I purchased a UPS system from Bestbuy a while ago. My father who is on a fixed income is trying to reduce his electric bill. He usually keeps one lamp on at night and turns off his water heater and air-condition.
If he had my UPS and ran it at night to power lamps. Would this be a cheaper option? After usage I know it will need to charge but will the charge be the same cost as running lamps?
I figure the lamps will use more watts but to charge the UPS should be less.
