A normal home inverter stores grid power in a battery and gives it back during a cut. It saves no electricity; it only moves it in time, and loses some in the process. Solar makes new electricity from sunlight.
| Home inverter / UPS | Rooftop solar | |
|---|---|---|
| Reduces the bill | No | Yes, by 80–95% of energy charges |
| Backup in a cut | Yes, for a few hours | Not on-grid; yes with hybrid and battery |
| Lifespan | Battery 3–5 years | Panels 25 years |
If outages are rare, an on-grid system is the better value. If you need backup, a hybrid inverter can replace your old inverter. See on-grid vs hybrid.
