A Practical Guide to Buying Used Generators in South Africa
Load shedding, rising fuel costs, and remote living have made generators a must-have in many South African homes, farms, and businesses. But with new units often priced out of reach, many people turn to the used market.
If you’re wondering whether to buy a used generator in South Africa, this guide will help you weigh the pros and cons, avoid costly mistakes, and make a smart purchase — whether you’re powering a small farm workshop, an off-grid home, or a local business.
Why Consider a Second-Hand Generator?
Generators are built to last, especially diesel-powered units. Many pre-owned models still have thousands of service hours left, offering great value — if chosen wisely.
Common reasons South Africans look for second-hand generators include:
- Avoiding the high cost of new models
- Temporary power backup needs
- Expanding power capacity for farms or businesses
- Off-grid or rural power redundancy
🔧 PROS of Buying a Used Generator in South Africa
✅ 1. Significant Cost Savings
Used generators are often priced 30–70% cheaper than their new counterparts. This is a major advantage, especially for small farms, homesteaders, and start-up businesses.
Example: A new 15kVA diesel generator may cost R70,000, while a reliable used one could go for R30,000–R40,000.
You get solid power at a fraction of the cost — ideal if you’re budget-conscious or need a temporary solution.
✅ 2. Faster Availability
New generators often have long lead times due to import delays or high demand during peak load-shedding. With a second-hand generator, you can buy it today and start using it tomorrow — a crucial advantage when you’re facing outages.
✅ 3. More Power for Less
With the same budget you’d use to buy a small new generator, you can often afford a larger used model — giving you:
- More appliances supported
- Longer runtime
- Better performance for farm equipment or welding
✅ 4. Tested in Real Conditions
Used generators that have been running successfully on a farm, construction site, or business offer proven reliability. New models may have undiscovered issues or need break-in periods. A properly maintained used generator has already shown its worth.
✅ 5. Ideal for DIY Repairs or Backup Units
If you’re technically skilled (or have a trusted local electrician), a used generator is a great project. Many farm mechanics prefer used models for:
- Easier repairs
- Readily available spares
- No electronic lockouts or complex software
⚠️ CONS of Buying a Used Generator in South Africa
❌ 1. Hidden Mechanical Issues
Used generators come with wear and tear. Without proper testing, you could inherit:
- Low compression
- Alternator faults
- Fuel system leaks
- Weak batteries or faulty AVR (Automatic Voltage Regulator)
Unless you inspect thoroughly or buy from a trusted seller, repairs could quickly eat into your budget.
❌ 2. No Warranty or Support
Most second-hand generators are sold as-is, meaning:
- No factory warranty
- No after-sales support
- Limited or no refund options
This makes it riskier than buying new — especially if you’re not confident inspecting engines and electronics.
❌ 3. Outdated Technology
Older models may lack:
- Auto start/stop
- Load-sensing features
- Remote monitoring or solar integration
- Fuel efficiency found in newer models
If you plan to run it often or integrate with a hybrid solar system, this could be a deal-breaker.
❌ 4. Lack of Maintenance History
Many sellers won’t have full service logs or proof of oil/filter changes. Without this, it’s hard to judge how the generator was treated:
- Was it overloaded?
- Left outside in rain?
- Run without regular oil changes?
A lack of service history means higher risk, especially for petrol or small inverter generators.
❌ 5. Fuel Consumption May Be Higher
Older diesel generators are often less fuel-efficient. While durable, they may cost more to run over time — especially compared to new inverter models with smart throttle control.
⚖️ Used Generator Buyer’s Checklist
Before you buy a used generator in South Africa, inspect the following:
- Running Condition
- Start and stop the unit
- Listen for unusual noises or smoke
- Test under load (plug in tools or appliances)
- Hour Meter
- Generators under 2,000–3,000 hours are ideal
- Over 5,000 hours: check compression and alternator closely
- Voltage & Frequency
- Use a multimeter to check steady voltage (220V or 380V as needed)
- Ensure 50Hz frequency stability under load
- Oil & Filters
- Look for clean oil and replaced filters
- Dirty filters = poor maintenance
- Cooling & Exhaust System
- Check for coolant leaks or overheating
- Look for carbon buildup around exhaust
- Spare Parts Availability
- Prefer well-known brands (Perkins, Cummins, Honda, Kipor, etc.)
- Avoid obscure imports without local support
- Documentation
- Ask for purchase proof, service history, and specs
- Avoid stolen or grey-market equipment

Final Word: Is a Second-Hand Generator Right for You?
Buying a used generator in South Africa can be a great investment — or a costly mistake. It depends on your power needs, technical skill, and how carefully you inspect the unit.
✅ A second-hand generator is a smart choice if:
- You want to save 40–60% over buying new
- You’re running it occasionally (e.g., during load-shedding)
- You can inspect or test it before purchase
- You prefer diesel or mechanical units with fewer electronics
❌ But it may not be worth it if:
- You rely on constant uptime
- You can’t test the generator in person
- You need a silent, ultra-efficient unit with solar compatibility
