Backup power questions
How long will a home battery run my house?
A day or more on essentials, for a typical 13.5 kWh battery. Solar refills it.
Do I need solar for a home battery?
No. It can charge from the grid and still back you up.
Do you charge for the quote?
No. An electrician looks at the job in person and quotes it, free.
