InstaGen Battery Storage

Store your solar energy and use it when you need it most, cutting your reliance on the grid and lowering your energy bills*. Installs as a standalone system or alongside solar.

Take control of your energy with InstaGen battery storage. Use it on its own to store cheaper off-peak electricity, or pair it with solar to store the power you generate – either way, you’ll have cheaper energy ready to use whenever you need it, day or night.

Benefits of Battery Storage

Cheaper energy

Charge your battery on cheaper night-rate tariffs, then use that stored energy when daytime prices rise.
Maximise Solar

Store excess solar power instead of exporting it, so you can use clean, free electricity after dark.
Energy Independance

Enjoy greater energy independence and protection from price spikes.
EV Charging

Charge your electric vehicle using cheaper stored energy for even bigger savings.
