Solar and EV Charger Integration.

Connect Your Solar System to Your EV Charger

If you've already got rooftop solar and you're driving an electric vehicle, you're probably leaving money on the table every day. Solar and EV charger integration links your photovoltaic (PV) system to your home charger so the car draws on surplus solar generation rather than pulling straight from the grid. In Carseldine and the surrounding northern Brisbane suburbs, where many homes have had solar panels for five or more years, this is one of the more practical upgrades we carry out.

What the Work Actually Involves

This is not a simple cable run. The job typically includes:

• A solar-aware EV charger or charge controller that reads your inverter's export signal and adjusts charging speed in real time
• Wiring between your inverter (or solar gateway) and the EV charger, often using a CT clamp (current transformer) or a direct communication link depending on your inverter brand
• Configuration of the charger's "solar mode" or "eco mode" so it throttles up when surplus solar is available and throttles back when it's not
• Testing under live solar conditions to confirm the system responds correctly
• A dedicated circuit from the switchboard to the charger, if one isn't already in place

The specific equipment depends on what inverter you already have. Fronius, SolarEdge, Goodwe, and Sungrow are common across Carseldine and Albany Creek. Some of these communicate directly with compatible chargers over a local network connection; others rely on CT clamp monitoring. We'll assess your existing setup before quoting.

When You'd Need This Service

You need this service if:

• You have an existing solar system and you've just bought or are about to buy an EV
• You've had a standard EV charger installed but it runs on a flat tariff with no awareness of when solar is generating
• Your energy bills have increased since getting the EV despite having solar on the roof
• Your inverter app shows consistent daily export to the grid between roughly 9am and 3pm, which is generation you could be using to charge instead

There's no particular season to act, but it's worth noting that solar export in Carseldine is typically highest during spring and early summer before the cloud cover of storm season reduces daily output. If you're buying an EV between August and October, getting the integration set up before Christmas makes good sense.

What It Costs in Brisbane

For a solar and EV charger integration in this part of Brisbane, expect to pay somewhere in the range of $1,800 to $4,500 depending on several factors:

• Your inverter compatibility. A well-supported brand with an open API is easier to integrate than an older or generic unit.
• Whether you need a new EV charger. If you already have a solar-compatible charger, we're doing the commissioning and wiring. If you need a new charger supplied as part of this job, that's a significant portion of the cost.
• Cable run length. A charger in a garage directly below the switchboard costs less to wire than one in a carport at the far end of a Queenslander-style home on stumps.
• Switchboard condition. Older boards, common in homes built before the 2000s across Bald Hills and Bracken Ridge, sometimes need a circuit upgrade before we can safely add the EV load. We'll flag this upfront.

What's Included in the Quote

Our quotes for this service include labour, the CT clamp or communication hardware, any conduit and cabling needed, charger configuration, and a test under real solar conditions. What's typically not included: a new solar inverter if yours is incompatible, switchboard upgrades (quoted separately if needed), or permits beyond standard electrical notification requirements.

We'll tell you clearly what's inside and outside the quote before any work starts.

Is This the Right Service for Your Property?

It makes sense if your solar system is in good working order, your inverter is less than about ten years old, and you're regularly exporting more than 2-3 kW to the grid during the middle of the day. If your panels are degraded or your inverter is nearing end of life, it may be worth addressing that first so you're integrating with a reliable system.

If you're not sure how much you're exporting, your inverter app or your electricity retailer's portal can show you. A daily export of 6-10 kWh is common on a typical 6.6 kW system in this part of Brisbane, which is enough to meaningfully charge most EVs over a few hours.

A Note on Qualifications and Safety

All electrical work we carry out is performed by licensed electricians and complies with AS/NZS 3000 wiring standards. EV charger installation and solar-connected work requires a licensed electrician in Queensland; it is not a DIY job and your home insurance may not cover damage from unlicensed electrical work. We provide a Certificate of Test on completion.
