Sigenergy Battery Storage UK:
Are you looking for a way to reduce your energy bills and gain independence from the volatile UK energy market?
Sigenergy offers a revolutionary solution. With a state-of-the-art Sigenergy battery system, you can store solar energy, power your home during peak hours, and enjoy uninterrupted power during outages.
This page explains the benefits of Sigenergy batteries, the innovative SigenStor all-in-one system, and how Infinity Energy Services can provide a seamless installation for your home.
What is the Sigenergy SigenStor?
The Sigenergy SigenStor is a 5-in-1, highly integrated home energy storage system.
Unlike traditional setups that require separate components, the SigenStor combines a solar inverter, optional EV DC Charger, battery converter, and energy management system into one sleek, modular unit.
This “all-in-one” design simplifies installation, saves space, and maximises efficiency, making it a leading choice for UK homeowners.
Its modular design means you can start with the capacity you need now and expand later, from 5.2 kWh all the way up to 52.56 kWh.
Key Benefits of Installing a Sigenergy Battery
Installing a Sigenergy battery storage system offers significant advantages for any homeowner with or without solar panels.
- Slash Your Energy Bills: Store excess solar energy generated during the day or charge your battery with cheaper, off-peak grid electricity. Use this stored power during expensive peak hours to dramatically lower your monthly bills.
- Energy Independence: Reduce your reliance on the national grid. A Sigenergy battery protects you from energy price hikes and gives you control over your home’s power.
- Seamless Backup Power: The optional Sigenergy Gateway provides intelligent, automatic backup power. When a power cut is detected, your system switches over in milliseconds, keeping your entire home powered, or just essential circuits, depending on your requirements.
- Future-Proof Your Home: The SigenStor system is designed for the future, with an integrated EV charger module that can be added at any time. Power your electric vehicle with clean, self-generated solar energy.
Understanding the Sigenergy Price and System Costs
One of the most common questions we receive is about the Sigenergy battery price.
The final cost depends on several factors, including the number of battery modules you choose and the complexity of the installation. A popular configuration like the Sigenergy 8 kWh battery (usable capacity is 7.8 kWh) provides a great balance of capacity and value for the average family home.
The total cost includes:
- Hardware: The SigenStor unit, up to six battery modules, and the optional Sigenergy Gateway for backup, if selected.
- Installation: Professional installation by one of our certified Sigenergy installers, including all wiring, commissioning, and setup.

Frequently Asked Questions about Sigenergy
Here are the answers to some of the most common questions we receive about SigenStor from UK homeowners.
The ideal size depends on your daily energy consumption, the size of your solar panel system (if you have one), and whether you plan to charge an electric vehicle.
A popular choice is the Sigenergy 8 kWh battery (usable capacity = 7.8 kWh), which is sufficient for many average-sized family homes.
During our free survey, we will analyse your energy usage to recommend the perfect capacity for your specific needs, keeping in mind the modular design allows for future expansion.
The current range of SigenStor batteries includes: 5 kWh (usable 5.2 kWh), 6 kWh (usable 5.84 kWh), 8 kWh (usable 7.8 kWh) and 10 kWh (usable 8.76 kWh).
Battery storage is normally installed for customers who already have, or are planning to get, a solar panel system.
Why? Because in many cases you don’t use all the solar electricity you generate. That precious, excess electricity can be stored in a battery and then discharged to the home when you need it later in the day or at night.
However, you can also install a Sigenergy system without solar panels. This would allow you to (i) charge your battery with cheap, off-peak electricity and discharge it when rates are high, and (ii) have emergency power in a power cut, assuming you opt for the Gateway.
A standard installation by a certified Sigenergy installer like Infinity Energy Services is very efficient.
Most residential installations are completed within one to two days.
We handle everything with minimal disruption to your home and ensure the system is fully commissioned and operational before we leave.
Sigenergy provides a robust, long-term warranty for peace of mind. The battery modules and main components of the SigenStor system are typically covered by a 10-year product warranty.
We will provide all the specific warranty details and documentation with your final quotation.
As of 2025, the primary financial incentive available in the UK is a 0% VAT rate on the supply and installation of Energy Saving Materials, which includes home battery storage.
This makes the initial Sigenergy price more affordable. While direct grants are rare, this VAT exemption provides a significant saving on the total cost.
Yes, the SigenStor is designed to be highly compatible. It can be installed as part of a brand-new solar PV and battery system (DC-coupled) or retrofitted to an existing solar panel installation (AC-coupled).
Our technical team will assess your current setup to ensure seamless integration.
When the Sigenergy Gateway detects a grid failure, it automatically and almost instantly (within milliseconds) disconnects from the grid and switches to backup mode.
It will then draw power from your battery to supply either (i) your home’s essential circuits, such as your lights, fridge, and internet router, or (ii) your whole home, depending on your requirements and how the system is wired up.
You likely won’t even notice the switchover happened.
The key difference is its 5-in-1 integrated design.
Where other solutions require a separate battery, a solar inverter, an EV charger, and a battery converter, the SigenStor can combine all these into one elegant and compact unit.
This simplifies installation, reduces clutter, and improves overall system efficiency.
Yes. Sigenergy offers a sophisticated and user-friendly mobile app called ‘mySigen’.
From your smartphone, you can monitor your energy production, consumption, battery charge level, and financial savings in real-time.
It gives you complete visibility and control over your home’s energy.
Savings vary depending on your electricity tariff, how much energy you use, and the size of your system.
However, by maximising the use of your own solar energy or cheap off-peak electricity, many customers see a reduction of 50-80% or more in their electricity bills.
