5 Things to consider when purchasing a Diesel Generator

Many business owners use diesel generators to power electrical equipment or to keep everything running during a power cut. Most of the cases you may simply cannot afford to have a production loss due to an power outage.

It’s an important decision and many factors go into this purchase beyond the obvious questions of brand preference and price while buying generator

Here are the top 5 things that you need to look in to while buying a generator

1.Whats your power requirement?

Generator sizing can be answered with the following question: In the event of a power outage, should the generator run the entire building or just emergency loads? When sizing a generator for an entire building, factors like peak demands during summer months and the amperage of your electrical service are relevant details. When sizing for emergency loads only, the emergency circuits need to be determined

2.Brand and seller

It’s always a good idea to go with a trusted manufacturer who has a reputation for producing equipment that can stand the stress and test of time, and so you can find parts and service that’s readily available if necessary. Apart from deciding the manufacturer, you must also choose the wise seller, who will be doing the installation and will be addressing the issues faced any further.

3.Enclosure type

An enclosure should have low profile design and easy access to all major components. It must house Engine, generator set, muffler and controls in the enclosure. Manufacturers offer sound-attenuated enclosures for different levels of noise generated. Every customer has an option from a standard weather enclosure to a custom package to meet strict requirements.

4.Voltage requirement

A primary concern when deciding what type of generator is best for your environment should be making certain you get the right electrical configuration. An electrical configuration typically includes the phase, voltage, kW, and hertz that are best for your application. Check with your seller and electricians before deciding on the generator.


It’s a good idea to understand the warranty duration and coverage of your standby system, and ask for upgrade costs if you prefer an increased coverage.


Just like your vehicle, your generator needs to be properly maintained to help ensure the equipment will start and run as expected during your next power outage. Unlike your vehicle, generators tend to be neglected for extended periods between power outages. This can result in equipment failure during that critical time when you need it. Whether you are a do-it-yourselfer or if you prefer the added insurance of a maintenance program, keeping your equipment maintained properly is highly important to ensure reliable operation

There are obviously numerous factors and considerations to take into account when buying a generator, but hopefully this article has helped to at least shed some light on many of the critical components.
