1. Safety Information and Important Warnings
⚠ WARNING: Electrical Hazard
- Read the user's manual before installing. Improper installation or operation can lead to serious injury or equipment damage.
- Do not open the cover while connecting power supply. Ensure the power supply is disconnected for at least 10 minutes after use before opening the cover to avoid electric shock from residual voltage.
- AC input and DC input switches cannot be closed at the same time. Doing so will damage the inverter or solar panel.
- Avoid Overload: Do not use the inverter with an overload. The inverter's power must be greater than the motor's power. Running an ordinary motor above 50Hz with an undersized inverter can cause frequent overload faults, damage to the inverter, or motor burnout.
- Voltage Requirements for Solar Panels:
- For a 220V motor, the total series voltage of solar panels must be between 200V and 400V.
- For a 380V motor, the total series voltage of solar panels must be between 400V and 700V.
- Solar Panel Power: The total power of several groups of solar panels connected in parallel should be at least 1.2 times larger than the power of the inverter.
- Submersible Pumps: If the water depth of a submersible pump exceeds 30 meters, it is recommended to select an inverter one or two stages larger than typically required, and add a reactor between the inverter and the pump to extend inverter service life.
This device is designed for use by qualified personnel only. All electrical work must comply with local and national electrical codes.

4. Setup and Installation
Proper installation is critical for the safe and efficient operation of the VFD. Ensure all power is disconnected before proceeding with any wiring.
4.1 Mounting
Mount the VFD in a well-ventilated area, away from direct sunlight, excessive dust, moisture, or corrosive gases. Ensure sufficient clearance around the unit for proper airflow and heat dissipation, especially around the cooling fins and fan.

4.2 Wiring Connections
Refer to the terminal block on the VFD for correct wiring. Ensure all connections are secure and properly insulated. Observe polarity for DC input.
- DC Input (Solar Panels): Connect the positive and negative terminals of your solar panel array to the designated DC input terminals on the VFD. Ensure the total voltage of the series-connected panels meets the specified range (200-400V for 220V motors, 400-700V for 380V motors).
- AC Output (Motor): Connect the motor's power leads to the AC output terminals.
- Grounding: Ensure the VFD and motor are properly grounded according to local electrical codes.
⚠ IMPORTANT:
Do not connect both AC and DC power sources simultaneously. This will cause severe damage to the inverter.

7. Troubleshooting
This section provides solutions to common issues you might encounter. For complex problems, contact qualified service personnel.
| Problem | Possible Cause | Solution |
|---|---|---|
| VFD does not power on | No DC input from solar panels; incorrect wiring; faulty solar panels. | Check solar panel connections and output voltage. Verify VFD input wiring. |
| Motor does not start | Incorrect frequency setting; motor wiring issue; VFD in fault state; STOP/RESET button pressed. | Check frequency setting. Verify motor wiring. Press STOP/RESET to clear faults, then RUN. |
| Frequent overload faults | Motor power exceeds VFD capacity; motor running above 50Hz for extended periods; mechanical overload on motor. | Ensure VFD power is greater than motor power. Reduce motor load or operating frequency. Consider a higher capacity VFD. |
| Reduced solar energy conversion rate | DC input voltage not within recommended range. | Adjust solar panel configuration to meet the recommended DC input voltage (200-400V). |
| VFD or solar panel damaged | AC and DC input switches closed simultaneously. | Ensure only one power source (DC from solar) is connected at a time. This damage is typically irreversible. |
