Generac Guardian 13kVA will guard your home or small business around the clock. Connected to your existing natural gas or LP supply, the generator will detect a power outage and kick in within just seconds. And the best part it, you don’t even need to be at home! The automatic transfer switch will switch your home’s power supply to the generator, and back again when the mains power resumes. It doesn’t miss a beat – which means your home’s appliances and devices won’t either.
