The Ultimate Buying Guide for Your New Petrol Generator
A petrol generator is a powerful tool. It gives you electricity when the main power goes out. You can use it for camping, construction sites, or emergencies at home. Choosing the right one can feel tricky. This guide will help you pick the best petrol generator for your needs.
Key Features to Look For
When shopping for a generator, focus on these important parts first.
Power Output (Wattage)
- Starting Watts (Surge): This is the extra power the generator needs for a short time when you first turn on big appliances, like a refrigerator.
- Running Watts (Rated): This is the steady power the generator can provide continuously. Always buy a generator with more running watts than you need.
Run Time and Fuel Tank Size
A bigger fuel tank means the generator runs longer without needing a refill. Check the run time at 50% load. This tells you how long you can expect it to work between refueling stops.
Inverter vs. Conventional Generators
Inverter Generators: These make “cleaner” power. They are great for sensitive electronics like laptops and phones. They are usually quieter.
Conventional Generators: These are often cheaper and more powerful for running big tools, but the power quality is rougher.
Noise Level (Decibels – dB)
If you plan to use the generator near your home or neighbors, a lower decibel rating is better. Quiet models often cost more.
Important Materials and Build Quality
The quality of the materials directly affects how long your generator lasts.
Engine Quality
Look for well-known engine brands. Strong engines usually last longer. A good engine has features like low-oil shutoff. This feature stops the engine if the oil level gets too low, protecting it from damage.
Frame and Housing
The frame should be made of strong steel tubing. This protects the engine from bumps and scrapes, especially important on construction sites. Weather-resistant housing keeps rain and dust out.
Fuel Tank Material
Most modern tanks are made of durable plastic or coated metal. Metal tanks resist cracking better over many years.
Factors That Improve or Reduce Quality
Some features make using the generator much better. Others might signal a lower-quality product.
Quality Improving Factors
- Electric Start: A push-button start is much easier than pulling a cord, especially for older users.
- Voltage Regulation (AVR): Automatic Voltage Regulation keeps the power output steady. This protects your electronics.
- Portability: Wheels and handles make moving the heavy unit much easier.
Quality Reducing Factors
Be careful about generators advertised as “ultra-cheap.” These often use lower-grade wires and weaker components. They might break down sooner. Also, very light plastic casings usually mean the internal parts are not well protected.
User Experience and Use Cases
Think about where and how you will use the generator most often.
Home Backup Use
For emergency home backup, you need reliable starting power. Inverter models are good if you want to run sensitive items like your modem and TV. You need enough wattage to run your refrigerator and some lights.
Recreational Use (Camping/RVing)
For camping, portability and low noise are key. Inverter generators are the standard choice here because they are quiet and fuel-efficient.
Job Site Use
Construction sites need brute strength. You need higher running watts to power heavy tools like circular saws. Durability is more important than quiet operation.
Frequently Asked Questions (FAQ)
Q: What is the difference between AC and DC outlets?
A: AC (Alternating Current) outlets power standard household items like lamps and tools. DC (Direct Current) outlets are sometimes used for charging 12-volt batteries directly.
Q: How often should I change the oil in my petrol generator?
A: Most manufacturers suggest changing the oil after the first 20 hours of use. After that, change the oil every 50 to 100 hours of operation, or at least once a year, whichever comes first.
Q: Can I run a generator indoors?
A: Never run a petrol generator indoors or in a garage. They produce carbon monoxide, which is a deadly, odorless gas. Always place generators outside, far away from windows and doors.
Q: What kind of petrol should I use?
A: Most modern generators use regular unleaded petrol (often 87 octane). Always check your owner’s manual for the specific type recommended by the manufacturer.
Q: What is “load management”?
A: Load management means carefully turning on appliances one by one, starting with the biggest power-draw item first, to avoid overloading the generator.
Q: How do I store a generator for a long time?
A: You must drain the fuel tank completely or add a fuel stabilizer. Old petrol can clog the carburetor. Store the generator in a dry, covered area.
Q: Are inverter generators always quieter?
A: Yes, inverter generators usually run at a lower, variable speed when the load is small. This makes them significantly quieter than conventional generators running at a constant, loud speed.
Q: What does “parallel capability” mean?
A: Parallel capability means you can connect two smaller inverter generators together. This doubles your available power when you need it, while still allowing you to run just one small unit for quiet tasks.
Q: How much does a good, reliable generator cost?
A: Prices vary widely. Small, low-wattage inverter models might start around \$400. Larger, high-wattage conventional models for home backup can cost \$1,500 or more.
Q: Does a generator need to be grounded?
A: Yes, for safety, most portable generators must be properly grounded, especially when used at a campsite or job site, to prevent electric shock hazards.
