Sigenergy's SigenStor is a modular DC-coupled lithium iron phosphate (LFP) all-in-one home energy storage system, designed for residential and small commercial applications with an integrated solar inverter, scalable battery storage, and an optional bidirectional DC EV charger.
The Sigenergy SigenStor is a stackable 5-in-1 storage solution integrating a solar inverter, battery pack, battery power conversion system, energy management system, and an optional 25 kW DC EV charger with V2H and V2G capability into a single modular tower. Battery modules are available in four sizes from 5 kWh to 9 kWh, with up to 6 modules per stack. Each module has its own DC-DC optimiser, allowing old and new modules of different capacities to be mixed without the performance of one dragging down another. The system is IP66 rated for indoor or outdoor installation and features 0 ms backup switching when paired with the Sigen Gateway. The SigenStor comes with a 10-year product warranty and a 10-year performance warranty guaranteeing 70% usable capacity retention, or a minimum throughput of approximately 3.05 MWh per usable kWh, whichever comes first.
