Optionally, inverters with RSD function equips with a built-in signal transmitter to communicate
with module-level smart controller installed on the external of the PV strings. In case of
an emergency, by turning off the AC circuit breaker at the output side of the inverter, the
transmitter inside of the inverter will be cut off, consequently to interrupt the current output of
the PV strings.
Communications
The inverter supports parameter setting via Bluetooth, connecting to the SMES monitoring
platform via WiFi, 4G, or WiFi+LAN, thus monitoring the operations of the inverter and the
power plant, etc.
