Firmware Updates
IMPORTANT:
All inverters will shut down during firmware updates. If loads need to be run while
updating the firmware, bypass the inverter with a maintenance bypass switch.
Communication cables must remain connected and DC power must remain on.
Interrupted communication will cause the update to fail and the inverter(s) may not work
afterward. Inverters automatically update one at a time beginning with the highest port.
Each requires about 5 minutes.
Updates to the inverter’s internal programming are periodically available at the OutBack website
www.outbackpower.com. If multiple inverters are used in a system, all units must be upgraded at the
same time. All units must be upgraded to the same firmware revision.
IMPORTANT:
All stacked FXR inverters must have the same firmware revision. If multiple stacked
inverters are used with different firmware revisions, any inverter with a revision different
from the master will not function. (See the stacking section on page 43.) The MATE3 will
display the following message:
An inverter firmware mismatch has been detected. Inverters X, Y, Z
2
are disabled. Visit
www.outbackpower.com for current inverter firmware.

The port designations for the mismatched inverters are listed here.
