Essential for keeping your business running in a power cut, standby generators replace the now absent mains power. It is important to spec these generators to want they are required to support when purchased, so you aren't disappointed when you really need them. Standby generators can be used in conjunction with a UPS so there is no break in the power.
A standby generator is a backup electrical system that operates automatically, within seconds of an outage an automatic transfer switch senses the power loss and starts the generator. The standby generator then begins supplying power to the circuits. After utility power returns, the automatic transfer switch transfers the load back to the mains and signals the standby generator to shut off.
