Introduction

In today's rapidly transitioning energy structure towards clean and low-carbon, electricity has become the lifeline of production and daily life. However, in many remote areas and areas with weak power grid coverage, power outages and restrictions remain uncertain factors, frequently disrupting the operation of factory assembly lines, affecting the daily lighting of herdsmen, and restricting the economic development of islands. Although traditional diesel power generation can provide emergency response, it is accompanied by high fuel costs and pungent exhaust emissions, making the demand for energy upgrading increasingly urgent.

Based on the coupling of light storage and DC, the integrated light storage and diesel generator is meeting the dual demands of reliability and usability in the market due to its high integration, convenient installation, high photovoltaic conversion efficiency, and precise and fast energy control capabilities. It has become a solution for many new construction projects.

Current situation faced

The photovoltaic storage DC coupling solution achieves efficient collaboration between photovoltaics and energy storage through an integrated DC bus architecture, greatly improving system efficiency and response speed. This solution is particularly suitable for highly integrated application scenarios such as optical storage integrated machines, significantly reducing system costs while improving energy utilization efficiency. But there are the following issues:

Insufficient depth of equipment monitoring: The existing system lacks comprehensive monitoring of battery characteristics and diesel generators, and lacks in-depth monitoring of key parameters such as SOH, SOC, BMS, PCS, and fault information. At the same time, the data collection of the operating status and fuel efficiency of the diesel generator set is incomplete, which affects the reliability of the system.

Single economic operation strategy: In the grid connected operation mode, the energy storage system fails to fully utilize the peak valley electricity price difference to achieve intelligent charging and discharging strategies, lacking advanced functions such as demand control, dynamic expansion, and backflow prevention, resulting in the system's operational economy not being maximized.

Low remote operation and maintenance efficiency: Operating data is scattered across various subsystems, lacking a unified data center for centralized management and in-depth analysis, resulting in a lack of data support for operation and maintenance decisions and insufficient preventive maintenance capabilities.

Lack of collaborative ability: During the process of switching between parallel and off grid, relying on manual operation of diesel generators results in slow response speed and low reliability; At the same time, whether connected to or disconnected from the grid, the coordination and control of solar energy storage need to be further optimized.

Poor fuel economy: The energy storage system failed to form fuel optimization synergy with the diesel generator set, and was unable to minimize fuel consumption through intelligent power allocation during off grid operation, resulting in high operating costs.

Product List

Typical case series

A clothing factory in Myanmar has been hindered in production due to frequent power outages caused by poor stability of the power grid. Therefore, three integrated photovoltaic and diesel storage machines have been installed in parallel to ensure stable and reliable power supply. The use of Ankerui energy storage management system ensures the continuity and reliability of power supply, improves factory production efficiency, and enhances economic benefits.

The energy storage management system can not only fully utilize local solar energy resources to achieve green and low-carbon power supply, but also flexibly switch and operate off grid modes according to grid conditions, reduce electricity costs and improve operational economy through multi energy complementarity.

Conclusion

The integrated light storage and diesel solution launched by Ankerui is not only suitable for areas with insufficient power grid coverage or unstable power supply, but also for off grid areas such as islands, pastoral areas, outposts, oil fields, mines, orchards, fish ponds, etc.

From homestays on islands to settlements in pastoral areas, from remote outposts to work sheds in mining areas, the adaptation scenarios of the Acrel-2000ES energy storage cabinet energy management system are ubiquitous. It not only solves the electricity pain points in off grid and weak grid areas, but also responds to the call for energy transformation with a green and low-carbon operating mode, making the goals of reliable, economical, and clean electricity take root in every corner.
