FAQ
When a power outage occurs, a UPS will immediately switch to battery power to provide a continuous power supply to connected equipment. However, the UPS batteries have a limited runtime, so a generator is needed to provide long-term power protection. When initiated the UPS will send a signal to the generator to start up. Once the generator is running, the UPS will switch to generator power. When the power outage is over and grid power is restored, the UPS will return to utility power and recharge its batteries. The generator will then shut down.
