Example of what I did. I wanted to power every 110v socket through the inverter. I added a second transfer switch making the inverter dominant, that way power from the first transfer switch would be on all the time until inverter was turned on then twenty seconds later the transfer switch would allow the power from the inverter.
I have two circuits coming off the battery. One is a 100amp BMS. The camper's 12v power and charging is done through this. Also has temp cut off so if to cold it will stop the charging from damaging the batteries. Second is a 250amp using 4/0 wire going to a 3000watt inverter with a low volage battery disconnect.
I set the refrig to propane and unplug the converter. Charging is done mostly there solar.
