12. Meanings of Error Messages and Their Remedies
Troubleshooting
Your PV-Inverter requires very little maintenance. When unexpected situation occurs, please refer to the following table should further assistance be
required before calling your local dealer. The following table lists common fault messages that display when the fault LED is lit, and their solutions.

Proposed Actions for Professionals
E2-3:Ground I Fault
The fault current
detected by the inverter
is higher than threshold.
1.
Obstacle, humidity or
water exits between AC
LINE and/or NEUTRAL
to earth ground.
2.
Obstacle, humidity or
water exits between AC
LINE and/or NEUTRAL
to earth ground in the
junction box.
3.
The Insulation of AC
wires is broken that could
be bit by rat or any
animals.
4.
Inverter is abnormal.
1.
Disconnect AC connection of
inverter by opening AC switch.
2.
Check the AC junction box and
wiring of system. Clear obstacle
ONLY IN SAFE CONDITIONS
3.
Reconnect AC connection, check
the status of inverter.
4.
If the problem persists, contact the
store from which you purchased
the product or your installer.
1.
Disconnect AC side of inverter by
opening AC switch.
2.
Disconnect the DC side from the
inverter.
3.
Check both the AC and DC wiring
and insulation.
4.
Reconnect AC connection, check
the status of inverter
5.
If the problem persists, please
replace the inverter.

E1-1: OV (AC over
voltage) error due to
rise in voltage from
the utility.
E1-2: UV (AC under
voltage) error due to
drop in voltage from
the utility.
E1-3: OF (over-
frequency) error due
to rise in frequency
from the utility.
E1-4: UF (under-
frequency) error due
to drop in frequency
from the utility.
E1-6: Islanding
operation detected
(active system) due to
error in the power
from the utility.
E1-7: Voltage from the
utility has exceeded
383 V.
1.
The detected AC voltage
is beyond/under the setting
of inverter.
2.
The detected AC
frequency is beyond/under
the setting of inverter.
3.
AC connection is not
correct.
4.
Grid condition is weak or
unstable.
5.
Other high-power
consumption device is
affecting the grid system.
6.
The setting of inverter is
deviated from its default
values.
7.
Inverter is abnormal.
1.
If this problem occurs seldom
(such as 1 time a day), no action is
necessary. Operation will restart
automatically when the voltage
from the utility returns to normal.
2.
If the problem occurs frequently,
do the actions below.
3.
Find the device with high power
consumption near your AC system.
4.
Use inverter software to check the
setting of inverter. The setting
should be in the range listed in
specification.
5.
If the settings are not correct, call
your service for changing.
6.
Use inverter software or
monitoring device to collect data.
Send the data to professionals for
further investigation.
7.
Consult your utility power
supplier, understand the grid
conditions.
8.
Ask help of your installer.
1.
Check the system connection
including polarities and security
first.
2.
Find the devices with high power
consumption near the AC system.
3.
Consult the utility power supplier,
understand the grid conditions.
4.
Use inverter software to monitor
the frequency and voltage.
5.
If the measured data beyond the
setting, under the permission of
utility supplier, use the software to
change parameters.
6.
If the situation is not improved
after changing parameters, please
replace the inverter.
E1-0:No Utility
Inverter is not able to
detect AC voltage.
1.
Grid is not available.
2.
AC connection is incorrect
3.
AC switch between
inverter and utility is not
ON.
4.
AC fuse and/or breaker is
open.
5.
Inverter is abnormal.
1.
Make sure the breaker and switch
on AC side are close. Operation
will restart automatically when the
voltage from the utility returns to
normal.
2.
Check the AC wiring.
3.
If the problem persists, contact the
store from which you purchased
the product or your installer.
1.
Make sure the breaker and switch
on AC side are close.
2.
Check the AC wiring.
3.
If the problem persists, please
replace the inverter.
E2-1:PV over voltage
The detected PV
voltage is higher than
specification.
1.
The PV array voltage is
too high.
2.
Inverter is abnormal.
1.
Open DC connection of inverter
and reconnect. Operation will
restart automatically when the
solar module output voltage
lowers.
2.
If the fault continues, contact the
store from which you purchased
the product or your installer.
1.
Check the open PV voltage, and
see if it is more than or too close to
specification.
2.
If PV voltage is much less than
specification and the problem still
occurs, please replace the inverter.
