Sigenergy SigenStor review
By My Energy Mate Editorial · Last updated
8.8/10
Sigenergy's SigenStor is a modular, stackable battery-inverter system (8 to 48 kWh) that has become Australia's best-selling battery in 2026. Installed prices start around A$9,000 for 8 kWh. It wins on flexibility, an excellent app and integrated EV-charger options, though the brand is young and its long-term support record is unproven.
Cons
- Company founded in 2022, warranty longevity unproven
- Rapid growth has strained installer support at times

Additional things to note about Sigenergy SigenStor?
Sigenergy's key disadvantage is track record: the company is barely four years old, so its ten-year warranty has never been tested near its end. Support capacity has also lagged its explosive sales growth in Australia. Buyers who prioritise a decades-long corporate history may prefer Tesla or BYD despite higher prices.
