A solar battery lets you keep more of the power you generate, use it after the sun goes down, and stay running when the grid goes down. Greater savings, greater independence, and the confidence of knowing your home is powered no matter what.

Add a home battery, with or without solar. Store cheaper power to use when prices are high and keep the lights on if the grid goes down. Easy to install and it works with any existing solar system or on its own. From $9,999 installed, with a 15 year warranty.
Solar generates during the day. Most New Zealanders use the bulk of their power in the evening. Without a battery, you sell your daytime surplus cheaply to your retailer, then buy power back from the grid in the evening. A solar battery closes that gap, letting you draw on your own solar long after the sun goes down.
Store the solar you generate during the day and use it through the evening, when household power use is at its peak. Without a battery, around 70% of your generation is sold cheaply to the grid; with one, self-consumption typically rises to 70 to 90%, depending on usage and battery size.
When the grid drops out, your battery keeps your essential circuits running automatically. Lights, fridge, internet, key power points, all still on. Storms, planned outages, and unexpected blackouts stop being a problem you have to think about.
Reduce your exposure to rising retail electricity prices, and reduce the sting of high line charges. Or, for households ready to take the next step, opt for off-grid and enjoy total energy independence.
A battery is a long-term asset, not a quick win. It adds a few years to a solar-only payback, then keeps earning across its 10 to 15 year life by turning solar you’d have exported into power you use yourself. How far ahead you come out depends on how you use power, so we size the battery to your home to make sure the long-term numbers stack up.
The newest battery in the Future Energy range, designed specifically for easy retrofit to existing solar systems. If you already have solar and want to add storage without replacing your inverter, Atmoce is built for you.
The household name in home battery storage. The Tesla Powerwall 3 stores 13.5 kWh of solar energy in a compact, all-in-one unit with an integrated inverter, sleek design, and the well-regarded Tesla app for monitoring and control. A strong choice for homeowners who want a proven, premium brand, automatic outage backup, and a system that’s familiar to electricians and inspectors across New Zealand.

Modular and scalable. SolaX batteries stack vertically so you can start with the storage you need today and add capacity later as your household changes (a new EV, a heat pump, a growing family). Strong pairing with SolaX inverters for a fully matched ecosystem, and a popular choice for homeowners who want flexibility to grow their system over time. Learn more about SolaX
Premium European engineering with an all-in-one design. Sigenergy systems combine solar inverter, battery storage and (optionally) EV charging into a single integrated unit, controlled by an AI-driven energy management platform that optimises self-consumption automatically.
