29 HPS-1000/1500/2000/2500/3000 USER MANUAL
⒊If it cannot be recovered for a long time, please confirm:
①whether the AC circuit breaker is disconnected
②whether the AC terminal is in good connection
③whether the power supply line is normal
④ whether the safety regulation settings are normal
12
DC component of
the electricity
exceeds the
permissible range
the current exceeds 1A in
stastic state and 4A in
dynamic state
Disconnect the inverter from the utility grid and the PV array, and
reconnect it after LED turns off. If this fault is still being displayed,
please contact the service.
13
EEPROM Error, e.g.
transition
disturbance
Micro CPU read EEPROM
failed
Disconnect the inverter from the utility grid and the PV array, and
reconnect it after LED turns off. If this fault is still being displayed,
please contact the service.
14
Internal
communication
fault
Master CPU communicate
with slave CPU abnormal
Disconnect the inverter from the utility grid and the PV array, and
reconnect it after LED turns off. If this fault is still being displayed,
please contact the service.
15
Bus-voltage too
high
Bus-voltage is greater than
500V
Check the open-circuit voltages of the strings and make sure it is
below the maximum DC input voltage of the inverter.
If the input voltage lies within the permissible range while the
fault occurs, please contact the service.
16
Bus-voltage too
low
Bus-voltage is 20V lower
than standard Bus-voltage
Check the open-circuit voltages of the strings and make sure it is
below the maximum DC input voltage of the inverter. If the input
voltage lies within the permissible range while the fault occurs,
please contact the service.
17
DRM S9 Error
DRM switch S9 fault
Check the connection of DRM device. If the DRM device is
connected normally while this fault occurs, please contact the
service.
