Why Powervault?

Powervault gives you more control over your energy consumption, allowing you to save more on your electricity bills. It maximises the benefits of your solar PV system by storing excess free solar energy generated during the day. It can also store cheap, off peak electricity from the grid, e.g. Economy 7, and discharge it when needed. This means you benefit from using cheaper, greener energy whenever you need it. It’s designed to enable homeowners to become more energy independent, reducing your reliance on the National Grid and maximising use of clean, renewable solar energy. Powervault is universally compatible with all solar PV systems. This means the solution is very simple to install and can be fitted to your home by a qualified electrician, with no adjustments to your existing solar PV system.
