Note: if it is connected to the power or
generator, the terminal short films
between R/S/T must be removed, or
will cause the fires, and even
casualties risk

Figure 2-2 PV Cell Power Supply Wiring Diagram 2
1. Please wirings as Figure 2-1 or Figure 2-2 according to different inverter powers, check and confirm
the wirings to be correct, and then close Q1.
2. Setting the Motor Parameters
Setting the parameter of name plate on motor F08.01～F08.05。
3. Testing the water yield of pump
Press the operation key “RUN”, under normal circumstance of light strength, if the operation
frequency low or water yield less, which means the motor wiring may be reversed, please exchange
two wirings of motor.
4. System Effluent Speed PI Regulating
If the user has a high requirements for the effluent speed, PI parameters can be regulated
appropriately（H00.09～H00.10）, the larger PI parameter, the stronger affection, the faster effluent,
but the larger fluctuation of motor frequency; Otherwise, the slower water effluent, the more steady
frequency of motor operation.
5. MPPT Tracing Speed Commissioning
H00.04 and H00.05 are respectively the lowest voltage and highest voltage under the MPPT mode,
the smaller the range between them two, the faster tracing the maximum power, but the premise if
that the bus voltage during normal operation must fall within this range, or the maximum power point
may not be tracked. Generally speaking, the factory default value is OK.
