System Display-Based Functions
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) feature, which runs through the
entire three-stage charging cycle. It can start according to battery voltage, inverter load, time of day,
and other criteria. It has a quiet time feature which restricts the generator from starting at
inconvenient times. Additional features are also available.
Because this is an advanced function with capabilities beyond the inverter’s
Gen Alert
, the control
logic for AGS is based in the MATE3 system display, not the inverter. See the MATE3 Owner’s Manual
for more information on programming and using the AGS mode.
High Battery Transfer
In High Battery Transfer 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.
In this mode, 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. See the MATE3 Owner’s Manual for more
information.
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.
Because this is a system-wide function and not a function of individual inverters, the control logic for
Grid Use Time is based in the MATE3 system display. See the MATE3 Owner’s Manual for more
information.
