NOTICE
• Make sure that the communication device is connected to the right COM port. Route the
communication cable far away from any interference source or power cable to prevent the
signal from being inuenced.
• Enable the DRED, RCR or remote shutdown function via SolarGo App after cable
connections.
• If the inverter is not connected to the DRED device or remote shutdown device, do not
enable these functions in the SolarGo App, otherwise the inverter cannot be connected to
the grid for operation.
• To realize functions such as load control, remote shutdown, DRED/RCR, the communication
cable have to be connected to the master inverter. Otherwise, the functions cannot work
properly.
