[RE-wrenches] Xantrex XW6048 (quad) blowing past setpoints

[John Blittersdorf]

Jason.
I had that problem with an older XW and problem was corrupted firmware.  It
took many years to get Schneider to admit that the problem was not my
installation or programming.
New firmware fixed a nagging problem of runaway voltage and destroyed
batteries. I also had found that resetting to factory defaults was causing
some of the problem as the default for absorb was 6 hours instead of the
one hour I or less that it should have been.  Found that problem by
resetting to factory defaults and then checking every setting. With the bad
firmware I was seeing the charge rate and voltage setpoints totally ignored
and saw battery go up to 67 volts!
