Liquid Propane (LP)
LP Consumption – 50% (ft³/hr): 65
At half load, the generator consumes 65 cubic feet of propane vapor per hour.
LP Consumption – 50% (gal/hr): 1.81
At half load, the generator consumes about 1.81 gallons of liquid propane per hour.
LP Consumption – 100% (ft³/hr): 112
At full load, it consumes 112 cubic feet of propane vapor per hour.
LP Consumption – 100% (gal/hr): 3.07
At full load, it uses approximately 3.07 gallons of liquid propane per hour.
Natural Gas (NG)
NG Consumption – 50% (ft³/hr): 195
When running at half load, the generator uses 195 cubic feet of natural gas per hour.
NG Consumption – 100% (ft³/hr): 256
At full load, it consumes 256 cubic feet of natural gas per hour.
Propane tanks are never filled to 100% due to expansion safety limits. They are typically filled to 80% capacity. So usable propane is:
250-gallon tank: 250 × 0.80 = 200 gallons usable
500-gallon tank: 500 × 0.80 = 400 gallons usable
1,000-gallon tank: 1,000 × 0.80 = 800 gallons usable
| Tank Size | Usable Gallons (80%) | Runtime @ 50% Load |
|---|---|---|
| 250 gallons | 200 | ~110.5 hours |
| 500 gallons | 400 | ~221 hours |
| 1,000 gallons | 800 | ~442 hours |
| Q: How does the weekly self-test work and can I monitor the system remotely? |
| A: Generac standby generators perform an automatic weekly or bi-weekly self-test (often called Quiet-Test). You can schedule the test window through the controller, and many models support mobile monitoring to view status, alerts, and maintenance reminders from your phone. |
| Q: What fuel supply do I need—natural gas or propane? |
| A: Most standby units run on either natural gas or liquid propane. A licensed installer will size the fuel line based on BTU demand, line length, and local code. Ensure your gas meter or LP tank can deliver the required flow at full load. |
| Q: Which transfer switch should I choose? |
| A: For whole-home coverage, a 200-amp service-rated automatic transfer switch (ATS) is common; for essential-circuits, a smaller ATS or load-shedding switch may be used. Your electrician will match the ATS to your service size and whether you want whole-home or select-circuit backup.” |
