Product Features
AnengJI THS15 is a high-performance 48V 280Ah LiFePO4 battery with a total energy capacity of 14.33kWh. Designed with a standard 5U rack mount structure, this lithium battery storage solution is ideal for residential solar energy storage, backup power systems, off-grid applications, and commercial energy storage projects.
Featuring advanced lithium iron phosphate (LiFePO4) battery technology, THS15 delivers excellent safety, long cycle life, and stable performance for long-term operation. The built-in intelligent Battery Management System (BMS) provides comprehensive protection, while the integrated 2A active cell balancing technology improves battery consistency and maximizes available energy capacity.
Supporting up to 16 units connected in parallel, THS15 offers flexible scalability from household solar battery systems to larger commercial and industrial energy storage applications. It is an ideal choice for global distributors, solar installers, and energy storage system integrators looking for a reliable and expandable battery solution.
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.
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.
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.
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.
After strict compatibility testing, THS15 supports most mainstream 48V solar inverters, reducing installation complexity and improving system integration efficiency.
It can be widely used in:
THS15 has passed international certifications including CE, UN38.3, and MSDS, meeting global transportation and market requirements for lithium battery products.
These certifications ensure safer international shipping by sea and air and support overseas distributors in expanding their energy storage business.
