Solar power system for off grid application.

Inverter:
(1) -Three year old Growatt SPF 6000T DVM Split Phase 240VAC. Max PV open voltage 150. "https://us.growatt.com/upload/file/SPF_4000-12000T_DVM-US_Datasheet_EN_202212.pdf" Internal transfer switch to utility. (fast enough that you can't tell it happened).

Solar Panels:
(10) - New JA Solar JAM72D09-380/BP 380 W mono solar panels. The inverter can only accept 150V max input. (9) panels can be wired in (3) parallel groups of (3) panels in series (will need 10ga wire or so). Leaving one extra panel. I was going to install them on my garage, but it is too shady.

In the picture of the panels mounted on my cottage garage roof, the top row is the (9) REC panels the inverter was connected to for the last 3 years (3 groups of 3) the bottom row is (9) of the JA Solar panels (just finished putting them up) all are hooked up to a new larger inverter. The JA panels are working beautifully.

The frames are a bit dirty (bad shipping and packaging). I do not have mounting rails left over (I used unistrut from Home depot. (12ga))

Batteries:
(4) 3 year old Mightymax ML4D 12VDC 200Ah AGM batteries. I replaced these with LiFEPO battery packs I built. I set the inverter to switch back to utility at 40% DOD in the summer and in the winter they were held in as back up.

Misc:
I have some misc wire, connectors, CB's and a version of PVKeeper that works to track usage (USB to laptop).
