The ProWatt inverter you describe has to be switched on with a power switch located on the inverter. There is also a remote switch available for about $30. Switching the 12-volts into the inverter will not turn it on.
All you need to do is turn on the inverter, and turn off the converter breaker.
I doubt a DPDT switch that handles high current DC on one side and 120v AC on the other side exists, or if it does would be pricey. It also wouldn't accomplish what you envision.
So it's not a battery charger but instead a converter? Is the battery charger located someplace else?
But yea shutting off the converter is the goal.
I have revised a diagram. I think a relay would solve the problem as the ON/On switch is not feasible. I just don't want to have to remember to flip the breaker back on after turning off the inverter.
