Generator & Battery Backup Hookup

Connecting a generator or battery backup system to your home's electrical panel involves a transfer switch and utility-interconnection wiring that has to be done exactly right for safety — a bad hookup can backfeed the grid.

Generator and battery backup hookup across the Bay Area

Whether it's a portable generator for wildfire-season outages or a whole-home battery backup system, the interconnection to your panel is the part that has to be done by a licensed electrician — it determines whether the system actually isolates from the grid during an outage, which is a real safety requirement, not a formality. NorTech verifies an active C-10 license before dispatching a provider to this job.

Portable vs. whole-home backup systems

A portable generator interconnection is a simpler transfer switch setup for essential circuits, while a whole-home battery system often integrates with existing solar and covers the entire panel. Your electrician can advise on which fits your backup power goals and budget during the sizing consultation.

Planning around Bay Area outage patterns

Wildfire-season public safety power shutoffs tend to last longer than typical storm outages, which changes how much backup capacity actually makes sense for your household. Your electrician can factor realistic outage duration into the sizing conversation rather than planning around a worst-case single evening.
