How To Store Your Generator Or Inverter During The Off-Season

Generators and inverters are essential tools that provide power to homes, businesses, and outdoor events. Whether you use them for outdoor activities, backup power, or work purposes, these devices require proper care and maintenance to ensure that they last for many years. When they are not in use, it is important to store them properly to ensure their longevity and performance. In this blog post, we will discuss how to store your generator or inverter during the off-season.

Preparing for Long-Term Storage

Preparing your generator or inverter for long-term storage is crucial to ensure its longevity and performance when you need it. Follow these steps to prepare your unit for storage:

  1. One of the most critical steps in storing a generator or inverter is to drain the fuel tank. Old fuel can go bad and cause problems for your device, so it's essential to drain the tank completely. Run the device until it runs out of fuel completely, and then remove the fuel cap and drain any remaining fuel. Drain the fuel tank and carburetor to prevent fuel from sitting inside the engine and causing damage. You can even use a fuel stabilizer to keep the fuel fresh for up to 24 months. If your device has a carburetor, it's a good idea to spray it with carburetor cleaner to remove any residue.

  2. After draining the fuel, it's a good idea to change the oil in your generator or inverter. Change the oil and oil filter to remove any contaminants that could cause corrosion or damage to the engine. It is also important to clean or replace the air filter to ensure proper airflow when you start the generator or inverter. Old oil can become contaminated, so it's important to replace it before storing the device. Follow the manufacturer's instructions for changing the oil, and be sure to use the recommended oil type and grade.

  3. If your generator or inverter has a battery, it's essential to disconnect it before storing the device. Batteries can discharge over time and can be damaged by extreme temperatures. Disconnect the battery and store it separately in a cool, dry place.

Checking for Corrosion

Corrosion is a common problem when storing generators and inverters, especially if they are not properly protected from moisture. To prevent corrosion, follow these steps:

  1. Inspect your unit for any signs of rust or corrosion before storing it. Check the electrical connections, battery terminals, and other metal parts for signs of rust or damage.

  2. If you find any signs of corrosion, use a wire brush to remove the rust and apply a rust inhibitor to prevent further corrosion. You can also use a silicone lubricant on the electrical connections to protect them from moisture.

Ensuring it is Clean and Dry

Keeping your generator or inverter clean and dry is essential to prevent damage and ensure its longevity. Before you store your generator or inverter, it is crucial to clean it thoroughly to remove any dirt, dust, or debris. Follow these steps to clean and dry your unit:

  1. Thoroughly clean your unit to remove any dirt, debris, or grime that could cause damage or corrosion. Use a soft brush or cloth to remove any dust or dirt, and use a gentle soap solution to clean any stubborn stains. Pay attention to any vents or openings, as these can become clogged with dust or debris.

  2. After cleaning, make sure your unit is completely dry before storing it. You can use compressed air or a hairdryer on a cool setting to remove any moisture from the engine and other components.

Storing in a Dry and Secure Location

Storing your generator or inverter in a dry and secure location is crucial to protect it from the elements and other potential hazards. Follow these steps to store your unit properly:

  1. Store your unit in a garage, shed, or other covered area that protects it from the elements. Make sure to cover your unit with a waterproof cover like a tarp or plastic sheet to prevent moisture from entering the engine or other components. It's essential to store it in a dry place. Moisture can cause rust and other damage to the device, so it's important to keep it in a dry area.

  2. Store your unit in an upright position to prevent fuel or oil leaks. You can also use a fuel stabilizer to prevent any remaining fuel from evaporating or becoming stale.


Storing your generator or inverter properly during the off-season is essential to ensure that it lasts for many years. By following the steps outlined above, you can keep your device in good condition and ready for use when you need it. By taking these simple steps, you can extend the life of your generator or inverter and ensure that it's always ready when you need it.
