High
PVx
Input
current
(x=1,2…12)
1.
Restart inverter by recycle both AC and DC
switches.
2.
Wait for 1 minute between OFF and ON for
all energy to discharge.
3.
Contact after-sales service personnel.
High
PVx
Input
voltage
(x=1,2…12)
1.
Check if its input voltage is within 1100V;
2.
Restart inverter by recycle both AC and DC
switches.
3.
Wait for 1 minute between OFF and ON for
all energy to discharge.
4.
Contact after-sales service personnel.
PVVoltOver
1.
Measure voltage at DC terminals in wiring
box and compare with reading in
Measurement menu. PV voltage must be
less than 1000V in open circuit condition.
2.
If display reading is not within 2% of meter
reading, replace inverter.
3.
If display reading is within 2% of meter
reading, adjust number of panel in the string.
Protect0230
(Inverter open-loop
self-test fault)
1.
Restart inverter by recycle both AC and DC
switches.
2.
Wait for 1 minute between OFF and ON for
all energy to discharge.
3.
If inverter cannot clear fault, replace inverter.

Faults
Fault0130
(Bus
over
total
voltage)
1.
Restart inverter by recycle both AC and DC
switches.
2.
Wait for 1 minute between OFF and ON for
all energy to discharge.
3.
If inverter cannot clear fault, replace inverter.
Fault0110
(Bus imbalance)
1.
Raise limit of IDCmax (for example, 400mA)
to allow inverter more room to adjust in
transient condition to cope with imbalance of
impedance and voltage between Grid
phases
2.
If after adjustment, alarm still occurs, replace
inverter.
Fault0100
(Grid relay fault)
1.
Restart inverter by recycle both AC and DC
switches.
2.
Wait for 1 minute between OFF and ON for
all energy to discharge.
3.
If inverter cannot clear fault, replace inverter.
Fault0090
(Static
leakage
current high)
Check wires of PV and ground:
1.
Turn OFF AC switch to disconnect inverter
from Grid.
