New product release SNEC 2024 energy technology industrial and commercial energy storage full liquid cooling machine was officially unveiled


With the continuous adjustment of the global energy structure and the rapid development of renewable energy, energy storage technology has become one of the key technologies to promote energy transformation. During the 17th Shanghai International Photovoltaic Exhibition in SNEC2024, ZNTECH held a new product conference, and its industrial and commercial energy storage fully liquid cooled all-in-one machine was officially unveiled to innovate multiple product matrix to meet market demand in an all-round way all-round.

Industrial and commercial energy storage is booming, but it also faces many challenges such as site fragmentation, high operation and maintenance management costs, low intelligence and system security risks. In this fierce competition, only with core competitiveness, in order to stand out.

In SNEC 2024 exhibition, ZNTECH with a new industrial and commercial energy storage fully liquid cooled all-in-one machine "Enerwow-M261" shining debut, which is widely used in energy storage power stations, industrial parks, microgrids, building buildings, communication base stations and other energy use environment. At the SNEC2024 exhibition site, many guests stopped and competed to watch.

“Enerwow-M261”is the first fully liquid-cooled integrated cabinet released by ZNTECH

“Enerwow-M261”the whole system adopts the design of "All-In-One" machine.


At the battery level, the new 314 lithium iron phosphate battery dedicated to energy storage is used, which has the characteristics of high efficiency and long life, which can greatly improve the energy density of the product.


PCS adopts full liquid cooling products independently developed by CNPE, and adopts traditional SVPWM modulation algorithm to realize four-quadrant operation function. In addition, the hardware topology adopts diode midpoint clamp three-level topology, also known as NPC multilevel topology, which has the functions of low voltage crossing, high voltage crossing and anti-island protection.


3S domain control integration is adopted in the system, integrating BMS, PCS and EMS functions, and the control circuit uses DSP+FPGA+ARM three-chip architecture, which reduces the system redundancy, avoids the communication connection problem between multiple devices, improves the system control and communication cooperation efficiency, and runs more stable.

The Enerwow-M261 system is designed with full liquid cooling.


For the battery PACK, the brazed liquid cooling bottom plate is used to achieve uniform cooling of the battery, greatly reducing the temperature difference of the system cell, and the temperature difference in a single PACK can be achieved within 2.5 ° C.


PCS uses liquid cooling for heat dissipation, greatly reducing internal volume and improving charge and discharge efficiency.


PACK and PCS share a liquid cooler in the system, and the two main heating sources of battery and PCS are controlled by liquid cooling. In addition to improving the overall efficiency, the heat dissipation method of full liquid cooling also greatly reduces the consumption of the auxiliary source system.

The "Enerwow-M261" system adopts the reliable design of three-level fire protection to ensure the safe operation of the system.


The PACK is equipped with an automatic fire extinguishing device to collect internal temperature anomalies to realize self-triggering fire extinguishing.


Secondly, the cluster level is equipped with smoke and temperature detectors, which can actively detect fire fighting anomalies in the cabinet and achieve fire extinguishing medium eruption. In addition, the top of the electric cabinet is equipped with a fire extinguishing panel to keep the converged cabinet safe and reliable.


In addition, the Converged cabinet is equipped with a DN65 water fire interface at the top, which serves as a third-level backup fire protection method.

"Enerwow-M261" system has the functions of black start, anti-reverse flow, and off-grid operation, and can realize multiple cabinets in parallel, convenient expansion; It can meet the needs of full-scene energy storage applications such as new energy grid-connection, peak regulation and frequency regulation, demand-side response, and micro-grid in one stop, helping to achieve scientific power saving, environmental protection and low-carbon development.
