Powervault

At Powervault, we are on a mission to pioneer a sustainable energy future. We provide the most intelligent, economic and sustainable energy storage systems for homes and businesses. Our products store solar energy and affordable electricity from the grid, helping save you money while you help protect the environment. We design and manufacture Powervault here in the UK. Powervault stores your surplus solar power and low-cost electricity from the grid, supplying your home more cost-effectively. Powervault’s intelligent software is compatible with all Time-of-Use electricity tariffs, including Octopus Agile, so users with or without solar can benefit from lower bills. Worldwide, we must all get to ‘Net Zero’ carbon emissions by 2050, and your journey starts with Powervault. We can’t control when the sun shines or wind blows, so energy storage is the key to unlocking 100% clean energy. By choosing Powervault you are helping pioneer the sustainable energy transition from your home. Your commitment to protecting the environment comes with added benefits through the Powervault community. In addition to reducing your bills, by signing up to our GridFLEX™ platform you can earn an extra £120/year guaranteed for joining our community of batteries supporting the electricity grid nationwide. By storing solar electricity during the day and low-cost electricity overnight, Powervault shifts your energy usage to times of day when carbon emissions are lower. This reduces the climate impact of the power you use and helps alleviate the UK’s dependence on creaking old fossil fuel infrastructure. Working closely with energy suppliers, DNOs and National Grid, our GridFLEX platform optimises fleets of Powervault batteries installed across the UK to provide flexibility and in turn helping to decarbonise the network. By intelligently ‘turning up’ or ‘turning down’ home energy usage we can help balance the grid and make the most of renewable generation. Want to go even greener? Powervault has developed the UK’s first energy storage system giving a ‘Second Life’ to batteries that have been used in Renault and Nissan electric vehicles. The Powervault 3eco is a durable, low-cost, low-impact solution driving the shift to a circular economy. Monitor your energy usage and control your Powervault and spending via any device. Powervault’s portal gives you a complete picture of your energy production and usage every moment of every day, live and historic. Our intuitive app is the perfect companion on your journey to lower bills and lower carbon.

The P3 Eco product is an excellent idea. Gives former electric car batteries a second life and reduces household peak time electricity consumption all year round. In the Summer on sunny days, a 6kWh battery plus a 4kW solar PV system is enough to mean no electricity is needed from the grid at all. In the winter, it still helps out by charging on cheaper, off peak electricity and then discharging during peak hours. Realistically, the system will take several years to pay for itself in terms of reduced electricity bills, but it is nevertheless very satisfying to know that your own home is doing nothing to increase the demand for electricity at 6pm, all year round.

Have now been in touch with customer service and system fault Is being looked in to .06/06/2022. Customer service is a joke, had a system fitted ,area to be fitted was given the ok as it was ina cupboard. Worked well for 4 to 6 months then it started cutting out,emailed themaftrr 24hrs got a reply saying overheating problem and it would be reset and turned downtown help. This has happened several times now and each time it has been reset after waiting g for reply from email.everyti.e saying heat problem or generation turned down .this defeats the object of having it if the power is reduced or takes longer to build up. Still doi g this have emailed plenty of times but no dry back , have now phoned and got someone e on the phone who said an engineer would call to arrange a home visit to fix problem . Still waiting for a call back and system has gone down again nearly 3 days and over a week waiting g for engineer to call.

Committed to customer service. Having had the battery installed for some time now, I am confident about the product and the support. When something would not work, they fixed it. When I needed to change my schedules, they gave clear advice. I am happy that I purchased this product, which I would recommend to anyone with Economy 7 or a decent solar system

We had the new P3 system installed in June 2019 and have made significant savings to date. I feel quite content knowing that our evenings are being battery powered and that for a large part of the day we are being battery powered. Last year with the G200 system we bought 1.7kW of electricity whilst generating by PV panels 5 MW some of which powered the household requirement and some of which was exported. All that is required is for the "Dashboard" to have incorporated into it a state of battery charge indicator as we cannot tell when the batteries are in need of top-up by Economy 7.
