Buying Guide
Fuel flexibility matters. If propane is your primary option, ensure the unit supports propane with a proper regulator and hose assembly. Tri-fuel models offer the broadest fuel accessibility, but require more components and maintenance.
Power needs matter. For whole-home backup, check both running watts and peak watts to ensure critical circuits stay powered. Consider transfer switch compatibility to connect to a home panel safely.
Durability and safety. Look for engines with copper windings and CO sensors or CO shuts-off features. Weather resistance or enclosure ratings are helpful for outdoor setups.
Ease of use. Remote start and digital displays simplify operation. Consider fuel tank size for expected runtime and whether extra accessories (wheel kits, covers) are included or sold separately.
Installation considerations. Some models support automatic transfer switches (ATS). If using natural gas, verify connection availability and regulatory compliance in your area.
