I'm hoping to find options to upgrade or replace my existing system to minimize my utility, SDGE, expenses. A pass-through inverter with battery capacity is a very attractive option, if I can find one.
My SDGE service is 125A and has been derated to accommodate the 20A inverter breaker.
Increasing my service will require some trenching and a larger conduit. Read $ here.
SDGE indicates that I can increase the total panel wattage by 1000 without moving to NEM3, but of course that mandates additional inverter capacity.
An ABB 3.6 or 3.8 these can be purchased on EBay used and it looks like the dedicate breaker is still 20A, this would accommodate the extending of the strings for the additional panels and the increased wattage. the inverter would be a straight swap. (Understanding few things are as easy as a straight swap)
