EV Charger Installation in Toowoomba

So you're looking at getting an EV charger put in. These are the questions Glenn asks first, starting with the one that decides the most.

One main switch and one isolation link means single-phase, which is what most houses have.

Still not sure? Take a photo of the switchboard and the meter box and text it to Glenn on 0489 082 307.

It's the question Glenn gets asked most, and the honest answer is that it depends. How big is the battery? How flat is it when you plug in? How far do you drive each day?

A 32A (7kW) charger puts back roughly 40 to 50km of range an hour. If you drive 60km a day, that's back in the battery in well under two hours. Leave it plugged in overnight and even a big, flat battery gets most of the way there.

So do you really need a "fast charger"? For most people, no. The car sits in the garage all night anyway, and a normal home charger has plenty of time to do its job. If your driving says otherwise, Glenn will tell you.

Until now, anything over 20A on single-phase had to be managed by Ergon, with a control device on the charger or a special tariff. That's why a lot of home chargers, plenty of Glenn's included, were set at 20A.

From 1 October 2026 that's gone. Ergon now lets you connect a 32A (7kW) single-phase charger to your primary tariff, which is your normal power. No control device and no special tariff. On a standard install there's nothing for you to apply for.

What hasn't changed is your house. The charger still has to fit within what your mains cable and switchboard can carry, along with everything else running at the same time. Glenn checks that first. If your supply needs upgrading, that goes through Ergon and they may charge for it. You'll know before anything starts.

And if you've got solar? Short answer, yes. Long answer, it depends. A solar-aware charger takes the excess your house isn't already using and puts it into the car. How much you get depends on the size of your system and whether the car's actually home while the sun's up.

Glenn diagnoses and repairs all the major brands, not just ones he installed.

Breaker trips while charging: usually a ground fault, an undersized circuit, or an RCD on the way out.

Charging won't start: the charger and the car aren't talking, or it's the cable or the settings.

Charging stops partway: overheating protection, a loose connection, or a failing component.

Slower than it should be: supply voltage, tired connections, or the power settings.

Smart features dropping out: usually the network setup rather than the charger.

Fault finding starts at $187 for the first hour, which covers the testing and a straight answer about what's wrong. You get the repair cost before Glenn does any of it.
