5 Key Things to Consider When Choosing and Buying a Generator

The generator you buy and choose for your business or job site requirements must provide you with the power you need. And since applications in job sites differ widely, generator selection must be taken on a case-by-case basis.

For instance, small commercial remodels will need a different generator when compared to road construction jobs or big bridge refurbishment. This is why it is vital to work closely with a reliable supplier to choose the right generator which suits your job requirements.

When talking to a supplier, there are several factors you will need to put across to ensure you choose the right generator. Some of these factors are:

  1. Power and Size

When looking for diesel generators for sale, you must choose one that can serve you well. You will have to look at how many appliances your diesel generator will power as well as for how long.

Another aspect you must look at is how regularly you will use the generator at a time. If you are using it as the backup when there is a power outage, then you have to make sure your generators can provide the load for a long period.

  1. Transfer Switch Type

A transfer switch for an emergency standby system is normally an automatically controlled type. A manual transfer switch may be supplied for some systems if you want to. But lack of automation doesn’t come with cost savings.

The size of a transfer switch as well as the installation location, needs to be determined by an electrician. If the transfer switch is sized and designed to manage the entire building, then the system will need to be rated. For industrial or commercial applications, you will need to ensure your switch transfer has the following features:

  • Programmed transition
  • Closed transition
  • Bypass isolation
  1. Costs

It is important to have a budget and stick to it. While you might want one of the ultra-powerful backup generators, it might not be within your budget.

But some companies have payment plans for individuals in the same situation. So contrast and compare pricing so as to know the best option for your unique situation.

  1. The Weight

The generator’s weight is something that you shouldn’t overlook. A heavy generator can be suitable if you are running a mobile business. 

That is because it will be extremely difficult for you to move around. But if your generators will always be stationary, then having ones that are heavy won’t be much of a problem.


  1. Safety Concerns

Before you choose or buy any generator, it will be best to know the safety concerns involved. Similar to everything, which produces exhaust, generators may also lead to carbon monoxide poisoning when you are not keen.

According to experts, it is advisable to avoid running a generator in an enclosed space. And if you could, invest in a portable carbon monoxide detector to ensure exhaust doesn’t find its way to the living quarters.

In a Nutshell!

Buying a generator is not as complicated as you think. But before investing money in a new generator, ensure you are well familiar with models and usages.
