Hi,

just want to ask if the 200A MLO load center is code compliant? does anyone knows if the pv load center is exclusively for pv breaker only? and what chapter/section does the label "solar source only" refer to NEC? Thank you!

I think the compliance of designs like this is questionable (not to mention inferior to other available options). I know Sol Ark and probably others suggest it but it always raises my eyebrows.

The label has no NEC basis.

This label was often used for PV inverter AC combiners. It is not an NEC requirement but I have seen it used often on panels that qualify for 705.12(B)(3). But 705.12(B)(3) requires a different label.
