F12.32 ~ F12.41 defines the PQ curve, which can be used for users to set 5 groups of PQ
corresponding points according to the water pump situation to realize real-time flow rate, daily
flow rate and cumulative flow rate calculation.

F12.42 and F12.43 are used to adjust the display flow speed;
Display flow speed = real-time calculation flow speed *F12.43+F12.42.

According to F12.44, determine the daily flow and daily power generation calculation cycle.
6.2 Ooperation instructions for asynchronous motor pumps
(1) Wiring
①
Confirm whether the type of frequency converter and solar panels match.
②
Connect the solar panel "+", "-" terminals to the inverter "R", "T" or "+", "-" bus.Please
note that the "+" and "-" connected to the frequency converter cannot be reversed, otherwise it will
blow up the plane.
③
Connect the inverter's U, V, W to the motor, and ground of inverters connection motor
ground wire.
(2) Parameter setting and trial run
①
Set F00.24=0 V/F mode operation, F01.15=0 keyboard operation, reasonable set F01.11
upper limit frequency, F01.12 lower limit frequency.
②
Set the F15 group of motor parameters
③
F12.00 is set to 1 or 2. Photovoltaic function enables, and set PV protection function
parameters F12.11~F12.29 according to requirements.
④
press the keyboard , Jog test run, check whether the motor running direction is
correct.
(2) Common problems
①
Water pump operation at good light,inverters reported A42 ~ A47 frequently ?
Answer: check the relevant function codes of F12 to see whether the protection value and
time of relevant functions are set reasonably.
②
Incorrect DC current display?
Answer: adjust F12.30 and F12.31 for calibration.
③
Inverter running at good light, but the frequency change quickly?
Answer: adjust the parameters of F12.05 and F12.06 reasonably. It is recommended to adjust
them near the default value.
