Battery vs. generator — the straight version
Both keep the lights on. They're just good at different things.
Home battery
- Silent, automatic, safe indoors
- No fuel, no maintenance
- Can save money daily by shifting usage
- Higher upfront cost
- Finite runtime per charge (recharges from grid or solar)
Generator
- Cheaper upfront
- Runs as long as you have fuel — good for long multi-day outages
- Needs gas/propane on hand & maintenance
- Loud; produces carbon monoxide (outdoor use only)
- No everyday savings
Most people who want quiet, automatic backup and a lower bill go battery; a generator wins if you mainly need cheap, unlimited multi-day runtime.
