Description

This energy storage system uses lithium iron phosphate (LiFePO₄) anode materials, providing superior safety, long lifespan, and reliable performance. Fully managed by an advanced Battery Management System (BMS), it protects against over-discharge, over-charge, over-current, and abnormal temperatures while enabling self-management of charging, discharging, and single-core balancing. Certified to European ROHS and SGS standards, the system is environmentally friendly, non-toxic, and pollution-free. Its modular design allows multiple batteries to be connected in parallel for extended standby time. Features include low self-discharge (up to six months storage), no memory effect, self-ventilation with low noise, and excellent high-temperature performance (-20°C to 65°C). Lightweight and compact, it delivers high energy density while maintaining flexible installation options. Ideal for homes, businesses, and renewable energy systems requiring safe, efficient, and long-lasting energy storage.
