About Sigenergy
What is the Sigenergy SigenStor?
Sigenergy is one of the fastest-growing energy storage companies in the world — ranked the #1 battery manufacturer in Australia by blended capacity in 2025, and now expanding rapidly across the UK.
The Sigenergy SigenStor is described as the world's first highly integrated 5-in-1 home energy storage system. Rather than purchasing a separate solar inverter, battery, and EV charger from different manufacturers, the SigenStor bundles everything into a single, intelligent unit.
Founded in 2022, Sigenergy has grown at extraordinary pace. Their R&D team has developed a system that uses AI to optimise energy usage, LFP battery chemistry for safety and longevity, and a modular design that lets homeowners scale from 6kWh to 54kWh over time without replacing any core components.
- Works with any brand of solar panels — including Aiko, Jinko, JA Solar, and Trina
- AI-powered energy management for maximum self-consumption
- 10-year product warranty, 10,000-cycle battery lifespan
- Expand storage capacity as your needs grow — no system replacement needed
- Integrated EV DC charging — faster and more efficient than standard AC chargers
- Full home backup via the optional Sigenergy Gateway
- IP66-rated for outdoor installation — built for UK weather

AI Energy Management
Your Home's Energy — Managed by AI
The Sigenergy SigenStor doesn't just store energy — it thinks. The built-in Energy Management System (EMS) uses AI to continuously optimise how your home uses solar, battery, and grid energy.
- Smart tariff management: Automatically charges from the grid during cheap overnight rates (e.g. Octopus Intelligent Go) and discharges during peak hours
- Solar self-consumption maximisation: AI ensures you use every kWh your panels generate before exporting to the grid
- Predictive charging: Uses weather forecasts and your usage patterns to pre-charge optimally
- mySigen app: Real-time monitoring of solar generation, battery state, home consumption, and EV charging from your phone
- Remote firmware updates: Your system improves over time automatically
- V2G ready: Future-proof for vehicle-to-grid technology with compatible electric vehicles
