ARK AC-Coupled Home Battery for the UK Solar Retrofit Market
A Smart Battery Upgrade for Existing UK Solar Homes
Many UK households already have rooftop solar PV, but much of the solar generation happens during the day when electricity demand at home may be low. Without battery storage, surplus solar energy is often exported to the grid before the homeowner can use it.
ARK is designed to solve this problem.
As an AC-coupled home battery, ARK can be added to homes with existing solar systems, helping users store more of their own solar energy and use it later when household demand is higher. It is a practical retrofit solution for solar installers, distributors and private label brands targeting the UK residential energy storage market.
Why ARK Fits the UK Market
1. Existing Solar Retrofit
ARK is suitable for homeowners who already have rooftop solar PV and want to add battery storage without replacing the whole solar system.
2. Self-Consumption First
The system helps store surplus daytime solar generation for later household use, reducing reliance on grid electricity during evening and higher-demand periods.
3. Smart Tariff Ready
ARK is designed for modern energy users who want to combine solar storage with time-of-use tariff strategies, storing energy when it makes sense and using it later when electricity is more expensive.
4. SEG-Aware Energy Strategy
For UK solar homes, export income may be available under supplier conditions. ARK helps homeowners focus on using more of their own energy first, while export settings and tariff eligibility should be checked with the installer, DNO and energy supplier.
5. Flexible Battery Expansion
Start with 2.6kWh and expand step by step up to 15.6kWh, making it easier for distributors and installers to offer different system sizes for different household needs.
