NO TE
● The components in the dotted box are optional.
● The inverter model is subject to change. The model information and device appearance
in this document are for reference only.
● In the networking, the inverter where the Dongle is installed is the master inverter, and
other inverters are slave inverters. Slave inverters can communicate with the Dongle
through cascading.
● When multiple inverters are cascaded, only one Smart Dongle or SmartLogger can be
connected to the RS485 communications link.
● The Smart Power Sensor connects to the RS485-2 and RS485_2 ports, or 485B2 and
485A2 ports on the master inverter. The RS485-1 and RS485_1 ports, or 485B1 and
485A1 ports are used for inverter cascading.
