Home vs Commercial Generators

By May 19, 2021 May 25th, 2021 No Comments

Some basic information to help you decide what power source you need;

Here at Critical Power we deal with commercial and industrial projects involving Generators from 50 kW and larger. We often get people coming to us for Generators to power their home. This is to help those first-time buyers.

First, lets talk size.

“You can run the most critical household equipment with a generator rated at 5,000 to 7,500 watts. These include things like a well pump, refrigerator and freezer, and lighting circuits.”*

So installing a unit between 5 kW and 10 kW would be ideal!****

Installing an oversize generator can cause issues and poor efficiency. Installing an undersized unit can damage the unit or fall short altogether.

Next let us talk about the fuel source.

What is currently available?

Do you have a NG source?

Can a Propane tank be installed?

Is Diesel necessary?

While diesel is the most widely used for emergency situations, Natural Gas is the most popular for permanently installed units. NG is cleaner to burn and often has a constant flow through a pipeline. Also, Propane tanks can be installed onsite as a great alternative to the others.

Now we need to talk about placement.

For emergency, portable generators,

“Always place the generator at least 20 feet from the house with the engine exhaust directed away from windows and doors.”**

For permanently installed generators,

  • In most cases, generator distance from property lines should be at least 5 feet;
  • Your unit should be at least 18 inches from your home; and
  • Keep at least 5 feet between your generator and any doors and windows to prevent fumes from entering your rooms. ***

And now, your generator needs an enclosure:

Weatherproof enclosures are great for keeping out the elements but lack sound insulation.

Sound Attenuated Enclosures are the top choice for residential generators for the obvious, generators are loud! Keep out the elements while keeping you (and your neighbors’) sanity. Lol!

What about voltage, hertz ratings, current?

****CPP&S will always recommend you contact your local electrician to make that call. Homes come in all shapes and sizes and there is no substitution for an onsite evaluation from a professional, licensed electrician. This is not the place to cut corners.

Critical Power carries new and pre-owned Generators for commercial and industrial applications. Our selection starts at 50 kW (50,000 watts) and goes up to 2.5 MW. With few exceptions, when approached for a residential generator we will refer to a reputable dealer.

We hope this helps you along the path of securing a power plan for your home!
