Need help with NEC690 and UL 969 compliance

[Willdog]

Hi all,

I am building off grid solar systems that consist of:

2 - 100 watt panels
1 – 12 volt, 30 AMP battery charger- Max solar input 450watt
1 - Pure sine 2200 power inverter – 4400 peak
8- 35AH seal batteries

Can anyone tell me what will be my back feed breaker AMPS?
Maximum allowed PV breaker?
Do I need a service panel or just a disconnect switch?

Thanks for your help

As stated in your other thread the system is poorly conceived and designed and will not work.

But to answer your question assuming the panels are wired in series there is no requirement for a breaker between the panel and CC.

"Backfeed breaker" is use for grid tie, not for off grid.
PV breaker? On the AC or DC side of the CC or on the inverter?
You need a main panel of some sort for a totally off grid system, but since the source is not POCO it would not be called a service panel or disconnect.
