Product Description

This product is engineered for premium energy storage applications, featuring high-quality lithium iron phosphate (LiFePO₄)  battery cells, that deliver higher energy density, more reliable performance and longer service life than conventional batteries.   
The system supports high-current operations up to 100A for both charging and discharging, enabling seamless power supply for high-load appliances including refrigerators, air conditioning units, and washing machines. Pure sine wave output ensures power stability and  equipment protection.

Our products integrate RS485 and CAN bus communication interfaces, complemented by an intelligent BMS that provides real-time monitoring of overcharge, over-discharge, short-circuit, and thermal anomalies to guarantee operational safety and system efficiency. The optimum operating temperature ranges support charging from 0°C to 40°C and discharging from -20°C to 40°C, covering most climatic requirements. Certified to deliver 6,000 cycles at 80% depth of discharge (DOD), the product features an IP20-rated housing that maintains operational integrity across 5-95% humidity ranges, ensuring reliable performance under extreme environmental conditions.

Suitable for energy-independent households, off-grid installations, critical appliance backup power, medical equipment power supply, and outdoor workstation electrification, etc. This product is your optimal choice for efficient, stable and sustainable energy management.
