CoEpo-125kW Energy Storage Bidirectional DC/AC Converter

The CoEpo series energy storage converter (PCS) is an advanced power electronic device specifically designed for energy storage systems. It acts as a bridge for energy conversion, enabling efficient bidirectional conversion between direct current (DC) and alternating current (AC) during the storage and release of electrical energy, while also managing and controlling the charging and discharging of batteries. It is suitable for various working scenarios, including grid-connected, off-grid, and grid-connected/off-grid switching. With comprehensive functionality, it provides a one-stop integrated solution for power quality issues such as active/reactive power balance, harmonic current distortion, and three-phase load imbalance at the user site.
