Home Battery Storage Systems
Capture 100% of your daytime solar surplus, eliminate evening peak grid tariffs, and protect your home during power cuts. We supply, install, and commission certified Tier-1 battery systems from SolaX, Fox ESS and Duracell.
Why Add a Battery to Your Home?
Without battery storage, up to 60% of your generated solar electricity is exported to the grid for pennies while you buy electricity back in the evening at full retail rates.
Use Free Solar at Night
Store excess solar during sunny midday hours. Run your ovens, heat pumps, computers and lighting after dark without paying peak grid rates.
Off-Peak Smart Charging
Charge your battery overnight at 7p/kWh on tariffs like Octopus Agile, Go or Cosy. Discharge during expensive 32p/kWh peak hours to save hundreds each winter.
Emergency EPS Backup
When storm gales trip the local national grid, your battery's Emergency Power Supply (EPS) seamlessly powers your critical circuits in milliseconds.
The 5 Leading Systems We Supply & Certify
We offer impartial, honest recommendations based on where the battery will be positioned (indoor, loft, unheated garage or outdoor), your household consumption and your budget.
SolaX Power Gen4 Triple Power
The UK's top choice for external and unheated garage installations. SolaX's Gen4 Triple Power battery system incorporates active internal heating mats that allow full charging performance even in freezing temperatures down to -30°C.
- Active Heating: Maintains optimal cell temperatures in freezing winters without power degradation
- Capacity: 5.8kWh base module expandable to 11.6kWh and 17.4kWh
- Switchover Time: Under 10ms seamless UPS backup during UK power grid cuts
- Tariff Pairing: Built-in dynamic integration with Octopus Agile and Flux export schemes
Fox ESS EP Battery + H1 / KH Hybrid Inverter
Fox ESS high-voltage EP batteries paired with an H1 or KH hybrid inverter. Charge on cheap overnight rates or from your solar panels, then use that energy in the evening when grid prices are highest.
- Modular: EP6 (5.76 kWh) or EP12 (11.52 kWh) modules, expandable later
- 90% Depth of Discharge: more of the stored energy is usable
- IP65 Rated: suitable for indoor or outdoor mounting
Duracell Energy Bank
Powered by Duracell's trusted battery technology. Designed to pair with the Duracell DuraCharger EV unit for an all-in-one ecosystem controlled via the intuitive DuraPower mobile app.
- Modular Storage: 5kWh base block stackable up to 15kWh residential storage
- EV Sync: Prioritizes car charging from clean battery reserve before touching the national grid
- UK Support: Dedicated UK engineering helpline and rapid hardware replacement guarantee
Charge at 7p, Power Your Home For Free: The Smart Tariff Revolution
You don't need tropical sunshine to make a battery pay for itself. Pairing a modern battery with dynamic tariffs like Intelligent Octopus Go, Octopus Agile, or British Gas Electric Driver lets you buy energy at night for ~7p/kWh and run your home all day at a 70%+ discount.
1. Overnight Supercharge
While you sleep, your hybrid inverter automatically fills your battery modules directly from the grid at rock-bottom off-peak prices. Even on freezing, overcast British winter days, your battery starts the morning 100% full.
2. Peak Rate Immunity
When daytime prices spike to 24p-28p/kWh, your home seamlessly runs on your 7p stored energy. Kettles, ovens, washing machines, and heat pumps run completely shielded from the expensive daytime grid.
3. Store Your Own Solar
On sunny days, surplus solar charges your battery instead of flowing straight to the grid, so you use your own free electricity in the evening.
