Home Battery Installation Sydney

Store your solar and use it after dark. Sydney Power Group installs home batteries as CEC-accredited installers, which keeps your system eligible for battery incentives — eligibility depends on your system and the current NSW and federal schemes, so we'll explain what applies to you without overpromising.

We size the battery to your consumption, solar generation and backup goals, and install it safely in line with AS/NZS 5139 (the standard for battery energy storage installations).

Sizing and backup done right

The right battery size depends on how much solar you generate, when you use power and whether you want blackout backup. A battery that's too small won't cover your evening load; too large and you're paying for capacity you rarely use. We model this around your actual usage.

If backup matters, we can configure a backup circuit so selected loads — lights, fridge, comms — keep running during a grid outage, and pair it with your existing or new solar installation.

Hybrid vs AC-coupled

Where you have compatible solar, a hybrid inverter can manage panels and battery together efficiently. For existing systems, an AC-coupled battery adds storage without replacing your current inverter. We'll recommend the approach that suits your setup and budget.

Already have solar and just want storage added? See battery upgrades.

Safe siting and compliance

Battery location matters for safety, ventilation and longevity. We follow AS/NZS 5139 for installation location, clearances and protection, and as a Level 2 ASP we handle any metering or supply changes the install requires.
