What Happens if The Grid Goes Down?

Because you produce your own power, when that grid goes down your system has to be turned off to protect the transformer in the journeyman working on it. This is when a home generator battery comes in handy, if the power goes out your generator will be used for critical power. Although this doesn’t include water heaters or a/c it does power the critical parts of your home. New microinverters technology can actually power your home even through some critical loads. The length of time your back up power lasts all depends on the KW in your backup system and specific needs of your home.
