Installing an EV Charger in Johannesburg: Your Complete Guide
Johannesburg and Gauteng lead South Africa in EV adoption, driven by long commutes, high petrol costs, and progressive business districts embracing electric mobility. With City Power electricity rates (R1.95-R3.40/kWh) offering substantial savings over petrol, home charger installation delivers exceptional returns for Johannesburg drivers.
This comprehensive guide covers everything Gauteng residents need to know about EV charger installation, from costs and requirements to load shedding solutions and solar integration.

Why Home Charging is Critical for Johannesburg EV Owners
The Johannesburg Reality
While Johannesburg has excellent public charging infrastructure (GridCars operates 350+ stations nationwide with the highest concentration in Gauteng), 95% of EV charging happens at home. For Johannesburg’s long commutes and heavy traffic, home charging isn’t optional – it’s essential.
Johannesburg-Specific Challenges Home Charging Solves:
- Long commutes: Pretoria to Sandton (50km each way) daily
- Traffic congestion: N1, M1 stop-and-go driving
- Time constraints: No time for public charging stations
- Load shedding: Smart charging works around outages
- High petrol costs: R20,000-R40,000 annual fuel expenses
Cost Reality: The Johannesburg Advantage
For typical Johannesburg commute (Fourways to Sandton: 40km daily):
Petrol vehicle annual cost: R21,600 (12,000km ร R1.80/km)
EV home charging cost: R4,680-R7,344 (City Power rates)
Annual savings: R14,256-R16,920
Your charger installation (R15,000-R18,000) pays for itself in 11-15 months. Every month after that is pure savings.

Understanding EV Charger Types for Gauteng Homes
Recommended: 7kW AC Home Charger
For most Johannesburg residential properties, a 7kW charger is optimal:
| Specification | Details |
|---|---|
| Power Output | 7 kW (32A single-phase) |
| Charging Speed | ~30-35km range per hour |
| Full Charge Time | 8-9 hours (60kWh battery) |
| Daily Range Added | 200-300km (overnight) |
| Covers | Even Pretoria-Sandton daily commute with range to spare |
Why 7kW is Perfect for Johannesburg:
- Fully charges any EV overnight
- Works on standard single-phase power
- More affordable than 11kW+ options
- Handles even longest Gauteng commutes
- Optimal for typical 40-80km daily driving
Smart Chargers: Essential for Johannesburg
Basic Chargers (R6,000-R8,000):
- Plug and charge functionality
- LED status indicators
- Built-in safety features
- Weatherproof housing
Smart Chargers (R9,000-R12,000) – STRONGLY RECOMMENDED:
- โ Smartphone app control and monitoring
- โ Scheduled charging (avoid load shedding)
- โ Load shedding schedule integration
- โ Off-peak rate optimization
- โ Solar integration capabilities
- โ Energy usage tracking
- โ Load management (prevent overload)
- โ Remote diagnostics and updates
Why Smart Chargers are Critical in Johannesburg:
- Automatically schedule charging between load shedding windows
- Integrate with solar/battery systems (common in Gauteng)
- Charge during cheapest City Power rates
- Track exact savings vs petrol costs
- Adjust to available power during load shedding
The R3,000 premium for smart features pays for itself within 6-8 months through optimized charging and load shedding management.

โ ๏ธ Critical Insurance Requirement: Without a valid CoC, your home insurance may be void if electrical issues occur. Always demand your CoC at installation completion.
City Power and Municipal Regulations
Johannesburg Electrical Compliance:
- All work must comply with City Power regulations
- Installer must be registered with Department of Labour
- CoC must be issued by registered electrician
- Some areas require City notification for major electrical work
Complex/Estate Considerations (Common in Johannesburg):
- Body corporate approval required (get this FIRST)
- Aesthetic guidelines compliance

Monthly Fuel Savings: R1,188-R1,410 (typical 1,200km/month Gauteng commuter)
Payback Period: 11-16 months
After just over one year, you’re saving R14,000-R17,000 annually on fuel costs – every year for the life of your EV.
Load Shedding: The Johannesburg Challenge
Reality Check: Load Shedding Does NOT Prevent EV Charging
This is the #1 concern for Johannesburg EV buyers. Here’s the reality:
Why Load Shedding Rarely Affects EV Charging:
- โ EVs need 7-8 hours for full charge
- โ Even Stage 6 provides 12+ hours daily power
- โ Most charging happens 10pm-6am (minimal load shedding)
- โ Smart chargers automatically schedule between outages
- โ Typical EV: 400km range (8-10 days driving on one charge)
- โ Easy to find charging windows even with frequent load shedding
Smart Charging Strategies for Gauteng
1. Automated Load Shedding Scheduling
- Smart chargers integrate with load shedding schedules
- Automatically charge during power-available windows
- No manual intervention required
- Adapts to changing load shedding stages
2. Overnight Charging Window
- 10pm-6am: 8 hours of charging time
- Load shedding less frequent during these hours
- Sufficient to fully charge any EV
- Set charger to start automatically at 10pm
3. Solar + Battery Integration
- Charge during Gauteng’s sunny days
- Solar continues working during load shedding
- Battery storage provides charging during outages
- Complete energy independence possible
4. Workplace Charging Option
- Many Johannesburg offices installing EV chargers
- Sandton, Rosebank business districts leading adoption
- Charge during work day (no load shedding impact)
- Supplements home charging
Real Johannesburg Example
Scenario: Fourways resident, Stage 4 load shedding
- Daily load shedding: 8 hours total (in 2-hour blocks)
- Available power: 16 hours daily
- Required to charge EV: 8 hours (full charge)
- Charging window: 10pm-6am (8 hours, minimal load shedding)
- Result: Zero impact on charging routine
Solar Integration: Essential for Johannesburg
Why Solar + EV Makes Perfect Sense in Gauteng
Johannesburg receives excellent sunshine, and load shedding has driven massive solar adoption. Combining solar with EV charging creates exceptional synergy:
Solar + EV Benefits:
- Drive on free solar energy
- Near-zero fuel costs
- Complete load shedding independence
- Use excess solar production (vs feeding to grid)
- Property value increase
- Environmental impact: zero-emission driving
Solar System Sizing for Johannesburg EVs
| Solar System | Daily Production (Gauteng) | Daily EV Range | Best For |
|---|---|---|---|
| 5kW System | 18-22 kWh | 100-120 km | Household + covers typical daily commute |
| 8kW System | 29-35 kWh | 160-195 km | Household + long commutes (Pretoria-Sandton) |
| 10kW+ System | 36-45 kWh | 200-250 km | Large homes + complete EV charging + excess |
Coordinate Installations: If planning solar, coordinate with EV charger installation for optimal integration. Smart chargers can prioritize solar charging automatically.
Real Gauteng Example
Scenario: Sandton resident with 8kW solar + battery system
- Daily solar production: 32 kWh average
- Household consumption: 18 kWh daily
- Excess for EV: 14 kWh (78km range)
- Monthly EV “fuel” cost: R0
- Annual savings vs petrol: R21,600+
- Load shedding impact: None – fully independent
