Sizing done right
Undersized generators shed loads; oversized generators cost more up front and use more fuel. A proper load calc weighs your HVAC compressor (biggest single load), well pump if applicable, kitchen loads, EV charger, and critical circuits to arrive at the right kW rating.
Automatic Transfer Switch (ATS)
Generac's Guardian ATS senses utility loss and transfers the home to generator power in ~10-20 seconds. Whole-house ATS covers the entire panel; managed load ATS with priority load management is common for larger homes on smaller generators.
What's included
Generator unit, ATS, composite or concrete pad, gas coordination (line sizing, connection), permit and inspection, commissioning, load testing, and homeowner walkthrough.
