Solar generation, battery storage and energy management designed to operate as one connected system.
Flexible system architecture that can support changing household energy requirements over time.
Software and automation help coordinate solar generation, storage and household consumption.
In Sunbridge’s eyes
Sigenergy is barely older than the systems it sells — founded in 2022 by the ex-Huawei team that built the world’s biggest inverter business, and launched straight into Australia with SigenStor in 2023. SigenStor folds solar, battery, EV charging and energy management into one stackable “5-in-1” tower, and the brand has gone from unknown to one of the country’s top-selling home batteries in barely two years.
homes wanting one integrated solar-battery-EV ecosystem with room to grow — less so for buyers who want a long, proven track record, since the brand is only a few years old.
