Yes. Home batteries come with a manufacturer’s warranty, usually defined by a number of years and a minimum retained capacity or energy throughput. Batteries installed by Smart Energy Answers are also covered by our 10-year workmanship guarantee and our 5-year Whole-of-System Warranty, which includes onsite labour.
Manufacturer warranty terms for the batteries SEA installs, from each manufacturer’s Australian warranty, as at November 2026:
| Battery | Manufacturer warranty (summary) |
|---|---|
| Tesla Powerwall 3 | Tesla’s AU/NZ warranty: 10 years against defects. 70% of 13.5 kWh rated capacity at 10 years, with a 37.8 MWh throughput limit for uses other than solar self-consumption, time-based control and backup. If the Powerwall is offline for an extended period or not registered, Tesla may honour only four years. |
| Sigenergy SigenStor | Sigenergy’s AU/NZ warranty: 10 years for the battery. At least 70% usable energy for 10 years or a minimum throughput, whichever comes first. Must stay connected to the internet. If it’s offline for more than a year, cover reduces to 5 years. |
| ESY Sunhome | ESY’s AU warranty: at least 70% of available capacity for 10 years (120 months) from installation, subject to a throughput limit and other conditions. Must stay connected to the internet, or the warranty may be voided. |
| SolarEdge Home Battery (400V) | SolarEdge’s Australian product page states a 10-year warranty without cycle limitation. Full terms are in SolarEdge’s separate battery warranty document. |
