Its mobile and portable design adapts to frequent site relocation, and the stable power output ensures the normal operation of construction equipment and improves construction efficiency.

3.3 Outdoor Field Operation Power Supply

It is perfectly applicable for field exploration, geological survey, outdoor drone operation, forest protection and field rescue work. In remote areas without municipal power grid coverage, the unit can provide long-term stable mobile power support for field equipment, solving the power shortage problem of outdoor operation teams. The water-cooled heat dissipation structure ensures stable operation in high-temperature field environments.

3.4 Industrial and Special Scenario Power Supply

It can be used as standby power for small factories, processing workshops, cold storage and breeding farms. For production and breeding equipment that cannot be powered off for a long time, the unit can quickly switch to supply power to prevent product loss and breeding casualties caused by power outages. In addition, it is also suitable for emergency power supply of communication base stations, monitoring rooms and small power distribution rooms, providing reliable power guarantee for basic equipment operation.

4. Core Purposes

The core purpose of the Yuchai YC4V45Z-D20 24kW/30kVA diesel generator set is to provide stable emergency standby power and reliable temporary mobile power for various scenarios, solve the power supply problems of grid power failure and off-grid operation, and ensure the continuous and safe operation of electrical equipment. It is a core supporting equipment for civilian life, industrial production and engineering construction power guarantee.

First of all, it undertakes the emergency power guarantee function. As a mainstream standby diesel generator set, it can realize seamless power switching after municipal power failure, maintain the continuous operation of key equipment, and avoid safety risks and economic losses caused by sudden power outages. Its 24kW prime power and 26.4kW standby power can fully cover the load demand of small and medium-sized key electrical equipment, meeting the daily standby power demand of most civilian and small industrial scenarios.

Secondly, it provides stable off-grid mobile power support. In outdoor field operations, remote construction and other scenarios without grid power coverage, the unit acts as an independent power generation system to provide continuous 50Hz stable frequency and 380V three-phase power supply for construction equipment, detection instruments and living electrical equipment, solving the power bottleneck of off-grid operation.

In addition, the low fuel consumption design of 8.1L/H full-load operation makes it realize low-cost continuous power generation. Compared with similar generator sets, it can effectively reduce the daily operating fuel cost, with higher economic benefit in long-term standby and frequent power generation scenarios. At the same time, the high-protection and high-insulation design reduces equipment failure rate and later maintenance costs, realizing long-term stable and low-cost power supply.

Finally, as a high-cost-performance Yuchai diesel generator, it fills the market gap of small and medium-power power generation equipment, meeting the customized power demand of small enterprises, individual industrial and commercial households, and engineering teams, and is one of the most widely used general-purpose power generation equipment in the field of small industrial power supply.
