User demand for cost-saving power supply
Reduce fuel consumption: Increase solar energy can significantly reduce diesel consumption, thereby reducing diesel transportation costs and operation and maintenance costs of diesel units; Stable power supply: choose solar power as the main power supply, battery packs and diesel generator sets as supplementary power supply system The intelligent control of the power grid control system can provide users with a stable power supply, reducing the daily operation and maintenance and management of the system.
Cost saving power supply solution
The entire microgrid power supply system is composed of solar power (photovoltaic power generation) as the main power supply, battery packs as temporary energy mediation power supplies, and diesel generator sets as backup power supplies. The system efficiently uses the power generated by solar energy to power the electricity facilities in the building. Diesel generator sets are generally used at night or rainy days.

Technical characteristics of stable power supply in microgrid
The system makes full use of solar power, and diesel generators form an auxiliary power supply, which can greatly reduce diesel consumption and maintenance costs of generator sets (including diesel transportation, storage, safety, equipment maintenance, maintenance, etc.).
02Fast switching technology
Seamless switching: The microgrid power supply system can operate on-grid or off-grid (island), and can seamlessly switch between on-grid and off-grid operating modes.
03Stability control technology
The micro-grid system solution is suitable for areas where the power grid often fails or the power quality is not high. The battery energy storage system supported by the microgrid can not only solve the problems of distributed power and sudden load changes that plague the development and application of new energy power supply, but also improve the stability of the connection of renewable energy power generation systems.
04Intelligent centralized control technology
The microgrid system has a built-in microgrid controller, which contains professional logic control program packages, to realize real-time mode control of the microgrid system, real-time dynamic adjustment of power supply and load, and to ensure the safe and stable operation of the microgrid system.
05Remote management technology
Through the monitoring subsystem and energy management subsystem of the microgrid, remote real-time monitoring, data analysis, and system maintenance of the microgrid system can be achieved.
06Efficient construction process
All products can be modularized and productized, and the construction is simple and fast, which can achieve the goal of power supply in a short time. Later expansion is convenient, and maintenance cost is low.
