What is a home EV charger?

A home EV charger is a dedicated charging unit installed by a qualified electrician. It connects your electric vehicle to your home’s electrical supply and can provide significantly faster and more convenient charging than a standard household socket.Depending on your home and vehicle, we can help you select a suitable EV charger and determine whether your existing electrical supply, switchboard and cabling can support it.

Why install an EV charger at home?

Charging at home means your EV can be ready to go when you are. A properly installed charger also gives you greater control over when and how your vehicle charges.

Benefits include:

• Convenient charging: Plug in at home rather than visiting a public charger.
• Faster charging: A dedicated charger can charge your EV much faster than a standard outlet.
• Smart charging: Compatible chargers can manage when your vehicle charges.
• Solar integration: Use your solar generation to help charge your EV.
• Future ready: Choose a system that can work with your home’s changing energy needs.
• Professional installation: Our qualified electricians handle the electrical work from start to finish.

Can I charge my EV using solar power?

Yes. If you have enough power generation from your solar panels, an EV charger can make excellent use of your home’s renewable energy.

Rather than sending surplus solar electricity to the grid, a compatible charging system can direct some of that energy into your EV. Depending on the equipment and your energy requirements, smart charging can also help manage when your vehicle charges.

Already have solar? Tell us about your existing system when you enquire, and we’ll look at how your EV charging can work alongside it.

Which EV charger is right for my home?

There is no single EV charger that suits every home. Your ideal solution depends on your vehicle, electrical supply, charging requirements and whether you have solar or a battery.

StarDelta can assess your home’s electrical setup and recommend a practical solution rather than simply selling you a particular charger.

We can consider:

• Your EV’s charging capability
• Single-phase or three-phase power
• Your switchboard and available electrical capacity
• Solar and battery integration
• Charger location and cable requirements
• Smart charging and energy management

What types of EV chargers does StarDelta install?

From everyday home charging to high-powered DC fast charging, StarDelta can help you find the right solution. We install AC EV chargers for convenient home charging, including the Sigenergy 7kW AC charger, as well as EV charging solutions from Wallbox and Tesla. Depending on your vehicle and electrical supply, we can recommend a charger that suits how you actually use your EV.

For higher-power applications, we also offer DC fast chargers, including the Sigenergy 25kW DC Fast Charger. DC charging can provide much faster charging than a typical AC home charger, making it particularly useful for businesses, larger properties, fleets and drivers who need to get more energy into their vehicle in less time.

Can an EV charger send power back to my home?

Some modern EV charging systems can do much more than simply charge your vehicle. Bi-directional and V2X (Vehicle-to-Everything) charging can allow compatible electric vehicles to send stored energy back out of the vehicle.

Depending on the vehicle, charger and system configuration, this can open up exciting possibilities such as vehicle-to-home (V2H) and vehicle-to-grid (V2G) applications. Your EV could potentially become another part of your home’s energy system, working alongside solar, batteries and other electrical loads.

Bi-directional charging is an evolving area, and compatibility between the vehicle, charger and electrical system is essential. StarDelta can help you understand what’s currently possible and select equipment with future energy needs in mind.
