[RE-wrenches] Xantrex XW6048 HOT!

[Jason Szumlanski]

It has a Combox and I was able to check the system using the web interface
on the local network. There were no faults at the time I was there, but
there was an OverTemp warning. I have not personally observed it with the
F66 error, so I don't know anything else, but it stands to reason that
eventually the warning reaches the level of a fault/error. I'm going to see
what happens with the Inverter and Charger functions disabled. If it faults
out again, I will just delete it from the system.

Thanks, everyone, for the help. I'll report back if I learn anything else.
