Hello,
I have a basic question about the wiring from the roof when using SunPower AC modules.
Essentially each group of 12 modules is a 20 amp circuit with two hots and ground.
So let's say I have 100 modules, that's five circuits. Code wise how can I deal with the ground wire? can I run a single #8 to the roof and connect the five grounds from each circuit to this one #8? Or do I have to run a separate ground for each circuit back to the combiner panel?
Thanks for the advice.
