Buying Guide for Weatherproof WEN Generators
Generator Type and Power Output
Your first decision is between a conventional portable generator and an inverter model. Inverter generators, like the WEN 3600-Watt Portable Inverter Generator, provide clean, stable power ideal for sensitive electronics. They are often quieter and more fuel-efficient. Conventional models, such as the WEN 5600-Watt Portable Generator, offer higher raw power output for running larger appliances or tools. Match the wattage to your essential needs, considering both starting and running watts.
Weatherproofing and Protection Features
Portability and Convenience
Consider how you will move and store your unit. Built-in wheel kits and telescoping handles, featured on models like the WEN 4,750-Watt Dual Fuel, are crucial for heavier generators. Lighter inverter models prioritize easy carrying. Features like a fuel shutoff valve help with maintenance and storage, prolonging the engine’s life. Convenient outlet panels with USB ports and RV-ready plugs add significant utility for various applications.
Fuel Options and Runtime
Fuel flexibility can be a major advantage. Dual fuel generators, such as the WEN 4,750-Watt 120V/240V Dual Fuel, allow you to switch between gasoline and propane based on availability and storage preferences. Assess the fuel tank capacity and published runtime at half load to understand how long the generator will operate between refueling. This is critical for extended power outages or camping trips where fuel access may be limited.
True weatherproofing involves both the generator’s built-in design and added protection. Look for models with robust, sealed construction where possible. The most critical step is using a dedicated, fitted cover like the WEN 56413 Universal Weatherproof Generator Cover. A proper cover features a waterproof and UV-resistant exterior with a soft interior lining to prevent scratches. It is a simple, affordable way to shield your generator from rain, snow, and sun damage. For generators with specific safety outlets, you can read about WEN generators with GFCI outlets.

Frequently Asked Questions
Are WEN generators actually waterproof?
While WEN generators are built with durable materials, they are not fully waterproof or submersible. They are designed to be weather-resistant, but prolonged direct exposure to rain or snow can cause damage. Using a dedicated WEN weatherproof cover, like the WEN 56200iC Universal Weatherproof Inverter cover, is strongly recommended to provide a waterproof barrier and shield the unit from the elements during storage or use in light precipitation.
Can I leave my WEN generator outside all year?
It is not advisable to leave any generator outside permanently without protection. Even with a high-quality cover, constant moisture and temperature extremes can lead to corrosion and engine problems over time. For long-term storage, keep your generator in a dry, well-ventilated shed or garage. When in use during inclement weather, a cover provides critical short-term protection. You can find more brand insights on our WEN Generators category page.
What size weatherproof cover do I need for my WEN generator?
WEN offers covers in specific sizes tailored to their generator lines. Match the cover to your generator’s wattage and physical dimensions. For example, the WEN 56310iC Universal Weatherproof Inverter cover is designed for 3800W to 4500W closed-frame inverter models. Always measure your generator and consult the cover’s size specifications before purchasing to ensure a snug, protective fit that won’t billow in the wind.
How do I maintain my WEN generator for wet weather use?
Beyond using a cover, regular maintenance is key. Always check that all access panels and the fuel cap are sealed tightly. After use in damp conditions, wipe the generator down to remove moisture before covering it. Follow the manufacturer’s schedule for oil changes and air filter checks, as a well-maintained engine is more resilient. Using a fuel stabilizer and running the carburetor dry with the fuel shutoff feature, found on models like the WEN 3600-Watt Portable Inverter Generator, helps prevent moisture-related fuel system issues.
