50 kW / 62.5 kVA Diesel Generator
The 50 kW diesel generator set delivers 62.5 kVA prime power (82.5 kVA engine standby rating) on 50 or 60 Hz, powered by the Yuchai YC4D90Z-D21 engine and configured for light manufacturing, agri-processing, gas stations in Vietnam, Philippines, Thailand and across Southeast Asia.
4.21L high-displacement engine with strong low-end torque; cost-competitive within its power class.

Power ratings follow ISO 8528-1:2018 (Prime PRP / Standby ESP), and the fuel figures are stated at ISO 3046-1:2002 standard reference conditions. Both are confirmed unit by unit on our load bank, and the test record ships with the set. Standby figures are the engine's factory standby rating from the model spectrum table — never a computed 110% of the rated output. Noise figures are typical open-type reference values, not a guaranteed sound-power level.
All specifications subject to confirmation per order. Spectrum table is the internal reference; final data per technical agreement.
Estimated Fuel Consumption
Fuel consumption varies with load, ambient temperature, fuel quality and test conditions. Figures below are estimates at 50 Hz / 400V under standard conditions; do not read them across as 60 Hz delivery data, which is confirmed per order.
| Load | 50% | 75% | 100% | 110% (1h) |
|---|---|---|---|---|
| Fuel Consumption (L/h) | 7 | 10 | 13 | 14.7 |

Frequently Asked Questions
Background reading: how load changes liters per hour and choosing 50Hz vs 60Hz for your grid.
How much fuel does a 50 kW generator use?▼
At 100% load the 50 kW set consumes about 13 L/h (10 L/h at 75%, 7 L/h at 50%). Actual consumption depends on load profile, ambient conditions and fuel quality.
Is the 50 kW set prime or standby rated?▼
The set is rated 50 kW prime / 62.5 kVA, and the Yuchai YC4D90Z-D21 engine it ships with is rated 60 kW prime / 66 kW standby in the factory model spectrum table. Prime rating suits continuous or variable load; the standby figure is the engine's factory standby rating, not a computed 110% of rated output. Confirm the duty with your engineer before ordering.
What voltage and frequency can it run at?▼
400/230V (50Hz) / 220-480V (60Hz), selectable 50 or 60 Hz. The alternator is calibrated per order; confirm your local grid configuration. Where a model is quoted at 60 Hz, the 60 Hz rating is confirmed on the order.
Can this generator be supplied for Vietnam?▼
This model is actively supplied to Vietnam, Philippines, Thailand, Malaysia, Myanmar, Indonesia, Singapore. Import duties and documentation depend on the destination country, HS code and applicable trade agreements (for example ACFTA Form E eligibility). Confirm requirements before shipment.
What options are available (open, silent, container)?▼
Open skid, silent canopy, containerized and trailer configurations are available on request. Options affect noise level, dimensions, weight and price.
