How to Repair Overloaded Diesel Generators?

If the generator load is too large, it means that the generator power exceeds the limit. This means that there are too many electrical appliances or equipment connected to the generator, and the total power of the connected equipment may exceed the power of the generator. If the power limit is exceeded, your generator will not work at its best. If a malfunction occurs, the generator will automatically shut down. But if a circuit breaker is not installed, you may notice signs of generator overload.

Today, Dingbo Power will tell you how to repair overloaded generators!

Step 1: Turn off the generator.

If your generator has a circuit breaker, it will automatically close when an excessive load is detected. Another scenario is that if you find the generator still running, you should immediately turn it off. You should cool down the generator before further inspection.

Step 2: Cut off all connected electrical appliances.

After turning off the generator overload, any electrical equipment connected to it can be disconnected. Remember, overloading is caused by exceeding the recommended power limit of the generator! Removing all connected devices will help you complete the following steps.

Step 3: Identify the cause.

The next step in dealing with generator overload is to determine if it is actually overloaded. Determine if your generator is experiencing overload issues.

Firstly, you need to check the upper limit of the generator power. If your generator itself does not specify this point, you can find the necessary information in the user manual. Understanding this limitation is not only crucial for repairing overloading, but also helps prevent future overloading.

The next step is to determine if the device you are connected to exceeds the load capacity of the generator. To achieve this, it is necessary to consider the power of various devices. This means that both operating and starting power must be considered.

When starting, a device or appliance with higher power is required, which is called the starting wattage. This situation may differ from the power required to maintain the power supply. Basically, you need to ensure that the wattage of the connected device does not exceed the total power of the generator.

If you find that your equipment has indeed exceeded the specified load capacity, your generator will become overloaded. If your device does not exceed the power limit, there may be different issues that need to be resolved.

Step 4: Restart the engine.

After completing the above steps, you can restart the engine. When the generator restarts, it is important for the electrical equipment to remain disconnected. The instructions for restarting the generator vary by brand and model.

In general, it is necessary to press and hold the generator reset or power button for a few seconds to restart the generator. If an overload indicator is installed on the generator, it should be immediately turned off. In addition, the previously discussed signals should also be stopped.

Step 5: Reconnect the electrical appliances.

Since the generator has resumed operation, you can reconnect the electrical appliances. When performing this operation, it is important not to exceed the specified load capacity of the diesel generator. Ultimately, this is the primary cause of overloading.

When you reconnect the electrical appliances, considering this wattage limit, your generator should be in optimal condition again. If the signs persist, it indicates that the limit is still being exceeded. You can try repeating this process and use fewer appliances.

If you have completed this process and these signs still exist, it may mean that your generator has been overloaded. If that's the case, you should seek qualified experts to evaluate your generator and identify the root cause of the problem.
