Description
When the external PID module compensates the PID voltage for the PV
system, set PID compensation direction to the actual compensation
direction of the PID module so that the inverter can output reactive power
at night.
This parameter is displayed when PV module type is set to Crystalline
silicon. Select PV–positive offset for P-type PV modules. Select PV+
negative offset for N-type PV modules.
Specifies the operation mode of the inverter built-in PID.
Specifies whether to enable the PID nighttime off-grid repair.
Specifies whether to enable the PID daytime off-grid repair.
Specifies the connection mode of PV strings.
 When PV strings connect to the inverter separately (All PV strings
separated), there is no need to set this parameter. The inverter can
automatically detect the connection mode of the PV strings.

When PV strings connect to one another in parallel outside the inverter
and then connect to it independently (All PV strings connected), set this
parameter to All PV strings connected.
The standards of certain countries and regions require that the inverter must
shut down after the communication is interrupted for a certain time.
If Communication interrupt shutdown is set to Enable and the inverter
communication is interrupted for a specified time (set by Communication
interruption duration), the inverter will automatically shut down.
Specifies the duration for determining communication interruption. Used
for automatic shutdown for protection in case of communication
interruption.
If this parameter is set to Enable, the inverter automatically starts after
communication recovers. If this parameter is set to Disable, the inverter
needs to be started manually after communication recovers.
Specifies the duration for the power to gradually increase when the inverter
starts.
The North American standard requires that the inverter should have DC arc
detection function.
Adjusts the sensitivity of arc detection.
Send the AFCI self-check command manually.
To prevent inaccurate scanning caused by sunlight change, the current
change of PV strings operating properly should be monitored when the I-V
curves of PV strings are being scanned. When the current exceeds the
specified value, it is determined that the sunlight changes. The I-V 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 Disable, the inverter does not
shut down after receiving the OVGR signal.
