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.

Load balancing can reduce EV charging speed when other high-power appliances are running (air conditioning, oven, hot water), helping prevent switchboard overload — especially useful in older Australian homes with limited electrical capacity.

OCPP support enables integration with third-party energy management systems, tariff optimisers, and smart home platforms — providing flexibility as your setup evolves.

With IP54 weather rating, this charger is suitable for garage, carport, or driveway installation. Your installer should confirm the best mounting location for your home.

For safety and warranty coverage, EV charger installation must be performed by a licensed Australian electrician. Always get a written quote and confirm compliance with AS/NZS 3000.
