Refer to the system display literature for programming instructions and menus.
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 Port 1. Each requires about 5 minutes.
Updates to the Radian’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 Radian 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 35.) The system display will
show 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.
See the system display
Overview Guide
for instructions on performing updates.
NOTE:
The MATE3s system display must be used when upgrading the inverter to firmware
revision 001.006.063 or higher.
