Scenario at my home: In my home, refrigerator, washing machine etc and other heavy duty appliances(16A current) and lights and fans are connected to the same power line. It was a mistake done during house construction and we realized it much later. Because of this I can't use a backup power supply like Inverter when grid power goes off as the inverter can't supply enough power to run refrigerator or washing machine.
I am looking at options to solve this problem. I want to use an inverter to just run lights/fan when grid power goes off. Refrigerator should not get power during this time.
I thought of getting it rewired so that light/fans and refrigerator are on different power lines. But this is difficult.
So I am looking at options. Any help is appreciated.
