Along with the various operating states, various messages may be shown on the
display, as follows.
State
Error code
Description
Causes
Initializat
-ion
Waiting
Initial PV voltage is between minimum DC
input voltage and the start-up DC input
voltage of the inverter.
Checking
The inverter is checking the feed-in
conditions after the start-up PV voltage
exceeds the initial DC input voltage of the
inverter.
Reconnect
The inverter is checking feed-in conditions
after the last fault has been solved.
Normal
Normal
The inverter is operating normally.
Fault
9
GFCI Fault
Ground-fault detection circuit is abnormal
8
AC HCT Fault
Output current is abnormal
6
High DC Bus
The voltage of DC busbar exceeds the
permitted upper limit.
35
No Utility Grid
Available
The utility cannot be detected, which may be
caused by no utility, grid disconnected, AC
cables damaged, fuse broken or
stand-alone grid.
40
Over Temp.
The internal temperature exceeds the
permitted value.
33
Fac Fault
The grid frequency is outside the permitted
range.
34
Vac Fault
The grid voltage is outside the permitted
range.
37
PV Overvoltage
The voltage of the strings exceeds the
permitted upper limit.
36
Ground Fault
The residual current exceeds the permitted
upper limit.
4
DC INJ. High
Output DC feed-in exceeds the permitted
upper limit.
