Hi all new to this were installing a growatt spf 3000 for a 120 volt single leg to tie in and want run everything with only one ac unit we have 24 volts and 560ah and 2500 watts of panels so here's the deal would we need a 2nd transfer switch to tie in or ? The Rv currently has a 3 position transfer switch gen/shore/inverter and uses the diesel generator as priority, I've removed the stock inverter and could tie in there but.... it only runs the microwave frig and outlets inside I want to be able to run 1 of the ac units and could tie to that breaker but not sure if it would conflict? Thanks for everyone's time!
