Solar Battery Storage
Add a battery and let your solar do more. We install battery storage in Dunedin, Christchurch, Nelson, Queenstown, Timaru and Wānaka.
Smarter Solar With Battery Storage
For off‑grid to work well, the system has to be built around you – your site, your lifestyle, and your seasons.
We use a refined design process to capture the detail we need up front, so your system is properly sized and ready to perform long‑term, not just on day one.
Why Add A Battery To Your Solar System?
Save More
Buy power when it’s cheap, lean on your own solar when it’s not, and sell off what you don’t need.
With smart control, a battery helps trim your bills and lift the return you get from your solar system.
Keep The Lights On
When the grid fails, a good battery system doesn’t.
Your battery can keep key circuits running through outages, blackouts and storms – so you stay warm, lit and cooking without digging out candles.
Use Your Own Power
Run more of your home on the energy you’ve already generated.
A battery gives you greater independence from the grid, more resilience when things go wrong, and more say in how and when you use electricity – day and night.
