Battery installation information

Helping you install and make the most of your battery

A battery can help you store extra energy produced by your solar system. Using this stored energy can reduce your electricity costs, and keep power on during outages.

Installing more batteries across NSW will help make the grid more reliable and stable, while also reducing our reliance on fossil fuels. This will help reduce NSW’s emissions by 70% by 2035 and achieve net zero by 2050.

The below resources can help you prepare to install a battery at your premises.
