A generator, also known as a power generator, is a device that converts mechanical energy into electrical energy. It is primarily used to provide backup power during outages or to supply electricity in locations without access to the power grid. Generators are essential in situations where continuous power supply is critical.

An inverter generator produces electricity with a pure sine wave output, ensuring more stable and cleaner power. This is especially important for sensitive electronics such as computers, medical devices, and communication equipment, as it reduces the risk of damage caused by power surges or fluctuations.

An ATS (Automatic Transfer Switch) box is an automatic switching system that connects a generator to the main electrical grid. It monitors the power supply and automatically starts the generator if the grid power fails, ensuring continuous power. When power is restored, the ATS shuts down the generator and reconnects to the main grid. This system is particularly useful for preventing downtime in critical applications.
