Appendix 1: Fault information of storage inverter
Table 9-1 presents the visible fault types of storage inverter. From this table, users can simply and quickly identify the system faults
from the fault types displayed on touch screen. In multiple module parallel system, the warning information interface will indicate
the number of fault slaves and fault type.
Table 9-1 Fault information
Fault type Description
Overvoltage of power grid
The voltage of power grid is higher than the set upper limit. After faults are recovered, restart
the storage inverter.
Overvoltage of power grid
The voltage of power grid is lower than the set lower limit. After faults are recovered,
restart the
storage inverter
.
Inverted sequence of power grid
The phase sequence of AC power grid is inverse.
Abnormality of power grid frequency
Power grid frequency exceeds the set scope. After faults are recovered, restart the
storage inverter
.
Islanding of storage inverter
There is islanding in
storage inverter
.
Overvoltage of DC input
Overvoltage of DC input is higher than the upper limit. After faults are recovered,
restart the
storage inverter
.
Low DC voltage
Overvoltage of DC input is lower than the lower limit. After faults are recovered, restart
the
storage inverter
.
Abnormality of BUS bar voltage
DC BUS bar voltage is too high or low, which results in system shutdown. After faults
are recovered, restart the
storage inverter
.
Abnormality of balanced circuit
BUS bar voltage is imbalanced (internal fault information)
Soft start fault
Soft start fault (internal fault information)
Emergency shutdown
EPO action, emergency shutdown
Over-temperature of inverter
The temperature of inverter radiator is too high.
Fan fault At least one cooling fan has faults.
Monitoring parameter setting fault
Monitoring parameter setting is incorrect. Please modify the setting.
