I currently have a SMA Sunny Boy 6KW inverter for our solar system which is grid connected. I also have a 125 amp/50amp manual transfer switch to allow my 9KW propane generator to route limited power to the house main breaker panel for when power is out. I first turn off almost all breakers in the main panel except for a mini-split A/C breaker, and a few 110 breakers for the refrigerator/freezer, internet modem, and a lighting circuit. This installation works fine.
I would like to do something to allow use of a separate 110 outlet that the Sunny Boy inverter supports for daylight use of the solar energy and not have to always use the generator when the grid is down. Since this outlet only supports 2200 watts I would like to use it basically when the weather is nice but I want to keep the refrigerator/freezer running. Obviously, an extension cord from this outlet to the refrigerator would work but this involves moving the refrigerator to switch the plug which is not an easy task.
Can anyone suggest a safe way to get power to refrigerator without having to move it each time to sometimes use this capability for limited power from the inverter? Yes, I have a EE degree but I basically only do basic house wiring.
