lacks a lot of explanation.
It is a 12000w low frequency high power inverter. It is not meant to be quiet, it is meant to power loads 24/7 with 89% efficiency. Put it in a outbuilding.

Daly 200a smart bms (2) 4/0 cabling. Upgrading BMS to three (3) Seplus 200a units to run 3 separate 15ah banks paralleled for 45 kw of storage. Might add one more 15kw bank bringing the total to 60 kwh.
Could you share your settings in the growatt server and breaker wiring? Thank you
Settings will be specific to your battery bank, etc. I use lifepo4 75 kwh so I charge to 58.4 and down to 46v before back to grid.
Wiring, follow your loads. I have my system prepared to run 12kw loads so I size accordingly. 4/0 battery cable, #8 50a for AC
@@nubiandavis2610 Thank you for the reply, I built two 4p16s 48v and running 12kw growatt. I'm done with one side of panels and ready to flip the breaks for pv and batteries. I kept finding resources that said float was needed. I was wanting to do 80% 53.20 discharge 20% 51.20. But was not sure of the settings that I should use.
@@krom6017 those settings are very conservative and will save your battery life, probably extending it to over 20 years. I'm a Believer and getting max out of batteries therefore I'll run them all the way up to 58.4 and all the way down to 44 volts I mean the difference is 15 years versus 20
@@nubiandavis2610 The issue I'm having is the manual and voltage settings correct. postimg.cc/NLXRGK5Q Does not show neutral being hooked up but I have see pictures where neutral is connected. I have the growatt set to 240v but have not load tested yet as the manual is not every explicit about it.
I have a question on ERROR messages. You are scrolling the menu and at 2:59 minutes there is 511 with a 810 and then to the right is 01 .. what is this error message mean? I have one of these inverters and even upon turn on stone cold I get this error. Now my point is that Signature Solar told me the error was that my inverter was 196F ... impossible however. The day was only 57F degrees and I just turned it on and this error was there. What do you think?
How's it handling your AC unit and what size? I have 4 ton, which the vendor claims the inverter can handle fine. I have the same goal to power all my loads.
It handles any load, period. 5 ton AND a 3 ton. Never breaks a sweat.
You can add a soft start kit too if it's too many amps. I dropped from 65 amp start to 25 amp on start up on a 3.5 ton. 13.5 amps running, 240v.
How do you tolerate that fan noise. My neighbors and me are having a terrible time with the noise. How to control it.
I have an external 4 car building that I use for my equipment so we never hear it
Where can I buy this 12 kw inverter. I live in South Africa

