The FelicitySolar High Voltage Battery Cluster Controller (Master) is a professional battery management device designed for high-voltage lithium battery clusters in large solar and hybrid systems. As the master controller, it coordinates multiple battery modules, providing centralized monitoring, protection, and balancing to ensure safe and efficient operation.

The controller continuously monitors voltage, current, temperature, and SoC, and triggers protective actions against over-voltage, under-voltage, over-current, and over-temperature. With advanced communication and remote monitoring support, it integrates seamlessly with hybrid inverters and energy systems, making it ideal for commercial and industrial applications.
