Inverter will not turn on

[SMurray]

Our inverter will not turn on in our 2018 Montana 3562. 38.5 ft. Batteries are all good. Have 4 in series. Refrigerator will not run when on the road. What am I missing? Push the ON button, nothing.

Trust that it is not because of y ou not holding the on button long enough to be seen by the inverter. Have you checked the 12vdc power into the inverter. You should have a high amperage breaker and maybe a switch in the front compartment in line from the positive terminal of the battery.

On our unit there is a 12v trigger input on the inverter, that input comes from the coach 12v not from the inverter 12v connected to the batteries. Our 12v power to the coach has to be switched on in order for the inverter to run in inverter mode (it will pass thru shore power with the coach 12v switch off).
