In this article, we look at the top 10 generator companies in the world. But before we jump into them, what are generators?

Generators are important pieces of machinery that convert mechanical energy into electrical energy. They are also at the heart of the utility power grid that distributes electricity to homes, businesses, and commercial facilities. Besides forming part of the power grid, generators are also used to provide power backup and redundancy, especially in the event of a power outage of the utility power.

Standby generator systems and portable generators have therefore become popular not only for hospitals where power outages can be life-threatening but also with businesses and homeowners as a way of maintaining essential systems and appliances when storms or other conditions cause a loss of power from the grid.

However, there are different types of generators. Their selection is based on factors such as the fuel source being used and the desired output voltage and power level. The selection may also be influenced by the brand/manufacturer. That said, these are the top generator companies/brands that should come to mind when you think about buying or renting a generator.
