JinkoSolar successfully deployed a 250kW/645kWh liquid-cooled microgrid energy storage system for a livestock farm in a remote area of the Middle East. By integrating photovoltaic power generation, diesel generators, and lithium battery energy storage technology, the daily operating time of diesel generators was reduced from 24 hours to just 1.5 hours, with a diesel consumption reduction of 93%. The system provides over 300 days of clean energy supply annually. This project aims to address the energy challenges in off-grid areas and promote efficient, low-carbon power supply solutions in remote settings.
The project site, located in a remote area without access to the public grid, had long relied on diesel generators for power. This led to high costs, significant pollution, and unstable electricity supply. To tackle these challenges, JinkoSolar adopted an AC-coupled microgrid solution, deploying a 645kWh SunGiga energy storage cabinet that works in tandem with a 180kW photovoltaic system and diesel generators. The energy storage system employs intelligent dispatch strategies to prioritize the use of solar power, activating the diesel backup only when the battery charge is insufficient. This approach optimizes energy use dynamically, reducing diesel generator operating time by 93% and significantly lowering annual operating costs. With a system design life of over 10 years, power supply stability has been greatly enhanced, providing a reliable energy solution for production activities.
At the core of the system is the highly integrated SunGiga energy storage cabinet, which combines liquid cooling temperature control, multi-level safety protection, and intelligent energy management technologies. The liquid cooling system, with its precise thermal management logic, maintains a cell temperature difference of less than 2°C. Coupled with its low power consumption design of only 4kW, this significantly extends battery life and improves system performance. The fire protection system features aerosol fire extinguishers and temperature/smoke detectors, enabling rapid response to thermal runaway risks. The Power Conversion System (PCS) is equipped with a 250kW inverter that supports seamless switching between grid-connected and grid-forming modes, ensuring continuous power supply to the load.
