What should I do if there is a problem with the TPON water pump I purchased?

If you encounter after-sales problems of TPON solar well pump kit, please contact me as soon as possible and take a video and photo of the water pump and controller for me. I will send the video and controller to our engineer for viewing, and our engineer will tell you how to pass Commissioning returns the pump to normal operation. If the pump part or controller is damaged, we will send you new parts free of charge.
