4. Comm. & Monitoring
There are 2 communication ports on the inverter.
One is a 4-Pin COM port and the other is a 16-Pin COM port.
The 4-Pin COM port is used to connect Solis datalogging sticks
(Please refer to manuals of Solis datalogging sticks for details).
The 16-Pin COM port is used for multiple inverter daisy chain connection/DRM connection/
Logic Interface Connection/Meter connection.
The inverter package will include a 16-Pin COM connector to be used on this 16-Pin
COM port. The Pin definition is shown below. Facing the connector, Pin 1 is on the left
of the first row. The rest polarity is showing in below diagram.
