EV Charger Installation in Point Cook

Unlike Altona or Werribee, we almost never condemn a Point Cook switchboard. Estate boards built from 2003 onward have breakers, RCDs and usually a spare way or two. The safety conversation is short.

The capacity conversation is not. A typical Point Cook home already carries ducted reverse cycle, an electric oven and cooktop, a heat pump or electric hot water service, and in a growing number of homes a battery inverter. Adding 32A of continuous charging on a single phase supply can take total demand past what the main switch and consumer mains were designed for. We calculate the maximum demand rather than guessing.

With solar already installed, a smart charger with a current transformer on the main supply can put surplus generation into the car rather than exporting it for a few cents. On a Point Cook roof with 6.6kW or more, midday surplus is often 3 to 5kW, which is real charging.

Where there is also a battery, the priorities have to be set deliberately or the three systems fight each other. Left alone, a battery will happily discharge into the car overnight, which achieves nothing except cycling the battery. We configure the charger to take surplus solar during the day and to draw from the grid on an off peak schedule overnight, leaving the battery to cover the house in the evening peak.

Point Cook has a lot of double storey estate homes with narrow side setbacks and limited eaves. Where the board is in the garage, none of that matters. Where the board is on the far side of the house, the run has to get there, and the modern hip and valley roof structure with short unbroken runs makes a roof space route slower than it looks from the street.

We walk the route at the quote. In most cases the answer is a run through the garage ceiling or along an internal wall cavity, which is clean and quick. Occasionally the honest answer is surface conduit down a side wall, and we will show you exactly where it will sit before you agree to it.

Almost every Point Cook estate home was built single phase on the Powercor network. That means the practical charging ceiling is 32A, about 7.4kW, giving 40 to 50km of range per hour. For a household doing 50km a day that is a two hour top up, not an overnight problem.

People ask about 22kW because it appears on the spec sheets. Getting there in a Point Cook estate means a distributor supply upgrade, new consumer mains and a new board, and most cars cap their onboard AC charging at 7kW or 11kW anyway. If you have two EVs and both need full charges nightly, it can be worth the conversation. Otherwise it is not, and we will say so.

The better spend for a two EV Point Cook household is usually a second charger with dynamic load sharing between the two units. They split whatever current the supply can spare, automatically, without either car waiting for the other and without touching the incoming supply. It is a fraction of the cost of a phase conversion and it works on the switchboard you already have.
