FAQ

What should I do if the power air switch trips after the solar pump inverter is powered on?

When the power air switch trips after the solar pump inverter is powered on, you can follow the steps below to troubleshoot and handle it:

  1. Check the connection between the inverter and the power supply: Make sure that the connection between the inverter and the power supply is firm and there is no looseness or poor contact.
  2. Check whether the inverter is short-circuited: The internal short circuit of the inverter is a common cause of air switch tripping. Check the circuit inside the inverter to see any broken wires or short circuits between wires.
  3. Check whether the inverter is overloaded: When the output power of the inverter exceeds its rated power, the current will increase sharply, causing the air switch to trip. Check whether the inverter is overloaded. Possible reasons include aging of solar panels, bad weather conditions, excessive load, etc. If there is an overload, the load should be reduced appropriately or the inverter output power should be reduced.
  4. Check the input/output voltage: If the inverter's input voltage is too high or the output voltage cannot be adjusted normally, it will also cause internal capacitor overvoltage, thereby causing tripping. Check whether the output voltage of the solar panel is normal and whether the regulation function of the inverter output voltage is normal.
  5. Check the rated current of the air switch: If the solar water pump inverter operating current exceeds the rated current of the air switch for a long time, the air switch will trip. Verify whether the rated current of the air switch matches the current requirements of the inverter and the load. If not, replace the air switch with a higher-rated current.
  6. Check the inverter log and alarm information: If conditions permit, checking the operation log and alarm information of the inverter may help to locate the problem quickly.
  7. Replace the faulty parts: If the above checks are normal, but the problem is still not solved, it may be that some parts inside the inverter are faulty. At this time, you should contact professional maintenance personnel or manufacturers for inspection and replacement of faulty parts if necessary.
  8. Seek professional help: If the above steps cannot solve the problem, it is recommended to contact a professional electrician or inverter manufacturer technician for further diagnosis and repair.

Efficient and stable, perfect choice for solar water pumping
This 37 kW 3-phase solar water pump inverter I bought is amazing! Its efficient energy conversion allows me to easily drive the water pump while utilizing solar energy to maximize energy use. The compact design saves space and is simple to operate, making it easy to install and operate even for non-professionals. I especially like its stability and reliability, which is excellent regardless of the weather conditions. All in all, this inverter not only meets my energy needs, but also allows me to contribute to environmental protection. Highly recommended!
