Overview

The SigenStor is a five-in-one system that stacks a solar (PV) inverter, battery, energy management, optional bi-directional EV DC charging and whole-home backup into one tower. The Sigen Battery uses premium 314Ah LFP cells rated for 10,000 cycles at a full 100% depth of discharge, in 6.0 kWh (5.84 kWh usable) or 10.0 kWh (8.76 kWh usable) modules, with 1 to 6 per controller for roughly 5.8 to 52.6 kWh. The Sigen Energy Controller delivers up to 98% efficiency, up to 4 MPP trackers, a 0 ms backup switchover and 200% peak output off-grid. An optional Sigen EV DC module adds 25 kW bi-directional V2X charging straight from solar.

Pros

  • Premium 314Ah cells: 10,000-cycle life and 100% depth of discharge
  • Up to 98% inverter efficiency with up to 4 MPP trackers
  • Optional 25 kW bi-directional V2X EV charging from solar
  • Modular: 1 to 6 battery modules (≈5.8–52.6 kWh), 0 ms backup switchover

Worth knowing

  • Newer brand in the UK than Tesla or SolarEdge
  • Larger configurations carry a high upfront cost
