This 400V 120Ah industrial and commercial energy storage battery is specifically designed for medium-sized enterprises and facilities. It adopts a high-voltage platform to enhance energy efficiency and reduce line losses, supports modular parallel expansion to meet flexible deployment requirements. Its built-in intelligent BMS system integrates overcharge/overdischarge protection, temperature monitoring, and equalization management functions. Combined with air-cooling technology, it ensures stable operation in a wide temperature range and is suitable for scenarios such as factory backup power, photovoltaic power absorption, and load regulation. While achieving a 90% deep discharge, it supports remote energy dispatch through communication interfaces and provides a safe, reliable, and low-maintenance sustainable power solution.
