Charging an electric vehicle at home is straightforward, but the right setup depends on your car, your switchboard and your supply. Daly & Co Electrical install EV charging for homes, workplaces and rural properties across Perth’s southern and south-eastern suburbs, and we’ll tell you what your site can actually support before you buy a unit.
Level 1 is the cable that came with your car, plugged into an ordinary power point. In Australia that’s 230V at 10 amps — roughly 2 to 2.4kW, adding about 10 to 15km of range per hour. Left plugged in overnight, that’s 100 to 150km.
It’s fine for a plug-in hybrid, a second car or a short commute. The catch is that it runs a standard household circuit at close to its full rating for hours at a time, which is not what most domestic wiring was designed for. We recommend a dedicated, RCD-protected circuit and a checked outlet rather than an extension lead or a power point shared with the fridge.
Best for: plug-in hybrids, low daily kilometres, renters, or a stopgap while you decide on a permanent setup.
A dedicated wall-mounted charger, and the right answer for most Perth homes. Single-phase units run up to 7.4kW (32 amps), adding roughly 40km of range per hour — enough to fill almost any EV overnight. If your home has three-phase supply, 11kW and 22kW units add roughly 60 to 120km per hour.
The installation is a dedicated circuit back to the switchboard with its own protection and isolator, plus the charger mounted where the car actually parks and on the side its charge port is on.
Before we quote, we check your switchboard, your supply type and your maximum demand. In Western Power’s network, a standard connection in the Perth metro area is 63 amps single-phase or 32 amps per phase on three-phase, and adding a charger has to stay inside that. Where it doesn’t, the options are a smart charger with grid import limiting, or an application to Western Power for an upgraded connection. We’ll tell you which one you’re looking at before you commit to a unit.
Best for: full electric vehicles, daily driving, two-EV households, workplaces and small fleets.
DC fast charging bypasses the car’s onboard charger and feeds the battery directly, which is why it’s fast — typically 25kW to 350kW, taking most EVs from 10 to 80 percent in 20 to 40 minutes. Australia uses the CCS2 connector as the standard.
This is commercial infrastructure rather than something you put in a home garage. It needs three-phase supply at a scale most sites don’t have, usually a dedicated network connection and sometimes a transformer, along with civil works for the pad, bollards and cable management.
If you’re a fleet operator, workplace, retail site or service station considering DC charging, we can assess what your site’s existing supply can support and what a network upgrade would involve, so you have a realistic picture before going to design.
Best for: fleets, workplaces, retail and hospitality sites, destination charging.
A carport with a solar array on the roof, charging the car parked underneath. It shades the vehicle, generates power at the point where the car sits, and shifts charging away from grid electricity onto your own generation.
We handle the electrical side — the array, the inverter, the charger and the switchgear that ties them together. Paired with a solar-diverting charger, the unit can be set to charge only from surplus solar, so the car takes energy that would otherwise be exported at a low feed-in rate. Most owners run it in a mixed mode: solar-only during the day, topped up from the grid overnight if the car needs to be ready by morning.
Worth knowing before you plan one: the carport structure itself is a building matter and usually needs approval from your local council, and the framing has to be designed to carry the array’s wind loading. We work alongside your builder on that side of it.
On properties with no grid connection, or a connection too limited to add a charger, EV charging has to be designed around what the system can actually deliver. We work on rural and semi-rural blocks around Roleystone, Karragullen, Bedfordale and Pickering Brook where standalone power systems are common.
The design question is generation and storage rather than charger size. How much solar, how much battery, whether there’s a generator for backup, and what the car’s draw does to the rest of the household load across a run of cloudy winter days. In practice most off-grid installs use a smart charger with adjustable current, set to charge from surplus once the house battery is full, so the car never competes with the fridge and the pump.
We can assess an existing standalone system to see what it will support, or design EV charging into a new one from the start — which is always cheaper than retrofitting it later.
Every installation is carried out by a licensed electrician, tested, and issued with an electrical safety certificate. All our electrical work carries a 3 year warranty.
Call 0404 241 051 or send an enquiry, and tell us your car, your suburb and roughly where the car parks. That’s usually enough for us to point you at the right option.
