I can Use 3 per inverter. Or more if i get separate Bus bars. You can set the inverters to have independent Battery banks.

Perfect, thank you, this is what I've been needing to know. I was thinking on replacing 3 6500EX's with 1-2 18kPV's & 3-4 PowerPro's instead of 12 EG4 Lifepower4's. (Already have 4 & been using for 4 months. )

One question I have regarding the 18kPV & EG4 Lifepower4's is together they have a 10 year warranty. With the 6500EX it only has 5 years. If I switch to the 18kPV, will this extend my battery warranty to 10 years?
 
Any expectation of your local jurisdiction giving you a hard time about the batteries being over 20kWh and less than 3 feet apart?

I’m just learning about this seemingly nonsense requirement but wondering how everyone is handling it in the real world. I guess this is referred to as UL 9540.

Got the AC tied in today. Next will be the PV and I’m done.

Looks great, awesome setup. What is in the panel directly left of the inverters? Assume the throw left of the panel I’m questioning is a transfer switch. Looks like a combiner for the AC outs or AC in for both inverters.

Edited
I'm guessing from left to right its:
Sub Panel | Meter | Transfer Switch | MDP / AC In disconnects | Inverters

Looks great. But, you need to correct the N/G bonding.
What used to be your main panel (far left), is now a sub panel.
Neutral needs to be isolated there.
And the new main panel (to the left of the inverters), needs to have the N/G bond.
Other than that, the wiring looks neat tidy.

Edit: also the driven ground (ground rod) , water ground (if applicable), and UFFER ground (if applicable), also need to move to the new main panel.

The panel is to combine the grid. The meter actually goes there first. It’s a trailer house panel so it has a 200amp pass through. The inverters are powered from there each inverter is on a 100amp breaker. It goes to the transfer switch after that. Both loads from the inverters are on the bottom of the transfer switch.

I see what you are talking about and you are right. This was at the end of the day and I will get it changed.

Not in Texas. ?
 
Well guys I finally got my ground mount in and panels mounted. Getting this done has got me so excited.

I still have to wire it all in dig a trench, lay the pipe, and pull the wires back to the inverters.

Of course ground the array as well
