What types of EV chargers are sold in South Africa?
You need an EV charger that works safely during load shedding and meets South African compliance. There are three practical categories for residential use. The first is a basic unit that plugs into an existing socket. It is cheap and easy, but it draws a modest amount of power and relies on the socket's rating. If you only top up a few kilometres a day, that may be enough.
The second option is a dedicated wall‑mounted charger that ties directly to a circuit breaker. This version delivers a higher charge rate and includes built‑in safety features such as earth‑leakage protection. It also matches the home's electrical capacity, which a qualified electrician will confirm. The installation cost is higher, but the speed and reliability are worth it for most drivers.
The third choice is a smart charger. It talks to the vehicle and can be programmed to charge only during off‑peak periods or when a backup inverter is active. Smart chargers add convenience and can protect the battery from unnecessary cycles. They also let you monitor usage from a phone.
For most homeowners, the dedicated wall‑mounted unit offers the best balance of speed and safety. It can be sized to the home's load and can integrate with a solar inverter if you already have a PV system. If budget is tight, the socket‑type charger remains an option, but expect slower charging.
Do I need a licensed electrician to install an EV charger?
The short answer is yes. South African regulations require that any new permanent wiring be performed by a registered person. The electrician will assess your distribution board, verify that the circuit can handle the charger's load and install a suitable residual‑current device. Only after the work is completed can the electrician issue an Electrical Certificate of Compliance (COC). The COC is mandatory when the property is sold or transferred.
Attempting a DIY install risks overheating, tripping the main breaker and voiding insurance. A professional site visit also reveals hidden issues such as undersized cables or the need for a separate earth rod. Those problems are not obvious until a qualified eye looks.
How does load shedding affect home EV charging?
Load shedding is scheduled by Eskom and, in parts of Johannesburg, by City Power. When the grid is offline, any charger that relies solely on grid power will stop. If you have a hybrid inverter paired with a LiFePO4 battery, the charger can continue to draw from stored energy, allowing you to top up the vehicle even during an outage.
Choosing a charger that can be set to operate only when the inverter is active prevents unnecessary strain on the battery. It also shields the vehicle's battery from deep‑discharge cycles that could shorten its life. In practice, you will see the charger pause and resume automatically as power returns.
What is the process for obtaining a Certificate of Compliance after installation?
After the electrician finishes the wiring, they will test the circuit for correct earthing, proper breaker sizing and continuity. The test results are recorded on a compliance form that the electrician signs. The form becomes the Certificate of Compliance. Keep this document with your other property records; it is required for any future sale or lease.
If you are adding the charger to an existing solar or backup system, the electrician will also verify that the new load does not exceed the inverter's rating. That step is essential to avoid overloading the system during peak demand. Ignoring it can lead to frequent trips and costly repairs.
How do I choose the right charger for my home and vehicle?
Start by confirming the make and model of your electric vehicle. Manufacturers specify a maximum charging rate, and a charger that exceeds that rate will not charge faster. Next, consider your home's electrical capacity. A registered electrician will measure the available load and recommend a circuit size that matches both the charger and any existing loads.
If you already have a solar installation, look for a charger that can integrate with your inverter's communication protocol. That integration lets the charger draw from solar production during daylight and switch to battery backup when the grid drops out. It reduces reliance on the mains.
For households that experience frequent load shedding, a charger with a programmable schedule is the safer choice. You can set it to charge only when the inverter is providing power, protecting both the vehicle and the home battery. Simpler chargers lack this feature, so weigh convenience against cost.
Finally, compare the warranty terms of the units you are considering. A longer warranty often reflects a more robust design, which aligns with the safety‑first approach required for high‑current installations.
Next steps, getting a safe, compliant installation
Contact a registered residential electrician in Sandton or the surrounding Johannesburg suburbs. Request a site visit. The electrician will assess your distribution board, your existing solar or backup system and your vehicle's requirements. They will then provide a written quote and schedule the installation.
When the work is complete, the electrician will issue the Certificate of Compliance. Keep that certificate safe; it protects you legally and adds value to your property. A proper install also means you can charge confidently, even when load shedding strikes.
Installing an EV charger is a practical step toward reliable, low‑emission transport. With a qualified professional, the job is safe, legal and future‑proof.
Common questions
Do I need a licensed electrician to install an EV charger?
Yes. South African law requires a registered person to perform the wiring and to issue a Certificate of Compliance.
Can I use a regular household socket for EV charging?
It is possible for very low‑power charging, but a dedicated charger provides safety, reliability and meets legal standards.
How does load shedding affect home charging?
When the grid is off, a charger will stop unless you have a backup inverter or battery system that can supply power.
What paperwork is required after installation?
The electrician must provide a valid Electrical Certificate of Compliance, especially if the property is sold or transferred.
