A straightforward installation of a customer-supplied EV charger can cost as little as $600, provided the charger is installed near the switchboard and there are no switchboard, electrical-capacity or cable-route complications.

The final cost depends on the charger, distance from the switchboard, required electrical protection and whether additional cabling, trenching or switchboard upgrades are needed.

Send us photos of your switchboard and proposed charger location, along with the charger’s model details, for an initial estimate.

Yes. We can install many customer-supplied chargers purchased directly from a manufacturer, vehicle dealership, electrical supplier or retailer such as Bunnings or Mitre 10.

Before purchasing, send us a link or the model details. We can check whether the charger is suitable for use in New Zealand and compatible with your vehicle, switchboard, electrical supply and solar system.

Renew Electric brings specialist solar knowledge to every EV charger installation. With more than 1,200 solar installations completed over the past eight years, we understand how EV chargers interact with solar panels, batteries, inverters and home energy-management systems.

We have practical experience with Sigenergy, Tesla, Fronius and other leading solar and battery systems, helping ensure your charger is compatible with your existing equipment and configured correctly.

Yes. We can provide a complete supply-and-installation package based on your vehicle, home electrical supply, solar system and budget.

This can include the charger, dedicated electrical circuit, required protection, installation, testing, commissioning and electrical certification.

We install many popular EV charger brands available in New Zealand, including:

• Tesla Wall Connector

• Evnex

• Fronius Wattpilot

• Sigenergy

• Wallbox

• Schneider Electric

• DETA

• DeWALT

We can also assess other brands. The right charger will depend on your vehicle, home, solar equipment, charging requirements and budget.

Most homes can accommodate an EV charger, but the switchboard and available electrical capacity should be assessed first.

Your installation may require a dedicated circuit, additional protection, switchboard alterations or dynamic load management. We will identify any requirements and explain them clearly before work begins.

Charging speed depends on the charger, your vehicle’s onboard charging capacity and whether your home has single-phase or three-phase power.

A typical single-phase home charger can provide up to approximately 7 kW. Some three-phase homes and compatible vehicles can support higher charging rates. We will recommend a suitable option after assessing your home and vehicle.
