Our verdict
Is a Sigenergy battery right for you?
Our top-rated battery brand. SigenStor is the installers' favourite and Australia's most-installed home battery, with top specs and an easy path to expand. The 2025 controller recall was handled with replacements, but it's a young company.
Rated 8.7/10, #1 of 9 brands we rate for batteries.
A good fit if
- You want a modular battery you can grow
- You want backup and an EV charger option in one system
Maybe look elsewhere if
- You live within 500 m of the coast (check the warranty exclusion)
