Between PSPS shutoffs and storms, more Fremont homeowners want reliable backup power. The two main options — a standby generator and a home battery — each have strengths. Here’s how to choose.
Standby generator
A permanently installed generator kicks on automatically when the grid goes down, running on natural gas or propane.
- Pros: Runs for days, powers the whole home, no “recharge” needed
- Cons: Higher install cost, needs fuel, periodic maintenance
Home battery
A battery (often paired with solar) stores energy and switches on instantly and silently during an outage.
- Pros: Silent, no fuel, works great with solar
- Cons: Limited run time, higher upfront cost, capacity limits
Which is right for you?
- Frequent, long outages or a large home → a standby generator’s endurance wins.
- Solar already installed or want silent backup → a battery is a natural fit.
- Whole-home coverage on a budget → a generator usually delivers more power per dollar.
The install matters
Both require a licensed electrician and an automatic transfer switch so backup power connects safely and legally — never back-feed a generator into an outlet.