Great video Nubian
How many watts power solar do you recommend to best perform/run on this unit.
I’ve recently bought a battery Bank of 26.4KW -48 V 550AH (6 V cells )
I currently looking at a Growatt 12k
We’re currently consuming an average of 24k per day.
Your video is extremely helpful for anyone who’s wanting to back themselves up from the gridd.
Excellent start. Those 6v cells are they lead acid or lithium? Welcome to the channel!!
@@nubiandavis2610 thanks for your prompt reply.
Lead carbon batteries, from my recherche they’ve a high cyclic life of 7000 cycles (30% depth of discharge), extended lifespan of up to 20 years, and resistance to sulfation. These are some of the best off grid batteries available in the Australian market to date.
@@sebastienstephanno6814 that is excellent. I remember Outback Power making such batteries a few years ago
How do you add LiFePo4 batteries later without damaging their DOD or life cycle?
Create a new 16s bank and add away. All my cells are pretty new so it will not pose any issue
@@nubiandavis2610 I have bought the same inverter, Growatt 12kW. Could you please be more specific on how I should connect a second battery bank?
@@lizaramos412 you must parallel the 2 banks. Positive to Positive and negative to negative of the 2 banks to a bus bar then feed the inverter from the bus bar
@@nubiandavis2610 What I heard from the Dyness manufacturer is that mixing different chemistry can damage the Lithium batteries and mixing different old and new batteries could affect batteries life.
@@nubiandavis2610 I will follow your setup, will look for the bus bar here in Paraguay, which is a little more difficult than in the US :)
I didn't see the primary solar array output on the inverter.... I looked into a system like this and the cost is prohibitive in Thailand. Ample sun, cells are cheap, inverters are cheap here (as they are made in country) but LiPos are crazy expensive as they are not made in country and face a HUGE VAT tax.
The screen is a toggle per page so you must cycle through to get to the information that you want. Too bad about Lifepo4, they are what you will need primarily
looking good
thanks!! I cannot believe what this thing can handle. I have not seen load handling like this since my Outback Radian 8048a
However isn't this inverter only take in 150vdc how did you get the array to carry that 5kw load
250v dc
Believe it!
Yessir!!
Is the 2nd MPPT Charge Controller (Outback?) wired in to the Growatt? I saw that it was possible and I see it on your LCD, but didn't see anything in the manual on how it would be done. Thanks
No, the outback goes directly to the bus bars to feed the batteries. The Growatt has 2 of it's own mppt controllers 60a each 120 total (7000 watts)
This is nice
i like Growatt
A few bugs but they can power loads. That's the long and short of it
Good stuff. Solar is FUN, isn't it :)
Indeed it is!! And addicting
2 huge transformers
Dos your inverter turn off randomly during a weak of operation?
No it is always on 24/7
@@nubiandavis2610 then mine is definitely defective. The thing is it turns right back on and you don’t even notice it. Unless you have an energy monitor. And you can see it in the run time history.
@@Engraveyourgift If you got it from Signature Solar, call support and tell them you need a replacement system board. It is a very easy swap and you will get the new model of it that has the ability to read grid consumption. The original board did not do this. I received an upgraded board from Growatt direct in China a while back but all of the new ones they send out to therir distributers is the newer model.
@@nubiandavis2610 yes I did buy from Signature Sola. But for me the customer service has been a nightmare. And I do not trust that company at all. Thank you for the tip.
@@Engraveyourgift give them another chance, they are pretty good.
Can you use ac coupling ??
I suppose you can however the Growatt platform is a off grid solution therefore it does not have the logic to work in that fashion. My Outback Radian 8048A could do that. I know the Solark can. The issue is the Solark and Outback systems cost twice as much as the Growatt 12k. Just not worth it to me. I can craft how many panels I need and how much battery storage I require to run solar days / batteries night. That is exactly what I set this up to do. I do wish Growatt had 10kw of solar input and not limit it to 7kw, that would have been a plus.
@@nubiandavis2610 I see, I have an existing 2.6. Kw powering a Sma sunny boy grid tie with another 2.5 going to a 18kw battery (Chevy volt battery)that I am using a 1.7kva ups to run my house at night. And that works perfect but my day grid solar goes out and I don’t get compensated for it. I have an growatt and another 22kw of lifepo4. I just didn’t want to waste that system and buy another mppt charger and rewrite my solar for the lower volt charger. I know there is 600v but it’s just to much right now.
Thanks

Hi, what's the maximum PV voltage that this Inverter handles? - I Read the specifications and it said 150VDC, is there any problem with the 176VDC of your video ?

What is the 48v idle current on that inverter?
Honestly, for my use case it is never idle. I can try and find out for you.
@@nubiandavis2610 Thanks so much! I'm very curious. I have a pair of sunny islands that make 12kw and they draw 1.2amps @ 48v at idle. That's remarkably low so I'd love to compare. Hey do you have a video on your battery?
@@ai4px those SI units are very efficient. I wanted to actually get a pair when they were all over last year but never did. This is a working unit and gets absolutely zero downtime. Check my videos, I am sure I detail my battery somewhere.
@@nubiandavis2610 Ok, thanks... I've been watching a lot of your stuff today. Great info. As for our sunny islands, I wanted to grab a spare recently and the price is back up high again... wish I would have gotten more when they were $1200 on ebay. They are the Cadillac of inverters.... lots of over load capacity and very low idle current.
@@ai4px yes definitely at 1200. Not at what they cost now. Easier to get a 12kw Growatt
Where did u buy this and can I parallel x2 12kw together for a total of 24 kw system ?
According to the spec sheet, you can’t parallel these. However the 5k model can be paralleled up to 6 units. You may also need a transformer for 120/240 as the 5k does not have this built in.
I'm liking most things about this, except that it's so dang noisy I'd need a spare room just to keep the noise away. I live in LA, and I can't afford an extra 200k of house just to have a place for the inverter.
Its true, very loud fans to move that heat away. Most put it in the garage
Stick it in the garage man
Subscribed to ya . The Growatt LF inverter is sure a beast when it comes to running almost every heavy loads in the whole house .

