I have tested and sold many MPPT models. The Phocos MPPT controller I was evaluating failed and we have had our share of Outback and BZ controller failures. Blue Sky Energy has had a few bad controllers but compared to the volume of BSE products we sell (over 1100) they have been the most reliable.
