5500Watt Solar Pump Inverter

SPC-5K5 Solar Pump Inverter

Connecting a solar pump inverter requires certain steps to ensure normal operation of the equipment and to avoid damage. The following are typical connection steps and precautions:

1. Check equipment and tools

- Check the equipment: Check that the inverter, solar panel, water pump, cables and other accessories are complete.

- Prepare tools: screwdriver, multimeter, cable crimping tool, etc.

- Read the manual: Read the solar pump inverter and water pump manuals in detail.

2. Connect the solar panels

- Series or parallel connection: Depending on the input requirements of the inverter, connect the solar panels in series or parallel to ensure that the output voltage and power meet the inverter specifications.

- Connect to the input: Connect the positive (+) and negative (-) poles of the solar panel to the DC input of the inverter.

- Connect the positive pole to the "PV+" terminal.

- Connect the negative pole to the "PV-" terminal.

3. Connect the water pump

- Adjust voltage and frequency: Ensure that the rated voltage and frequency of the water pump match the inverter output.

- Connect to the output: Connect the power cable of the pump to the AC output of the inverter:
- Single-phase pump: Connect terminals "U" and "N" or "L".
- Three-phase pump: Connect terminals "U", "V" and "W".

4. Grounding
- Inverter grounding: Connect the inverter earth terminal (marked "⏚" or "PE") to the earth wire for safety.
- Pump grounding: Connect the ground terminal of the pump to the ground wire.

5. Installing sensors (optional)
If the inverter supports water level or pressure sensors, you can connect the sensors to the appropriate ports for automatic control.
