_____ From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Marco Mangelsdorf Sent: Thursday, November 03, 2011 2:27 PM To: 'RE-wrenches' Subject: [RE-wrenches] under performing Enphase inverters For the first time, several weeks ago, after 40-50 Enphase installs, we've come across at least two M210s that we putting out consistently lower outputs than their immediate neighbors. We replaced the two mods first, which made no difference. Then, in consultation with Enphase, replaced the M210s. After replacing them, the power output was as it should be. Now I've got another suspect system with several underperforming mods out of (36). Has anyone else had this experience? Thanks, marco
