I have a 1 Victron MultiPlus 48/5000/70 inverter charger 230 volt (not a MultiPlus 2) passing through a Victron Autotransformer and connected to a main electric panel at 110vt on each side and neutral to the neutral bar in the main panel. We now have a new diesel generator 240 volt floating neutral. I would like to power the main electrical panel through a Blue Seas AC Rotary switch 2 sources to 1 (Main electric panel), 2 position and off 65amp 240volt. The main panel is grounded to earth via large copper Rod. Generator to feed 2 hots and neutral to the panel via switch. Question #1. to keep both sources from having any issue with back feeding through the neutral Gen system and solar system could I switch neutrals in the Rotary switch for both systems and connect neutral to the grounding bar in the main panel? Since we use either the generator which is 12.5kw for big load usage including charging solar batteries through the main panel when required or we go through the solar system via the AC rotary switch and to the panel which is maxed at 5000kw. Never at the same time. Question #2 what would be the best solution for connecting these power sources? We are located on a remote Western Caribbean Island with no grid power so we are the power company.
The original installer has grounded the Solar Autotransformer, Inverter/ Charger and PV breaker panel together at a bar and then to a seperate ground rod which is approx 11' from the main Panel Grounding rod. Suggestions and Advice is greatly appreciated.
