FAQ

Backup Power questions homeowners ask first

What size power station runs a refrigerator?

Many refrigerators need a 1,000Wh to 2,000Wh class unit for useful overnight coverage, but compressor cycling and surge matter.

Can a solar generator replace a gas generator?

It can replace one for quiet essential loads, but high-wattage heating, central AC, and long outages still need careful planning.
