Not every home or business has access to natural gas, that should never stop you from having reliable backup power.

Why Propane Is an Excellent Generator Fuel

Higher Energy Density = More Power

Reliable in All Conditions

Professional Propane Tank Installation

120-Gallon ASME Propane Tank (Popular Generator Size)

At Southern Power Generators, we offer propane-powered standby generator systems for both residential and commercial properties. If your property does not have a natural gas line, we can professionally install a propane tank and seamlessly connect it to your Generac standby generator, ensuring your backup power system runs efficiently, safely, and at peak performance.

Propane is widely used for standby generators because it delivers strong performance, reliability, and flexibility.



Propane contains more British Thermal Units (BTUs) per cubic foot than natural gas. This higher energy density allows generators to produce more power using less fuel. Because of this, generator manufacturers often list their maximum kilowatt (kW) output when running on propane, highlighting the generator’s top performance capability.

✔ Propane maintains efficiency in freezing temperatures
✔ Starts reliably during winter outages
✔ Does not degrade over time like gasoline
✔ Ideal for standby generators that may sit unused for long periods

Ideal Applications for Propane Generator Systems

Propane tank–powered generators are a great solution for:
✔ Homes without natural gas service
✔ Rural and off-grid properties
✔ Senior living communities
✔ Medical offices and clinics
✔ Small businesses and commercial buildings
✔ Homes requiring high electrical demand during outages

We install ASME-certified propane tanks designed specifically for stationary generator applications. These tanks are commonly used for whole-home and commercial standby generators.

Key Features:
✔ 120-gallon capacity for extended generator runtime
✔ ASME-rated (no recertification required after 12 years)
✔ Above-ground or code-compliant installation
✔ Built-in propane float gauge (remote-ready upgrade available)
✔ Heavy-duty powder-coated steel for corrosion resistance
✔ Secure fill, service, and relief valves
✔ Protective lid included
✔ ASME tanks are vacuum-purged, hydrostatic tested, and X-ray         inspected to meet strict safety standards.
