Stop Exporting Cheap.
Use Your Own Power.
A home battery lets you store the solar energy you generate and use it at night — instead of exporting it to the grid for a fraction of what it's worth to you.

Why Add a Battery?
Power Through the Night
Store excess solar energy during the day and use it after sunset. Dramatically reduce — or eliminate — evening grid imports.
Maximise Your Solar Value
Without a battery, surplus solar exports at 10c/kWh. Use it yourself instead and save at the full grid rate of 32c+/kWh. The maths is clear.
Protection from Price Rises
Lock in the value of your solar by using more of what you generate. Less grid exposure means rising Synergy prices matter less to you.
Smart Energy Management
Modern home batteries are intelligent. They learn your usage, forecast solar production, and automatically optimise charge/discharge cycles.
Battery Questions Answered
How much battery capacity do I need?
For a typical Perth family of 3–4, a 10–12kWh battery covers most evening loads. Larger homes or high evening usage may benefit from 15–20kWh. We size the battery based on your actual usage data during the site assessment.
Can I add a battery to my existing solar system?
In most cases, yes. We assess your existing inverter compatibility during the site visit. Some older inverters require replacement; others can be paired with a compatible battery system directly.
How long does a home battery last?
Most modern home batteries are rated for 6,000–10,000 charge cycles and come with 10-year warranties. At one cycle per day, that's 16–27 years of operation.
What's the payback period for a battery?
Typically 5–9 years on its own, or 3–5 years when installed alongside a new solar system. The financial case strengthens each year as electricity prices rise.