I certainly will
So how long have you ran it at 12k output continuously ?

Cool 😎
wery nice
Now my fans activate every 5 minutes when in solar.
They are nice but fan runs all the time on our s
READ THIS !!!!
I bought this inverter because I wanted to generate solar power, using this solar power and feed in additional grid power at the same time whenever solar isnt enough. I wanted to use the battery power only for grid outages OR, eventually use battery power during a few hours per day, when our utility company charges higher rates during peak hours. This inverter cant do this, even the seller told me it would do this!
Issues i had in detail:
No 1: Inverter cant provide solar and grid source simultaneously
Either if setting Menu 1 is SOL or SBU, the inverter is always using battery power when solar isnt enough, until the battery reaches its low voltage setting from menu 12. That means throughout the day the inverter is hundred of times tapping into the battery, back and forth switching. This wears on the battery and the internal relay.
No 2: PV charging current is always wrong ( display " Input PV A")
This value is always wrong. For example I could prove with Amp clamp/Voltmeter a production at the moment of 1,6kw, the PV Voltage stated 130 Volt and PV charging current stated 32Amp. This turns out to be almost twice as much as my panels are rated for.
No 3: Wrong display information
PV charging power ( "PV Batt kw") is actually NOT the charge power. It is indeed the actual solar production and this number is way off of what is described under No 2.
The actual charge power is always way less, proven by Voltmeter and Ampclamp. PV charging power is actually production, proven by Voltmeter and Ampclamp.
No 4: Solar production limited
For a long time I scratched my head why this system isnt producing what it should. the battery is constantly making up for the difference to supply the load. Then i found out that" PV charging power" is actually production in watt and was LIMITED by the inverter: It makes no sense at all that the actual production drawn from the panels is reduced by setting Menu 2. Menu 2 supposed to limit the maximum charge current (as per manual), to protect the battery of getting overworked or hot. Menu 2 should be totally independent from the actual production, every single watt not going into the battery should be available for the loads.
As soon as I changed setting menu 2 from 30 to 100 the production went up, and what I measured with voltmeter and ampclamp was indeed matching PV Batt W, which want to be a "charge power".
No 5: In regards to a question to Error 61 I was sent information on how to calibrate the voltage measuring feature. No I wont do it, thats something a manufacturer has to do, thats not the customers job.
No 6: No clean solar cut in/out
When solar production reaches its threshold the build in charger should read the low Amps and cut in or out one single time. Instead the charger toggles maybe 20 or 30 times on and off until solar is clearly beyond the treshold. this doesnt make sense at wears out relays or switches.
Seller and user manual cant describe owner what menu 26 is for....
If there is never enough solar power for the loads the inverteris wearing out batteries prematurely. Settings dont make sense and work counter productive. Values given in the displays are wrong. The user manual is misleading and lacks a lot of explanation.
man that's very noisy
It is a 12000w low frequency high power inverter. It is not meant to be quiet, it is meant to power loads 24/7 with 89% efficiency. Put it in a outbuilding.
Quite noisy

Speak for your own sins buster,
The most of us are managing not to be shits to each other without an omnipresent overseer.
It can only handle 9k of solar and cannot be paralleled, not a beast. The Sol-Ark runs all over this
I would imagine the sol ark should run all over this thing that it cost twice as much.
@@nubiandavis2610 Did you know Growatt software allows them full access to your system, they can even turn it off?
I have been watching them for the past year, how much control do people want to give away.
At 3-4 times the price. And the sol-ark will NOT produce 12 KWh continously. Deceptive marketing on their part which is too bad. I like their products but I will not pay top dollar for a product advertised as 12 KWh when in reality it is only 9 KWh.
That equates to a lie in my book.
This is only for rich people who don't know what to do with their money. I can build one with less than 50 grand.
I would hope so.
I have some issues to understand the manual and display. Is there a way you would support me? Email or text/ call? Would highly appreciate it!
