The home was built in 1979 and the meter panel and service panel are side by side. There is no markings anywhere I can find anywhere in or on the panel. To me this seems to be not per code unless they are of the belief that my 100 amp service panel has a 125 amp buss bar. OK so far but then tied into the 100amp service panel via a 30 amp 240v new breaker. Then they would go to a 125amp combiner panel with one 20 amp breaker and another 15amp bridged to combine the outputs then connected to a 60amp lock able shut off switch.
Well the plans call for the system to be wired with 17 panels in one string and the 6 additional in a separate string. (only allowed a 20 amp solar input breaker in a 100amp panel).
100 AMP PANEL UPGRADE
I only have a 100 amp service panel and I was original told i would need a electrical panel upgrade to go bigger than about 4k in solar do to the 120% app restriction. nothing out of line there so far but here is the kicker. The basic system is 5.75kw using 23 250watt panels and enphase 215 micrconverters. I am looking over some electrical plans for my proposed solar install.
