Who solar-aware home charging suits
Yes, a home with rooftop solar can charge an EV from its own generation. A solar-aware charger watches what the panels produce and what the house uses, then sends the spare power to the car instead of exporting it. It suits Melbourne households whose car is parked at home during daylight.
How charging from the roof works
On a sunny day the charger reads a sensor near the switchboard or data from the inverter and adjusts its charge rate to match the surplus. When cloud rolls over, it can slow down, pause or top up from the grid, depending on the mode you choose in the app.
Off-peak tariffs and smart scheduling
Not every day is sunny, particularly through a Melbourne winter. Smart chargers such as the myenergi Zappi and Evnex units can be scheduled through an app, so overnight charging falls inside the off-peak or time-of-use window your electricity plan offers.
Why the smart or basic decision matters
A basic charger simply delivers power whenever the car is plugged in. That works if you rarely have spare solar or always charge at night. A smart charger costs more up front, but it follows your panels and tariff automatically, so its value depends on how much generation you currently export.
Will it work with your existing solar and battery?
Most solar-aware chargers measure power at the grid connection, so they generally sit alongside an existing inverter rather than replacing it. A home battery adds a priority choice: whether the car or the battery fills first. Inverter brand, battery model and single or three-phase supply all shape the right charger.
Safety certificate for a solar charger install
Whichever charger you pick, the Registered Electrical Contractor or licensed electrician doing the job must issue a Certificate of Electrical Safety and give you a copy. Keep it with your solar system paperwork, since both relate to the same switchboard.
Next step for solar EV charging
Note your solar system size if you know it, the inverter brand, any battery and your suburb. After that, request a quote here and a licensed and insured local contractor can follow up on the solar side. Also decide whether daytime solar charging or overnight off-peak charging matters more to you, since that sets the modes you will rely on.
Solar EV Charger Installation Services We Offer
✓Charger for an Existing Solar System
A solar-aware charger added to a home with panels already on the roof, using a sensor or inverter link to divert spare generation to the car.
✓Solar and Home Battery Charging
Setting charging priorities so the car and the battery share surplus solar in the order that suits how you drive and when you are home.
✓Smart Tariff Charging
App scheduling that keeps charging inside off-peak or time-of-use windows on days when the panels cannot cover the car.
How it works
- 1
Note your system details
Write down the solar system size, inverter brand and any battery model so the charger can be matched to how your home generates and stores power.
- 2
Site check
The installer looks at the switchboard, the cable run to the parking spot and where a sensor or monitoring link needs to sit.
- 3
Install and set up
The charger goes on its own circuit, solar sensing is connected and the app is configured with your preferred charging modes and tariff windows.
- 4
Certificate and handover
You receive a Certificate of Electrical Safety and a walk through of solar, scheduled and boost modes so you can switch between them.
