Liquid cooled energy storage cabinet 261kWh system composition

Core system	Role	Function
Battery system	Energy Core	The mainstream adopts lithium iron phosphate (LFP) cells (such as 280Ah/314Ah), and they are connected in series and parallel to form a battery pack with an approximately 800V DC high voltage.
Battery Management System	Battery Manager	Responsible for monitoring the voltage and temperature of each battery cell, conducting SOC estimation, balancing and fault protection (secondary architecture: BMU + BCU).
Power Converters for Energy Storage	energy converter	Convert the direct current of the battery into 400V alternating current, and then feed it into the power grid or supply it to the load. It supports both charging and discharging in both directions.
EMS (Energy Management System)	Brain	Based on the peak-valley electricity pricing, formulate charging and discharging strategies (to peak-shave and valley-fill) and achieve local as well as remote monitoring.
Thermal management system	Life insurance guarantee	High-end cabinets in the industrial and commercial sector mostly adopt liquid cooling (instead of air cooling). Through the contact between the cooling plate and the battery cells, the temperature difference between the battery cells is controlled within 3-5℃, significantly extending the lifespan.
Fire extinguishing system	Safety baseline	Standard configuration includes “detection + fire suppression”. Usually, it integrates temperature and smoke sensors. It uses perfluorohexane or heptafluoropropane as the fire suppression medium. Some high-end cabinets are equipped with PACK-level precise fire suppression.
High Voltage Box	Direct current hub	The integrated DC fuse, contactor and pre-charging circuit serve as the “safety switch” between the battery cluster and the PCS.
Cabinet structure	Outdoor protective cover	The sheet metal cabinets, typically with an IP54 or IP55 protection rating, are designed with dust-proof, water-proof, corrosion-resistant and explosion-proof features.

Why choose ZZLYSUN 125kw/261kwh storage battery cabinet?
