Over temperature
No electrical ground Ground loss
1.Disconnect AC circuit
breaker first. Then,
disconnect DC circuit
breaker.
2.Until LCD screen
completely shuts down,
turn on DC breaker first.
It will show “No Utility”
in LCD screen. Then, turn
on AC breaker. After 300
seconds, the system will
automatically connect to
the grid.
3.If the error message
still remains, please
contact your installer.
1.The internal
temperature is higher
than specified
temperature.
2.Leave inverter to be
cooled to room
temperature.
3.If the error message
still remains, please
contact your installer.
PV input voltage
exceeds the upper
threshold
1. Check if the open
circuit voltage of PV
modules is higher than
500VDC.
2. If PV open circuit
voltage is less than
500VDC and the error
message remains, pelase
contact your installer.
09
Auxiliary power*
failed
*Auxiliary power
means switch power
supply.
1. Turn off the inverter.
2. Then, restart the
inverter.
3. If the error message
still remains, please
contact your installer.
10
Leakage current
exceeds the
allowable range
1. The ground voltage is
too high.
2. Please disconnect AC
breaker first and then DC
breaker. Check if
grounding is connected
properly after LCD screen
completely shuts down.
3. If grounding is
correctly connected, turn
on DC brearker. After it
displays “No Utility” in
LCD screen, turn on AC
breaker. After 300
seconds, the system will
automatically connect to
the grid.
4. If the error message
still remains, please
contact your installer.
12
PV insulation
resistance is too low
1. Check if the
impedance between
positive and negative
poles to the ground is
greater than 1MΩ.
2. If the impedance is
lower than 1MΩ, please
contact your installer.
13
A difference
occurred in the
readings from the
main and secondary
controllers
1. Please disconnect AC
breaker first and then
disconnect DC breaker.
2. After LCD screen is
completely off, turn on
DC breaker. Until it
shows “No Utility” in LCD
display, turn on AC
breaker. After 300
seconds, the system will
automatically connect to
the grid.
3. If error message
remains, please contact
your installer.
