A PCS module (Power Conversion System module) is the core bidirectional power conversion unit within an energy storage system. It is responsible for converting electricity between DC (battery side) and AC (grid side), enabling controlled charging, discharging, and grid interaction.
In commercial and industrial projects, PCS modules are widely used by system integrators to build:
Our Mars Series PCS modules are specifically engineered to handle complex grid conditions and demanding operating scenarios. The solution supports high- and low-voltage ride-through (HVRT/LVRT), black-start capability, and off-grid parallel operation, ensuring stable performance even in weak-grid environments.
Designed with advanced grid-support functions, the Mars Series bidirectional power module improves grid compatibility and enables stable operation in high-renewable penetration scenarios.
As a professional bidirectional power module manufacturer, we develop our PCS modules with a strong focus on efficiency, intelligent control, and modular scalability—ensuring seamless integration into diverse C&I energy storage architectures.
As an experienced bidirectional power module manufacturer, we specialize in the R&D and innovation of energy storage power conversion technologies. Since our establishment, we have focused on mastering core PCS technologies and have steadily grown into one of China’s leading suppliers of C&I PCS modules and microgrid solutions.
