Start-up 81
Note: When I2I link is in use, by default the control unit shows the combined
production data of the inverters connected to the same I2I link. This function is called
Multi Unit View and it can be disabled or enabled from the Screen Menu.
When adequate DC voltages are available from
the solar array, the inverter switches to get its
power from the solar array side. The inverter
will then make a series of system safety
checks. If safety checks are OK the inverter will
connect to the AC grid.
Setting up remote control unit interface
For remote installation with a cable or wireless transceiver, please refer to Electrical
installation on page 57. Also see PVS-APK-F control unit wall mounting kit for PVS300
string inverters installation guide (3AUA0000108440 [English]) and PVS-APK-M control
unit table stand and wireless communication kit for PVS300 string inverters installation
guide (3AUA0000100644 [English]).
Setting up I2I interface for 3-phase system configuration
Set I2I node addresses so that they are different for each unit. For example, 1, 2 and 3.

3 phase monitoring, set the following parameters:
74.01 Node address. Set the node address of the inverter to match the AC grid phase.
For example, phase L1 to address “01”, L2 to “02” and L3 to “03”.
75.01 Enable 3 phase monitoring. 0=disabled (default), 1=enabled.
75.02 Normal operation. 0=do not limit power (default), 1=limit power.
75.03 Comm timeout limit. 0=no timeout supervision, 1-255=comm. loss duration before
timeout action is invoked (seconds). Default setting: 30 seconds.
75.04 Comm timeout action. 0=limit power (default), 1=disconnect from grid.
75.05 Device fault time. Device fault duration of another inverter before device fault action
is invoked. Default setting: 0 seconds.
75.06 Device fault action. 0=limit power (default), 1=disconnect from grid.
75.07 Grid fault time. Grid fault duration of another inverter before grid fault action is
invoked. Default setting: 0 seconds.
75.08 Grid fault action. 0=limit power (default), 1=disconnect from grid.
