EV charging · Melbourne

Leave home
full every
morning.

Public fast charging is typically far more expensive per kilometre than charging at home. A properly installed wallbox — matched to your solar and your tariff — lets you charge on your own surplus or off-peak rates.

Why cheap installs go wrong

A wallbox is easy to hang on a wall. Everything behind it is where installs fail.

Most call-backs we attend come down to three things: no load management, the wrong residual current device, and a cable run nobody measured before quoting.

01

No load management

Charge at 32A while the oven and aircon are running and the main breaker trips. The fix is a CT clamp, not a bigger supply.

02

Wrong RCD fitted

EV circuits can inject DC fault current. A standard Type A device won't clear it — the install is non-compliant from day one.

03

Priced before the site check

Online quotes assume a 5m run and a healthy switchboard. The variation arrives on install day, when you can't say no.

Charge speed

Same car, same night.
Three very different mornings.

Empty to 80% on a 60kWh battery — 45kWh of energy. Watch how far each option gets before you wake up.

The honest answer
6.4 hrs
7kW fills an empty-ish car before morning

Almost nobody arrives home empty. A typical Melbourne day is 40km — about 90 minutes on a 7kW wallbox. 22kW is for two-car households, not bragging rights.

Load management

Turn the house on.
Watch the charger step back.

A CT clamp on the mains lets the wallbox share what's left instead of tripping the main breaker. Switch it off and see what a cheap install does.

Design decisions

Six choices behind
a charge that just works.

Each one is decided on site, before a price is issued.

01

Solar-matched by default

The charge rate follows your surplus so the car absorbs export instead of shipping it out at feed-in rates.

Surplus tracking
02

Dynamic load, not guesswork

The charger throttles when the house draws hard — no nuisance trips, no supply upgrade.

CT clamp
03

Off-peak windows preset

We configure your retailer's cheapest hours at commissioning so you never think about it again.

Tariff aware
04

Correct RCD type

EV circuits need DC fault detection. We fit Type B or Type A with 6mA DC — never a plain Type A.

Route surveyed before quoting

The cable run drives the price. We photograph and measure it up front so the number doesn't move.

06

Ready for the second car

Switchboard capacity and conduit are left with headroom so adding a second wallbox is a one-hour job.

Our commitment

Solar-matching and off-peak windows are configured at commissioning — so the charger follows your tariff from the first session, not the factory defaults.

Questions

Charging,
answered plainly.

No. A 7kW single-phase wallbox adds roughly 40km of range per hour, which covers an overnight charge for almost every driver. Three-phase is worth it if you have two EVs or drive long distances daily.
