Any Questions?
Most Frequently Asked.

Thinking about upgrading your current system with battery storage? Here are the most common questions we hear from Adelaide homeowners—covering compatibility, benefits and what to expect.

The amount of the Federal battery subsidy depends on the usable capacity of the battery. As a rough guide the subsidy is currently around 30% of the total price. For example, for a 13kWh battery you could expect to receive around $3,925 subsidy off the installed system price.

The subsidy is supposed to be available until 2030 however the amount of subsidy reduces on the 1st January each year (similar to the solar rebate). There is also another decreased scheduled for the 1st May this year (2026).

There are many options to upgrade or replace your existing solar system with a new Hybrid inverter or keep your existing solar system and install an AC coupled battery.

Each household uses energy differently however, if you have lots of surplus solar energy during the day it makes great financial sense to install a battery to capture this energy. For example, the battery kicks in later in the day when the sun goes down and the cost of buying energy from the grid is at the highest. In some cases the payback for a solar and battery storage system can be around 4 years and up to 25% simple ROI.

Each battery is different however most quality batteries have a 10 year performance warranty and whilst the usable capacity reduces over time you could expect to get up to 15 years life from a quality battery storage system.

Now’s the Time to Upgrade

Take Advantage of the new Federal Battery Subsidy

Already have solar? Getting paid a ridiculously low feed in tariff? Adding a battery lets you store excess power during the day and use it when the sun goes down. And, thanks to a new federal battery subsidy from as little as $5,500. It’s a smart upgrade that helps reduce reliance on the grid, manage rising energy costs and improve energy security—especially during blackouts.
Our team can walk you through what’s available, how to qualify and help tailor a solution that makes the most of these rebates—without the hassle.
