7.1 Commissioning the WIT Inverter
● The WIT Inverter might show wrong time and date if it has been stored for
over a month. You need to set the correct time and date before connecting the
WIT Inverter to the grid.
7.1.1 Set the Communication Address
After the WIT Inverter is powered on, you can set the communication address of the WIT Inverter
via RS485 communication or the USB to Wi-Fi module. When multiple inverters are connected in
parallel with RS485 hand-in-hand communication, each inverter should be set to different
communication addresses. For a single inverter, the default communication address is set to1.
NOTE: The communication address of the WIT Inverter ranges from 1 to 254.
By connecting the WIT Inverter to the host computer through RS458 communication, you can
change its communication address via ShineBus. This operation should be performed by
professional personnel.
