ONNECTING TO THE
The PV Power Control Box is an accessory that allows remote control over
limiting the output power from the inverter, reactive power generation and
the feeding or standby status. It is a requirement of grid regulations in some
countries. For more information, refer to the accessory manual.
The communication interface must be set to operate with 2 wires (RS485)
and the last bus inverter must have active termination. Referring to the PC
Power Control Box manual, connect the inverter bus to the "serial 2" port as
shown in the table on the right. The monitoring device (PC or other) must be
connected to the RS232 "Serial 1" port of the PV Power Control Box.

UILT IN DATALOGGER
The inverter has a built-in datalogger which saves instantaneous data at a frequency that can be selected using the software of
between 5 minutes (average annual capacity of 7 days of data) and 60 minutes (average annual capacity of 84 days of data), as
well as saving the production data once a day for two years.
The inverter automatically overwrites less recent data when the memory is full.
