Petrol Generator FAQ: Backup for Rural Homes & Emergencies

In emergencies, having a reliable petrol generator can be the difference between being prepared or left in the dark.

By following the guidelines below and maintaining your generator properly, you’ll ensure you have a safe and dependable source of power whenever you need it.

How does a petrol generator supply power to my home?

• Fuel & Engine: You fill the generator with petrol and start it, causing the engine to run.
• Alternator: The engine drives an alternator that produces electricity.
• Power Output: You plug your appliances directly into the generator’s outlets or, for whole-home power, use a professionally installed transfer switch to safely connect to your home’s electrical system.
  

What size generator do I need?

• Determine Wattage: Make a list of devices and their wattage requirements—especially critical items you want powered in an emergency (like refrigerators, freezers, medical devices, lights).
  
• Add Up: Sum these wattages. Your generator should comfortably handle the combined load.
  
• Include a Safety Margin: Choose a generator with a bit more capacity than you think you need to handle sudden power spikes when devices turn on.
  

Where should I place my generator?

• Outdoors Only: Generators emit dangerous carbon monoxide. Always run it outside in a well-ventilated area—never indoors or near open windows/doors.
  
• Stable Surface: Place it on flat ground to avoid tipping or rolling.
  
• Safe Distance: Keep it away from windows, doors, or vents to prevent exhaust from entering your home.
  

How do I start and stop the generator?

1: Starting:

• Check fuel level and oil level.
  
• Turn off or unplug appliances before starting.
  
• Follow the generator’s start procedure (often involves a choke/start pull or push button).
  

2: Stopping:

• Turn off or unplug connected devices.
  
• Switch off the generator.
  
• Let it cool before refuelling or storing.
  

Using a Surge Protector

• Why Surge Protectors Matter: Generators can sometimes produce power spikes or voltage fluctuations when they start, stop, or switch loads. Sensitive electronics (like computers, TVs, and gaming consoles) can be damaged by these sudden spikes.

What regular maintenance is required?

• Oil Changes: Check and change oil as recommended (often after a set number of hours).
  
• Air Filter: Clean or replace to keep airflow optimal.
  Spark Plug: Inspect and replace if worn.
  
• General Inspection: Keep the generator clean; tighten any loose parts and look out for damage.
  

Is it safe to use my generator in wet weather?

Generators must be kept dry. If operating in rain or snow, use a cover specifically designed for generators—one that shields from moisture but allows proper airflow.

Never operate in flooded areas or where water can reach the unit.

What important safety tips should I know?

• Carbon Monoxide Danger: Only run the generator outdoors, away from enclosed spaces or open windows/doors.
  
• Fire Risk: Turn off and cool down before refuelling. Keep the area clear of flammable items.
  
• Electric Shock: Keep it dry; don’t use damaged cords.
  
• Professional Assistance: If unsure about maintenance or wiring, consult a certified electrician.

A well-chosen and properly maintained generator offers essential backup power—particularly for rural homes—and can be a literal lifesaver by ensuring continued operation of crucial appliances, medical equipment, and home systems when the main power grid fails.
