Why Invest in Battery Storage?
A solar battery is the key to unlocking true energy independence, allowing you to use your own clean energy day and night.
Reduce Bills with Off-Peak Tariffs
Charge your battery with cheap, off-peak electricity overnight and use it during expensive peak hours, helping you reduce what you pay. Off-peak tariffs are subject to a compatible smart meter and supplier eligibility checks.
Gain Energy Security
Add a gateway to keep your essential appliances running during power cuts to ensure your battery can provide a seamless backup power source when the grid goes down.
Future-Proof Your Home
A battery system makes your home more energy-efficient, increases its value, and prepares you for the future of dynamic energy tariffs.
Maximise Solar Self-Consumption
Store the excess solar energy you generate during the day and use it at night, dramatically reducing what you need to buy back from the grid.
