is required to operate the device. The EMS/PMS must be provided by the customer/
system integrator. Modbus TCP is the sole means of communication with the device.
The necessary commands and data points are described in the SunSpec Protocol description [See sec-
tion 1.1
The shutdown threshold (DC-Min.) is dynamically determined by the device on the basis of the current grid
voltage. After shutting down the device, it is therefore not possible to guarantee reconnection as there may be
a change in the grid voltage.
