Thanks, iPlug!iPlug wrote:Line 183 update.
Prior reported existing system with 28 Suntech 245 Pluto with 28 M215 Enphase microinverters: still no inverter failures.
That brings the MTBF of your M215s up to over 136 years and still you have no failures. That's a very good result for a five-year-old system. My M190-based system (with 42 inverters) had four failures by the time it was that age.
Thanks! Added. Currently, these new M250s reside in row 198. Those M250s are attached to the highest-power PV modules I am tracking. Hopefully they will fair as well as all of the other M250s have.iPlug wrote:System upgraded with additional installation 4/5/17 with 15 LG305 Neon X with 15 M250 Enphase microinverters. No inverter failures. Using same Envoy.
BTW, any chance those M250s are the 72-cell versions? I've noticed quite a few of those kicking around on eBay, so I thought I would ask.
Just so everyone knows, I do not have a great idea of what to do with the Envoy MTBF columns when new inverters have been added to the system. As such, the overall MTBFs calculated for the Envoys are certainly not correct. The good new here is that many of us have had our Envoys operating for over 6 years without any failures. While that tells us nothing about MTBF, it provides a bit of comfort regarding the life of a component which used to come with only a one-year warranty (now five).iPlug wrote:Using same Envoy.
