Introduction
When your generator kicks into action during a power outage or outdoor event, the last thing you want is for weather, debris, or excessive noise to interfere with its performance. Generator covers designed for running generators solve these problems while keeping your equipment safe and operational.
A generator cover while running serves as a protective barrier that shields your equipment from rain, snow, wind, and other environmental hazards without compromising airflow or performance. Unlike storage covers that require you to shut down your generator, running covers feature strategic ventilation systems and heat-resistant materials that allow safe operation while maintaining protection.
Understanding how to select and use the right generator cover can extend your equipment’s lifespan, reduce maintenance costs, and ensure reliable power when you need it most. This guide will walk you through everything you need to know about generator covers for running units, from types and benefits to installation and maintenance.
Why Use a Generator Cover While Running?
Weather Protection
Rain and moisture pose serious threats to your generator’s electrical components and engine. Water infiltration can cause short circuits, rust formation, and permanent damage to sensitive parts. A quality running cover creates a weatherproof shelter that deflects precipitation while maintaining proper ventilation for cooling and exhaust.
Snow presents additional challenges, as accumulation can block air intakes and exhaust outlets. Generator covers prevent snow buildup on critical components and maintain clear pathways for airflow. Wind protection is equally important, as strong gusts can blow debris into moving parts or disrupt the generator’s stability.
Noise Reduction
Generator noise can strain relationships with neighbors and violate local noise ordinances. Running covers incorporate sound-dampening materials that significantly reduce decibel levels without restricting airflow. The enclosed design helps contain engine noise and vibrations, creating a more pleasant environment for everyone nearby.
Many covers feature multi-layer construction with acoustic foam or mass-loaded vinyl that absorbs sound waves. This noise reduction proves especially valuable for residential applications, camping trips, or events where quiet operation is essential.
Enhanced Safety
A generator cover while running creates a protective barrier between hot surfaces and people or pets who might accidentally make contact. Running generators produce intense heat, and exhaust components can cause severe burns. The cover acts as a safety shield while maintaining proper ventilation to prevent overheating.
Covers also protect against accidental contact with moving parts and electrical connections. This added layer of safety becomes crucial in households with children or in public settings where multiple people may be present.
Types of Generator Covers for Running Units
Soft Covers
Soft generator covers use flexible materials like vinyl, polyester, or canvas with weather-resistant coatings. These covers typically feature zippered panels for easy access to controls and maintenance points. The lightweight design makes them portable and easy to store when not in use.
Most soft covers include reinforced grommets for tie-down points and elastic hems for secure fitting. While less expensive than hard covers, they may not provide the same level of durability or noise reduction. Soft covers work well for occasional use and smaller portable generators.
Hard Covers
Hard covers utilize rigid materials such as aluminum, steel, or high-density plastic to create a permanent shelter structure. These covers offer superior protection from impacts, extreme weather, and attempts at tampering or theft. The solid construction provides excellent noise reduction and can include features like hinged doors, ventilation fans, and locking mechanisms.
Hard covers often resemble small sheds or enclosures and may require assembly or professional installation. While more expensive initially, they provide long-term value through enhanced protection and security features.
Custom-Built Covers
For unique installations or specific requirements, custom-built covers offer the perfect fit and optimal functionality. These covers can incorporate specialized ventilation systems, remote monitoring capabilities, and aesthetic designs that blend with your property’s appearance.
Custom options allow you to specify materials, colors, access points, and additional features based on your exact needs. Professional fabrication ensures proper engineering for ventilation, structural integrity, and compliance with local building codes.
Factors to Consider When Choosing a Generator Cover
Generator Size and Configuration
Accurate measurements are essential for proper cover selection. Measure your generator’s length, width, and height, including any protruding components like handles, fuel tanks, or control panels. Allow additional space for ventilation clearances as specified by the manufacturer.
Consider the generator’s exhaust location and ensure the cover design accommodates proper exhaust routing. Some generators have top-mounted exhausts while others exit from the side or rear. The cover must maintain adequate clearance from hot exhaust components.
Environmental Conditions
Assess your local climate and weather patterns to determine protection requirements. Areas with heavy rainfall need covers with superior water resistance and drainage features. Regions with high winds require secure anchoring systems and aerodynamic designs that won’t catch wind or create lift.
Temperature extremes affect material selection, as covers must withstand both freezing conditions and intense heat from the generator. UV exposure in sunny climates demands fade-resistant materials that won’t become brittle over time.
Portability Requirements
Portable generators used for camping, construction, or emergency response need covers that are lightweight and easy to transport. Look for designs that fold compactly or include carrying cases for convenient storage and transport.
Stationary installations can accommodate heavier, more substantial covers that prioritize protection over portability. Consider whether you’ll need to move the cover frequently for maintenance access or seasonal storage.
Step-by-Step Installation Guide
Preparation
Start by selecting a level, stable surface for your generator that allows adequate clearance on all sides. Ensure proper distance from buildings, windows, and combustible materials as specified in your generator’s manual. Clean the installation area of debris and verify that drainage is adequate.
Read through the cover manufacturer’s instructions completely before beginning installation. Gather all required tools and hardware, and inspect all cover components for damage or missing parts.
Cover Assembly
If using a soft cover, lay it out flat and identify all access panels, zippers, and attachment points. For hard covers, follow the manufacturer’s assembly sequence, typically starting with the base or frame components.
Ensure all connections are secure and that moving parts like hinges or latches operate smoothly. Apply any recommended sealants or weatherproofing treatments during assembly.
Final Installation
Position the cover over your generator, ensuring adequate clearance around hot components and proper alignment with access panels. Secure all attachment points, including tie-downs, stakes, or mounting hardware.
Test all access points to verify you can reach controls, fuel fill points, and maintenance areas without removing the entire cover. Check that ventilation openings are unobstructed and properly positioned.
Maintenance Tips for Generator Covers
Regular Cleaning
Clean your generator cover monthly or after severe weather events. Use mild soap and water for most materials, avoiding harsh chemicals that might damage protective coatings. Pay attention to ventilation screens and drainage areas where debris tends to accumulate.
Inspect seams, zippers, and attachment points during cleaning to identify wear or damage early. Address minor issues promptly to prevent more extensive problems that could compromise protection.
Seasonal Maintenance
Before winter storage, thoroughly clean and dry the cover to prevent mold or mildew formation. Apply appropriate protective treatments for the cover material, such as vinyl conditioner or fabric waterproofing spray.
Spring preparation should include inspection of all hardware, replacement of worn components, and testing of drainage systems. Ensure ventilation screens are clear and that no winter damage has occurred to the structure.
Storage Considerations
When storing soft covers, fold them loosely to prevent creasing and cracking. Store in a dry location away from direct sunlight and extreme temperatures. Hard covers should be inspected for any structural damage and protected from corrosion if made from metal materials.
