5.2 SHUTDOWN ALARM

When controller detects shutdown alarms, it will send signals to stop the generator and the
corresponding alarm information will be displayed on LCD. When the alarm is enabled and the action
type is selected as shutdown, the shutdown alarm will be sent out.

Description
When the controller and the inverter communicate
normally, the controller will send out the warning
signal when receiving the inverter warning alarm.
Description
When the controller detects the corresponding data
value ≥ (overvoltage, overfrequency alarm, etc.) or
≤ (undervoltage, underfrequency alarm, etc.) the
set threshold value, the alarm is enabled and the
action type is selected, the controller will send out a
shutdown signal.
When the controller detects that the absolute value
of busbar power value (power is negative) ≥ the set
threshold value, the alarm is enabled and the
action type is selected to warn, the controller will
send out a shutdown signal.
When the controller detects that the power value of
the busbar (power is positive) ≥ the set threshold
value, the alarm is enabled and the action type is
selected, the controller will send out a shutdown
signal.
When the controller detects that the voltage
unbalance percentage of the busbar ≥ the set
threshold value, and the alarm is enabled and the
action type is selected, the controller will send out a
shutdown signal.
When the controller detects the corresponding data
value ≥ (overvoltage, overfrequency alarm, etc.) or
≤ (undervoltage, underfrequency alarm, etc.) the
threshold value, the alarm is enabled and the
action type is selected, the controller will send out a
shutdown signal.
When the controller detects the voltage imbalance
percentage of PV generation ≥ set threshold, alarm
enabling and the action type chooses warning, the
controller sends a shutdown signal.
When the controller detects that the absolute value
