3 strings. The installer actually wired them wrong but after correcting that it was still low. Today I got 82.2 kWh from the system. It was clear and sunny all day. Yesterday I called the inverter manufacturer (Sol-Ark) tech support and they immediately identified that the "Solar Sell" button...

Thanks for feedback. Today I got 82.2 kWh from the system. It was clear and sunny all day. Yesterday I called the inverter manufacturer (Sol-Ark) tech support and they immediately identified that the "Solar Sell" button was off so the inverter was choking production to match the load. Wasted...

Hey great estimate! Today I got 82.2 kWh from the system. It was clear and sunny all day. Yesterday I called the inverter manufacturer (Sol-Ark) tech support and they immediately identified that the "Solar Sell" button was off so the inverter was choking production to match the load. Wasted...

Not that I know of. I am under NEM2 with PG&E

That is awesome! Something is definitely wrong with my system. : (

The 14.4 system is elevated 10' ground mount all panels facing south. Yes I suspect that is low. Thanks!

Thanks! I will check PVWatts. Both ground mount systems with all panels orientated same direction

Both systems are ground mount. Temp at both locations are about the same. All panels have same orientation.

@Tomthumb62 thanks for the reply. My other home has a 8.16 kW system and it produced 49.9 kWh yesterday. It is near Fresno so conditions are similar. Why would this system which is a lot smaller produce about the same?

Hello! We just commissioned our 14.4 kW DC system on Aug 14. It has 36 panels 400 watts each. My highest daily PV production was 50.1 kWh yesterday Aug 23. System is in Fresno CA and yesterday was clear and sunny all day. I think this is low for a system this size. Figuring about 5 hrs of good...

Right. I will add those fuses and the DC circuit on both sides of the controller. Did not know about the load to solar charge controller circuit that bypasses the batteries. Thanks!

@HRTKD okay. watt hr =2520 regardless so I should wire batteries in series. Thanks. @madsci1016 if I wire batteries in series then I won't need the regulators. Thanks to both of you. Where should I put a fuse?

No. Didn't calc it but figured there might be some loss. Not sure how much. I better look at watt-hrs.

Thanks HRTKD. Batteries in parallel gives me 430 AH instead of 215 AH. Should be able to run the load for longer. That's why I planned it that way. Transformers are only about $70 for both.

Hi I'm planning a system to power my gate opener and perimeter LED lights. Can you have a look at the attached jpg and comment? The goal is to maximize amp-hrs of the batteries. Thanks in advance!
