Buying Guide: Key Considerations For Liquid Propane Generators
- Fuel compatibility: Confirm whether the unit supports liquid propane specifically, and if it can switch between propane and other fuels if needed.
- Power needs: Calculate essential loads and determine whether a standby (permanent) model or portable generator best fits your home or property.
- Transfer switch: Decide between automatic transfer switches (for seamless outages) and portable options (for temporary setups). Check the TS rating and compatibility with your electrical panel.
- Run time and fuel availability: Review tank size or fuel storage requirements and typical run-time at your expected load. Propane supply planning is important for prolonged outages.
- Noise and footprint: Consider units with Quiet-Test modes or lower RPM operation for better neighborhood compatibility and indoor comfort.
- Safety features: Look for CO alerts, over-current protection, and proper ventilation for indoor or semi-enclosed installations.
