Buying Guides

Some factors to look out for when selecting the best standby generator

1. Capacity of generator

The first thing we need to notice when buying a generator is to consider electricity consumption. It means that you can count the number of devices that will be used during a power outage as well as the total power consumption. 

Therefore, you can choose the device with the right capacity. This helps to avoid overloading, short-circuiting, and burning of items connected to the generator.

According to experts, products with a capacity higher than the actual consumption capacity from 10% to 25% are a perfect choice. For example:

  • If your family only needs a generator to light, use a fan and turn on the TV, it only needs a small type from 2 to 4 kW.

  • If you want to use more power-hungry equipment such as air conditioners or warmers, you should choose a type with a large capacity of 4 to 6 kW.

  • If your house has more electric devices, you should choose one with bigger capacity. 

Do not choose a generator for the family with too high a capacity because it will lead to high cost, fuel consumption and easy shortening of life.

2. Price

There are many factors that influence the final cost of a backup generator. This makes it difficult to determine the exact price. However, a good general rule of thumb is that the final installation cost is usually twice the price of the generator.

3. Operating system

Note that there are two basic engine operating systems for generators. They are:

  • Air-cooled generator

  • Liquid-cooled generator

Air-cooled generators are smaller and less expensive. However, their downside is that they are noisier than liquid-cooled models. Meanwhile, liquid-cooled generators are usually larger.


FAQs

Frequently Asked Questions

1. Should I use the full capacity the machine provides?

The total power consumption should not exceed the generator power. Ideally, you should use about 80% of the design capacity so as not to overload the motor.

2. Should a voltage stabilizer be used for power?

Do not use voltage stabilizers to energize because if you use two devices with the same large frequency, it will be easy to cause conflicts and short circuits.

3. Where should my standby generator be placed?

  • You should install the generator in a safe location

  • Do not place in locations with high humidity

  • Avoid placing in front of the store

  • Avoid placing at the top of the wind direction, which is toxic to users

  • It is better to the standby generator in a flat and dry area

4. How to properly start or shut down the standby generator?

This is a very important point to note for those who are new to generators. 

You should start the generator properly by running the machine idling for about 5 to 10 minutes. After that, let's plug in electrical equipment. 

Turning off the power should also follow the correct procedure. You should unplug all electrical equipment and then disconnect the power.

5. Are there any rules for using standby generators?

Sure. A lot. 

You can refer to some of the following notes we recommend to ensure the generator is efficient when in use. They actually also help you operate safely as well as protect equipment and prolong its life.

  • When refueling, you need to make sure that the generator is in the off mode. Otherwise, this may cause an explosion

  • Use only the fuels specified for the machine, absolutely do not use other fuels

  • If you do not often use standby generators, you should start it once a week

  • Do not use the device continuously for a long time, use about 3 hours, you should turn it off and restart

  • Do not connect the generator to the main electrical panel in the house or turn the generator into a transformer. This is extremely dangerous and easily causes a repeated electric shock. You should use electricity directly with electrical equipment that needs to be operated

  • Regularly check and clean the oil and water cooling system, the tension of the fan belt to prolong the life of the machine.


Final Words

No matter what size or type of standby generator you choose, we believe it's a significant investment. It is well worth the investment many homeowners are willing to make. This keeps their home and family safe and comfortable during an annoying power outage.
