Why Choose SigenStor?
SigenStor offers flexible sizing to fit both small and large homes. Its modular design allows you to start small and expand as your energy needs grow. The vertical stacking saves valuable space, and the lightweight modules make installation simple and fast. With smart energy management and strong safety features, SigenStor is designed to meet the changing needs of UK homeowners.
The system includes a solar inverter, battery pack, power converter and energy control. It delivers up to 12 kW of electricity. The battery can store up to 48 kWh of energy per stack.
The Little Green Energy Company now brings this advanced system to homes in the UK. Homeowners can expand storage easily using various sizes of storage units from 5 kWh to 10 kWh battery units. The system is weatherproof and comes with up to a 15-year warranty. You can control and monitor it from an app on your phone.

What Is SigenStor and How Does It Work?
SigenStor is a complete energy system. It lets homeowners manage solar, battery storage, electric vehicle charging and power use.
Solar panels make electricity for your home during the day. Extra energy charges the batteries. The system decides how to use power based on your home’s needs.

The AI-powered control system helps save money and energy. It chooses when to store, sell or use electricity. You do not need to control it yourself, but you can monitor it through the app.
How Does It Combine Solar and Battery Storage?
SigenStor connects solar panels and batteries into one simple system. During the day, your home uses solar energy first. Any extra energy charges the batteries for use later.
The system manages energy flow efficiently, helping you store as much solar power as possible. This reduces your reliance on the grid and helps lower your energy bills. The smart design ensures minimal energy loss during the charging and discharging process.

Smart Energy Management and Simple App Control
The Energy Management System uses AI to study your home’s power use. It checks your energy use, solar forecasts and energy prices. Based on this, it stores or sells power at the best times.
The mySigen app helps you monitor and control the system. You can check power levels, schedule charging times and adjust settings from anywhere. The app also explains how your system is working in simple terms.

Modular Design, Safety and Flexible Growth
Storage Options
You can build your system to match your needs. Start small or go big over time. Each module holds from 5 kWh to 10 kWh of energy.
You can add up to six modules to one system for 60 kWh total. Multiple systems can link together for even more storage. The system can sit indoors or outdoors and is protected from bad weather.
Five Layers of Safety
The system has strong safety features:
- Heat pads stop fires from spreading.
- Two layers of insulation add extra protection.
- A built-in fire extinguisher activates at high temperatures.
- A valve releases pressure safely.
- Sensors monitor temperature all the time.
Mixing Old and New Batteries
The system lets you combine older batteries with new ones. You do not need to replace the full system to upgrade. The smart optimiser keeps all parts working well together.

Fast Installation, Warranty and Long-Term Value
Easy Installation
The system is designed for quick and simple installation. Each battery module clicks into place without extra wiring. The app automatically connects the whole system. Most full installations take less than one day.
Warranty
The system includes a 10-year warranty. This guarantees at least 70 percent battery capacity after 10 years. You can also buy a 15-year warranty within the first year for extra cover.
Flexible Options to Match Your Home
SigenStor is designed to fit a wide range of homes and energy needs. Whether you want a small system to start with or a larger setup for full energy independence, the modular design allows you to build the right system for your household. The flexible design also makes it easy to expand your storage capacity in the future as your needs grow. Installation costs are often lower compared to more complex systems, thanks to the simple plug-and-play setup.
