This high-capacity 15kWh Lithium Iron Phosphate (LiFePO4) battery is a premium energy storage solution designed for large-scale residential and commercial solar installations. Engineered for 48V hybrid and off-grid inverter systems, it provides a massive 300Ah capacity, ensuring long-duration backup and exceptional reliability. With an advanced built-in BMS and support for high-current discharge, it is perfectly suited for powering heavy appliances like air conditioners, pumping machines, and industrial equipment.
Grade A LiFePO4 Cells: Utilizes premium Lithium Iron Phosphate technology for superior thermal stability, safety, and a lifespan exceeding 10–15 years.
Intelligent BMS Protection: The integrated Battery Management System (BMS) monitors cells in real-time, protecting against overcharge, over-discharge, over-current, and short circuits.
High Depth of Discharge (DOD): Safely utilize up to 90%–95% of the battery’s total capacity without compromising long-term health, compared to only 50% for lead-acid batteries.
Seamless Inverter Integration: Supports CANbus and RS485 communication protocols, making it fully compatible with leading hybrid inverters like Deye, Felicity, Growatt, and Victron.
Modular & Scalable: Designed to grow with your energy needs; supports parallel connection of up to 15–16 units for massive energy storage banks.
Robust & Compact Design: Available in floor-mounted or wall-mounted configurations with heavy-duty SPCC or aluminum casing for maximum durability.
