Portable generators are extremely useful for providing backup power during power outages. However, these invaluable machines are susceptible to weather damage if left unprotected from the elements. Getting your generator wet can lead to serious mechanical issues and electrical hazards. In this blog post, we'll explore whether portable generators can get wet safely, how to properly protect them from rain and moisture, and tips for operating generators in wet conditions.

Can Portable Generators Be Exposed to Water?

In general, portable generators are not designed to withstand getting soaked with water. The engine, fuel system, and electrical components can be damaged by excessive moisture. Most manufacturer manuals expressly warn against exposing generators to rain or snow. However, generators can tolerate some light moisture, such as high humidity or light rain. Brief exposure to minimal amounts of water is unlikely to cause immediate issues. But the generator frame and exterior can safely get partially wet periodically. It's prolonged contact with heavy rain, splashing, or submersion in water that puts a portable generator at risk of damage and dangerous electrical failures. Let's look at the potential risks of water exposure:

  • Shorting out or corrosion of electrical components
  • Fuel contamination and engine flooding
  • Stalling and failure to start
  • Rusting and deterioration of metal parts
  • Damage to insulation on wiring

Clearly, it's important to limit a portable generator's contact with moisture. But what's the best way to protect generators from the elements while still allowing them to run properly?

How to Shelter Your Portable Generator from Rain?

Here are some effective methods to keep your portable generator dry during wet weather:

Use a Generator Enclosure or Shed

A dedicated generator enclosure is ideal for shielding your unit from rain and snow. Look for weather-resistant enclosures made specifically for generators that allow for airflow while blocking moisture. Just make sure to allow the generator to cool down before storing it in an enclosure while hot. You can also build a simple generator shed using waterproof materials. Make sure it is well-ventilated to prevent overheating.

Use a Canopy or Tarp

For temporary protection, use a waterproof tarp or outdoor canopy. Secure it above the generator to provide dry coverage. Make sure the generator has clearance from the cover to prevent overheating. Avoid wrapping the generator tightly in plastic sheeting which can cause it to overheat.

Place the Generator on an Elevated, Dry Surface

Set your generator on wood planks or concrete blocks to raise it above wet ground. You want a dry surface that won't get soaked or muddy during rain. This prevents splashing and puddling under the unit.

Be Careful With Extension Cords

When running extension cords from a sheltered generator, be mindful of moisture collecting on the wires. Try to minimize cord length and secure connections. Inspect cords for safe operation if they do get wet.

Use a Generator Pad or Gravel Surface

For more permanent outdoor generator setups, install a generator pad or gravel base. This elevates the unit above the dirt and improves drainage underneath. Prevent puddles and soggy ground conditions around the generator.

Regularly Check Weather Forecasts

Keep an eye on upcoming weather so you can take proactive steps to protect your generator if heavy rain or snow is expected. Don't let it get overtaken by an unexpected downpour.

Follow the Manufacturer's Instructions

Review your generator manual for any additional recommendations on preventing water damage and operating in wet conditions. Follow all guidelines to avoid voiding your generator warranty.

Tips for Safely Running a Generator in the Rain

If you do need to use your portable generator in rainy or snowy weather, here are some safety tips for use in the rain:

  • Wipe down the generator to remove any moisture when stopping operation.
  • Ensure electrical components are not directly exposed to rain while running.
  • Check that the generator is level and stable on wet ground.
  • Allow the generator engine to warm up before connecting appliances.
  • Be prepared to move the generator into a dry location if conditions worsen.
  • Listen for any abnormal sounds or signs of electrical issues.
  • Never operate a generator with damaged cords in wet conditions.
  • Use a ground fault circuit interrupter (GFCI) for protection against shocks.
  • Avoid directly touching a wet generator during operation - you could get electrocuted.

The ideal solution is to keep your generator away from rain exposure entirely. But taking proper precautions can minimize the risks if the operation in wet weather is unavoidable. Always put safety first.

When to Service or Repair a Wet Generator?

If your portable generator does get significantly wet, it's important to have it looked over by an experienced technician before restarting it. They can check for any water damage and make necessary repairs.

Signs you may need generator service after water exposure include:

  • The generator will not start.
  • You hear abnormal grinding, popping, or banging sounds.
  • Electrical components got directly soaked or splashed.
  • You detect burned or singed insulation on wires.
  • There is visible corrosion on connectors or the frame.
  • Condensation or moisture inside the generator housing.
  • Dirt or water in the fuel tank and engine.

Don't take risks trying to operate a generator with probable water damage. Professional repairs by a qualified technician can get your generator running safely again after drying it out thoroughly.

Use Caution to Keep Your Generator Dry

Portable generators and excess moisture don't mix well. To prevent generator failure or dangerous electrical incidents, it's critical to keep your unit sheltered from the elements. While generators are designed to withstand some humidity and light rain, heavy downpours require proactive protection steps. Follow the manufacturer's guidelines, allow proper ventilation, and exercise caution when using generators in wet weather. With smart precautions, you can avoid unnecessary damage and safely power through outages - rain or shine.
