I have a project that will have 8 inverters 240V. There will be 90kW of modules installed. The site has a large generator and we need to interconnect between the meter and the transfer switch. I can get two cables from each line to the transfer switch. So I need to either combine all 8 inverters or make two groups. The total of the 8 is a max 375A. Does anyone know of a source for a combiner with disconnect and OCPD? Could I just backfeed a breaker panel?
