With home EV charging costing roughly half as much as public rapid charging, installing an EV charger at home has become one of the smartest investments for electric vehicle owners. At Avery Solar & Electrical, we specialise in helping homeowners make the switch with professional, reliable EV charger installations across the Blue Mountains, Penrith, Hawkesbury and surrounding regions. As electric vehicles become more common, home charging is no longer just a convenience—it’s a necessity for cost savings and peace of mind.
This guide covers everything you need to know—from charger types and installation costs to electrical upgrades and smart solar integration—so you can make informed decisions about your EV charging setup.
Key Takeaways
- Home EV chargers offer the most cost-effective and convenient charging, costing up to 50% less than public charging.
- Installation typically ranges from $2,000–$2,500, depending on the charger and your home’s electrical setup.
- Single-phase 7kW chargers add 35-40km of range per hour, while three phase chargers can provide up to 130km per hour
- Older homes may require switchboard upgrades for safe operation.
- Solar integration further reduces costs and environmental impact.
- Apartment installations require strata approval and planning.
Why Install a Home EV Charger?
Cost Savings
Charging at home can be as low as $0.10–$0.15 per kWh on off-peak tariffs, compared to $0.40–$0.60 per kWh at public chargers. For example, charging a Hyundai Kona Electric with a 64kWh battery costs around $7 overnight at off-peak rates—translating to daily running costs of just $2–$3.
Ultimate Convenience
No more queueing at public stations. Plug in at night and wake up to a fully charged EV every morning.
Faster Charging
Standard power points offer just 10–12km of range per hour. A dedicated 7kW charger can triple that, while a 22kW unit (with three-phase power) delivers even more—if your vehicle supports it.
Increases Property Value
EV chargers are quickly becoming as sought-after as solar panels and NBN connections for property buyers.
Types of Home EV Chargers
Standard Power Point (2.3kW)
-
Adds 10–12km range per hour
-
Best used for emergencies or very light daily driving
Single-Phase Wallbox (7–7.4kW)
-
Adds 35–40km range per hour
-
Ideal for overnight charging
-
Supports smart features and solar integration
Three-Phase Wallbox (11–22kW)
-
Adds 50–130km range per hour (vehicle dependent)
-
Requires three-phase power, available in some homes or upgradeable
Smart & Solar-Compatible Chargers
-
WiFi/Bluetooth control
-
Scheduled charging during off-peak hours
-
Solar optimisation (e.g., Myenergi Zappi)
Weather-Resistant Options
Outdoor installations require chargers with appropriate IP65 or higher ratings to resist moisture and dust. Many modern ev home charger units feature compact, weatherproof designs—for example, the Tesla Gen 3 Wall Connector measures just 345mm × 155mm × 110mm while maintaining full outdoor durability.
Choosing the Right Location for Installation
-
Garage or carport: Safest and most secure
-
Close to switchboard: Minimises cabling costs
-
Consider port location on your vehicle to avoid awkward cable runs
-
Plan ahead for solar or dual charger setups if needed

Understanding your home’s electrical capacity and requirements is crucial for a safe, compliant installation.
-
Most homes use single-phase power, which is suitable for most EVs.
-
All EV chargers need a dedicated circuit installed by a licensed electrician.
-
Homes built pre-1990 may need switchboard upgrades to support modern electrical loads.
Switchboard Upgrades
-
May cost $1,000–$2,000
-
Ensure compliance with AS/NZS 3000 electrical standards
Installation Process and Timeline
-
Site inspection & quote
-

-
Installation (usually 2–6 hours)
-
Testing & user training
-
Warranty issued (typically 2–5 years on hardware, 1–2 years on workmanship)
