Now let’s look at key specifications like power output, fuel type, noise level and installation considerations when choosing a whole home unit.

Key Specs for Whole Home Backup Generators

Power Output

The power output needed depends on home size and circuits powered:

  • 16kW supports most homes up to 3,000 square feet
  • 20kW for larger homes up to 4,000 square feet
  • 24kW and above for big luxury houses with ample circuits

Consult an electrician to confirm your requirements. Remember to account for future expansion.

Fuel Types

Common whole home generator fuel sources:

  • Natural Gas – Taps into your existing home gas lines for unlimited runtime.
  • Propane – Requires a large external tank professionally installed and refilled.

Natural gas is the most convenient fuel, avoiding tank refills. But propane allows flexibility on generator placement as needed.

Installation

Whole home units require professional outdoor installation:

  • Mounted on a concrete pad with protective steel enclosure
  • Hardwired into your home’s electrical system with a transfer switch
  • Proper clearance from windows, doors, and ground level for ventilation
  • Adherence to all codes and obtaining required permits

Work with an authorized Generac dealer to ensure proper installation and functionality.
