[RE-wrenches] Xantrex XW6048 HOT!

[Dave Angelini Offgrid Solar]

Yes worrisome. The fault log will show possible causes. The 
troubleshooting guide will tell you too look for black chunks of mosfet 
transistors in the right bay of XW down low. Really rare, but in a hot 
environment 10 years is pretty amazing.

All of the docs are on the Schneider site under XW 120.
