Fault F49 on an XW6848?

Issue:
F49 fault on an XW6848

Product Line:
XW6048, XW4548, XW4024, XW6848+, XW5548+

Environment:
Applications that use the XW or XW+ series inverter/chargers

Cause:
Inverter faults with F49

Resolution:
The F49 is a DC over voltage, this will occur if the battery exceeds(35 VDC) for a 24 Volts and (70 VDC) for a 48 volt system.  This fault will also occur 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.
