Description
The inverter monitors PV strings in real time. If any PV string is abnormal
(such as the PV string is shaded or the electric energy yield decreases), the
inverter generates an alarm to remind maintenance personnel to maintain
the PV string in a timely manner.
If PV strings are often shaded, you are advised to set String monitor to
Disable to prevent false alarms.
Specifies the threshold for determining PV string exception. The false
alarms caused by fixed shadow shading can be controlled by changing this
parameter.
This parameter is displayed when String monitor is set to Enable.
Specifies the threshold for starting PV string exception detection. The false
alarms caused by fixed shadow shading can be controlled by changing this
parameter.
This parameter is displayed when String monitor is set to Enable.
The standards of certain countries and regions require that the inverter
should not disconnect from the power grid if the power grid experiences a
short-time failure. After the fault is rectified, the inverter output power
needs to be quickly restored.
