Why Choose Powervault 3 To Store Electricity In Your Home?


Powervault 3 is an intelligent battery system for the modern smart home, designed to maximise energy efficiency and value for the customer. Powervault 3 reduces customers’ energy bills by storing free solar energy or cheap, off-peak electricity from the grid. Customers can also receive an income from Powervault by allowing Powervault’s proprietary GridFLEX™ platform to occasionally control their Powervault 3 battery and support the grid when it is under stress. By connecting Powervault 3 directly to their solar system, customers can also prevent the need to replace their solar inverter when it fails.

Economic Benefits

Powervault 3 can reduce customers’ electricity bills by up to 20% by storing solar energy during the day and discharging it in the evening. Powervault 3 can also charge from the grid, which means it can store cheap, off-peak electricity. Customers on ‘smart’ time-of-use tariffs can save an additional 15% on their energy bills by storing low-cost electricity and discharging it at peak time. Powervault 3 is compatible with Economy 7 tariffs and Green Energy UK’s TIDE tariff. Powervault 3 is forward-compatible with other ‘smart’ tariffs, which are forecast to become widespread once smart meters are installed.

Environmental Benefits

Powervault 3 enables customers to use less of the energy generated by centralised power stations and more of their own, locally-generated, clean energy. Powervault works with the National Physical Laboratory to better understand the impact Powervault 3 and Powervault 3eco has on greenhouse gas emissions. The National Physical Laboratory has calculated that Powervault 3 and Powervault 3eco will, depending on the capacity of the system, reduce CO2 emissions by >300kg/p.a. in the average U.K. home.

Additional Benefits-

Smart Tariff Charging

Powervault 3 is compatible with ‘smart’ time-of-use tariffs, which vary in cost throughout the day. Using Powervault’s proprietary smart tariff controller on the Customer Portal, customers can select the charging schedule of their Powervault 3 system to ensure they benefit from low-cost energy from the grid. This provides additional benefit to customers, beyond the benefit of storing excess solar generation during the day.

Customer Portal

The Powervault customer portal provides customers with a platform from which to monitor their energy use and optimise their Powervault 3 charging schedules. It provides customers with accurate information about the present and historical performance of their Powervault 3 system. Customers can also use the smart tariff controller on the portal to optimise the charging of their Powervault 3 systems against ‘smart’ time-of-day tariffs.

Energy Independence

Powervault 3 is designed to enable customers to become more energy independent and reduce their reliance on electricity supplied via the grid. Powervault 3 allows customers to maximise the use of their clean, green solar energy and either minimise or eradicate their export to, and import from, the grid. Powervault 3 also helps protect customers against rising electricity tariffs, which are currently increasing at a rate of >6% per year.

Ease Of Installation

Powervault 3 is very simple to install and is compatible with all solar systems. Powervault 3 is an ‘all-in-one’ system, which means it contains batteries, an inverter/charger, a Battery Management System, an Energy Management System and various control boards. Customers are not required to buy additional hardware to install Powervault 3.

Compatible With All Solar PV Systems

Powervault 3 is an AC-system and is therefore universally compatible with all solar PV systems. No additional parts or adjustments to your existing solar PV system are required to accommodate Powervault 3 in your home.
