SI23 Solar Pump Inverter Manual

1. Security Tips

1. Only qualified personnel can operate the equipment.

2. AC power supply should not be connected with output ports U, V, W,

otherwise there is a danger of damage to frequency inverter.

3. After electrified, it is forbidden to contact internal wiring board and its parts.

Otherwise it will cause the danger of electric shock

4. User can only operate on it after 5 minutes when cut off power.

（2）Connection for single phase motor

SI23 Solar Pump Inverter Manual

Notes: Single phase motor has three lines, first use the multimeter check the three

lines resistor, the biggest value two lines parallel the start capacitor (recommend

the capacitor volume is 150UF/250V), the other line(common-coil) connect the

power terminal. Then use the multimeter check the common coil with the other two

lines resistor, the lower one connects another power terminal.

6. Basic Operation

Motor debugging

（1）AM Pump

Default parameter one key start and stop

Same power level, determine the direction of operation （F0.16）

Adjust motor parameters and corresponding protection parameters

according to the application

（2）PMSM Pump

Set motor parameter（F5.00-F5.06，Motor series 、Frequency、Speed、

Voltage、Current、Power）

Rotating self-tuningF5.12(SI22 SI30), F5.20 (SI23)

Judge the direction of the pump

（3）Single Phase Pump

Connect the starting capacitor between the main coil and the auxiliary

coil

Shield output phase loss

Running judge the direction of the pump
