1. We recommend that you select an ELECPRIME Cummins diesel generator based on your maximum power requirement.
If you will be using it continuously as your primary power source, we recommend choosing a slightly larger generator set, typically 30% higher than your maximum power requirement.
If you will be using it intermittently or periodically as a backup power source, you can choose a Cummins generator set with the same power rating as your maximum power requirement.
2. If you will be using the generator in harsh conditions such as high altitude, high temperature, humid environments, or extreme cold, we recommend purchasing a generator set with a slightly higher power rating, typically 50% higher than your maximum power requirement.
3. We recommend that you choose the appropriate power rating based on your actual usage scenario. There is no need to choose an oversized generator set.
If you have any questions about power selection, please feel free to contact us.

Our Cummins generator sets offer both ELECPRIME Alternators and STAMFORD Alternators for you to choose from.
As a world-leading brand, the quality and stability of Stamford alternators are undeniable.
ELECPRIME Alternators also utilize Stamford technology, and their quality and stability are among the best in China, but at a lower price than Stamford alternators.
If your budget allows, we can configure your generator set with a Stamford alternator; however, if you prioritize cost-effectiveness, we recommend the ELECPRIME Alternator.

1. Regularly check the engine oil level to ensure it is within the normal range. The engine oil and oil filter should typically be replaced every 400-500 hours of generator operation.
2. Regularly check the air filter; if it is dirty, clean or replace it.
3. Regularly check the coolant level; if it is below the normal range, add coolant as needed.
4. Regularly check the fuel lines, oil lines, and connections of all engine components for leaks.
If you use the generator as a backup power source and do not use it frequently, we recommend starting the generator once a month for approximately 30 minutes and checking all components to extend the generator’s lifespan.

Generally, you can determine the need for maintenance based on the following:
1. Operating time: If the generator set has been running for 400-500 hours (less than 6 months) or 6 months (less than 500 hours), the engine oil, oil filter, and fuel filter need to be replaced.
2. If you notice leakage, cloudiness, or severe discoloration of the engine oil and coolant, you need to replenish or replace them.
3. If you notice abnormal vibration, unusual noises, or overheating during generator operation, you need to shut down the unit for inspection and maintenance.
4. If you are using the Cummins generator set in harsh environments, the maintenance interval should be shortened accordingly.

We can adjust the output voltage of the generator set according to your needs, including 220V, 230V, 380V, 400V, 440V, etc.
We can also adjust it for single-phase or three-phase operation as required.
We will adjust the voltage after production is complete and confirm it with you before shipment.
The output frequency of Cummins generator sets is 50Hz (1500 rpm) or 60Hz (1800 rpm), which can be adjusted according to your usage requirements

Our Cummins generator sets are 100% tested before leaving the factory.
We can also add various accessories according to your needs, ensuring that you can use them directly upon receipt without requiring any special training.
You simply need to press the start button on the control system, and the generator set will begin to operate.

Yes, generator sets require sufficient space during operation to ensure stable performance.
1. Avoid installing them in confined indoor spaces; good ventilation and heat dissipation are crucial for the efficient operation of the generator.
2. Install the generator on a flat and firm surface. Generators produce vibrations during operation, and uneven or soft ground can lead to abnormal operation or tilting of the generator set.
3. Ensure there is at least 1 meter of space on both sides of the generator set for easy inspection, maintenance, and repair.
4. For long-term outdoor use, it is recommended to install a canopy above the generator to protect it from rain and avoid prolonged exposure to direct sunlight.

Yes, we manufacture mobile generator sets.
We can mount Cummins generator sets onto wheeled frames and equip them with soundproof enclosures and fuel tanks.
Our mobile Cummins generator sets have a power output of less than 500kW.
If you require a generator set with a power output exceeding 500kW, we recommend fixing it to the ground to prevent excessive vibration from affecting its operation.

Yes, during the long-term use of a generator set, various components will experience wear and tear, affecting the output power.
Regular maintenance can effectively reduce component wear and slow down the rate of power degradation.
Avoid prolonged operation at low load, operating the generator set at low load for extended periods will lead to increased carbon buildup and wear, thus affecting the generator set’s output power.

1. Before storing your Cummins generator set, you need to replace the engine oil and oil filter to prevent the old oil from accumulating impurities and solidifying due to long-term storage.
2. Before storage, it is recommended that you disconnect the battery from the generator set and charge the battery regularly.
3. The storage location for the generator should be free from moisture and direct sunlight.
4. If long-term storage is required, it is recommended that you install a protective cover for your Cummins generator set.
It is recommended that you start the generator set at least once a month, and each start-up should last for at least 30 minutes.

Yes, the control system we configure for Cummins generator sets is capable of recording various data during equipment operation, including load, voltage, frequency, oil temperature, and oil pressure.
Sensors are also installed on critical components of the generator set.
In the event of a malfunction, the control system will promptly issue an alarm through sound and indicator lights, prompting the operator to immediately shut down the unit for inspection to prevent further damage.

Yes, we have professional Cummins technical engineers to provide you with all the assistance you need.
When you encounter problems such as failure to start, unstable frequency, unstable voltage, insufficient power, generator overheating, excessive vibration, or insufficient oil pressure, we will help you resolve the issues immediately to ensure the equipment operates normally.

1. If used in a dusty environment, the generator set needs to be protected against dust.
2. If used in a humid environment, the generator set needs to be protected against water and rust.
3. If used in a high-temperature environment, the generator set needs to be filled with high-quality coolant and placed in a well-ventilated location.
4. If used in a high-altitude environment, the generator set may experience power loss due to thin air. A customized fuel injection system and air filtration system may be needed to maintain optimal performance.
5. Alternatively, you can purchase a generator with a slightly higher power rating to meet your needs.

Frequent starting and stopping of the generator over extended periods can lead to excessively low oil temperatures, resulting in insufficient lubrication, severe wear of engine components, and incomplete combustion of fuel, which generates a large amount of carbon deposits.
Frequent, high instantaneous current surges can also easily cause starter motor failure, reducing the lifespan of the generator set.
It is recommended that you minimize unnecessary starts and stops and rationally allocate the generator set’s operating time.
