setting is obtained, press the “Setting” button for about 3 - 5s until the PV inverter
making a beep to indicate the completion of setting. At this time, release the
“Setting” button to enter the 3rd layer of output frequency setting (LOAD LED 3 is
lighted).

The 3rd layer is the output frequency setting as described below:
Step 1:
Please refer to the LED signal comparison detailed in Table 3.3 to
determine whether the setting is of a desired output frequency. If it is correct,
please press and hold the “Setting” button for 3 – 5s until the PV inverter emits a
beep before completing the frequency setting, and enter the preview mode, which
means Run, Min.ALM and Maj.ALM will be all lighted, LOAD LED1~4 is lighted,
and 10s later, the inverter will be automatically restarted. Then the inverter output
will be based on the latest setting values. If not, please follow the Step 2 for
setting the output frequency.
Step 2:
Please press and hold the “Setting” button for about 1s and then
release it. In this way, the light signal changes for each press. And after adjusting
it to the required frequency, press the “Setting” button for about 3 – 5s until the PV
inverter sounding a beep to indicate the completion of frequency setting (LOAD
LED4 is lighted implying the completion of setting), At this time, restart the PV
inverter to save the settings, and the inverter output will be based on the latest
setting values.

3.5 Monitoring Software (Optional)
Users can use monitoring software to set or adjust the operating modes,
output voltage, frequency and the voltage conversion sections by connecting the
inverter RS485 port with a computer. Please refer to our website or contact a local
dealer for more information.
3.6 Protection and Malfunction Warning Display
(A)Battery OCP: When the battery input is over-current, the fuse at inverter
battery input terminal will blow and it cannot be used as normal. When that
happened, please contact a local dealer or return the appliance to manufacturer
for a repair.
(B)PV Reverse Connection Protection: When the PV input is reversely
connected, the PV inverter will stop operating and the corresponding LED light
indicator light is extinguished. Please re-connect the PV inverter when that
happened.
(C)AC Output SCP: When an output short circuit occurs, the output will be shut
down and the Maj. ALM is lighted. Then the PV inverter needs to be restarted.
(D)AC Output SCP: When output short circuit occurs, the output will be shut
down and the Maj.ALM is lighted. Then the power switch of PV inverter needs to be
restarted.
