The KOHLER RESV 12,000-Watt Dual Fuel Home Standby Generator is engineered to provide reliable, fully automatic backup power for essential home circuits, appliances, and select electrical systems during utility outages. Designed to operate on either liquid propane or natural gas, this generator offers fuel flexibility and dependable performance.
As part of Kohler’s Quiet Series (denoted by QS8), the 12RESV-QS8 features enhanced sound-dampening design elements for quieter operation compared with standard standby units. This model is intended to be installed with a properly sized automatic transfer switch (sold separately unless otherwise specified), enabling automatic detection of utility power loss, generator start, and safe load transfer — then returning to utility power when service is restored.
This unit is ideal for homeowners seeking a reliable standby solution for critical circuits and moderate load support without oversizing capacity.
