Buying Guide for 15 Kw Propane Generators
Choosing the right 15 kW propane generator involves considering several important factors to ensure it meets your power needs effectively and safely.
Power Output and Running Watts
Understand the difference between peak (surge) watts and running (continuous) watts. Peak watts are necessary for appliances requiring a startup surge, like air conditioners, while running watts indicate sustained power supply. Ensure your chosen generator’s running watts cover the critical appliances you intend to power simultaneously.
Fuel Type and Flexibility
Dual fuel (gasoline and propane) or tri-fuel (adding natural gas) options offer versatility. Propane is popular due to its clean-burning nature and longer shelf life, reducing maintenance needs. Generators that support multiple fuel types allow greater convenience and cost-control based on availability.
Engine Quality and Features
Look for generators with OHV (overhead valve) engines and durable components like cast iron sleeves or all copper windings. These design elements enhance engine longevity and reliability. Features such as low oil shutdown and CO alert increase safety during operation.
Starting Mechanism
Electric start with remote key fob adds convenience, especially during emergencies. Recoil start is a good backup feature if electric start fails. Choose a model that balances user-friendliness and reliability.
Transfer Switch Compatibility
If your goal is whole home backup power, ensure the generator supports transfer switch connections for safe integration with your home’s electrical panel. This feature is critical for seamless power transition during outages.
Portability and Runtime
The generator’s weight, wheels, and handle design impact its mobility. Run time depends on fuel tank size and efficiency; models capable of extended run times minimize refueling interruptions during extended power outages.
Outlet Selection
Verify the range and types of outlets—standard household, RV-ready, 240V outlets—to match your needs. Outlets with covers and GFCI protection increase safety.
