Kurt,
You should be able to use Xantrex' tech support on this. I dunno if Brian
Dybvig is still at Xantrex in tech support; he was pretty sharp. Also Ken
Ripley, who is still there. Both have been able to answer my SW tech
questions well over the years.

As only a diagnostic step, go to the last menu heading (19?) in the setup
menu, and then hit red and green buttons simultaneously; there's a tech menu
that isn't explained to us, but one item in there is fan speed, 1-4. That'll
tell you whether it's a software issue, or the fan or thermostat itself, I
would venture.

One of our systems installed back in 98 or 99 that has an original SW in
a grid-tie with battery back-up has a new development.  It seems to be
working okay although now the fan runs continuous and at high speed,
even though there is little load or production on the inverter.

Can anyone tell me if the fan uses software or just a simple temperature
sensor to operate the fan?  Also, if we decide to fix it, is this
something that is easily field serviceable.  It probably uses a pretty
small amount of energy but noise is also an issue for this customer.
