Htab, open the compartment that allows you to access the water heater bypass valves for winterization. It's just ahead of the water heater and requires the brass key to open. Remove the white access cap or the black plastic panel and you will see the inverter, and switch box. If it's just like mine, it's a ProWatt 1000 with two 110vac output outlets. The refrigerator populates one of them.
