Parameter
Description
Hibernate at
The device performs the
night
monitoring function at night.
If this parameter is set to
Enable, the monitoring
function of the device will
hibernate at night to reduce
power consumption.
Upgrade delay
This parameter is mainly used
in upgrade scenarios where
the power supply at DC side
is disconnected.
RCD
RCD refers to the residual
enhancement
current of the inverter to the
ground. To ensure device and
personal safety, RCD should
be limited to the specified
value in the standard. If an
AC switch with a residual
current detection function is
installed outside the inverter,
this function should be
enabled to reduce the
residual current generated
when the inverter is running,
thereby preventing the AC
switch from misoperations.
PID
When the external PID
compensation
module compensates the PID
direction
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.

Remarks
-
After the upgrade
starts, if Upgrade
delay is set to
Enable, the upgrade
package is loaded
first. After the DC
side power supply
recovers and the
activation conditions
are met, the device
automatically
activates the
upgrade.
-
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.
