GenTent Generator Tent Frequently Asked Questions
A generator running cover is a weather-protection system designed to allow portable generators to safely operate outdoors during rain, snow, and severe weather. Unlike tarps or DIY shelters, engineered generator tents maintain safe airflow while protecting electrical outlets and control panels from moisture.
Yes — but only with proper protection. Portable generators should not operate exposed to rain or snow because water can damage electrical components and create shock hazards.
With a properly engineered generator running cover, large generators such as the Westinghouse WGen20000, 28,000-watt class portable generators, or high-output inverter generators like the DuroMax XP28000iH can safely operate in rain or storm conditions while maintaining proper ventilation and airflow.
GenTent generator tents use waterproof marine-grade vinyl canopies and a raised frame structure that sheds rain and snow while keeping the generator’s control panel and outlets protected during operation.
Portable generators must always operate outdoors. Place your generator on a stable, level surface at least 20 feet away from your home, with the exhaust directed away from doors, windows, and vents.
Never operate generators in garages, basements, under decks, or in enclosed spaces. Even partially enclosed areas can allow carbon monoxide to enter a home.
A GenTent running cover allows the generator to remain outdoors while protecting it from rain, snow, and severe weather during operation.
No. GenTent systems are designed so the canopy can remain installed while accessing the fuel cap. The raised frame structure keeps the canopy elevated above the generator, allowing normal access to controls and fueling points.
For safety, always turn the generator off and allow the engine to cool before refueling. Spilled fuel on a hot engine can ignite.
Yes. GenTent generator tents are independently lab tested for extreme weather conditions including heavy rain, high winds, and snow loads. Each canopy is built with flame-retardant materials meeting NFPA-701 standards.
GenTent generator tents are assembled in the United States at our facility in Brentwood, New Hampshire using globally sourced materials designed for durability and weather protection.
