Both Mitsubishi and Cummins generators are world-renowned brands, but they differ significantly in their technological applications. For the same power output, Mitsubishi engines have a larger displacement than Cummins engines, meaning higher torque at low speeds. Mitsubishi generators mostly use a fully mechanical control system, while Cummins’ electronic control system is highly mature. This combination of high-power engine and mechanical structure design results in a longer lifespan for Mitsubishi generator sets compared to Cummins generator sets.

Typically, after a power outage, data centers require generator sets to start and connect to the load within 8-10 seconds. This places high demands on the generator sets’ transient response and sudden load capacity.
Mitsubishi generator sets are renowned for their superior transient response and voltage stability. All Mitsubishi generators are equipped with their own in-house developed turbochargers, ensuring a high degree of matching and rapid start-up. This increases air intake, ensuring the generator set reaches maximum power output in a very short time.

Genuine imported Mitsubishi generator sets have a power output greater than 2000kW, while genuine Mitsubishi generator sets ranging from 500-2000kW are assembled in Shanghai, China.
Both are genuine products with global warranty. ELECPRIME sells Mitsubishi generators with a power range of 500-2000kW, all assembled in China. These alternators are typically matched with world-renowned brands such as Stanford and Leroy Somer.
If you need to purchase a Mitsubishi generator and are looking for a balance between performance and price, this is the best choice.

1. Observe the nameplate and serial number of the Mitsubishi generator set. Genuine Mitsubishi nameplates are usually made of stainless steel or high-temperature resistant aluminum alloy, and the serial number is usually engraved on the flat surface of the cylinder block near the flywheel housing.
2. The turbocharger and fuel injection pump of the generator set are manufactured by Mitsubishi. Check if the turbocharger’s nameplate is Mitsubishi branded, and check the part number of the fuel injection pump.
3. Check if the engine block of the Mitsubishi generator set has the Mitsubishi brand logo.
4. Call Mitsubishi’s official after-sales service hotline to confirm.

Typically, Mitsubishi generators can withstand a 100% load increase in a short time. When the load increases by 100% instantaneously, the voltage drop is typically within 25% and recovers within one second. Frequency fluctuations are usually within 10%, making them particularly suitable for critical locations such as data centers and hospitals.
The powerful one-step load capability of Mitsubishi generator sets stems from their large-displacement engines and fast-response turbochargers, providing ample power and torque reserves to handle the resistance caused by sudden load increases.

Yes, with a suitable cooling system, a Mitsubishi generator set can operate at 100% load for extended periods in high-temperature environments.
1. Configure a 50°C radiator with a larger heat dissipation area and a more powerful fan.
2. Increase the air intake airflow and reduce its temperature.
3. Add an air guide shroud to the exhaust port to prevent hot air from flowing back into the intake.
4. Use a high-insulation-class AC generator and a temperature rise control system.

In high-power applications such as power plants, mines, large factories, or industrial parks, multiple Mitsubishi generator sets are typically used in parallel to replace a single high-power generator set.
ELECPRIME Mitsubishi generator sets usually use DeepSea, ComAp, or SmartGen controllers for parallel operation, enabling automatic voltage synchronization and load distribution. When the load is high, the operation and load distribution among the paralleled units are very smooth, preventing single unit failure due to overload. When the load is low, one generator set can be automatically kept running while the others are shut down to prevent power loss and extend the generator set’s lifespan.

After 10,000 hours of operation, you need to inspect key components such as the cylinder head, valves, fuel injectors, and turbocharger.
At 30,000 hours, a major overhaul is required, involving complete engine disassembly to inspect and replace core worn parts such as cylinder liners, pistons, piston rings, crankshaft bearings, and connecting rod bearings. The fuel system is also inspected, and the alternator is disassembled to check for wear.
After the overhaul, the generator set is reassembled and tested to restore it to optimal condition. With proper maintenance, a Mitsubishi generator set can typically last for over 60,000 hours.

1. Change engine oil, oil filter, and diesel filter every 500 hours.
2. Change air filter and check battery and battery cables every 1000 hours.
3. Adjust valve clearance and check fuel injectors and turbocharger every 1500 hours.
4. Change coolant, clean radiator, and check starter motor and alternator operation every 3000 hours.
5. Perform a comprehensive generator set inspection every 10,000 hours.
6. Perform a major overhaul of the generator set every 30,000 hours.

1. Common alarms related to the cooling system include overheating and low coolant level.
2. Common alarms related to the lubrication system include oil pressure alarms.
3. Common alarms related to the generator set’s electrical system include failure to start or low battery voltage.
4. Common alarms related to the fuel system include unstable voltage or frequency, and unstable engine speed. When your Mitsubishi generator set experiences these malfunctions, the control system will illuminate warning lights and issue an alarm. Severe malfunctions may lead to an emergency shutdown.

ELECPRIME typically prepares easily damaged spare parts with your shipment. During the warranty period, we will send you genuine Mitsubishi spare parts free of charge and cover shipping costs. You can also purchase spare parts through Mitsubishi dealers worldwide.
You can also purchase genuine Mitsubishi spare parts from us at extremely low prices; however, you will need to bear the shipping costs. You can also ship purchased spare parts together with new orders to reduce shipping costs.

Black smoke from a Mitsubishi generator set is usually due to incomplete fuel combustion. You need to check if the generator set’s air filter is clogged, if the turbocharger is working properly, and then check the intercooler, fuel pump, and fuel injectors.
If these components are all fine, then you need to check if your Mitsubishi generator set is being overloaded. Additionally, poor-quality diesel fuel can also cause black smoke; ensure you are using high-quality diesel fuel.

Yes, Mitsubishi generator sets can use HVO fuel without any additional configuration. Compared to conventional diesel, HVO fuel can reduce carbon dioxide emissions by 90% and burns more completely. However, due to its lower energy density, using HVO as fuel will reduce the power output of Mitsubishi generator sets by about 2%, and fuel consumption will increase by about 5% under the same load. Compared to diesel, HVO fuel is ideal for long-term storage, typically lasting up to 10 years.

1. Meets North American Tier 2/Tier 3 emission standards.
2. Meets European Stage II/Stage II I/Stage IIIA emission standards. Mitsubishi generator sets are designed for the global market and meet the emission standards of the vast majority of countries and regions. For special emission requirements, emissions can be further reduced by adding a catalytic reduction system and a diesel particulate filter system.

If you order a standard Mitsubishi generator set, we usually deliver within one month.
