Why You Need a Backup Strategy

Generators fuel continuity – they keep lights on, fridges running, and security systems active. Inverters offer quieter, indoor-friendly power with battery support. Still, both come with hazards if not used correctly: fires, electrocution, or worse. Let’s get your setup right.

Generator Safety 2025: No Shortcuts Allowed

1. Always outdoors
Never use your generator indoors, in a garage, or under a canopy. Carbon monoxide is deadly and odorless – set it up at least five metres away from doors and windows.

2. Ventilation matters
Flat surfaces and fresh air limit fire and fume risks. Keep the exhaust clear, pointing away from your home.

3. Safe refuelling
Wait for the generator to cool before topping up. Store petrol or diesel in certified, locked containers safely distanced from your house.

4. Right tools, right gear
Use outdoor-rated extension cords and plug into a properly earthed distribution box with leakage protection to prevent shocks.

5. Know your limits
Don’t connect more than your generator can handle. Add up the wattage of essentials like fridges, lights, and routers – and stay under the limit.

6. Cover it with insurance
Insurance often excludes unlisted items. Check your policy to ensure generator theft or damage is covered.

7. Bonus safety
Install a carbon monoxide detector indoors. It’s a small expense for major peace of mind.

Inverter Best Practice: Quiet But Requires Care

1. Professional installation only
An electrician must handle the installation, especially if tying into your DB board or grid. Mistakes can cause faults or trip alarms.

2. Size it right
Overestimate your power needs by 25%. Underpowered inverters can cause blackouts or damage.

3. Battery backup matters
Your inverter should have battery capacity to last through outages. If it can’t hold through four hours, it won’t help. Regular testing is key.

4. Pure sine wave
Use pure sine wave inverters for sensitive electronics – computers, smart TVs, and routers. Cheaper alternatives risk hardware damage.

5. Automatic switching needs testing
If your unit switches back to the grid automatically, make sure it actually works. Many users find their system fails to reconnect once power returns.

What Joburgers Are Saying

Local Facebook groups like I Love Fourways and Joburg Power Updates are full of warnings: “We thought the garage was safe – we nearly didn’t wake up.” The consensus? Regulations are overdue. If you live in an estate or sectional title property, check your body corporate’s rules – some require silent units or ban usage at night.

Bottom Line

Generators and inverters can be life‑savvy in Joburg’s power-shedding world – but only if used correctly. Forget shortcuts. Stick to the rules, invest in proper gear, and test regularly. Your family, home, and tech deserve it.

Stay illuminated, stay safe, Joburg.
