How to Choose the Right Generator Running Cover
Material and Waterproofing
The primary job of a running cover is to be completely waterproof. Look for terms like “heavy-duty tarpaulin,” “900D Oxford fabric,” or “double-layer PVC-coated polyester.” These materials are designed to repel water effectively under pressure from rain or melting snow. The thickness, often denoted by a “D” (denier) number, indicates fabric density and generally correlates with durability. A robust material also resists tears, UV damage, and wind stress over time.
Beyond the fabric itself, examine the construction. Sealed or welded seams are crucial to prevent water from seeping through stitch holes. Some premium covers, like the GenArmor Generator Covers While Running, feature patented waterproof designs validated for severe conditions. Proper material choice ensures your generator stays dry, preventing electrical hazards and corrosion. For long-term protection when the generator is off, consider pairing your running cover with one of the best generator storage covers.
Ventilation and Heat Dissipation
Generators produce significant heat and exhaust fumes while operating. A good running cover must manage this heat buildup to prevent overheating, which can damage the engine and pose a fire risk. Designs address this with strategic ventilation. Some models feature a vented top panel to create a chimney effect, allowing hot air to escape while drawing in cooler air from the bottom.
Other designs, like the NGB Generator Runing Cover, use roll-up side panels. This lets you open sections to increase airflow around the control panel and engine block while keeping the top shielded from rain. Always ensure the cover you select has a clear, safe path for exhaust to exit without being trapped inside the enclosure. Proper ventilation is non-negotiable for safe operation.
Compatibility and Fit
A cover that is too small won’t fit, and one that is too large can flap in the wind, potentially compromising its seal and stability. Manufacturers provide wattage ranges (e.g., 4000W–13000W) and physical dimensions for compatibility. The most accurate method is to measure your generator’s footprint and height, including handles and wheels, and compare it to the cover’s internal dimensions.
Pay attention to the frame style of your generator. Heavy-duty tent-style covers, such as the Westinghouse WGenTent Generator Running Cover, are often designed for open-frame generators. Soft covers with integrated frames or straps may be better suited for inverter generators or models with a more compact profile. Checking the fit before you buy saves hassle and ensures optimal protection. You can find more information on protecting different generator types in our portable generators category.
Access and Convenience Features
You need to refuel your generator, check the oil, and plug in cords without struggling with the cover. Well-designed models incorporate dedicated access points. Look for features like a refueling door with a waterproof zipper or flap, as seen on many top models. This allows you to add fuel quickly without exposing the entire generator.
Other useful features include external pockets for storing power cords or tools, roll-up windows for control panel access, and secure attachment systems. These can be buckle straps, drawstrings, or velcro closures that keep the cover snug in high winds. Easy setup is also key, especially in an emergency; some covers offer tool-free assembly. For securing your entire setup, review our article on the best generator storage boxes.
