I think the fridge will automatically switch to AC when it is available. It only runs on DC when the AC is absent. In an SMB with an inverter, that is stupid! Take your battery DC, convert it to AC with the inverter and run the fridge - which will convert it back to DC to run the motor. It might be wiser to just unplug the fridge and only run it on DC. If you are plugged in, the losses in the battery charging system are minor, and you have a surplus of power. You really don't want or need the losses of the inverter when you are running off the batteries.
