Off-Grid PV-DG-ESS
The PV-DG-ESS system finds extensive application in remote areas without grid coverage, for instance, providing stable power to rural communities, islands, and isolated industrial or mining sites. It’s also an ideal choice for farms and ranches, supporting irrigation, lighting, and equipment operation. Furthermore, in scenarios demanding exceptionally high power supply continuity, such as telecommunications base stations, field research outposts, and military detachments, the PV-DG-ESS system delivers reliable independent power, ensuring critical tasks proceed smoothly.
Off-Grid PV-DG-ESS Solutions
An Off-Grid Photovoltaic-Diesel Generator-Energy Storage System (PV-DG-ESS) is an independent energy solution designed for areas without reliable grid access. It integrates solar photovoltaics (PV), a diesel generator (DG), and an energy storage system (ESS). During the day, PV panels generate electricity to power loads and charge batteries. When solar power is insufficient or at night, the stored energy is used. If storage runs low, the diesel generator automatically starts as a backup to ensure continuous power supply.
This system aims to enhance energy efficiency and reduce operational costs, particularly by cutting down diesel consumption and carbon emissions. Through smart control, the PV-DG-ESS optimizes the operation of its components, providing reliable and cost-effective electricity. It offers an ideal, sustainable power solution for remote areas, farms, and other applications requiring self-sufficient power.

Off-Grid Energy Storage Solution
Project Case: 5MWH Liquid Cooling
This project is a 5 megawatt-hour (MWh) liquid-cooled battery energy storage system. It employs advanced liquid cooling technology, which, compared to traditional air-cooling methods, more efficiently and precisely manages battery temperature. This significantly enhances the battery’s charging/discharging efficiency, cycle life, and safety. The 5MWh capacity provides flexible power support to the grid, capable of peak shaving, frequency regulation, load shifting, or acting as a stabilizer for renewable energy integration, effectively mitigating the intermittency of new energy generation. This case highlights the advantages of liquid cooling technology in large-scale energy storage systems and its positive impact on power system stability and economic benefits.
