Sigenergy SigenStor Installation
High-capacity modular battery with built-in EV charger option.
Sigenergy SigenStor is the modular battery system we recommend when capacity needs head-room — larger homes (>10kWp solar), smallholdings, or small commercial sites where you want one integrated stack.
The killer feature is the optional built-in EV charger module — a SigenStor unit can charge your EV directly from solar without a separate wall charger. Plus three-phase compatibility, EPS backup, and the option to scale up later by adding modules.
Pricing varies widely by configuration — £8,000 for a base 5kWh unit, up to £35,000 for a fully-loaded 48kWh + EV charger setup. 15-year limited warranty is best-in-class.
