Reliable power keeps operations running. For energy operations managers, selecting the right backup system can mean the difference between smooth performance and costly downtime. In this article, we explain the key differences between genset vs inverter systems, how each works, and how to choose the best option for your facility.
What Is a Genset?
Genset Meaning and Function
A genset, short for “generator set,” combines an internal combustion engine with an alternator. The engine produces mechanical energy by burning fuel. The alternator then converts that energy into electrical power.
How Genset Works
The engine burns fuel—commonly diesel, natural gas, or propane—to create rotational energy. The alternator uses that motion to generate electricity. Gensets supply alternating current (AC), which powers most industrial and commercial equipment.
Genset Applications
Operations managers often use gensets for:
- Industrial facilities
- Offshore platforms
- Marine vessels
- Hospitals
- Construction sites
- Data centers
At React Power Solutions, we carry new and used gensets from trusted brands like Caterpillar, Cummins, Kohler, Waukesha, and Detroit Diesel, ensuring your operation has a reliable power source.
What Is an Inverter?
Inverter Function and Technology
An inverter converts direct current (DC) into alternating current (AC). Instead of burning fuel directly, inverters draw DC power from batteries, solar panels, or hybrid sources. The internal electronics then create a stable, consistent AC output.
Inverter Applications
Inverters work well for:
- Backup power for offices
- Residential use
- Sensitive electronic equipment
- Portable or temporary setups
