Fault F49 on an XW6848?

 F49 on the XW+ Hybrid Inverter/Charger

The F49 is a DC over voltage, this will occurr if the battery exceeds(35 VDC) for a 24 Volts and (70 VDC) for a 48 volt system.  This fault will also ocurr if the batteries are disconnected while the inverter is operating or if the high battery cut out is set too low.
You can clear the fault and make sure batteries are properly connected as well as setting the HBCO to a value that the battery will not exceed.
