Introduction
Power outages are a growing concern across South Africa, affecting homes, businesses, and essential services alike. With load-shedding becoming an almost daily occurrence, having a reliable generator isn’t just a luxury — it’s a necessity. But purchasing a generator isn’t as simple as picking the first one you find online. The real challenge lies in selecting reputable generator suppliers in South Africa who can provide quality, service, and ongoing support.
This blog explores everything you need to know before choosing a generator and a trusted supplier. From understanding different generator types to evaluating supplier credibility and comparing features and prices, we’ll help you make an informed and confident decision. We’ll also highlight where to find dependable generators in South Africa, such as through Tasmaya, a reputable supplier offering a range of options for different needs and budgets.
Why South Africans Need Reliable Generators
South Africa’s power grid has been under increasing strain, with Eskom load-shedding frequently disrupting day-to-day life. Businesses suffer losses, medical facilities face operational challenges, and households are left without heating, cooking, or communication tools for hours on end.
According to a 2024 report by Stats SA, over 60% of small to medium businesses have invested in some form of backup power, and sales of generators have doubled in the past three years. As this trend continues, selecting the right generator—and more importantly, the right supplier—has become critical.

What to Look for in a Generator Supplier
Not all suppliers are created equal. Here are some critical factors to consider when choosing generator suppliers in South Africa:
1. Product Range and Availability
A good supplier should offer a variety of generator types, from portable to industrial. This gives you the flexibility to choose a unit that matches your needs precisely.
2. After-Sales Service
Generators require regular maintenance and sometimes repairs. Look for a supplier who offers:
- On-site installation
- Servicing plans
- Access to spare parts
- Troubleshooting support
3. Brand Partnerships
Reputable suppliers typically stock generators from well-known brands like Honda, Yamaha, Briggs & Stratton, or locally supported alternatives. These brands are tested for performance and safety in South African conditions.
4. Warranty and Certification
Check whether the supplier provides a warranty and whether the products meet SABS (South African Bureau of Standards) requirements.
5. Customer Reviews and Testimonials
Customer feedback is a strong indicator of a supplier’s reliability. A good reputation means consistent service, honest pricing, and responsive support.
6. Competitive Pricing
While cheap isn’t always best, the supplier should offer reasonable pricing and various options for different budgets. You can explore pricing at Tasmaya’s official website.

Understanding Generator Sizing: Avoid Over or Under-Powering
Choosing the wrong size generator is one of the most common (and costly) mistakes. A generator that’s too small won’t meet your energy demands, while an oversized one wastes fuel and increases maintenance costs.
Step-by-Step Sizing Guide:
- List all essential appliances (fridge, lights, routers, pumps).
- Check power ratings (usually in watts or kW).
- Calculate total power needed + 20% buffer for startup surges.
- Match with generator capacity (convert watts to kVA using: kW ÷ 0.8 = kVA).
💡 Example:
If your home requires 4,000W (4kW), you’ll need a generator around 5kVA (4kW ÷ 0.8 = 5kVA).

| Noise | Quieter in small units | Noisier in large models |
