[RE-wrenches] MTBF

[Marv Dargatz]

All,

Mean Time Between Failure (MTBF) is a statistical number that is based 
on failure rates of components in a piece of equipment, under specific 
operating conditions. Numerical analysis, with testing and historical 
data, results in this calculated number.  MTBF can be applied to a 
number of real world mechanisms.  For example, the MTBF of most solar 
modules is on the order of 600 years.  The MTBF of an average American 
30-something year old male is 900 years.  Enphase will shortly be 
publishing a white paper that explains how MTBF ratings are determined 
and gives more details about the MTBF rating of our micro-inverter.

If you would like, I'll post a notification on this list when the paper 
is available.

See Ya!
