Common Mistakes When Choosing a Diesel Generator

Choosing a diesel generator is not just about finding the lowest price. The wrong choice can lead to insufficient power, higher fuel costs and unstable operation.

Here are five common mistakes buyers should avoid.

1. Choosing the Wrong Power

Don't select a generator only based on normal running load. Motors, pumps and compressors may require much higher starting power.

Always consider the total load, starting current and possible future expansion.

2. Confusing Prime and Standby Power

Standby power is mainly for backup use, while prime power is designed for longer and more frequent operation.

Make sure the generator rating matches how you plan to use it.

3. Ignoring Voltage and Frequency

Different markets require different electrical configurations.

Before ordering, confirm voltage, 50Hz or 60Hz, single phase or three phase to avoid compatibility problems.

4. Choosing the Wrong Generator Type

Open-frame and silent generators are designed for different environments.

For noise-sensitive locations, a silent generator can be a better choice. For construction sites and industrial applications, an open-frame unit may be more practical.

5. Focusing Only on Purchase Price

The cheapest generator is not always the most economical choice.

Consider fuel consumption, engine quality, alternator, controller, maintenance and spare parts availability as well as the initial price.
