A home EV charger installation takes a licensed electrician 2 to 4 hours on a standard property, but there are several steps before install day that determine whether yours will be straightforward or require extra work.
The process starts with a site assessment, moves through switchboard checks, charger selection and any network approvals, then finishes with mounting, wiring, testing and commissioning. Most homeowners are charging the same day the electrician leaves.
This article walks through every stage of a home EV charger installation so you know exactly what to expect, what your electrician will be looking at, and how to prepare your property. If you are on the Mid North Coast and want a local CEC-accredited installer to handle the full process, contact SolaXs for a site assessment.
The Site Assessment and What Your Electrician Checks
Every home EV charger installation starts with a site visit. The electrician is not just picking a wall to mount the charger on. They are assessing the full electrical path from your meter board to the proposed charging location.
During a site assessment, the electrician will:
- Inspect the switchboard for spare capacity, circuit breaker slots and RCD protection
- Measure the cable run from the switchboard to the charger location, noting whether it goes through walls, under floors or underground
- Check whether your supply is single-phase or three-phase and confirm the maximum available load
- Identify the best mounting position based on where you park, cable length and weatherproofing needs
- Note any obstacles like gas lines, water pipes or structural limitations in the cable path
A proper site assessment takes 20 to 30 minutes. It is the only way to give you an accurate quote, which is why any installer quoting over the phone without visiting your property should raise a flag.
Switchboard and Electrical Readiness
The switchboard is the single biggest variable in a home EV charger installation. A standard Level 2 charger draws 32 amps on a dedicated circuit. Your switchboard needs a spare breaker slot, enough rated capacity for the additional load, and compliant RCD protection.
Australian wiring rules (AS/NZS 3000:2018) require every EV charger to have its own dedicated circuit with no other appliances wired to it. The circuit needs a dedicated RCD and a minimum 6mm² cable for a standard 32A domestic installation.
| Switchboard Scenario | What Happens |
|---|---|
| Modern board with spare slots | Electrician adds a new 32A breaker and RCD. No upgrade needed. |
| Full board, no spare slots | The board needs additional circuit breaker capacity or a sub-board. |
| Older fuse-based board (pre-1990s) | Full switchboard upgrade required before the charger can be installed. |
| Board at maximum rated load | A load management device can throttle the charger to avoid overloading. |
If your home was built before the mid-2000s, budget for the possibility of switchboard work. It is the most common surprise in the process and the reason a site assessment matters.
On the Mid North Coast (Essential Energy network), chargers above 5kW may require a connection agreement with the network distributor. Your installer should handle this paperwork as part of the process. SolaXs manages all network approvals for EV charger installations in our service area.
Choosing the Right Charger for Your Home
The charger itself is only part of the equation, but picking the right one before install day avoids delays. There are two main decisions: the power output and the feature set.
Power Output
Most Australian homes have single-phase power, which supports a maximum 7kW charger. That adds roughly 40 to 45 km of range per hour of charging. For a typical daily commute of 40 to 60 km, overnight charging on a 7kW unit covers it easily.
Three-phase homes can run a 22kW charger, adding around 120 to 130 km of range per hour. Unless you drive 150+ km daily or need fast turnaround between trips, single-phase 7kW is more than enough.
Smart Features
Basic chargers start and stop manually. Smart chargers connect to Wi-Fi and offer features that save you money and make charging easier.
- Scheduled charging to run during off-peak tariff windows
- Solar integration to prioritise charging from your panels during the day
- Load management to throttle the charger when other appliances are drawing power, preventing overload
- Usage monitoring to track how much energy each charging session uses
SolaXs installs a range of EV chargers from brands we trust. We match the charger to your electrical setup, driving habits and whether you have or plan to add solar.
What Happens on Install Day
Installation day is where the plan from the site assessment becomes real. Expect the electrician to be on site for 2 to 4 hours, though jobs with switchboard upgrades or long cable runs may take longer.
Here is the typical sequence:
- Power isolation: the electrician turns off the mains at the meter board. Your power will be off for most of the install.
- Switchboard work: a new dedicated 32A circuit breaker and RCD are installed. If a switchboard upgrade is needed, that happens first.
- Cable run: the 6mm² (or larger) cable is routed from the switchboard to the charger location. This might go through the roof cavity, under the house, along a wall or through conduit.
- Charger mounting: the unit is fixed to the wall at the agreed location, typically at a height that suits the charge cable reaching your vehicle’s port.
- Wiring and termination: the cable is connected to the charger and terminated at the switchboard.
- Testing: the electrician powers the system on and tests the circuit for correct polarity, earth fault protection and insulation resistance.
- Commissioning: if the charger has an app or Wi-Fi features, the electrician helps set it up and runs a test charge.
You will need to be home at the start and end of the installation. The electrician will issue a Certificate of Compliance (or equivalent state document) confirming the work meets AS/NZS 3000.
Connecting Your EV Charger to Solar Panels
If you already have solar panels or plan to add them, your EV charger installation can be set up to charge from solar instead of drawing from the grid. This is where the real savings happen.
A 6.6kW solar system on the Mid North Coast generates around 25 to 30kWh on a good day. A typical EV uses 15 to 20kWh per 100km. That means a single day of solar generation covers 120 to 200km of driving, well beyond most daily commutes.
There are three levels of solar integration:
- Timer-based charging: you manually set the charger to run during peak solar hours (typically 9am to 3pm). Simple but requires you to be home or have a parked car during the day.
- Smart solar diversion: the charger communicates with your inverter and only draws power when excess solar is available. Fully automatic, no intervention needed.
- Battery buffer: a home battery stores daytime solar and the charger draws from the battery overnight. Best for people who drive during the day and charge at night.
SolaXs installs EV chargers alongside solar and battery systems, so the whole setup is designed to work together. Bundling the install also reduces labour costs because the electrician is already on site and the switchboard work overlaps.
Safety and Compliance Requirements
A home EV charger installation is a regulated electrical job. Australian law requires a licensed electrician for every part of it. DIY installation risks fire, electric shock, voided insurance and warranty problems.
The installation must comply with:
- AS/NZS 3000:2018 (Wiring Rules): the overarching standard for all electrical installations in Australia
- Dedicated circuit requirement: the charger must be on its own circuit with no other appliances
- RCD protection: a Type A or Type B residual current device must protect the charging circuit
- Network distributor requirements: Essential Energy (Mid North Coast) may require notification or a connection agreement for chargers above 5kW
- Certificate of Compliance: issued by the electrician after testing, confirming the install meets all standards
Using a CEC-accredited installer adds another layer of confidence. The Clean Energy Council accreditation means the electrician has specific training in EV charger and solar installations beyond standard electrical licensing.
How to Prepare Your Home Before the Installer Arrives
A little preparation on your end makes install day faster and avoids holdups. Here is what you can do before the electrician arrives.
- Clear the area around the meter board and the proposed charger location. The electrician needs unobstructed access to both.
- Move your car out of the garage or carport so the electrician can work freely on the wall.
- Know your Wi-Fi password if the charger has smart features. The app setup happens during commissioning.
- Confirm parking position so the charger cable reaches your vehicle’s charge port. Different cars have the port on different sides.
- Ask about off-peak tariffs with your energy retailer. Some retailers offer EV-specific plans with cheaper overnight rates, and your charger can be set to take advantage of them from day one.
