Yuchai Generator Set – How to Select from 30kW to 2200kW (40kVA to 2750kVA)

Part 1: Accurate Power Calculation

The first and most critical step is to calculate your actual power demand. Too small – the unit won't start your equipment; too large – you waste money on both the unit and fuel consumption for years.

Three-step method:

1. List all equipment that may run simultaneously and record their rated power (kW)

2. Consider starting surge: motor-driven equipment draws 3-7 times its rated current during startup – this peak load cannot be ignored

3. Distinguish between Prime Power (continuous operation) and Standby Power (emergency use only)

Multiply your total load by a safety factor of 1.2 to 1.5 to leave room for future expansion. For a 30kW total load, consider a 37.5-45kVA unit.

Part 2: Match Power to Application Scenarios

Yuchai Generator Sets cover the full spectrum from 30kW to 2200kW. Different scenarios require different power ranges:

Part 3: Silent Type vs. Open Frame

Both configurations have their strengths. The choice depends on your installation site and budget:

Selection Tip:

• Residential areas, hospitals, schools → Silent Type

• Budget-limited with dedicated engine room → Open Frame

• Frequent relocation → Trailer-Mounted Silent Type

Part 4: Why Yuchai – Brand Strength
