It integrates the Solar Inverter, Battery PCS, EV Charger, Battery Pack, and Energy Management System (EMS) into one device. No messy cabling, just a clean stack.
Total energy security. In a power cut, the SigenStor switches to backup power instantly (0 milliseconds), keeping your lights and internet running without interruption.
Future-proof your home. Start with a 5kWh or 9kWh module and simply stack more units later to reach up to 48kWh capacity as your needs grow.
The safest system on the market. It features 5 layers of protection, including aerogel pads and internal temperature sensors in every single battery cell.
Powered by GPT-4, the system learns your habits and trades energy automatically—buying cheap and selling high—to slash your payback period.
Forget separate wall boxes. The SigenStor is the industry's first system to offer a DC-coupled EV charger that slots seamlessly into the battery stack, creating a single, tidy energy hub.
The SigenStor is the first energy system in the world to integrate GPT-4 AI (the same technology behind ChatGPT) directly into its operating system.
While the battery provides the muscle, the mySigen App provides the brain. It is not just a monitoring tool; it is an intelligent assistant that learns your energy habits, predicts weather patterns in North Wales, and controls your system automatically.
The AI links with dynamic tariffs like Octopus Agile. It sees price plunges (or negative pricing) coming 24 hours in advance and schedules the battery to charge from the grid when energy is cheapest.
Using hyper-local weather data for Chester and Deeside, the system predicts your solar generation. If it forecasts a cloudy day tomorrow, it pre-charges the battery overnight at a cheap rate so you don't buy expensive peak-rate power.
Need to change a setting? You don't need to dig through menus. Simply speak to the app: "Hi Sigen, reserve 50% battery for tonight," and the AI configures the system instantly.
While we install various battery brands, we specifically recommend the SigEnergy SigenStor for homeowners who fit the following profiles:
If you have (or plan to get) an electric vehicle, this is the best choice. The integrated DC charger allows for solar-only charging, bypassing the grid entirely for 100% green driving.
If you need to install the battery in a visible location (like a utility room or hallway), the SigenStor is ideal. It has no visible wiring and looks like a premium appliance rather than industrial equipment.
If you want to actively trade energy on tariffs like Octopus Agile to reduce your payback period, the built-in GPT-4 AI handles this automation better than any other system we install.
With a depth of just 260mm, the SigenStor is significantly slimmer than many competitors. It fits neatly against garage walls without intruding into parking space.
Yes. Approximately 40% of our installations in North Wales are "retrofits" to existing solar arrays. There are two ways we can install this for you:
Unsure which is right for you? Our engineering team can review your current setup via photos.
Installing high-tech storage requires a certified energy partner. HSB Renewables covers North Wales and the North West.
We are fully accredited, ensuring your installation qualifies for the Smart Export Guarantee (SEG). We handle all the paperwork for you.
We manage G98 (standard) and G99 applications with the grid operator. For larger projects, see our Commercial Solar page.
Our in-house roofing and electrical teams are based in Deeside. If you have an issue, you get a local engineer, not a call centre.

Yes. The mySigen app features a dedicated AI mode that fully integrates with Octopus Energy dynamic tariffs. It automatically charges your battery when prices are low (or negative) and discharges during expensive peak hours, maximizing your savings without you lifting a finger.
The SigenStor comes with a market-leading 10-Year Performance Warranty on the battery modules and a 5-Year Warranty on the inverter/controller. HSB Renewables registers this warranty on your behalf upon commissioning.
Yes, the SigenStor is rated IP66, meaning it is fully waterproof and dustproof. While it can withstand UK weather, we often recommend a sheltered location (like a carport or garage wall) to ensure optimal battery temperature during deep winter.
No. The SigenStor (up to 6kW) uses natural convection cooling, meaning it is fanless and operates at under 29 dB—roughly the sound of a whisper. It is perfectly suitable for installation in utility rooms or hallways.
In most cases, battery storage is considered Permitted Development in the UK. However, if you live in a Listed Building or a strict Conservation Area in Chester, we will check with the local authority during your site survey.
Because of its modular "stack" design, the SigenStor is easier to disconnect and move than traditional wall-mounted systems. However, a battery system adds significant value to a property’s EPC rating, so many homeowners choose to leave it and factor the value into their sale price.
