Buying Guide: Weather Covers For Generators
What should you consider when choosing a generator cover? Start with size and fit. Measure your generator’s length, width, and height, and compare to cover dimensions. Coverage should reach beyond the unit’s extremities to prevent wind-driven rain from entering.
Material and durability
Look for a 600D or higher polyester with a water-resistant laminated undercoating. Sealed seams and reinforced stitching improve tear resistance and weatherproofing. If your location has heavy winds or snow, a tougher frame or extra security features help maintain position.
Protection features
Consider double stitching, taped seams, UV resistance, and pocket vents if you store the unit outdoors for extended periods. A drawstring or elastic bottom helps keep the cover secure during gusts.
Installation and maintenance
Choose a design that’s easy to install and remove for regular generator checks. Clean covers periodically with mild soap and water to prevent mold and mildew buildup. Avoid harsh chemicals that may degrade fabric over time.
Ventilation and accessibility
Some covers balance protection with access panels or openings for air circulation. If you need to perform routine checks or maintenance, ensure the cover allows quick access to handles, fuel ports, or exhaust structures without removing the entire cover.
Climate and location considerations
In snowy regions, look for covers with windproof features and a snug fit. In sunny climates, UV-resistant materials prolong fabric life. For coastal areas, consider water resistance against salt spray and corrosion potential.
