Why does my solar house lose power when the utility is down?

Updated: Apr 14


For safety reasons, when the utility is down so is your grid-tied inverter. This is to prevent the line workers from getting shocked as they repair the lines and restore power to all.

However, there is still a way to take advantage of the sun. By adding a battery backup inverter and a battery bank, you have basically added a UPS system to your house, with the added benefit of being recharged by the sun.

Depending upon your loads and the size of the battery bank, you cold operate in a limited capacity indefinitely. While you might not be able to run an air conditioner, you can certainly keep your food cold, a few lights on a night, recharge your cell phone, and maybe even run a well pump.
