Fronius Wattpilot EV Charger Installation Sydney

How the Fronius Wattpilot Uses Your Solar Power

Most EV chargers draw from the grid at a fixed rate with no consideration of whether your solar panels are producing at the time. The Wattpilot Flex works differently: a CT clamp is fitted at your switchboard to monitor solar generation and household consumption in real time. The charger then adjusts your EV's charging rate in precise increments to match whatever surplus solar is available at that moment.

If a cloud passes over and solar output drops, the Wattpilot reduces the charge rate automatically. When the sun returns, it ramps back up. The result is that as much of your car's charge as possible comes from your own roof rather than the grid, which is particularly valuable if you're on a low feed-in tariff and would otherwise be exporting that surplus for little return.

The Wattpilot works with any solar inverter brand via the CT clamp approach. When paired with a Fronius inverter, the integration is even tighter: both devices communicate through the Solar.wattpilot app, giving you a unified view of solar production, home consumption, battery storage (if installed), and EV charging from a single dashboard.

Available Models: 11 kW and 22 kW

The Wattpilot Flex Home is available in 11 kW and 22 kW versions. Most Sydney homes with single-phase power will use the 11 kW model, which is more than sufficient for overnight charging and effective solar integration. Homes with three-phase power can install the 22 kW version for significantly faster charge sessions when needed. Both models use a 6m Type 2 cable and are controlled through the same Solar.wattpilot app.

Our team will confirm the right model during the site assessment, factoring in your switchboard capacity, your vehicle's onboard charger rating, and your solar configuration.

Frequently Asked Questions

How much does Fronius Wattpilot installation cost in Sydney?

The Fronius Wattpilot Flex Home retails at approximately $1,800 to supply. A standard installation on an existing switchboard with adequate capacity and a straightforward cable run typically adds $300 to $600 in labour. We provide a written upfront quote before any work begins, so there are no surprises on the bill.

Does the Fronius Wattpilot work with my existing solar inverter?

Yes. While the Wattpilot Flex integrates most tightly with Fronius inverters through the Solar.wattpilot app, it uses a CT clamp to monitor energy flows and is fully compatible with any solar inverter brand. You do not need a Fronius inverter to benefit from solar surplus charging.

Do I need three-phase power to install the Fronius Wattpilot?

No. The Wattpilot Flex is available in both single-phase (11 kW) and three-phase (22 kW) versions. Most homes on the Northern Beaches and North Shore have single-phase power, which suits the 11 kW model well. We confirm the right configuration during your site assessment.

Is a licensed electrician required to install the Fronius Wattpilot?

Yes, professional installation by a licensed electrician is required in Australia. All Plateau Electrical work is carried out by fully licensed and insured electricians, in compliance with Australian Standards and the relevant New South Wales wiring regulations.
