Perth battery buyer's guide
WA rebates, Synergy VPP, Western Power requirements and how to choose an installer — read it now or get it by email.

Important information

CEC approval: Every battery shown is CEC-approved, which the federal STC discount requires. A battery system needs an inverter on Synergy's Supported Solutions List to be eligible for the WA Battery Scheme. Other scheme conditions apply. Chemistries without CEC approval, including sodium-ion, cannot be claimed under the STC discount or the WA Battery Scheme. See how the rebates work.
VPP compatibility: Battery Rewards needs an inverter on Synergy's Supported Solutions List too, so check the inverter in any quote against it.
Western Power: Every installation needs Western Power approval. Emergency Solar Management (remote control of your system in a grid emergency) applies to new and upgraded systems of 5 kW inverter capacity or less.

Not sure which suits your home?

Solar Battery Perth's battery matcher asks about your usage, budget and backup needs, then shows the systems that fit. When you want a quote, an installer from our network that covers your area can price them.

Specifications come from the Clean Energy Council approved products register and manufacturer datasheets; Perth estimates use BOM solar exposure data. Independent and free for households. Installers pay us a flat referral fee, never a percentage of your price.
