Product Description
Product Overview
This product is a centralized energy storage converter that enables AC-DC conversion between the power grid and energy storage batteries, facilitating bidirectional energy flow between the two. The product features real-time adjustable active and reactive power as well as adjustable DC voltage stabilization. In energy storage systems, the PCS power supply can suppress power fluctuations in the storage system and reduce the impact on the power grid. When the grid requires it, the PCS power supply can provide local reactive power compensation. In industrial applications, this product, combined with the motor controller’s inverter unit, can enable four-quadrant operation of motors, thereby supporting energy recovery.
