SOLAR BATTERY
Sigenergy
A modular all-in-one battery, hybrid inverter and EV charger from Australia's fastest-growing home storage brand.
About Sigenergy
Sigenergy is an energy technology company founded in 2022, with local R&D based in Melbourne. Its flagship SigenStor system combines a hybrid inverter ("energy controller"), stackable LFP battery modules and an optional built-in DC EV charger into a single, modular tower. Despite being a newer entrant, Sigenergy has quickly become one of the most searched and highest-ranked battery brands in Australia by installed capacity.
Why SunPeople installs Sigenergy
We install Sigenergy for its clever modular design that lets homeowners start small and add capacity later without extra wiring, its optional built-in EV charging, and its strong feature set for the price. Its rapid rise in the Australian market also reflects genuinely well-engineered, installer-friendly hardware.
