Storing a 15kW diesel generator during the off - season is a critical practice that can significantly impact the generator's lifespan and performance. As a supplier of 15kW diesel generators, I've witnessed firsthand the importance of proper storage procedures. In this blog post, I'll share some valuable insights on how to store your 15kW diesel generator effectively during the off - season.
Pre - storage Preparation
Before you store your 15kW diesel generator, it's crucial to conduct a thorough inspection and perform some necessary maintenance tasks. This will help prevent any potential issues that could arise during storage.
-
Clean the Generator: Start by cleaning the exterior of the generator to remove dirt, debris, and any other contaminants. Use a soft brush or a cloth to clean hard - to - reach areas. A clean generator is less likely to develop corrosion and other problems during storage.
-
Check the Fluids: Examine the engine oil, coolant, and fuel levels. If the engine oil is dirty or has reached its service interval, it's advisable to change it. Old oil can break down and cause damage to engine components over time. For coolant, ensure that it is at the proper level and that there are no signs of leaks. As for fuel, you have two options: either drain the fuel tank completely or add a fuel stabilizer. A fuel stabilizer can prevent the fuel from oxidizing and forming gum and varnish deposits, which can clog the fuel system.
-
Inspect the Battery: The battery is an essential component of the generator. Check the battery terminals for corrosion and clean them if necessary. You can use a mixture of baking soda and water to clean the terminals. If the battery is old or weak, it's a good idea to replace it before storage. Additionally, you can disconnect the battery to prevent it from discharging during storage. However, if you choose to leave the battery connected, it's recommended to use a battery maintainer to keep the battery charged.
-
Check the Air Filter: A clogged air filter can restrict airflow to the engine, reducing its performance. Inspect the air filter and clean or replace it if it's dirty. A clean air filter ensures that the engine receives an adequate supply of clean air during operation.
Storage Location
Selecting the right storage location is vital for the long - term preservation of your 15kW diesel generator.


- Dry and Ventilated Space: The storage area should be dry to prevent rust and corrosion. Moisture can cause significant damage to the generator's components, especially the metal parts. A well - ventilated space is also essential to prevent the buildup of fumes and vapors. Avoid storing the generator in a closed, unventilated area, as this can pose a safety hazard.
- Temperature - Controlled Environment: Extreme temperatures can affect the performance and longevity of your generator. Try to store the generator in an environment where the temperature remains relatively stable. Avoid storing it in areas that are subject to extreme heat or cold, as this can cause the engine oil to thicken or thin out, and can also damage the battery.
- Safe from Physical Damage: Choose a location where the generator will be safe from accidental bumps, scratches, and other forms of physical damage. You can use a storage shed or a garage to protect the generator from the elements and potential damage.
Storage Procedures
Once you've completed the pre - storage preparation and selected the storage location, it's time to store the generator properly.
- Cover the Generator: Use a high - quality generator cover to protect it from dust, dirt, and moisture. The cover should fit snugly over the generator to ensure maximum protection. Make sure that the cover is breathable to prevent condensation from forming inside.
- Elevate the Generator: Placing the generator on a raised platform or pallet can help prevent it from sitting in water if there is any flooding in the storage area. This also helps to improve ventilation around the generator.
- Regular Checks: Even when the generator is in storage, it's important to perform regular checks. Every few weeks, inspect the generator for any signs of damage, leaks, or corrosion. If you notice any issues, address them immediately.
Recommissioning the Generator
When the off - season is over and you're ready to use the generator again, there are several steps you need to take to ensure that it operates safely and efficiently.
- Reconnect the Battery: If you disconnected the battery during storage, reconnect it and check the voltage. Make sure that the battery is fully charged before starting the generator.
- Check the Fluids: Inspect the engine oil, coolant, and fuel levels again. If you drained the fuel tank, refill it with fresh diesel fuel. If you used a fuel stabilizer, make sure to run the generator for a few minutes to circulate the treated fuel through the system.
- Inspect the Air Filter and Other Components: Check the air filter to ensure that it's still clean and in good condition. Also, inspect other components such as the spark plugs, belts, and hoses for any signs of wear or damage. Replace any worn - out parts as needed.
- Start the Generator: Once you've completed all the checks, start the generator and let it run for a few minutes to warm up. Monitor the generator for any unusual noises, vibrations, or other issues. If everything seems to be working fine, you're ready to use the generator.
