Market Advantages:

Our Energy Storage Inverter (PCS) effectively addresses the intermittency issues of solar power generation systems, significantly enhancing the flexibility and reliability of energy utilization. With continuous technological advancements and growing market demand, our PCS is poised to become an indispensable component in future energy systems.

A power conversion system (PCS) serves as a vital link between energy storage batteries and the power grid, enabling bidirectional energy conversion. When excess power is generated, the PCS charges the batteries, while it supplies stored energy to the grid when extra power is required. Consisting of AC/DC bidirectional converters, control units, switching elements, and cooling mechanisms, the PCS is a complex system.

Multiple layers of remote control are integrated into the system, facilitating precise regulation of battery charging/discharging and grid power supply. These controls are essential for maintaining the stability of the energy storage system. Additionally, the PCS interfaces with the battery management system (BMS) through various protocols like RS-485, CAN, Fibre-Optics, and Ethernet. This enables real-time monitoring of battery pack and cell conditions, ensuring safe charging and discharging operations and uninterrupted energy storage system functionality.
