Parameter Range of val-
ues Description
"Automatic Re-
connects" If more fault currents have been detected
within 24 hours than are defined in "Auto-
matic Reconnects", the inverter will not
make any further attempt to start feeding
energy into the grid. The status code 1076
is displayed on the user interface of the in-
verter and must be acknowledged manu-
ally.
0 No fault current above 300 mA is toler-
ated. After each detected fault current,
feeding energy into the grid is interrupted
and the status code must be acknow-
ledged manually on the user interface of
the inverter.

4 After a shutdown due to a fault current ex-
ceeding 300 mA, 1, 2, 3 or 4 attempts are
made within 24 hours to restart feeding
energy into the grid. After this number of
attempts, no further attempt is made to
start feeding energy into the grid and the
status code must be acknowledged manu-
ally on the user interface of the inverter.
Unlimited The 24 hour counter is deactivated. The in-
verter restarts feeding energy into the grid
after each detected fault current above
300 mA.
DC Shutdown
Communication Devices for shutdown within the DC generator (e.g. in or on the module or within
a string) can be controlled by the inverter. The condition for this is compatibility,
especially with the communication of the inverter.
Parameter Range of val-
ues Description
"Powerline
Communica-
tion" Activates and deactivates DC Powerline
Communication (PLC) on the inverter.
PLC Off DC Powerline Communication is deactiv-
ated on the inverter. There are no shut-
down devices installed in the PV system,
or if shutdown devices are installed in the
PV system that are waiting for an enable
signal, then this signal must come from
another device (transmitter) (otherwise
the system will not function).
SunSpec PLC The inverter communicates with DC-
Powerline Communication according to
the "SunSpec Rapid Shutdown Standard".
Compatible shutdown devices must be
used for the correct functioning of the PV
system.
