Best 22KW Standby Generator

It is needless to dwell much on the importance of electricity. We are all aware of that. That’s why we all need a 24-hour power supply. Unfortunately, this is not possible in many parts of the world for several reasons. One major cause of power outages is a natural disaster.

Floods, hurricanes, thunderstorms, earthquakes, and other natural disasters usually cause power outages that could last for days. This is why many homes and organizations now have standby generators as a backup. In fact, power is not stable in many parts of the world, especially in African countries.

Many homes run generators for several hours every day. In recent years, the demand for standby generators has increased dramatically. That’s why its production has increased too.

This review is for 22KW generators. We tested many of them and came up with the five reviewed below. They are the best among them. We took the time to review each of them separately. At this juncture, we must remind you that we’re not affiliated with any of the brands.

Even in the office, it will power your computers, servers, printers, scanners, and copiers. This is why it is the best option for many homes and offices.

Will A 22KW Generator Run My House?

We can’t just answer the question directly. It depends on your power consumption. To answer the question, you need to list all the appliances that you want the generator to power.

Get the wattage or amperage of each of them. Add them up. If they are not up to 22KW, then a 22KW generator should be able to run your house.

On the other hand, if the total is more than 22KW, you’ll need to remove some appliances. Afterall, it is not likely that you’ll need all your electrical appliances at the same time. So, the answer to the question depends on your total power consumption.

How Much Does It Cost to Install A 22kW Generator?

  • Size – The bigger the generator, the higher the cost of installation.
  • Brand – Notable brands cost more to install than obscure or new brands of generators.
  • Distance – The distance between the generator spot and your home matters too. The longer the distance, the higher the installation cost.
  • Service provider – Some installation experts charge higher than others. So, you should compare quotes before making a choice.

What are The Prices of 22KW Standby Generators?

The generators come in different models and sizes. So, they differ in prices. One factor that determines the prices of generators is the brand. Tested and trusted brands like Generac will cost more than generators from new brands.

5. Test it Before its Return Window Closes

Make sure you get your generator installed quickly after delivery. When you discover anything you don’t like about it, you can return it. Conversely, if you wait until the return window closes, you won’t be able to return it.
