There were some bumpy roads with the M-190s. Their M-215 and M-250 product were a marked improvement with failure rates far lower than their prior iteration. Since the IQ line was released failure rates have completely stopped. We have installed over 2,000 installations over the years with nearly every inverter on the market (SMA, Fronius, Solar Edge, Outback, Solis, APS, Enphase, HiQ, Eltek, Solectria, ExcelTech, etc etc etc). Enphase has by far been the most consistent inverter choice with the best value per cost by a long shot. Their tech support used to be poor. In 2018/2019 they revamped their customer support/RMA processes (only know this due to spotty failures of old M-215/M-250 products) and this process has been FAR superior to any other inverter manufacturer on the market. Thank you Enphase for understanding the value in customer support, quality manufacturing, and module level performance optimization.
