How To Store A Diesel Engine Generator Long-Term?

Long-term storage of diesel generators requires attention to detail and consistent care. 

Proper storage preserves the generator’s performance and prevents costly repairs. 

This guide explores top tips for storing diesel generators to keep them in optimal condition, even during prolonged periods of inactivity.

Why Proper Diesel Generator Storage Matters

Storing a diesel generator properly can be critical for its performance and durability. 

Improper storage can lead to problems such as:

• Corrosion: Moisture can cause metal parts to corrode, reducing efficiency.

• Fuel Degradation: Diesel fuel can degrade over time, leading to engine clogging.

• Battery Drain: Unattended batteries can drain and even corrode, complicating future start-ups.

Following the best storage practices will help extend your generator’s lifespan, prevent costly repairs, and improve reliability when you need it most.

Preparing Your Diesel Generator for Long-Term Storage

Before storing your generator, it’s essential to complete several key preparation steps. 

A careful preparation process reduces the chance of wear and tear while in storage.

Steps to Prepare a Diesel Generator for Storage:

• Clean the Generator: Wipe down the generator to remove dirt, dust, and grime that could cause corrosion.

• Inspect for Damage: Check for any signs of wear or damage and address these issues before storage.

• Disconnect the Battery: This helps prevent drainage and potential battery damage.

• Secure Electrical Connections: Ensure that all connections are secure to avoid moisture exposure.

Following these steps will help prevent common issues, ensuring a smooth start-up once your generator is back in use.

Fuel Management During Long-Term Diesel Generator Storage

One of the most important steps in storing a diesel generator is fuel management. 

Without proper care, fuel can degrade and clog the system.

How to Manage Fuel for Stored Diesel Generators:

• Add a Fuel Stabilizer: Diesel fuel degrades over time, so adding a stabilizer will help maintain its quality and prevent clogging.

• Consider Fuel Draining or Refilling: If you’re storing the generator for a very long period, consider draining the fuel. Alternatively, refilling the tank reduces air exposure and minimizes the chance of moisture buildup.

These measures protect the fuel system, ensuring a reliable restart after storage.

Battery Maintenance for Stored Diesel Generators

Diesel generator batteries require special attention during storage. 

Without proper maintenance, they may drain or even corrode.

Tips for Diesel Generator Battery Storage:

• Disconnect the Battery: Always disconnect the battery cables to prevent power drainage.

• Store in a Dry Location: Batteries should be stored in a dry, temperature-controlled environment.

• Check Battery Charge Periodically: Recharge the battery every few months to ensure it’s ready to power up your generator.

By following these practices, you can avoid unexpected battery failures and ensure reliable operation post-storage.

Protection Against Moisture and Corrosion

Moisture is one of the biggest enemies of stored diesel generators, leading to corrosion that affects performance.

How to Protect Diesel Generators from Moisture and Corrosion:

• Use a Protective Cover: Use a high-quality, breathable cover to keep dust and moisture out.

• Store Indoors if Possible: If indoor storage is not available, use a protective tent or enclosure outdoors.

• Apply a Corrosion Inhibitor: Corrosion inhibitors provide an added layer of protection to metal parts.

These precautions will help preserve the generator’s components, reducing the risk of costly repairs due to moisture damage.

Routine Inspections and Maintenance During Storage

Even during long-term storage, periodic inspections help keep the generator in top condition and ensure it will be ready when needed.

What to Inspect on Stored Diesel Generators:

• Fuel and Oil Levels: Check the fuel and oil levels and top them up if necessary.

• Battery Health: Ensure that the battery is holding a charge.

• Filters and Belts: Look for wear or damage on filters and belts.

Regular inspections can identify potential problems before they worsen, saving time and money in the long run.

Restarting Your Diesel Generator After Long-Term Storage

Bringing a diesel generator back online after long-term storage requires specific steps to avoid complications and ensure a smooth start.

Steps to Restart a Diesel Generator After Storage:

• Reconnect the Battery: Reinstall the battery, checking connections to make sure they’re secure.

• Check Fluid Levels: Inspect all fluid levels, including oil, fuel, and coolant.

• Prime the Fuel System: Priming the fuel system removes any air pockets, ensuring efficient combustion.

These steps help your generator start smoothly, minimizing wear and tear after a prolonged rest period.

Common Mistakes to Avoid in Diesel Generator Storage

Avoiding common mistakes can significantly improve the lifespan and performance of your diesel generator.

Common Storage Mistakes:

• Neglecting Fuel Stabilization: Unstabilized fuel can clog the system and cause start-up issues.

• Failing to Disconnect the Battery: This often results in unnecessary battery drainage.

• Inadequate Moisture Protection: Exposure to moisture can corrode key components, leading to early failure.

By avoiding these mistakes, you ensure your generator remains in optimal condition.

Frequently Asked Questions About Diesel Generator Storage

Q: How long can you store a diesel generator without use?

Diesel generators can be stored for several months with proper preparation, although periodic maintenance is recommended.

Q: Should I start my generator during long-term storage?

Starting your generator periodically can keep parts lubricated, but be sure to check fuel levels and battery charge if you do.

Conclusion

Proper diesel generator storage is essential for preserving performance, reducing maintenance costs, and extending lifespan. 

Following these top storage tips, you’ll ensure that your generator remains reliable and ready for use whenever needed.
