4.5 Power On and Commissioning
①
Check and make sure the wiring is correct. If necessary, check motor and cable
insulation with a megger;
②
Use a multimeter to check whether the Voc of the solar panels from the DC switch
meets the requirements or not;
③
Close the DC switch to power on the controller;
④
If necessary, modify and set the parameters of the motor as follows:
If the rated power of the motor is 60Hz, the following parameters need to be modified:
F0.10
（
maximum output frequency
）
=60.00,
F0.12
（
upper limit of running frequency
）
=60.00,
F2.04
（
motor rated frequency
）
=60.00
Other related parameters are: motor rated power F2.01, motor rated voltage F2.02,
motor rated current F2.03 ,motor rated frequency F2.04, motor rated speed F2.05.
Note: The default motor rated frequency is set as 50Hz.
⑤
Check the rotation direction of the water pump
Press the START/STOP button to start the motor briefly and slowly to check whether
the rotation of it is correct. If the pump is in a dry running state, the maximum running time
should not exceed 15s, otherwise the pump may be damaged. If the direction is wrong, turn
off the DC switch, then swap any two of the 3 cables connecting the motor and controller
U/V/W ports.
⑥
Stop to check the displayed bus voltage of the controller or use a multimeter to
measure the PV open-circuit voltage, and set FD.06 = actual open-circuit voltage value.
⑦
Trial operation, let the system work for one hour, check the water supply capacity,
if there is no problem, the commissioning is completed.
Note: When the light is insufficient, the output power of the solar panels will be
reduced, and the water pump will run very slowly until it stops. The controller will try to
start every 300 s, and the running indicator light will stay on during the time it tries to run.
When a shadow suddenly passes through the solar array, the controller will lose track of the
input voltage and the pump will stop working. But the controller will not display the fault,
tit will try to restart the pump.
