I'm thinking that switch is the on/off for power leaving the inverter, whether the AC power is just passing through or if the inverter is actually making AC from the batteries. What happens if you turn off power to your rig, does the inverter continue to power the fridge? Do you have a manual for the inverter? What brand and model is the inverter?
