A battery makes the most sense when the grid pays you little for the power you send back, or when power cuts are common where you live.
| Your situation | Battery worth it? |
|---|---|
| Low export rate | Yes, usually |
| Frequent power cuts | Yes, for backup |
| Time-of-use tariff | Yes, charge cheap, use at peak |
| Full net metering | Less so, but backup still helps |
| No solar yet | Add solar first |
Sofia can model your bills with and without a battery before you decide.
