I have a very nice, expensive, pure sine wave Magnum 2000w inverter/charger. Also have the remote control panel to go with it. It has the automatic transfer to inverter but I don't use it.
Much prefer to do it the manual way so that I do not find myself killing the battery bank in no time as the inverter tries to heat the water or run the fridge. It is a simple matter to turn the water heater, the fridge, the built in heaters & microwave circuit breakers off & turn the inverter on when wanted for the outlet circuits.
