With the continuous rise of diversified industrial production and refined emergency power supply needs, power generation equipment that combines flexibility and stability has become the focus of the market. Recently, a number of single-phase and three-phase equal-power diesel generator sets have been intensively launched on the market. Their core advantage of flexibly switching between single-phase and three-phase output while maintaining constant power has successfully covered multiple scenarios such as industrial production, commercial emergency response, and outdoor operations. It provides an integrated power supply solution for users with different voltage requirements and is expected to reshape the market pattern of small and medium-power diesel generator equipment.
The core breakthrough of single-phase and three-phase equal-power diesel generator sets lies in solving the industry pain point of "mismatch between single-phase and three-phase power" of traditional generator sets. Reporters learned from market research that traditional generator sets often have the problem that the single-phase output power is lower than the three-phase output, which limits the load when users switch power supply modes and cannot fully utilize the equipment power. The new-generation products, by optimizing the power structure and electronic control system, have achieved equal output power between 230V single-phase and 400V three-phase. Taking the 7kW model as an example, the three-phase mode can drive three 2.2kW motors, and the single-phase mode can also stably support high-power electrical appliances such as household air conditioners and water heaters, truly realizing the flexible adaptability of "one machine for two purposes". It is worth noting that wind-water integrated diesel generator sets within 100kW can also achieve equal-power output. Such models can achieve single-phase and three-phase equal-power switching function by customizing special motors, and are equipped with a single-phase and three-phase rotary button, allowing users to complete the power supply mode conversion without complicated operations, further improving the convenience of the equipment.
In terms of technological upgrading, such products generally integrate three core highlights: mute design, intelligent control and environmental protection technology. Taking the 15kW model as an example, by optimizing the exhaust system and body structure, the operating noise is significantly lower than that of traditional models, which can meet the needs of noise-sensitive scenarios such as medical institutions and residential communities; the equipped AVR automatic voltage regulation system ensures minimal voltage fluctuation, which can provide stable power supply for sensitive loads such as precision instruments and monitoring equipment; some high-end models are also equipped with remote monitoring functions, allowing users to grasp more than 200 operating parameters in real time, and the fault diagnosis response time is shortened to within 5 minutes, greatly reducing operation and maintenance costs. The 100kW and below wind-water integrated equal-power models, on the basis of retaining the high-efficiency heat dissipation advantage of wind-water integration, further enhance the power supply stability and switching reliability through the optimized design of customized motors.
From the perspective of market application, the applicable scenarios of single-phase and three-phase equal-power diesel generator sets have achieved full-dimensional coverage. In the industrial field, its stable three-phase output can meet the continuous operation needs of small workshop equipment; in the agricultural scenario, the two-cylinder power design ensures the reliability of irrigation equipment for long-term work; construction sites can adapt to different types of construction machinery by virtue of the flexible switching capability between single-phase and three-phase; in commercial buildings and residential communities, the mute feature and emergency power supply stability make it the preferred solution for backup power supply. Especially in scenarios without municipal power coverage such as remote area communication base stations and outdoor projects, its advantages of high efficiency, energy saving and convenient deployment are more prominent, which can effectively solve the "last mile" problem of power supply.
Industry analysts pointed out that with the advancement of the national "dual carbon" goal and the stricter regulation of emergency power supplies, low-emission, high-efficiency intelligent diesel generator sets have become the mainstream of the industry's development. Through technological innovation, single-phase and three-phase equal-power models have realized "one machine with multiple functions", which not only meets the current core demand of the market for flexible power supply, but also conforms to the development trend of environmental protection and intelligence. Data show that the market size of China's diesel generator sets reached about 18 billion yuan in 2025, and is expected to grow to 26 billion yuan by 2030. Among them, the proportion of mid-to-high-end products with multi-voltage adaptation and intelligent control functions will continue to increase.
Enterprises in the industry generally stated that they will continue to increase investment in technological research and development to further optimize the fuel efficiency and extreme environment adaptability of products. In the future, with the integrated application of technologies such as hydrogen fuel compatibility and new energy hybrid power supply, single-phase and three-phase equal-power diesel generator sets are expected to play a more important supporting role in the energy transition process, providing more efficient, green and reliable power guarantee solutions for various industries.
