When deploying a 200kW generator set in a commercial facility, an Automatic Transfer Switch (ATS) is required; in the event of a mains voltage drop or power outage, the ATS seamlessly transfers the entire electrical load from the grid to the generator within 8 to 15 seconds. This rapid emergency response mechanism effectively safeguards commercial assets and ensures the safety of personnel.

Is a 300kW generator large enough for a factory?

Typically, a 300kW generator set can meet the operational needs of small and medium-sized factories; it is capable of simultaneously powering 6–8 units of equipment—such as lathes, milling machines, injection molding machines, laser cutters, industrial air filtration systems, and air compressors—while also supporting workshop lighting and automated assembly conveyor lines.
For large factories, a single 300kW generator set is usually insufficient to handle standard power loads and typically serves as a backup power source. However, if continuous operation is required, we can configure Deep Sea paralleling controllers to synchronize and operate two or more 300kW generators in parallel, thereby meeting high-load power demands.

How do I choose between a 100kW, 200kW, and 300kW generator?

You should determine the generator set’s power rating based on the current total load and future expansion plans. If the total continuous load is below 75 kW, a 100 kW generator set is the optimal choice; this capacity is typically suitable for light commercial centers or small factory workshops. If your power requirements fall within the 120–150 kW range, a 200 kW generator set is best, as it can adequately handle the demands of large inductive loads. For industrial manufacturing and large-scale infrastructure projects, a 300 kW generator set is usually required to manage the simultaneous starting and stopping of multiple pieces of heavy equipment; such units offer sufficient torque and current capacity to maintain frequency stability under heavy loads and load fluctuations.

What is the fuel consumption of a 200kW generator at 75% load?

When a 200kW generator set operates continuously at 100% full load, fuel consumption is approximately 54 to 60 liters per hour; when the load drops to 50%, consumption decreases to about 28 to 32 liters per hour.
Fuel consumption during continuous operation varies by engine brand; generally, Perkins generator sets are more fuel-efficient than Cummins models, though Cummins units are better suited for heavy-load applications.

Every 500 hours or six months, the engine oil and oil filter must be changed, the fuel filter replaced, and the air cleaner inspected; additionally, the battery requires inspection and the removal of any corrosion from the terminal connections.
Every 1,500 hours or 12 months, a comprehensive mechanical performance verification using a load bank is required, along with checks on drive belt tension and verification of the cooling system’s operational capability in high-temperature environments.

What is the difference between standby power and prime power ratings?

In accordance with the ISO 8528 international standard, the maximum operating load, operating duration, and maintenance intervals for ELECPRIME 100–300 kW generator sets are determined by their power ratings.
The prime power rating determines the generator set’s capability to serve as an independent power source; within this rated capacity, it can typically operate for unlimited hours annually. An average load factor of 70% to 80% of the rated prime power is recommended. Generally, prime power generator sets feature a 10% overload capability, allowing them to handle a load of 110% of the rated power for up to one hour during every 12 hours of continuous operation.
Generator sets with a standby power rating are designed for emergency use and cannot serve as a continuous power supply. Furthermore, standby power units do not possess overload capability; the recommended average load factor is no more than 80% of the rated power, with a maximum annual operating time of 500 hours.
