DCEMS-CCU-2
The convergence cabinet is the “brain” of the energy storage power
station. It connects to the shutdown meter, energy storage meter, and
the energy storage cabinet via network or serial ports. It collects
real-time data and status information from the station’s grid points,
energy storage equipment, and loads. This enables real-time
monitoring, fault diagnosis, safety protection, and energy
optimization. The device also supports cloud platform integration,
allowing data upload and remote control commands from the cloud.
