Radian Series
Inverter/Charger Service Instructions
Purpose and Scope
These instructions detail how to replace the following parts of a Radian Series Inverter/Charger.
PCBA Module (SPARE-200, SPARE-202 and SPARE-204):
The PCBA Module is a set of circuit boards that allows
connection of the AC wires, MATE3, Auxiliary, and Remote Temperature Sensor (RTS) cables as well as connection to
the Power Module. They are pre-assembled for simple drop-in replacement. These circuit boards include the
power supply, control, voltage/current sense, and AC boards along with a mounting plate.
Power Module (SPARE-201, SPARE-203 and SPARE-205):
The Power Module is a set of parts that allow
connection to the battery and connection to the PCBA Module. It is pre-assembled for simple drop-in
replacement. Either module consists of the power transformer, FET board, and related interconnect components
within one chassis.
IMPORTANT: Back up (SAVE) the Configuration on the MATE3
Use the MATE3 to save the existing configuration file of the inverter that is to be repaired
to an SD card. (If there are multiple inverters in the configuration, the configuration file
will back up each inverter’s settings.) Also record the firmware revision and Stack Phase
settings of the inverter(s). If replacing the PCBA Module, performing these tasks will be
helpful to return the inverter to its previous operational parameters. See the
MATE3 System
Display and Controller Operator’s Manual
for details.
IMPORTANT: MATE3 Upgrade
When replacing the PCBA Module, make certain to upgrade the MATE3 firmware to the
latest revision. If it is not upgraded, the MATE3 may not recognize any new inverter
functions. This will make them inaccessible to the user. See the OutBack website,
or AOE website www.alpha-outback-energy.com
, for the
latest firmware revisions.
Power Down
Power down and disconnect all power sources from the Radian inverter prior to replacement of internal
parts. Use the inverter bypass if available and turn off all circuit breakers connected to the inverter.
AC output circuit breaker
Grid AC input circuit breaker
Generator AC input circuit breaker
DC circuit breakers
Generator start circuit
Once these connections are turned off, verify with a voltmeter that NO voltage is present at the DC+ to DC–
terminals (see Figure 1).
WARNING: Shock Hazard and Equipment Damage
It may take time for internal capacitance to fully discharge. Ensure full discharge for at
least one minute (less than 1 Vdc) prior to continuing. If the ribbon cables (see Figure 4)
are removed prematurely, the Radian’s capacitors will retain a sizable charge, which can
cause electrical shock or severe equipment damage during normal handling. This
damage is not covered under the unit’s warranty.
