"power-on waiting" delay, the controller will immediately enter the "normal operation" state, and
then soft load to the target active power/reactive power percentage obtained according to the
power control mode to complete the whole boot process.
4.5.3 AUTO STOP SEQUENCE
a)
HES7120-PV during normal operation of PV power generation, if the alarm set by the busbar is
only a warning or an indicating alarm, if the busbar is abnormal (over voltage, under voltage, over
frequency, under frequency, phase loss, and inverse phase), it will enter into "busbar abnormal
delay". The status page of LCD shows the countdown. Or when the input of remote power on fails,
"stop delay" will start. If the alarm set by busbar or PV has the alarm of shutdown, trip shutdown and
trip non shutdown, the PV power generation closing relay will be disconnected and the controller will
enter the shutdown sequence after the alarm is sent, and the opening will be completed after the
closing feedback is invalid (if configured), otherwise, if the closing feedback is still valid, the LCD
status page will display "waiting for PV to open", and the LCD Alarm page will display the switch
fault alarm.
b)
After the shutdown delay, soft unloading will be started. When the unloading reaches the set
unloading value, the controller will enter the "shutdown cooling" delay (if configured), and the PV
will start to open (refer to B for the opening step).
c)
After the "shutdown and heat dissipation" delay, the controller will enter the "on-going shutdown"
mode, and send the shutdown command to the inverter through RS485. If the controller does not
receive the valid shutdown command within the "on-going shutdown" delay, it will enter the
"shutdown failure" mode, and the LCD Alarm page will display the shutdown failure alarm. If the
controller receives the valid shutdown command within the "on-going shutdown" delay, it will
immediately Enter "stop waiting" and wait for the inverter to stop working.
d)
If the controller does not receive the inverter stop command after the "stop waiting" delay, enter
"stop failure", and the LCD Alarm page displays the stop failure alarm.
e)
If receiving the inverter stop working command, enter PV standby state.
