Buying Guide

When purchasing diesel generators, the majority of consumers need clarification and guidance on what to look for. The power factor of the diesel generator, the total load of electricity, the electrical appliance's beginning current, the diesel generator's continuous operating duration, the continuous operation time, and the anticipated increase in electrical equipment.

Under typical conditions, the diesel generator's actual output power is 0.8 times its stated power. When choosing diesel generators, users must take this element into full consideration. 

There are two types of diesel generators: backup power and main power. The formula relates them: standby power/1.1 Equals main power. The diesel generator's primary power source can constantly run for 12 hours, but the standby power source can only operate continuously for one hour.

When calculating the power of a diesel generator, it is important to take the starting technique of the electrical appliances into account in addition to the power of all the other electrical devices. When they first turn on, many electrical types of machinery produce a significant instantaneous beginning current (3 to 6 times the typical operating current). 

As a result, depending on the size of the real electrical equipment, it is vital to set aside adequate space for a fast start when choosing a diesel generator. This is especially crucial when choosing diesel generators. By the way, the general rule when using diesel generators to start electrical equipment is to start large electrical equipment first and progressively work your way down to smaller electrical equipment.

It is important to provide enough room when choosing the size of diesel generators so that certain electrical equipment may be added later. Many customers find that the power of their diesel generators is inadequate soon after acquiring them because they have added some electrical equipment. As a result, they must immediately purchase a diesel generator with somewhat greater capacity, incurring unneeded secondary costs.

7 tips to choose the right one:

1. The quantity and combined power of the electrical equipment typically determine the power size of the diesel generator set.

The power of a generator is not just the total power of all the electrical equipment; it also takes into account how the electrical appliances are started.

When determining the power of diesel generators, it is important to consider both the starting power of each electrical appliance and the general beginning modes of direct starting and step-down starting or soft starting.

2. At times, it might be difficult to tell a diesel engine's power clearly. As an illustration, consider an 8kW diesel generator. The 8kW diesel generator is 10KVA if the power unit is "KVA." IKVA=0.8kW is the conversion ratio between them.

3. Diesel generators' "rated power" and "reserve power" are not the same thing! Be sure to make distinctions with clarity!

4. Prevent using diesel generators of the "little horse cart" variety, which provide insufficient power and cannot be utilized regularly.

5. Diesel generator configurations vary, prices vary, and configurations should not be considered when comparing diesel generator prices.

6. Carefully inspect the outside when purchasing a diesel generator set to avoid purchasing subpar or even reconditioned equipment.

7. In some operational conditions, high-configuration diesel generators are required and cannot be substituted by standard die


FAQs

1. Why is the generator engine not starting or hard to run?

We are not sure below is all the problem. However, you can refer to some reasons:

  • The working valves are not in the on mode

  • Exhausted or almost empty fuel system

  • Fuel supplied to the combustion chamber is not up to standard

  • Clogged or folded fuel hose

  • The engine has damaged spark plugs or dirt clings to the spark plugs for a long time due to not being cleaned

2. What should I do when the generator is not working?

Based on the above reasons, you can refer to the following tips:

  • You need to turn on the valves to the working state

  • Check if the fuel is empty, if it runs out, let's add more fuel

  • It is necessary to use qualified fuels to prolong the life of the machine

  • Please check the spark plugs and clean the spark plugs before starting the engine

3. My generator still works but no electricity. Why?

Power outages can occur for many reasons. For example:

  • Broken wiring

  • Bad contact,

  • Capacitor explosion

  • Broken AVR

  • Other reasons

4. What to do when the machine makes “strange” noises when operating?

Loose machine parts or worn-out bearings can lead to this problem. You need to fasten the machine parts or replace the bearings.

5. What is the difference between surge watts v.s running watts?

You can understand in a simple way as follows:

For example, the manual shows 5,000 surge watts and 3,000 running watts, then:

  • The generator can operate continuously with a wattage of 3,000 watts

  • It also has power handling in excess of 5,000 watts, but the run time will be shorter.


Conclusion

To help you find the best diesel generators, Homechit has recommended reputable brands for you. All these brands have achieved certain achievements in the market. You can completely trust and consider choosing the best product!
