Grid Use Time
The inverter system is capable of connecting to, or disconnecting from, the utility grid based on time
of day. It can also be programmed to connect at different times on weekdays and on weekends.
Load Grid Transfer
The inverter system is capable of connecting to, or disconnecting from, the utility grid based on load
size. This avoids undesirable battery discharge from excessive loads. It can also be programmed to
connect to the grid when the batteries reach a low voltage due to excessive discharge.

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 39.) The MATE3 will
display the following message:
An inverter firmware mismatch has been detected. Inverters X, Y, Z

are disabled. Visit
www.outbackpower.com for current inverter firmware.
