Key Features & Benefits
Modular Rack Mount Design for Easy Expansion
THS15 adopts a standard 5U rack mount battery design, which is compatible with mainstream battery cabinets and server racks. The modular structure allows users to easily expand storage capacity by connecting up to 16 battery units in parallel, meeting different energy storage requirements from residential systems to commercial applications.
Long Cycle Life with Lower Total Cost
Equipped with high-quality LiFePO4 cells, THS15 provides excellent durability and safety. Under 80% depth of discharge (DOD) conditions, the battery achieves more than 6,000 cycles with a designed service life of over 10 years, helping reduce replacement costs and improve the overall return on investment of energy storage systems.
2A Active Cell Balancing Technology
The integrated 2A active balancing function automatically balances the voltage difference between individual cells during charging and discharging. This helps reduce capacity loss caused by cell imbalance, improves battery efficiency, and extends the overall lifespan of the lithium battery system.
Intelligent BMS with Bluetooth Monitoring
THS15 is equipped with an intelligent BMS battery management system that provides multiple safety protections, including overcharge, over-discharge, overcurrent, short circuit, over-temperature, and low-temperature protection.
The built-in Bluetooth monitoring function allows users to check battery status through a mobile APP, while CAN/RS485/RS232 communication interfaces ensure smooth integration with solar inverters, EMS platforms, and energy management systems.
