Application scenarios

Hosting servers, storage, and cooling systems, a mains power outage can cause data loss and business paralysis.

Unit selection recommendations

Selection Elements Recommendations

Power range: Common power is 1800-2000kW per unit, with the number determined by total load and redundant configuration

Redundancy configuration N+1 or 2N, depending on Tier level

Startup speed: Starts and loads within 10-15 seconds

Parallel capability: Supports 10-60 units in parallel, with load sharing and flexible parallel functions

Control System: High-precision digital speed and voltage regulation, supports integration with DCIM systems

New addition: Technology trends and upgrade considerations

Hybrid and energy storage integration: The "energy storage-first" solution of lithium battery energy storage systems + diesel power reduces diesel power generation idle time and lowers emissions.

Hydrogen backup power: For new hyperscale data centers, the feasibility of hydrogen fuel cells as zero-carbon backup power can be evaluated.

Modular prefabrication: Containerized diesel-engine modules enable rapid deployment and flexible capacity expansion.

Key Installation Points

Independent machine rooms, check the load-bearing capacity of floor slabs and floors, and consider vibration isolation

Independent intake and exhaust design for CFD heat flow simulation

The oil storage room meets fire safety standards, with a full capacity of 8-24 hours, and dual oil sources are recommended

Commissioned in conjunction with UPS and ATS systems to complete dummy load testing and parallel debugging

Supplement: Transportation and lifting

Large units require dedicated lifting ports and transport channels, with routes and unloading platforms planned in advance

Container-type modules can be loaded and unloaded directly using dock cranes or truck-mounted cranes

Possible Issues

Problem, cause, solution

Cannot carry load after startup; mismatch between control system and load switching logic; joint debugging with ATS is completed before leaving the factory

Uneven power distribution in parallel machines, parallel controller parameters not calibrated, power sharing commissioning conducted on site

Insufficient heat dissipation to reduce power Ventilation area or high duct resistance Heat load calculation before construction

Fuel deterioration and clogging of fuel circuits Long-term standby unused, diesel oxidation gels Establish regular oil inspection and replacement systems, and install oil-water separators

Environmental compliance risk: Emissions do not meet local regulations (such as Stage V). Confirm emission levels when selecting and install exhaust after-treatment devices

New environmental and certification requirements

Exports to the EU must meet Stage V emission standards, while North America requires EPA Tier 4 standards

Noise must be controlled within local environmental limits (typically≤ 65dB(A))

Fire safety acceptance requires a third-party inspection report for unit fire linkage
