Essential-load backup or a larger standby system?
Generator selection starts with the loads you need to operate and their starting demands. A refrigerator, lighting, communications, medical equipment, and a heating or cooling system can create very different priorities from a whole-property backup goal. Motor starting current can be significant, and some loads can be managed rather than supplied simultaneously. A properly developed load plan is more useful than choosing a unit solely by house size.
The pictured Generac Guardian is an actual standby generator product example. Generac, Kohler, and Cummins offer different residential and commercial families, with model-specific ratings and requirements. Generator output can vary with fuel type and operating conditions, so compare the exact specifications rather than a headline rating. A proposal should distinguish the generator, transfer equipment, fuel work, pad or support, permits, and any load-management equipment.
