Your portable generator is a reliable and easy-to-use power source with many applications, but severe weather significantly reduces its usability. We’ve got good news—you can cover your generator while it’s running. Prepare your portable generator for extreme weather while maintaining portability with a GenTent generator tent. 

Rain, snow, lightning and other severe weather can damage a generator, but keeping the generator in your garage, even with the door open, can increase your danger of carbon monoxide exposure. A generator tent allows you to safely store your power source outside, even in inclement weather. With an operational generator tent, you can cover your generator while it’s running and keep it safe from wind, rain, and snow. We offer different types of covers for generators of all types and sizes.

Waterproof Generator Rain Cover and Accessories

GenTent provides various accessories to help keep your generator running while it’s covered, ensuring that it’s safe from any weather event. Whether you want to be prepared if your house loses power during a severe storm or you need a safe and portable power source for your RV, we have a tent to serve your needs. Here are the products we offer:

• Portable generator tents: These tents attach to the vertical frame posts of generators ranging from 70 to 104 inches in perimeter. You can choose from a direct connect kit or a universal kit depending on the needs and size of your generator.
• Inverter generator tents: Inverter generators often lack posts, so this kit includes a ratcheting strap system and adjustable rods to fit generators ranging from 45 to 120 inches in perimeter.
• Larger generator tents: If you have a larger generator with a perimeter of 100 to 128 inches, you can use these tents to attach to vertical posts and provide shelter for your power source.
• Accessories and spare parts: From storage bags to additional mounting hardware and even skirts for outside generator storage, GenTent carries everything you need for your generator.

What Goes Into an NFPA-Rated Generator Tent?

GenTent designs and assembles waterproof generator running covers that protect portable generators from rain, snow, and severe weather while they operate outdoors. These tents function as an NFPA-rated generator tent, helping shield electrical outlets and sensitive electrical components from precipitation while maintaining safe airflow and exhaust clearance during generator operation. A properly designed generator tent allows generators to stay protected from rain while maintaining the ventilation required for safe outdoor operation.

Each GenTent canopy is constructed from dual-coated marine-grade vinyl that protects generator control panels, outlets, and electrical components from moisture. The frame structure uses durable fiberglass rods and a secure mounting system that attaches directly to your generator’s frame. The flame-resistant canopy material is engineered to withstand temperatures ranging from approximately −45°F to 150°F while maintaining durability in severe outdoor environments.

The open-air tent design allows heat and exhaust gases to escape while the generator is running, helping prevent overheating and supporting reliable generator performance during storms or power outages. When power is restored, the generator cover can be removed or disassembled in minutes for easy portability. Whether you operate a food truck, power equipment across multiple construction sites, or prepare for emergency home backup power, GenTent provides portable generator weather protection that travels wherever your generator goes.
