Project News: 522kWh Liquid-cooled All-in-One High-voltage Commercial & Industrial Energy Storage System Successfully Commissioned in Jiangmen, Guangdong
Recently, the 522kWh liquid-cooled all-in-one high-voltage commercial & industrial energy storage project, independently developed, supplied and supported with on-site technical services by Dongguan Xinrui New Energy Technology Co., Ltd., has completed full-process commissioning in Jiangmen, Guangdong. All performance indicators meet standards, and the system is officially connected to the grid and put into operation. This marks another regional benchmark project delivered by Xinrui Energy in the field of high-voltage liquid-cooled commercial & industrial energy storage, providing a stable and reliable "Xinrui Solution" for enterprise-side energy storage and green low-carbon transformation in Jiangmen.
The project adopts a 522kWh liquid-cooled all-in-one high-voltage energy storage system. The single unit has a rated energy of 522.496kWh and a rated voltage of 832V, integrating battery clusters, BMS, PCS, liquid-cooled temperature control, perfluorohexanone fire protection, intelligent power distribution and communication monitoring in one cabinet. It achieves plug-and-play, rapid deployment, safe and stable operation, and long service life.
Targeting local commercial and industrial users in Jiangmen, the project mainly delivers:
Peak shaving and valley filling, as well as peak-valley arbitrage to effectively reduce corporate electricity costs
Emergency backup power and load regulation to ensure uninterrupted production and safer equipment
Green energy consumption and demand management to support low-carbon compliance and energy efficiency upgrading of enterprises
The 522kWh liquid-cooled all-in-one cabinet applied in this project guarantees stable project operation with its advantages of high integration, high safety and high efficiency:
832V high-voltage system with a voltage range of 728–949VDC, delivering higher system efficiency and lower line loss, suitable for high-voltage grid connection scenarios in commercial and industrial fields.
Professional liquid-cooled heat dissipation with 50% ethylene glycol aqueous solution coolant and 5.0kW cooling capacity. Small cell temperature difference, cycle life >6000 cycles, 5-year official warranty for more secured long-term benefits.
Modular design with a simple structure, easy for transportation and installation, greatly shortening construction period and reducing infrastructure cost, realizing true plug-and-play.
IP54 outdoor protection, stable operation in a wide temperature range of -30℃～55℃. Equipped with perfluorohexanone fire suppression system, multiple electrical protections and BMS active balancing for high reliability.
Supports CAN2.0 / RS485 communication, compatible with EMS energy management system to realize remote monitoring, data collection and charge-discharge strategy optimization.
The successful commissioning of the Jiangmen project demonstrates the comprehensive strength of Xinrui New Energy in product development, delivery capability and service quality:
It provides a replicable, fast-implementation and high-yield energy storage model for factories, parks and commercial & industrial users in Jiangmen.
It improves the safety, stability and service life of energy storage systems through liquid-cooled + high-voltage integrated technology.
It helps enterprises reduce costs, improve efficiency, cut carbon emissions and enhance power supply reliability, responding to the national "Dual Carbon" goal and the construction of a new power system.
The technical team of Xinrui New Energy was stationed on site throughout the process, providing full support including equipment installation guidance, system joint debugging, performance verification and grid connection acceptance, ensuring the project was delivered on schedule, with qualified quality and safe operation, and winning high recognition from the customer.
