A standby generator, also known as a backup generator, is designed to automatically provide power to a facility in case of an outage. Standby generators are typically connected to the facility's electrical system and are automatically activated when the main power supply is lost. They are usually installed outside of the building and are powered by natural gas or propane.
The main benefit of using a standby generator is its automatic activation in the event of a power outage. This ensures that the facility has a continuous power supply, which can be critical for businesses or facilities that require power for safety or other reasons. Standby generators are also typically larger than portable generators and can provide more power, making them better suited for larger facilities.
However, standby generators also have some drawbacks. They require regular maintenance and inspections to ensure that they are working properly. These can be costly, especially if the generator is not used frequently. Additionally, standby generators are also more expensive to purchase than portable generators.
Permanent generator, also known as a prime power generator, are installed and connected permanently to the facility and they can be run continuously. This type of generator is mainly used in remote places that have no access to power grid or during construction projects and they will be the main power source.
