Got 10kw of batteries just to keep my gas furnace going for a few days if Grid goes down, but could add another of them Growatt and got another 1kw on panels I could add to charge a car with 240v if this 2kw system pans out and find an EV that does not cost a small house.
Please consider building bus-bars instead of daisy-chaining your batteries. You have built a really good system but your long term battery capacity will be negatively impacted by not using bus-bars. Since each battery has it's own BMS, a weaker battery will disconnect from the bus-bar independently from the other batteries without shutting down the whole parallel group. Similarly, when charging, the strongest (largest capacity) battery will continue to charge even when the slightly lower capacity batteries have reached full charge. Overall your battery bank will have higher capacity and be better balanced over time. Your system is impressive. I also use the Growatts (5000ES-US) with an autotransformer for 240/120.
I agree that’s on the agenda for next week lol , at the lower C ratings it’s okay the way I’m doing it now but when I start pulling 50 amps at 240 volts I’ll need those buss bars, I’m going to add a 4th inverter and wire it in split phase . Add 1/0 AGW wires from the inverters buss bars to the battery buss bars !!! Good eye !! Currently I’m using 3000 watts max in single phase so the C load isn’t much but now that I have 30 panel the C load for charging is pretty high! I thought about that the day i finished the panels lol
Nice setup. I've got to 2, 2000 watt systems - a Bluetti that's running on a four circuit transfer switch, and a 12 v to run an air conditioner in the front of the house I'm running 2800 watts of panels in my backyard on ground mounts. I have two sets of cables on each side of the house running out to the fence line where my panels are. I think you just sold me on burying the cable. I keep saying I'm going to get conduit and I haven't.
Sounds like a nice set up you have . when I had the 14 panels I had14 gauge wire ran and it wasn’t Direct burial I used quarter inch conduit. Then I found this 10 gauge wire was direct burial! I see no problem with using it like that. It’s also a little bit cheaper not having to buy the conduit to do 140 foot run.
@@Projectzeroto60 I've used 10 gauge on everything and it's direct burial, and I'm a hell of a procrastinator, so I'll probably just do it. My ground arrays are 7, two by four frames 56 by 58 in, so they are somewhat mobile. I think I have them mostly in their permanent spots now. I wanted them to be portable and below the fence line. If I add more, to keep from taking up more space in the backyard, I will do pergolas next to the house. When I decide to get an EV, I will build a carport on the west side of the house in the backyard and widen the gate. My whole thing has been to be non grid-tied and no permits.
@@PWoods-cd6tk sounds like you have a good plan! I buy and sell equipment so I had a mini ex on hand that made quick work of putting the wires under the ground :)
Howdy! These all in one inverter devices EXTREMELY commonly have communication cables to link each unit together, allowing them to negotiate and synchronize AC power outputs, with some units even supporting 240V/split phase and 208V/3phase power output when hooked up in "series".
Won't be free. You had to pay for all the solar batteries and inverters and wiring and wood. It's going to take a long time to pay for itself, but it's nice to be self-sustaining
I do get what you are saying but I have no opinion to get power or sell power to the grid , so the way I view it is, I’m paying to have solar power for my shop but on the super sunny days I can use the excess that would of been wasted to charge a car for free
Congratulations sir, that's definitely an impressive system you got. Enjoy it.
I appreciate it!!!
Thanks

No problem thank you for watching!!
Wow, very nice and clean looking system
Thank you!
Just built my EV gas station myself, 2kw, but not doing a whole lot of driving....still need to find a reasonable EV to buy now that I got my "gas"
You have a pretty sweet setup, thx for sharing it.
Got 10kw of batteries just to keep my gas furnace going for a few days if Grid goes down, but could add another of them Growatt and got another 1kw on panels I could add to charge a car with 240v if this 2kw system pans out and find an EV that does not cost a small house.
Im tech just "off grid" with a few loads for now, furnace fridge and some electronics, washing machine/dryer on occasion.
You should make a video of your set up!
Nice setup looking good....
Thank you!!!

Do Growatts not support split phase output? That seems like a more reasonable approach than a transformer..!

@@DingleFlopI believe you are right! If I have even number of inverter split phase is best

Its amazingly beautiful that people with money can do. Its sad that the technology has been for the ritch.
I wouldn’t consider myself rich, isn’t expensive if you do all the work yourself
@@Projectzeroto60agree with that
At 0:45, "...nine thousand kilowatts total..." Holy Cow!!! You're powering Vermont?? LOL....
***9kw my bad lol
Thank you!
Hello, did I understand you that your inverter outputs are all in parallel? If so, how are the outputs synchronized?
Howdy! These all in one inverter devices EXTREMELY commonly have communication cables to link each unit together, allowing them to negotiate and synchronize AC power outputs, with some units even supporting 240V/split phase and 208V/3phase power output when hooked up in "series".
Just what @dingleFlop said!
9,000 kW - wow that really is a lot! Maybe you could power a small town? Well done.
9kw** I misspoke. 30 kw of storage

I think your battery orientation is wrong...
What do you mean?
With those cells you really do not have to keep them flat, not like a lead acid
@@user-hg2tk3xj9y these can be in any orientation you would like
