AC Charging at Home
Most home EV chargers provide AC charging. The vehicle's onboard charger determines how much AC power it can accept, so fitting a higher-rated wall charger does not necessarily increase the actual vehicle charging rate.

EV Charger Cost and Charging Speeds in Adelaide
The practical home charging rate is set by the vehicle, charger and property together. Compare 7 kW, 11 kW and 22 kW AC charging, then confirm the installation scope before choosing a charger.
Installation cost
How Much Does EV Charger Installation Cost in Adelaide?
The final cost depends on the charger model, vehicle compatibility, single-phase or three-phase supply, cable route, switchboard capacity, protection equipment, parking location and any load-management or solar-charging requirements. A written quote should clearly state the charger model, charging capacity, cable route, electrical protection, installation inclusions, exclusions and any switchboard work. PDG Energy does not publish a universal installed price because these property-specific requirements can materially change the final scope.

Home AC Charging vs Public DC Fast Charging
Home charging and public rapid charging use different equipment and are not directly comparable by the number printed on a charger.
DC Fast Charging
Public DC fast chargers work differently and may charge at much higher rates than a home charger. Their output, the vehicle battery condition and the vehicle's DC charging capability determine the public charging result.
Charging-time guide
How Long Does It Take to Charge an EV at Home?
Use this as a simple planning estimate, not a guaranteed result:
Battery capacity in kWh actual charging rate in kW = approximate charging time
Actual time can vary because of the vehicle, battery charge level, charging losses, charger settings and household electrical capacity.
Quote factors
7 kW vs 11 kW vs 22 kW Home Charging
These factors help make quotes comparable. The applicable detail depends on your property and selected system.
7 kW home charging
Often considered for suitable single-phase homes. Actual charging speed depends on the vehicle, charger settings and final electrical supply.
11 kW home charging
Usually requires suitable three-phase supply and a vehicle that supports 11 kW AC charging.
22 kW home charging
Requires suitable three-phase infrastructure, available electrical capacity and a vehicle capable of accepting 22 kW AC charging.
Actual rate can be lower
The charger nameplate is not a promise of the vehicle charging rate. The onboard charger, supply, household load and settings all affect what the vehicle receives.

Solar, Switchboard and Installation Scope
The final design should match the way the vehicle is parked, charged and used, not only its connector or the charger nameplate.
Can I Charge My EV With Solar?
Yes. Scheduled overnight charging can suit a regular charging window, while solar-surplus charging can respond to generation that remains after household loads. When household demand increases or solar output falls, the available solar charging rate can change. Charger settings, solar monitoring and any battery plan need to be considered together.
Do I Need a Switchboard Upgrade?
Not every property needs one. Available capacity, protection, cable route, phase arrangement and the load assessment must be checked. The review also considers existing solar, battery storage, air conditioning, cooking and other major loads so the charger is integrated safely into the property.
What Is Included in an EV Charger Installation?
The written scope identifies charger mounting, a dedicated circuit, cable route, electrical protection, testing and commissioning. App setup or solar-aware configuration is included where relevant to the selected charger and agreed installation scope. Any switchboard work, exclusions and site conditions should be stated clearly.
What Information Is Needed for a Quote?
Send the vehicle make and model, parking location, charger preference, switchboard photos, solar and battery details, and the charging behaviour you want. This allows PDG Energy to assess the supply, cable route, electrical protection, load management and final installed scope.

Guide FAQ
Questions to Ask Before You Decide
For a confirmed scope, move from this guide to the relevant core installation service.
Is a 7 kW charger enough for my EV?
It may be, particularly where the vehicle can charge during a regular overnight window and the property has suitable single-phase supply. The vehicle battery, onboard charger and driving pattern should be considered before choosing a rate.
Does a 22 kW charger charge every EV faster?
No. A vehicle only accepts the AC rate supported by its onboard charger. A 22 kW charger also needs suitable three-phase infrastructure and available electrical capacity.
Can I install an EV charger with single-phase power?
Yes, a suitable single-phase installation can support an EV charger. The practical charging rate and installation scope depend on the property, switchboard, cable route, vehicle and load assessment.
Can I charge from excess solar power?
Yes, with a compatible solar-aware charging approach. Solar-surplus charging responds to available generation after household loads, so the charging rate can vary through the day.
Do I need a switchboard upgrade?
Not every property does. Available capacity, protection, cable route, phase arrangement and the load assessment determine whether changes are needed.
Can an EV charger be installed outdoors?
Often, subject to the selected charger rating, mounting location, cable route, weather exposure, access and final electrical design.
How long does installation take?
The installation time depends on the final scope. Charger location, cable route, switchboard work, supply arrangement and any required approvals are confirmed before scheduling.
Can I add battery storage later?
Yes, it can be planned as a future upgrade. The charger, existing solar, battery path and household load should be reviewed together so the final design remains practical.
