Key data
Key data & performance metrics.
5-in-1 Integration
The SigenStor eliminates the need for separate, bulky boxes on your walls by stacking the Battery, Inverter, EV DC Charger, and Energy Management System (EMS) into a single aesthetic tower.
AI & Software Innovation
Powered by the mySigen app, which uses AI-assisted energy planning and Virtual Power Plant (VPP) scheduling to autonomously maximise savings on dynamic UK tariffs (like Octopus Agile).
Unmatched Safety Standards
Features industry-leading thermal protection, including aerogel insulated pads between cells, decompression valves, and a built-in fire extinguisher within every single battery module.
UK Field Leadership
Supported by a dedicated UK certified installer network. The system features an ultra-fast 15-minute auto-plug physical installation and 5-minute software commissioning.

A brand you can trust
Built for long-term performance.
Safety First
Uses premium Lithium Ferro Phosphate (LFP) cells protected by an advanced multi-layered safety matrix, completely eliminating thermal runaway risks.
Smart Energy Management
The AI-driven mySigen app autonomously buys cheap electricity from the grid and discharges during peak times, requiring zero daily input from the user.
Scalable Design
Highly flexible modular stacking. Start with a single battery and easily stack up to 6 modules per tower (up to 48kWh). Need more? Connect up to 10 towers in parallel.
Reliable Backup Power
When paired with the Sigenergy Gateway, the system provides a seamless 0-millisecond transition during grid outages, acting as a true UPS (Uninterruptible Power Supply) for your home.
Backup power needs additional infrastructure to be installed. Please ask us for prices.
