Sunny Boy Display Problem [RE-wrenches]

[Kent Sheldon]

Peter, Congratulations troubleshooting the inverter/display. I have seen
this happen before. If the three LED's were on, and behaving normally
(green LED on solid), then the inverter was in fact working. Regards,

Wrenches,
We received an SMA SB2500 with display that was apparently dead before
it
got out of the box.  Nothing happened as we attempted to commence
system.  A
second SB mounted left of it worked fine and had begun its countdown.
We
shut it all down and thought about what to do.  Checked all our stuff
and
started looking at the inverters (covers still off).  We happened to
notice
that the display on the "dead" unit was not mounted properly.  The
display
panel had been installed one row of pins lower than it should have been.
We
remounted the display panel circuit board on to the correct rows of pins
engaging them all--and no problems commencing system normally.  My
question:
Was the inverter "on" when the display wasn't?  So if anyone runs into
similar sitch you might check the display panel alignment before crying
foul
inverter.

That's what I like about solar PV and (solar thermal systems that don't
freeze up) there's always that edge of adrenalin to it--and when it all
works like it's supposed to...that's just heaven.

One heck of a star we have shining for us all too.  Thank God.

Merry Christmas, everyone!

Peter
ASAP POWER!
