What Is a Portable Whole House Generator and How Does It Work?

A portable whole house generator is a type of generator that provides electrical power to an entire home during power outages. These generators are typically gas or diesel-powered and are designed for mobility, allowing them to be moved to different locations as needed. They can supply enough electricity to run essential appliances, heating, and cooling systems, and other electrical devices during an outage.


Portable whole house generators work by converting mechanical energy from the engine into electrical energy through an alternator. When the power goes out, the generator can be manually started or automatically activated (if equipped with an automatic transfer switch).
