    I have used this product for over 2 years and have nothing but the best to say about the product. The pump has worked without a glitch. The only complaint I would have is with regards to the lack of detailed installation instructions, or batteries installation for night time or when no sun and no manual for understanding the control box’s operations and it’s capabilities. I did have an issue with lightning burning the box. I called and spoke with support. His service and willingness to help was impeccable. Great job. I would recommend this product to anyone looking at going off-grid any day. The system has helped me disconnect the well from the house, avoiding having to use power from the solar system in the house. 100% recommended!!!

    I installed the pump, control box and solar panels myself. It was a bit of stretch for me, but the Tuhorse agent was most helpful and kept me from screwing things up. It all works as advertised, for now, and the true value of the pump will reveal itself over time. I am very happy right with my system right now and it is fullfilling my expectations
