Thanks, SurfHawk! Updated.SurfHawk wrote:Row 221 still going strong with no failures on my 12x S280 inverters.
That brings the total number of device-years for all S280s up to 86 with no known failures. So far so good!
The M250s are the current MTBF leaders. They are approaching 400 years with no known failures. The oldest units are nearly four years old. By that point, many M190s were already starting to fail.
pclifton has told me separately that he has a friend who owns many M215s as well as many M250s. He reports that quite a few M215s have failed, but only one M250. Unfortunately, I am unable to add that data into my database since I do not have any visibility of it. It's fine, since we are accumulating more and more data as time goes on.
