Product Description

This product is engineered for premium energy storage applications, utilizing high-quality lithium iron phosphate (LiFePO₄)  battery cells, that deliver higher energy density, more reliable performance and longer service life than conventional batteries,with a proven cycle life of 6,000 cycles.    
Featuring a modular high-voltage design and standardized 50A rated current, our product ensures high-performance charging and discharging, seamlessly powering high-load appliances including refrigerators, air conditioning units, and washing machines. Pure sine wave output guarantees grid-quality power stability for optimal 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. Designed for exceptional environmental resilience, it operates reliably across 5%~65% humidity ranges and -15°C~45°C temperature conditions.

The flexible dual-mode architecture supports both grid-tied and off-grid configurations, enabling seamless integration with solar, wind, and other renewable energy sources.

With a space-saving stackable design, the 32S1P can be connected in series (height scales with capacity) to simplify installation in medium and high energy demand scenarios. It is suitable for energy-independent households, small commercial establishments, off-grid residences, multi-family units, backup power for critical equipment, and outdoor workstation power supply, etc. This product is your optimal choice for efficient, stable and sustainable energy management.
