Why Battery Storage

Get more from every ray of sunshine

Without a battery, around 30–50% of the solar energy your panels generate gets exported to the grid for minimal return. A battery captures that energy for you to use when the sun goes down.

Power Your Evenings

Most NZ households use the most electricity between 5pm and 10pm — exactly when the sun is down. A battery stores your daytime solar for peak evening use, slashing your grid dependency.

Blackout Protection

When the grid goes down, your battery keeps the lights on. Essential circuits — fridge, internet, lighting — stay powered while your neighbours are in the dark.

Beat Peak Pricing

Electricity retailers charge more during peak hours. With a battery, you avoid buying expensive grid power during peaks — using your stored solar instead.

Maximise Self-Consumption

Without a battery, you self-consume about 30–40% of your solar. With a battery, that jumps to 80–90%. More of your own power, less from the grid.

How It Works

Solar + battery: the complete energy cycle

Your solar panels generate electricity during the day. The battery intelligently manages the flow — powering your home first, charging the battery with excess, and only exporting to the grid when everything else is full.
