Power Generation Basics

Inverter Generator Vs Generator: Generation Basics

Power generation is the process of converting mechanical energy into electrical energy. Generators play a crucial role in power generation by providing a reliable source of electricity in various settings.

Whether you’re camping in the great outdoors or facing a power outage at home, understanding the basics of how generators work and the different types available can help you make an informed decision.

How do generators work?

Generators utilize the principle of electromagnetic induction to produce electricity. They consist of two main components: a prime mover and an alternator.
