Utility solar manager sent the solar inspector out to see what I had. Said the existing CB disconnect, next to meter, was OK but a second needed at the solar building and grid tied would be approved pending final inspection.. He did pull the meter and confirmed three lugs, one going directly to the disconnect. Kicking myself for not getting a picture of the open meter. Worst case is a 200a CB at the beginning of a 50' run to a 200a main.
With a 100a panel currently in the shop, I can run a 200a line to a new 225 amp panel with one breaker for the inverter. Breaker sized to accept Growatts 48 amps but I want panel and line able to carry higher, or added, inverter amps. May hit the lottery and go hybrid with batteries.
Solar AC leaves through the new panel/breaker, disconnect, and over to the tap on the meter disconnect line. Looks straight forward to me but no idea how many code rules I stepped on. And I thought panel watts, string size, inverter limits was the complicated part of solar.
Thanks for the help.
