Every product in the Powervault range is designed to reduce energy bills by storing unused renewable energy and low-cost electricity from the grid — making cheaper, greener energy available when you need it.
Powervault's smart technology unlocks the ability to store and use off-peak energy when the sun doesn't shine and still maximises solar usage when it's available.
Easily increase the capacity of your Powervault without needing to replace the whole system. Powervault's unique modular design makes installation and upgrades simple.
With less reliance on the grid, you're insulated from energy price hikes, and emergency power sockets give you peace of mind even if there's a power cut.
Take a peek at the technology behind Powervault's market-leading performance:
Powervault's battery system is smart enough to proactively prioritise its storage and make the right decision, every day. Using smartSTOR™ technology, Powervault blends off-peak grid charging and solar storage in perfect harmony, with no hassle and no compromise.
Absolutely. Variation in energy usage is common for businesses and households, and it’s not a problem for Powervault. The smartSTOR™ system takes your unique energy usage into account and adjusts accordingly.
All Powervault products are designed to make sure you get the most out of your system without needing to adjust anything manually.
It’s easy to see how much energy you’ve stored, using our market-leading management software, allows you to stay informed and in control of your energy use on any device.
Plus, all Powervault storage systems come with an easy-to-read LED display that provides real-time data on energy storage levels, input and output.
No, you don't need solar to use a Powervault battery. While it's designed to optimise the benefits of solar, you have a couple of other options:
• Pair it with other renewable sources like wind energy.
• Use a Time-of-Use (ToU) tariff, although this option is riskier and provides a slower payback.
We always advise that the perfect combination is a Powervault with renewable generation and a time of use tariff.
Choosing the right size for your Powervault system might seem a bit complex, but our range has something for every home or business.
To find out exactly what size you need, you can get in touch with our friendly team or use our contact form. With just a few details of your energy usage, we can recommend the best product for your circumstances.
You can rest assured that with Powervault’s modular design, you can choose a unit that makes it easy to upgrade in the future, should your needs change.
Powervault units are designed for indoor use only. They need a well-ventilated space that’s not a loft space.
Most Powervault users install their units in a garage or utility area where there’s plenty of space and air circulation. When you buy a Powervault, your installer will advise you on the best place to install your system.
