Electric vehicles are becoming more popular across Bayside and South East Melbourne, and homeowners are now looking for safe, fast and reliable ways to charge at home. A dedicated EV charger gives you quicker charging, better safety and much more convenience than a standard power point.
Here is everything you need to know before installing one.
Why You Need a Dedicated Circuit
An EV charger draws a significant amount of power for long periods of time. This is why it must be installed on its own dedicated circuit by a qualified electrician.
A Dedicated Circuit Ensures
- Safe operation without overloading existing circuits
- Faster and more consistent charging
- Protection from tripping other circuits in the home
- Compliance with Victorian electrical rules and standards
Using a regular power point is extremely slow and should only be used as a temporary backup. A dedicated circuit with proper cabling, an isolator and a quality charger gives your vehicle the safest and fastest charge.
Single Phase vs Three Phase Charging
Most homes in Melbourne have single phase power, but many newer or renovated homes have access to three phase. Your available supply makes a big difference.
Single Phase Charging
- Common in most residential streets
- Typical charging rate of 7 kW
- Adds roughly 30 to 40 kilometres of range per hour
- Suitable for overnight charging for most drivers
Three Phase Charging
- Allows charging rates up to 22 kW depending on the charger
- Adds up to 120 kilometres of range per hour
- Perfect for larger EV batteries or multiple vehicles
- Future proof option if you plan to keep your EV long term
Single phase is completely fine for everyday use and works well with brands like Tesla, Zappi, Evnex, Ocular and Wallbox.
Three phase charging requires a three phase switchboard and available supply from the street. If your home already has three phase, you are in a great position for faster charging.
EV Chargers That Work Well With Solar
If you have solar or plan to install it, choosing the right charger can significantly increase your savings.
Zappi
One of the most popular options for solar homes. It can charge directly from excess solar, limit grid use and even prioritise green energy. Perfect for homes across Bayside where solar is common.
Evnex
A New Zealand and Australian favourite that works well with time of use tariffs, smart charging schedules and solar integration. Clean look, very easy to use and great for homeowners wanting data and tracking.
Tesla Wall Connector
Simple, reliable and perfect for Tesla owners. While it does not directly control solar, it can still work well alongside smart energy systems.
Ocular
Strong budget friendly choice with good reliability and simple operation. Some models support load management and solar features.
Benefits of Solar Linked Charging
Where to Position Your EV Charger
Good placement makes your charging setup safer and easier to use.
Ideal Locations
- Inside the garage
- On an external wall close to your driveway
- As close as practical to your switchboard to reduce cable length
- Away from areas exposed to heavy rain or direct sprinkler spray
A neat installation with tidy conduit or cable management keeps your home looking clean and professional.
Important Safety Considerations
- A weatherproof isolator must be installed near the charger
- Cable sizing must match the charger rating
- Chargers must be installed according to manufacturer instructions
- Regular testing ensures safe operation
- Older switchboards may need upgrades before installation
Having a licensed electrician check your switchboard is essential before any EV charger is installed.
How Long Does It Take To Charge an EV?
Charging time depends on:
- Your vehicle battery size
- Single phase or three phase supply
- The kilowatt rating of the charger
- How low the battery is when you plug in
Most homeowners with single phase charging can fully recharge overnight with ease.
Should You Upgrade to Three Phase Power?
You might consider a three phase upgrade if:
- You want the fastest possible charging
- You have a large EV battery
- You plan to own two EVs
- You run a large home with high electrical demand
- You want to future proof your property
A three phase upgrade also benefits electric cooktops, ducted air conditioning and solar inverters.
