Comprehensive Introduction to LithiumValley FLEX16 High Voltage C&I Energy Storage System
Product Positioning & Core Design Concept
LithiumValley FLEX16 is a rack-mounted high-voltage lithium iron phosphate energy storage system independently developed for global commercial and industrial energy storage application scenarios, dedicated to solving enterprises’ high electricity cost, unstable grid power supply, insufficient photovoltaic power self-consumption and emergency power backup demands. Adopting advanced modular stacked design, the standard single cabinet basic capacity is 96kWh, and users can freely connect up to 12 cabinets in parallel for capacity expansion, with the maximum total usable capacity reaching 3.08MWh, which can flexibly meet the power storage needs of small, medium and large industrial and commercial projects of different scales.
Core Technical Highlights
Different from traditional low-voltage energy storage equipment, FLEX16 innovatively applies wireless stacking connection technology, completely abandons cumbersome high-voltage cable wiring between cabinets, greatly simplifies on-site construction procedures, shortens the overall installation cycle by more than 40%, and effectively reduces hidden dangers such as wiring aging and circuit faults caused by complicated wiring in long-term operation. Equipped with built-in cell active balancing system and AI intelligent energy management system (EMS), the equipment can monitor the voltage, current and temperature of each single cell in real time 24 hours a day, automatically adjust the charging and discharging state of batteries to eliminate voltage inconsistency between cells, slow down battery capacity attenuation, maximize the overall utilization rate of the energy storage cluster, and effectively extend the cycle service life of the whole system.
Working Modes & Application Scenarios
This energy storage system supports multiple working modes including grid-connected peak shaving and valley filling, off-grid independent power supply, photovoltaic coupled energy storage, and emergency backup power. It is widely applied to industrial parks, factory workshops, office buildings, shopping malls, data centers, remote mining areas, island microgrids and other scenarios worldwide. Meanwhile, FLEX16 builds an open inverter ecological system, which adopts universal communication protocols and can be seamlessly matched with mainstream hybrid inverters on the market such as Solis, Goodwe, FoxESS, INVT and Solinteg, bringing great convenience for system integrators to configure customized light storage integrated solutions for overseas customers.

Four-Tier Progressive Comprehensive Safety Protection System
Cell-level Intrinsic Safety Protection
At the cell level, each lithium iron phosphate cell is equipped with independent overvoltage, undervoltage, overcurrent and temperature monitoring sensors. Once the single cell exceeds the safe voltage threshold or abnormal temperature rise occurs, the BMS will immediately cut off the charging and discharging loop of the corresponding cell to avoid abnormal energy accumulation inside the cell. The lithium iron phosphate material itself has excellent thermal stability, no violent combustion or explosion will occur under puncture, extrusion and overheating conditions, which is the primary guarantee of battery intrinsic safety.
Module-level Thermal Uniformity Control
At the module level, each battery module is equipped with thermal isolation partitions, uniform temperature conduction materials and smoke sensing probes. The internal temperature difference of the module is always controlled within a reasonable range to avoid local overheating caused by inconsistent heat dissipation. When the module has abnormal heat accumulation, the system will trigger early warning signals in advance and adjust the charge-discharge power to reduce the heat generation of the battery module.
Cabinet-level Fire Prevention & Emergency Protection
At the cabinet level, the whole cabinet adopts fire-resistant metal shell and flame-retardant internal wiring materials, built-in aerosol fire suppression device and independent smoke alarm system. Once open fire or dense smoke is detected inside the cabinet, the fire extinguishing device will be automatically activated to quickly put out the initial fire source and prevent the fire from spreading to the whole cabinet and adjacent equipment. In addition, the cabinet is equipped with emergency power-off buttons, high-voltage insulation monitoring modules and drainage structures to cope with accidental water inflow and high-voltage leakage risks.
System-level Cluster Interlock & Intelligent Early Warning
At the whole system level, the energy storage cluster realizes interlock protection between all cabinets. If any single cabinet fails abnormally, the system will automatically isolate the faulty cabinet without affecting the normal power supply of other equipment. The AI EMS platform continuously collects all operating data of the system, conducts big data risk analysis, pushes fault alarm information to users’ mobile terminals in real time, and supports remote parameter locking to avoid misoperation. The whole set of safety design has passed multiple international electrical safety certifications, adapting to the safety access standards of various countries and regions around the world, which can fully meet the strict safety requirements of industrial and commercial indoor energy storage stations.
