I just noticed that several of our sites with Enphase M190s are current limiting at 140 watts. These units used to clip at 199 watts so I feel like our customers just lost a potential 30% of their power output. It appears to be related to a firmware update 520-00008-r01-v01.08.00. We've got one site with just 8 units, 1 of them got this firmware update back in September and has been limiting to 140w since then, 5 of them got this update in late January and have been limiting to 140w since then, the other two are at a previous firmware version and are performing as we would expect up to 199w. Have any of you noticed this same thing? Do you know what this is about? It doesn't feel very fair on the user end of things.
