• Read the user manual and follow the instructions strictly.

Care & Maintenance Tips

If you follow Powertoolsgudie’s maintenance guide, you’ll get hours of hassle-free service from it. It’s recommended that you run your generator with at least 50 percent of load capacity. That means, with a 5000-watt generator, the load should be minimum 2500 watts.

Most generators come with an hour-meter. Note the run hour each time after changing oil level and also inspect the air-filter. Be aware of the specific hours when you’ll require to service your generator.

After every 9 or 10 hours, make a visual inspection. You should change the fuel filters every 500 years. For conventional generators, adjust the valves every 800-900 hours. Don’t forget to check the slip rings, brushes, and exhaust system.

Finally, check your rubber fuel supply-lines every year for any damage or cracks. According to your manufacturer’s suggested interval time, change the filter, air cleaner, and engine oil.

FAQs

1. Are propane generators more efficient?

Ans: Propane generators produce less BTUs compared to diesel or gas powered generators. So they are less efficient than their alternatives. But propane is a much cleaner burning fuel than diesel or gasoline, which makes it better for the environment as well as your generator.

2. Why is propane used as a fuel?

Ans: Propane has a higher energy content and burns with oxygen at 1980°C. It burns cleaner than other fuels, leaving behind carbon-dioxide, heat, and water. The heat helps power the internal combustion-engine to produce electricity. Propane also increases runtime of your generator.

3. What size generator do you need?

Ans: With a propane generator rated from 5000 to 7500 watts, you can use most of your household equipment, such as a refrigerator, freezer, well pump, and lightings. However, a 3000 to 4000 watt generator will be enough for RV.

4. How does a propane engine produce electricity?

Ans: A propane generator uses either liquid or vapor fuel-injection system. In both these systems, propane remains in a liquid state in the tank. In the vapor system, propane goes from a hose into its engine. Then with a regulator, it’s converted into vapor. On the other hand, in a liquid injection system, liquid vaporizes only after reaching the injector. When the engine is at 3600RPM, electricity starts to produce.

5. How loud are propane generators?

Ans: Propane or any other fuels don’t affect the level of noise. The noise depends on the inverter units. Conventional generators are usually louder than inverter ones. So, if you want a quiet environment, choose an inverter propane generator.

6. How many hours will a generator run on propane?

Ans: Most of the propane tanks come with a capacity of 500 to 1000 gallons. A propane generator can burn 2 to 3 gallons per hour. You can expect a 500 gallon tank to power your house for about a week and a 1000 gallon tank may last for two weeks.

7. Is it cheaper to run a generator on propane or gas?

Ans: Diesel is the cheapest option for generators. Gas generators use less fuel than propane generators. However, propane doesn’t expire while gas may expire in a year.

8. How much propane does a 20kw generator use?

Ans: At full load, a 20kw generator uses around 3 gallons per hour. At 80% capacity, a 500 gallon tank can continuously produce power for a whole week.
