[RE-wrenches] Outback Mate Controller Issues

[North Texas Renewable Energy Inc]

It's a bit of a long shot but consider that the last solar maximum was in
2000 ad. An 11 year cycle would put us right about in the middle of another
peak. Occasional rogue solar flares, like the one in 1989 that knocked out
the entire Quebec power grid and part of the NW US grid do appear and vanish
within a day or two leaving behind only baffled humans and irate radio
operators.

  Good Morning All......we have recently had 2 off grid outback systems go
haywire.....both have been running perfectly for more than 2 years.....then
all of a sudden the mate stops allowing AC inputs.....a variety of
troubleshooting indicated all components were fine.....Outback support  took
care to help with the confirmation that all the components were
fine......finally with us being stumped, tech support asked us to unplug the
mate from the hub and replug it back in.....Voila!  everything started
working properly again......only setting that seemed to be changed and
needed to be reset was that the chargers on the inverters were turned off
and a few button pushes later and this was also restored......
  Anyone else having any similar experiences?  This is puzzling as we
haven't ever had this kind of problem and for some coincidental reason we
had two systems both with long term smooth operating histories have the same
issue......we appreciated the quick, accessible, competent support from
Outback tech support but remain puzzled as to what may have triggered these
odd events......feedback appreciated!
