What is the best generator for home loadshedding backup in South Africa?

For most South African homes the Gentech 3500W Pure Sine Wave Inverter Generator (R9,990) is the best all-round choice — safe for all electronics, whisper quiet at 56dB and fuel efficient. For budget backup the POWERBOSS 3kVA (R3,990) offers the best value. For larger homes needing more power the Gentech 7kVA or 9kVA are excellent options.

What is the difference between a conventional generator and an inverter generator?

A conventional generator produces power at a fixed speed — reliable and affordable but louder and not safe for sensitive electronics like laptops or solar inverters. An inverter generator produces clean pure sine wave power identical to mains electricity — safe for all electronics, quieter and more fuel efficient. Choose inverter for sensitive devices. Choose conventional for tools and basic appliances.

How much does a generator cost in South Africa?

What size generator do I need for my home?

For basic essentials (lights, TV, WiFi, fridge, phone chargers) a 3kVA generator is sufficient. For more appliances including a microwave, washing machine or multiple TVs, choose a 4.5–7kVA model. For powering an entire larger home including pool pump and multiple appliances, a 9kVA is recommended. WhatsApp our team for personalised advice!

Can I use a generator with my solar inverter or UPS?

Yes — but only with a pure sine wave inverter generator. The Gentech 3500W Inverter and TP5000 4S both produce pure sine wave power compatible with solar inverters, hybrid inverters and UPS systems. Conventional generators produce modified wave power that can damage inverter equipment.

How do I maintain my petrol generator in South Africa?

Run your generator at least once a month to keep the engine lubricated and fuel fresh. Always use fresh unleaded petrol. Check and change the oil every 50 hours of use or annually. Clean the air filter regularly. Store with an empty fuel tank if not using for extended periods. Follow the manufacturer's service schedule in your user manual.
