Description
Adjusts the sensitivity of
arc detection.
Send the AFCI self-test
command manually.
When the IV curves of PV
strings are being scanned,
the current change of PV
strings operating properly
should be monitored to
avoid inaccurate scanning
caused by sunlight
change. If the current
exceeds the specified
value, it is determined that
the sunlight changes, and
the IV curves should be
scanned again.
If this parameter is set to
Enable, the inverter shuts
down after receiving the
OVGR signal. If this
parameter is set to

not shut down after
receiving the OVGR
signal.

SmartLogger.
The inverter monitors PV
strings at night. If
Hibernate at night is set

function of the inverter
will hibernate at night,
reducing power
consumption.
