How to store a 6.6kv Diesel Genset when not in use?

Jul 28, 2026

Storing a 6.6kv Diesel Genset properly when it's not in use is crucial to maintain its performance, extend its lifespan, and ensure it's ready for operation when needed. As a supplier of 6.6kv Diesel Genset, I've seen firsthand the importance of correct storage practices. In this blog, I'll share some key steps and considerations for storing a 6.6kv Diesel Genset effectively.

Pre - storage Preparation

1. Clean the Genset

Before storing the 6.6kv Diesel Genset, a thorough cleaning is essential. Dirt, debris, and oil can accumulate on the surface of the genset during operation. Use a mild detergent and water to clean the exterior. Pay special attention to the radiator, air intake, and exhaust areas. A clean genset is less likely to develop corrosion and other issues during storage.

2. Conduct a Maintenance Check

Perform a comprehensive maintenance check. This includes inspecting the engine oil level, coolant level, and fuel level. Change the engine oil and filter if it's close to or past the recommended service interval. Check the coolant for proper concentration and top it up if necessary. For the fuel system, consider using a fuel stabilizer to prevent fuel degradation over time. This helps to avoid starting problems when the genset is taken out of storage.

3. Inspect Electrical Components

Examine all electrical components, such as the alternator, battery, and wiring. Check for any signs of damage, loose connections, or corrosion. Clean the battery terminals and apply a thin layer of petroleum jelly to prevent corrosion. Ensure the battery is fully charged before storage. If possible, disconnect the battery to avoid self - discharge.

4. Lubricate Moving Parts

Lubricate all moving parts, including the engine's pistons, crankshaft, and other mechanical components. This helps to prevent rust and wear during storage. Follow the manufacturer's recommendations for the type and amount of lubricant to use.

Storage Location

1. Choose a Dry and Well - Ventilated Area

The storage location should be dry to prevent moisture from causing rust and corrosion. A well - ventilated area is also important to prevent the build - up of fumes and gases. Avoid storing the genset in areas prone to flooding or high humidity, such as basements without proper ventilation.

2. Protect from Physical Damage

The storage area should be free from potential sources of physical damage. This includes avoiding areas where heavy objects could fall on the genset or where it could be hit by moving equipment. Consider using a protective cover to shield the genset from dust, debris, and minor impacts.

3. Temperature Considerations

Extreme temperatures can have a negative impact on the genset. Avoid storing the genset in areas that are too hot or too cold. If the storage area is subject to significant temperature fluctuations, consider using insulation or a temperature - controlled environment to maintain a more stable temperature.

Storage of Fluids

1. Fuel

As mentioned earlier, use a fuel stabilizer to prevent fuel degradation. If the genset will be stored for an extended period, it may be advisable to drain the fuel tank. However, if you choose to keep the fuel in the tank, make sure it's a high - quality fuel and that the stabilizer is added in the correct proportion.

2. Engine Oil

Change the engine oil before storage to remove any contaminants that may have accumulated during operation. The fresh oil will provide better protection against rust and corrosion. Leave the oil in the engine during storage.

3. Coolant

Ensure the coolant is at the proper level and concentration. A coolant with the right antifreeze and corrosion - inhibiting properties will protect the engine's cooling system during storage.

Long - term Storage

1. Periodic Inspections

Even during storage, it's important to conduct periodic inspections. Check the genset every few months to ensure there are no signs of damage, corrosion, or leaks. Inspect the battery to make sure it's still charged. If the battery voltage drops significantly, recharge it.

2. Exercise the Genset

If the genset will be stored for a long time, it's beneficial to run it periodically. This helps to keep the engine components lubricated, prevents fuel from gelling, and ensures the electrical system remains functional. Run the genset for at least 30 minutes every three months. Follow the manufacturer's guidelines for the correct running procedure.

Post - storage Preparation

1. Re - check Fluids

Before putting the genset back into operation, re - check all fluid levels. This includes the engine oil, coolant, and fuel. If any fluid levels are low, top them up.

2. Inspect Electrical Components

Inspect the electrical components again to ensure they are in good working condition. Check the battery, alternator, and wiring for any signs of damage or corrosion that may have occurred during storage.

3. Perform a Test Run

Conduct a test run of the genset to make sure it starts and operates smoothly. Monitor the engine's performance, including the speed, temperature, and voltage output. If any issues are detected, address them before using the genset for its intended purpose.
