FAQs

How does home battery storage work?

A home battery stores electricity for use later. This can include available solar generation or electricity taken from the grid during selected lower-cost periods.

Do I need solar panels to install a home battery?

No. A battery can be installed with new solar panels, added to some existing solar installations or configured to charge from the grid without solar.

What size home battery do I need?

The appropriate capacity depends on your electricity consumption, solar generation, tariff, expected charging opportunities and what you want the system to achieve. Your installer will conduct a survey to determine the best system for your property and power usage.

Can a home battery provide power during a power cut?

Backup power is available where the system includes compatible backup equipment and an appropriate electrical configuration. The supported loads and available backup time depend on the inverter, battery capacity, charge level and household demand.
