EV charging runs through five stages: grid or solar, switchboard, wallbox, onboard charger, battery. The slowest stage sets your charge rate.
Most Brisbane homes run single-phase power. A 32A circuit delivers 7.4kW.
If your car’s onboard charger only accepts 7.2kW, a 22kW three-phase wallbox charges at the same speed as a 7kW unit, for more cost and complexity.
Brodie Rix puts it plainly: most customers ask for 7kW because that’s the number they’ve heard. Half don’t need three-phase power at all.
About 90% of Queensland homes are single-phase. A 4.6kW charger suits drivers under 50km a day; 7.4kW suits heavier use.
Installing an EV charger in Brisbane is not just a matter of running a cable. Queensland’s Energex has rules that govern how much current a home charger can draw from the network, and they changed in April 2024.
Under QECM Version 4, any single-phase EV charger drawing above 20A requires Active Device Management (ADM). That covers the common 7.4kW/32A charger.
It does not mean you cannot install one. It means there are specific connection pathways your electrician must follow.
There are three compliance pathways, and your electrician picks the right one for your home:
Your electrician files the Electrical Work Request with Energex. No extra cost, no added delay. Choosing the wrong pathway, especially the economy tariff with solar, means your charger and your panels work against each other.
BRIX Electrical and Air’s residential electrical team handles EWR lodgement on every EV installation. You don’t manage that process yourself.
Three brands cover most EV charger installations BRIX Electrical and Air handles in Brisbane. The right one depends on what’s already running in your home.
SolaX
Default for homes without a brand preference. Handles load limiting, scheduling, and solar surplus charging. Most standard single-phase installs at BRIX use SolaX.
Sungrow
BRIX’s main solar and battery brand. If your home already runs Sungrow solar panels or battery hardware, a Sungrow charger fits the same app and ecosystem.
Sigenergy
Suits homes already on a Sigenergy system. Gateway, battery, solar, and charger run through one app, tightly integrated.
If you have existing solar, the brand question matters more than it seems. Solar divert, using surplus solar before drawing from the grid, only works when the charger is on the correct Energex pathway with CT metering installed. BRIX’s solar services team can confirm compatibility before you order.
Considering a battery too? Start with solar battery installation advice first, a battery bought mainly to charge your EV overnight rarely makes financial sense on its own.

A two-storey Brisbane home needed a charger installed on the upper level. Cable routing ran through an existing hallway light between floors, avoiding the need to open walls. BRIX Electrical and Air installed a dedicated 32A circuit with CT metering behind the finished wallbox.
Nameplate: 32A, 7.2kW. Charging starts automatically when solar surplus is available during the day.
A home already running Sigenergy solar and battery hardware. Adding the Sigenergy EV charger brought the gateway, battery, solar inverter, and charger into one platform. The app shows charging at 20A / 4.8kW, deliberately set below the 32A maximum to stay within the home’s load capacity without a switchboard upgrade.
The customer supplied the Tesla Wall Connector. The existing three-phase switchboard was full, with no room for an additional circuit. BRIX Electrical and Air designed and installed a dedicated sub-board to house the EV circuit.
The switchboard upgrade was completed alongside the EV installation, with full documentation and Energex compliance lodged.
Before recommending anything, BRIX Electrical and Air works through six questions with every EV customer: which car, how much daily driving, single- or three-phase supply, existing solar or battery, which smart features matter, and budget and support expectations.
The site visit comes next. BRIX Electrical and Air runs a documented process from site visit through design and quote, job documentation, and install, test, and handover. Fourteen people. One point of contact throughout. Licence 88304, ARC AU068598.
This is not a sales process. It is an engineering process. The six questions exist because a charger that does not suit your car, your supply, or your solar setup is a waste of money, and sometimes a compliance problem.

A standard 7kW single-phase EV charger, fully installed, ranges from $1,200 to $2,500. That range reflects differences in hardware, cable routing complexity, and whether CT metering is included. It reflects pricing observed across licensed installers in the Brisbane market.
If your switchboard needs upgrading before installation can proceed, add $1,200 to $2,500 for that work. A solar-aware smart charger, such as the Zappi, typically runs $2,200 to $3,000 installed. A three-phase 22kW unit starts at around $2,400 and rises with installation complexity.
Your actual quote depends on your home’s specific circumstances. BRIX Electrical and Air will not recommend a switchboard upgrade unless the site visit confirms it is needed.
If you are planning EV charger installation in Brisbane or Ipswich, the starting point is a site visit, not a product catalogue. The right charger for your home depends on your car, your supply, your solar setup, and your daily driving.

No. Most Brisbane homes run on single-phase supply, and a 7.4kW single-phase charger covers the majority of residential EV charging needs. Three-phase is only necessary if your car’s onboard charger accepts 11kW or above, or if you already have three-phase power and want to use it.
About 90% of Australian homes are single-phase.
Under QECM Version 4 (April 2024), single-phase EV chargers drawing more than 20A require Active Device Management. A standard 7.4kW / 32A charger exceeds that threshold. Your electrician handles the compliance pathway, either an economy tariff circuit or an ADM-approved smart charger on your main tariff.
You do not manage that process yourself.
That depends on your car’s onboard charger, not just the wallbox. If your car accepts a maximum of 7.2kW, a 22kW unit charges it at the same speed as a 7kW unit. A 22kW three-phase charger makes sense for vehicles that accept 11kW or 22kW AC and homes with three-phase supply.
For most Brisbane homeowners, a 7kW single-phase unit is the right choice.
Yes, but only on the correct Energex compliance pathway. Solar divert charging, where your wallbox uses surplus solar before drawing from the grid, requires CT metering and a charger on the primary tariff with ADM. The economy tariff pathway uses a separate circuit and cannot respond to solar generation.
BRIX Electrical and Air’s solar team can confirm compatibility before installation.
Not always. It depends on your switchboard’s current capacity and the number of circuits in use. Older switchboards with ceramic fuses almost always need upgrading first.
Modern switchboards with spare circuit capacity often do not. The site visit determines this. BRIX Electrical and Air will not recommend a switchboard upgrade unless it is needed.
