Using this charger at home in Australia

This charger supports higher AC charging speeds where both your home's electrical supply and your EV's onboard AC charger allow. Confirm your home's phase support with a licensed electrician, and check your EV's maximum AC charging capability.

Where supported and correctly configured, load management can reduce EV charging power when other household loads increase, helping keep total demand within the configured site limit.

OCPP support allows the charger to communicate with compatible OCPP charging-management platforms. OCPP support by itself does not guarantee integration with a home battery, solar inverter, electricity tariff or every third-party platform.

The manufacturer lists an IP55 enclosure rating for this charger. The final mounting location should follow the manufacturer's installation requirements and be confirmed by the installer.

A dedicated home EV charger should be installed by a licensed electrician. The installer should confirm the circuit design, switchboard capacity, protection requirements and any applicable local electricity-network requirements.
