Quick Answer
The right propane tank size for a standby generator depends on the generator, expected usage and the requirements of the property. There isn't one tank size that's appropriate for every homeowner.
This is why selecting a tank should be part of planning the overall backup-power system.
Why Propane Tank Size Matters
When the electricity goes out, your standby generator needs an adequate fuel supply to operate.
Simply choosing a tank based on what you have seen at another home may not account for the demands of your particular generator or property.
Instead, propane tank planning should consider how your entire system will be used.
What Determines the Right Propane Tank?
Several factors can influence the appropriate solution.
1. Your Generator
Different equipment can have different fuel requirements. Your specific generator is one of the first things to consider when evaluating its propane supply.
2. How You Expect to Use Your Generator
Backup-power needs vary. Some homeowners may be preparing primarily for relatively brief outages. Others want a system capable of supporting the home through longer interruptions. Expected usage can therefore be an important consideration.
3. Other Propane-Powered Equipment
Will the tank supply only your generator? Or will propane be used elsewhere on the property? The answer can influence your overall propane requirements and should be discussed when planning the installation.
4. Your Property
Tank installation is not determined solely by capacity. Available space, proposed tank location and other property-specific factors may affect the installation.
Should I Select My Generator or Propane Tank First?
If you're planning a new generator installation, the generator and its propane supply should be considered as parts of the same backup-power system.
