You've bought an EV, or plan to, and want to know how to install a home charger and what it costs. With a home charger, the car charges while you sleep, so charging stops being a daily chore.
This guide covers the site assessment, electrical work, testing and handover. It also explains what affects the quote for a home EV charger installation in Saudi Arabia.
Step one: check your electrical panel capacity
Before you pick a charger or a spot for it, find out whether your panel can handle the extra load. An overloaded panel causes repeated power cuts and can start a fire.
What do you need to know?
- Electrical service size: Check your electricity bill or ask the electricity company for your service size. Residential services in Saudi Arabia are typically 40 to 200 amps.
- Current load: How much electricity does your home use now? Air conditioners are the biggest consumers in Saudi homes, especially in summer.
- Available capacity: The difference between your service size and your actual peak load decides whether you can add a charger without upgrading your service.
Your service rating alone doesn't show whether a charger is safe to add. A qualified installer first checks peak household demand, the supply and available phases, the electrical board and the proposed charging load. Then they recommend a charger and set its maximum current for the site.
If the assessment finds too little spare capacity, discuss the options with your installer and electricity provider. A supply upgrade or compatible load management may help. Confirm which option fits your home and agree the work and price before it starts.
Step two: choose the charger, 7 kW or 11 kW
Most Saudi homes choose between a 7 kW single-phase charger and an 11 kW three-phase charger. How do you choose?
7 kW charger, single phase, 32 amps
- Charges a 60 kWh battery from 20% to 100% in about 7 hours
- Ideal if you charge overnight. Plug in at 10 PM and the battery is full by morning
- Easier to install because it only needs a single phase
- Cheaper to purchase and install
- Sufficient for most users who drive less than 150 km per day
11 kW charger, three phases, 16 amps per phase
- Charges the same battery in about 4 hours and 30 minutes
- Suitable if you need faster charging or drive long distances daily
- Needs three phases in your electrical panel
- Slightly more expensive to purchase and install
- Your car must support 11 kW charging to use its full speed
For most users in Saudi Arabia we recommend a 7 kW charger. It's enough for overnight charging and costs less to buy and install. You can upgrade later if your needs change.
Step three: request a site survey from a specialist
Once you know roughly which charger you need, ask a specialist installation company for a site survey. Don't rely on your own estimate or a general electrician's advice. EV charger installation is a specialist job.
During the survey, the technician will:
- Inspect the main electrical distribution board and determine the available capacity
- Measure the distance between the panel and the proposed charger location to determine cable length
- Assess the cable route: indoors or outdoors, through walls or floors
- Verify the type of grounding and its compliance with standards
- Determine whether an upgrade to the service or the panel is needed
- Provide an accurate quote based on the actual site survey
Use the quote request form on climch.com to arrange a site assessment with Climatech Charger. Before booking, confirm that a survey is available in your area and ask about any fees.
Step four: electrical work and preparation
After you accept the quote, the electrical work begins. This is the most important part of the installation and includes:
Installing a dedicated circuit breaker
Your installer provides a dedicated circuit for the charger. They match the breaker to the charger, its configured current, the cable rating and site conditions, following the manufacturer's instructions and local requirements. The charger's power rating alone is not enough to choose a breaker.
Running the electrical cable
Your installer sizes the cable for the charging current you will use, allowing for the route, installation method, length, temperature and permitted voltage drop. They also check that the circuit protection suits the cable.
Installing an RCD for residual current protection
A qualified installer chooses residual current protection for your charger model and installation. Type A and Type B are not interchangeable. The installer checks the charger's built-in protection, follows the manufacturer's instructions and local requirements, and adds DC leakage protection where required. Have them test the protection before handover.
Grounding
Have a qualified installer check the earthing system and protective conductors, fix what needs fixing and test the finished installation. The right solution depends on your site, the charger's instructions and local requirements. Any change, including an extra earth rod, should follow that assessment.
Step five: install and test the charger
Once the electrical work is done, the technician installs the charger:
- Mounting the charger bracket on the wall: The technician fixes it with anchors suited to the wall, whether concrete, block or gypsum. Mount it 100 to 130 centimeters off the ground for easy access.
- Connecting the cables: The technician connects the cable from the panel to the charger's internal terminals, following the manufacturer's instructions.
- Insulation and connection testing: The technician measures the insulation of the cables and connections to confirm there is no leakage.
