Standby Generator vs Home Battery: Which Backup Power Is Right for California Outages?
Between wildfire-season power shutoffs and winter storms, backup power has moved from luxury to necessity across California. The two main options, a standby generator and a home battery, solve the problem in very different ways.
Standby generators
A standby generator installation connects to natural gas or propane and starts automatically within seconds of an outage. It can run indefinitely as long as fuel is available, making it the strongest choice for long multi-day shutoffs and for homes with well pumps, medical equipment or large HVAC loads.
Pros: unlimited runtime, powers the whole home, lower cost per kilowatt of capacity.
Cons: noise, annual maintenance, fuel dependence, a concrete pad and clearance requirements.
Home batteries
A battery backup installation such as a Tesla Powerwall or Enphase system is silent, maintenance-free and pairs with solar to recharge during the day. It switches over instantly, so you will not even notice an outage begin.
Pros: silent, no fuel, works with solar, daily bill savings through time-of-use arbitrage, incentives available.
Cons: limited capacity per unit, higher upfront cost for whole-home coverage.
Which is right for you?
- Frequent multi-day outages and no solar: generator.
- Existing or planned solar and shorter outages: battery.
- Maximum resilience: both, with the battery handling short events and the generator covering extended ones.
Either way, start with the panel
Both options require a transfer switch or backup gateway and often an electrical panel upgrade. Our generator installation and battery teams start every project with a load calculation so the system is sized for your actual needs.
