Grid Fault
(Grid Volt)
(Grid Freq)
Grid measured
data is beyond the
specification
(voltage &
frequency)
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. Disconnect and
reconnect the AC grid to
see if inverter can be
operated normally
2. If problem still occurred,
check the reading value
of AC grid from the LCD
display of Inverter.
3. If this problem occurs
seldom (such as 1 time
a day), no action is
necessary
4. If the problem occurs
frequently, do the
actions below
5. Find the device with high
power consumption
near your AC system
6. Use Inverter software to
check the setting of
Inverter. The setting
should be in the range
listed in specification
7. If the settings are not
correct, call your service
for changing
8. Use Inverter software or
monitoring device to
collect data. Send the
data to professionals for
further investigation
9. Consult your utility
power supplier,
understand the grid
conditions
10. Request help from the
installer
1. Disconnect and
reconnect the AC grid
to see if inverter can be
operated normally
2. If problem still
occurred,, check the
reading value of AC grid
from the LCD display of
Inverter.
3. If reading value is within
specification, check the
system connection
including polarities and
security first
4. Find the devices with
high power
consumption near the
AC system
5. Consult the utility power
supplier, understand
the grid conditions
regarding the local grid
code
6. Use Inverter software to
monitor the frequency
and voltage
7. If the measured data
beyond the setting,
under the permission of
utility supplier, use the
software to change
parameters
8. If the situation is not
improved after
changing parameters,
please
9. Update the firmware
according to
instructions, or
10. Replace the Inverter
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
2. Check the AC wiring
3. If the problem continues,
call your local service
1. Make sure the breaker and
switch on AC side are
close
2. Check the AC wiring
3. If the problem continues,
replace the Inverter
PV over
Voltage
The detected PV
voltage is higher
than specification
1. The PV array
voltage is too high
2. DC input side of
Inverter is
abnormal
1. Open DC connection of
Inverter and reconnect
2. If the fault continues, call
your local service
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
