System Display-Based Functions
A system display such as the OutBack MATE3 can provide functions not available in the Radian
inverter. These functions are briefly described to provide a better idea of overall system capabilities.
See the MATE3 System Display and Controller Owner’s Manual for more information on all functions.
The system display must be present for these functions to operate. If a function is set up (or already in
operation) but the system display is removed, the function will not operate.
Advanced Generator Start (AGS)
As noted under the
Gen Alert feature (see page 31), the system is capable of starting a generator.
Gen Alert simply starts and stops the generator based on battery voltage. For more advanced control,
the inverter system can use the Advanced Generator Start (AGS) function, which runs through the
entire three-stage charging cycle. It can start according to battery voltage, inverter load, time of day,
and other criteria. AGS has a quiet time application which restricts the generator from starting at
inconvenient times. Additional applications are also available.
IMPORTANT:
This function is higher-priority than
Gen Alert or any other inverter function. It can
activate the 12V AUX or RELAY AUX even if the inverter has disabled them. When AGS is
in use,
Gen Alert and other AUX functions should be disabled on that AUX output to
avoid programming conflicts.
High Battery Transfer (HBX)
In HBX mode, the system is connected to an AC source such as the utility grid; however, it will use
battery power as the first priority. The AC source is locked out until needed.
The system runs on battery-supplied power for as long as the batteries can be sustained. It is
expected that the system will be supplied by renewable sources such as PV power. When the
batteries become depleted, the system reconnects to the AC source to operate the loads.
The batteries may be recharged during this time using the renewable source. When the batteries are
recharged to a high enough voltage, the system transfers back to the batteries as the primary source
(hence the name High Battery Transfer).
NOTE: The inverter’s charger should be off. High Battery Transfer mode is intended to use only the
renewable source for charging batteries. Renewable charging is the motivator for returning to battery
(and renewable) operation. Use of the inverter’s charger interferes with this priority. It also may not
charge effectively.
This mode has similar priorities to the
Mini Grid input mode contained within the Radian inverter.
Either mode may achieve similar results, but they are not identical. See page 14 for the advantages
and disadvantages of each mode.
Because this is a system-wide function and not a function of individual inverters, the control logic for
High Battery Transfer is based in the MATE3 system display.
