Thanks Zeke, Phil, Bill etc for the thoughtful responses.
In conclusion it appears that an outlet whether 120VAC (standard GFCI outlet) or 240VAC (14/50 for EV) can be tapped off a solar 50A branch circuit with an appropriate 20A or 50A breaker at any outlet. I can't send my schematic (showing "combiner" breaker box or sub panel at array) , but would be obvious, pictures speak 1000 words. The bottom line is I always *submit* my schematic to the AHJ in order for the homeowner to obtain an electrical permit *prior* to any wiring. As long as the AHJ stamps "Approved" on my schematic - I'm good. Have a renewable energy day, Mark Mark E.

It's legal to connect the PV to a subpanel, or a series of subpanels, as long as you follow the 120% rule all the way back through every panel along the way. -------------- next part -------------- An HTML attachment was scrubbed...
