Who Should Buy This Cover: Homeowners with backup generators, contractors with outdoor equipment, and anyone seeking reliable all-weather protection for mid-to-large size generators. Ideal for areas with frequent rain, intense sun, or harsh seasonal weather.
Key Considerations Before Purchasing: Measure your generator's length, width, and height before ordering. This cover runs large, making it better suited for generators at the higher end of the 6,000-13,000 watt range. If your unit is smaller or has an unusual frame design, verify compatibility or consider a smaller cover size.
Installation and Use: The cover features intuitive fastening with clearly marked straps and Velcro points. For operational use, lift the front curtain panel to access fuel and exhaust, then secure side Velcro closures. For storage, fully enclose the unit and tighten all straps. In windy conditions, tension all straps firmly to prevent displacement.
Maintenance: Rinse the cover periodically with mild water to remove debris and bird droppings. Allow to air dry completely before storage. The included carrying bag should be used for off-season storage to maintain material integrity.
Warranty and Support: Verify current warranty terms with the manufacturer. Quality construction suggests good longevity, but proper fastening and seasonal maintenance will maximize the cover's lifespan.
How to Choose the Right Generator Weather Cover
Material and Durability
The fabric denier (D) rating indicates material thickness and strength. Common ratings are 420D, 600D, and 900D, with higher numbers generally being more robust. Look for covers made from polyester or Oxford fabric with a waterproof laminated coating. Double-stitched seams and taped edges are critical for preventing leaks and tears over time, ensuring the cover lasts for seasons.
For the ultimate in material strength, the best generator storage covers often use heavy-duty tarpaulin or thick Oxford cloth. This construction resists abrasion from wind-blown debris and the sun’s degrading UV rays, providing comprehensive all-weather protection for your equipment.
Storage vs. Running Covers
This is the most critical distinction. Standard storage covers, like the Generator Cover for 5000 ‑10000W, are only for use when the generator is off and cool. They simply shield it from the elements. Running covers, such as the GenArmor Generator Covers While Running, are engineered enclosures with frames and vents.
These allow safe operation in rain or snow by managing exhaust, providing airflow for cooling, and offering access for refueling. Never use a storage cover on a running generator, as it poses a severe fire risk and can cause dangerous overheating.
Fit and Secure Attachment
Always measure your generator’s length, width, and height before purchasing. A proper fit prevents flapping in the wind, which can wear the fabric and expose your generator. Look for features like adjustable drawstrings, elastic hems, and Velcro straps at the bottom.
These elements create a snug, secure fit that keeps the cover in place during high winds. For added security where you store your generator, consider pairing your cover with one of the best generator security cables.
Ventilation and Access
Even for storage, some ventilation is beneficial to prevent moisture buildup and condensation under the cover, which can lead to rust. Some storage covers feature mesh panels or side vents. For running covers, ventilation is non-negotiable. Designs include vented tops, open bottoms, and specific access panels.
These panels allow you to reach the control panel, outlets, and fuel cap without removing the entire enclosure. This is a vital safety feature during severe weather. Proper ventilation also works in tandem with accessories like a generator exhaust extension to direct fumes safely away from living areas.

Frequently Asked Questions
Can I use a regular tarp as a generator cover?
While a tarp offers basic protection, it is not ideal. Tarps lack a tailored fit, often leading to moisture trapping and wind damage. Dedicated generator covers are made from UV-resistant, waterproof materials with sewn seams and secure fasteners designed for the specific shape and heat of a generator, providing far superior and safer protection.
How do I know if a cover will fit my portable generator?
Always check the manufacturer’s size chart and measure your generator’s dimensions (L x W x H). Measure at the widest points, typically including the frame but excluding handles and wheels. Most covers list compatible wattage ranges and specific model examples. When in doubt, choosing a cover slightly larger than your exact measurements is better than one that is too tight. For more on sizing equipment, see our guide to portable generators.
What is the difference between a waterproof and water-resistant cover?
Water-resistant fabric can repel light rain for a short time but may eventually allow water to seep through under sustained exposure. A truly waterproof cover has a laminated or coated layer that prevents water penetration entirely, even during heavy downpours. For reliable outdoor storage or running use, a verified waterproof rating is essential.
Do I need a special cover for a home standby generator?
Most home standby units are installed inside a dedicated, vented enclosure and do not require a separate fabric cover. The primary focus for these systems is ensuring the installed enclosure is properly rated for weather. The covers reviewed here are primarily for portable and inverter generators.
