Failure Description Details Troubleshooting
OH1
Overheat of
rectification module
Blocked air duct or damaged
fan; Environmental
temperature too high;
Over-load operation too long
time .
Dredge the air duct or replace the fan;
Reduces environmental temperature
for overheat fault of OH2 inverter
module;
OH2
Overheat of inverter
module
EF
External fault
DI external fault input
terminal acts;
Inspect the input of external
equipment
END
Running time is up
The actual running time of the
Product is longer than the
internally set running time
Seek suppliers to help adjust set run
time
OL3
Electronic overload
fault
Overload warning of the
Product is given according to
the set value
Inspect load and over-load warning
point
ETH1
Short circuit to
ground fault 1
The output of the Product is
short circuited to ground;
current testing circuit is failed Inspect whether motor wiring is
normal; replace Hall; replace the main
control panel
ETH2
Short circuit to
ground fault 2
LL
Electronic
underload fault
The inverter will report the
underload pre-alarm
according to the set value.
Check the load and the underload
pre-alarm point.
PINV
PV reverse connection
fault
Incorrect PV wiring
Change the wiring direction of the
positive and negative terminals and
connect the cables again.
PVOC PV overcurrent
1. The acceleration or
deceleration is too fast.
2. The inverter power is too
low.
3. The load transients or is
abnormal.
4. The grounding is short
circuited.
1. Increase the ACC or DCC time.
2. Select the inverter with a larger
power.
3. Check if the load is short circuited
(the grounding short circuited or the
wire short circuited) or the rotation is not
smooth.
PVOV PV overvoltage
1. The solar cell panel input
voltage is too high.
2. Model -4 is set as another
model.
1. Reduce the number of solar cell
panels that are wired in series.
2. Check and reset the model.
PVLV PV undervoltage
1. The power of the solar cell
panel series is too low or it is
cloudy and rainy weather.
2. The motor start-up current
is too high.
1. Increase the number of solar cell
panels or perform the test in the
normal sun light.
2. Change the motor.
A-LS
Weak light warning
Weak solar irradiance, or too
little configuration of cell
panel
After the light is strong, the device
will run automatically, and the user
does not need to pay attention; please
inspect if the configuration of cell
panel is reasonable.
A-LL
Under-load warning Empty suction basin Check the pumping pool
