”How much does Powervault cost?”

The cost of a Powervault energy storage system will depend on the capacity of the system you have selected. The company offers batteries with a 4, 8, 12, 16 or 20kWh capacity. These range in price: with the lower end costing around £4,700 whilst the higher capacity models can cost up to £14,000. They also supply an Eco range which has a lower energy capacity and is considerably cheaper. 

What is Powervault?”

A powervault system sits in the middle of your home’s devices and your property’s solar panels. Energy generated by solar panels is stored in a Powervault system. This can then be distributed and accessed to power devices around the home. In addition to energy consumed from solar panels, Powervault batteries have the ability to charge themselves from the national grid during off peak hours. Both instances reduce household energy bills and help homeowners to reduce their carbon footprint.
