How standby generators work

The automatic transfer switch monitors utility power 24/7. When an outage is detected, the generator starts within 10-30 seconds and takes over. When utility power returns, it automatically shuts down.

Choosing the right size

Add up the wattage of everything you want to power during an outage. Essential circuits (fridge, HVAC, well pump) typically need 14-16kW. Whole-house coverage with AC usually requires 20-22kW or more.
