when RS485
communication is used,
you are advised to set
PLC communication
to

Upgrade delay
Upgrade delay
is mainly
used in the upgrade
scenarios where the PV
power supply is
disconnected at night due
to no sunlight or unstable
at dawn or dusk due to
poor sunlight.
N/A
Disable
Enable
After the inverter upgrade
starts, if
Upgrade delay
is
set to
Enable
, the upgrade
package is loaded first. After
the PV power supply
recovers and the activation
conditions are met, the
inverter automatically
activates the upgrade.
22
String monitor
The inverter monitors PV
strings in real time. If any
PV string is abnormal
(such as being shaded or
with decreased energy
yields), the inverter
generates an alarm to
remind maintenance
personnel of timely
maintenance.
N/A
Disable
Enable
If PV strings are easily
shaded, you are advised to
set
String monitor
to
Disable
to prevent false
alarms.
23
String detection
low power
delay
Specifies the delay time
for generating abnormal
string alarms when the
inverter detects that a PV
string is working with low
power. This parameter is
mainly used in the
scenario where PV strings
are shaded for a long time
in the morning and
evening, and is used to
prevent false alarms.