- Trial run: The technician connects the charger to the car and runs a real charge to confirm that charging starts and stops, the meter reads correctly, and the charger and car communicate.
- Testing protection systems: The technician tests the circuit breaker and RCD to confirm they trip correctly.
Step six: connect to WiFi and set up the app
Most modern home chargers connect to WiFi and run from a phone app. After installation, the technician will:
- Connect the charger to the home WiFi network
- Create your account in the charger's app and pair it with the device
- Configure your charging settings: schedule charging for off-peak tariff hours where available, set a maximum charge such as 80% to protect the battery, and turn on notifications
- Walk through the app interface and how to monitor consumption and costs
With scheduling, you plug in as soon as you get home, and charging starts at the time you set, for example midnight when grid load drops.
What affects your home charger installation quote?
The quote depends on the charger you choose and the work your home needs. Cable routing, the condition of the wiring, any upgrades and testing all affect the cost. Ask for a written quote that lists the included work and any exclusions.
A board close to the charger may mean less cable work. The final cost still depends on the site assessment and specified equipment. Get a written price for your installation before you decide.
Villas and apartments
Installing a charger in a villa
Villas are the easiest case. You own the panel, the garage is attached to the house, and you need no one's approval. In a large villa, a long run from the panel to the garage may add a little to cable costs.
Installing a charger in an apartment building
Installing a charger in an apartment is harder for several reasons:
- Building management or homeowners' association approval: Get written approval before any installation work starts.
- Long distance: The electrical panel may be on a different floor from the parking spot, meaning longer cable runs and higher costs.
- Electrical meter: The charger must be connected to your apartment's own meter so that your consumption isn't billed to the building's shared account.
- Tamper protection: If the charger is in a shared parking area, you may need a lock or an RFID card to prevent unauthorized use.
- Existing infrastructure: Some older buildings may have electrical panels that can't handle additional loads.
Tip for apartment residents: If you plan to buy a new apartment, look for projects with EV charging already built in. Many new residential projects in Saudi Arabia now include it.
Common mistakes to avoid when installing a home charger
- Using a regular outlet instead of a dedicated charger: Some people think a regular 13-amp household outlet is enough. It is dangerous. A regular outlet isn't designed for many hours of continuous draw and can overheat and start a fire. Always use a dedicated charger, known as EVSE, with full protection.
- Hiring a non-specialized electrician: A general electrician may run wires well but may not know the protection, breaker type and grounding an EV charger needs.
- Ignoring grounding: Proper grounding is a safety requirement. Without it, many chargers won't start charging at all, because the protection system detects the missing ground.
- Choosing a cable with insufficient cross-section: A thin cable causes voltage drop and overheating. The technician must calculate the cable cross-section from the current and distance.
- Installing the charger in direct sunlight: In Saudi Arabia's heat, direct sun all day shortens the charger's life and affects its performance. Choose a shaded spot or put it under the garage roof.
- Don't skip residual current protection. Ask a qualified installer to check the full protection system, including how the charger's built-in protection works with upstream devices. Have them test it before handover.
How long does a home charger installation take?
A typical timeline with a professional installer such as Climatech Charger:
- Days 1 to 2: Initial contact and needs assessment
- Days 3 to 5: Site survey and quote submission
- Days 6 to 8: Quote approval and charger order
- Days 9 to 14: Sourcing the charger and materials, depending on stock
- Days 15 to 16: Installation, testing, and handover
If the charger is in stock and the wiring is simple, the whole project can take one week. The on-site work usually takes 3 to 6 hours.
Maintenance tips after installation
A home charger needs simple routine maintenance to stay safe and work well:
- Regular cleaning: Wipe dust and dirt off the charger with a dry cloth at least once a month. Heavy dust in Saudi Arabia can block the ventilation openings.
- Cable and connector inspection: Visually check the charging cable for any cracks or sharp bends. Clean the connector terminals of any dirt.
- Test the breaker and RCD. Use the test button at the intervals stated in the device manufacturer's instructions. Have a qualified installer perform the electrical checks and maintenance tests that need specialist equipment.
- Firmware updates: If your charger connects to the internet, turn on automatic updates.
- Annual inspection: Have a professional inspect the charger once a year. The check covers insulation, connections and the protection system.
With proper care, a good home charger lasts 10 to 15 years and saves you a lot compared with fuel or public charging.
