Grid-Tie Mode
IMPORTANT:
Grid-Tie Mode requires a grid-interactive inverter model (also known as grid-
tied or grid-tie enabled). Not all inverters are grid-interactive. If the MATE3 is
connected to an inverter that is not grid-interactive, Grid-Tie Mode will not
function if selected.
This menu allows the charge controller to work more effectively with any grid-interactive inverters present
on the HUB. When enabled, this setting automatically raises the charge controller’s Float voltage to equal
its Absorption voltage. Since the inverter sells power to maintain its own Float, Absorption, or Sell settings
(all of which should be lower than those of the controller), this mode makes it easier for the inverter to
sell power.
NOTE:
The charge controller’s Float voltage returns to normal any time the inverter enters
PassThru
or
Silent
modes. (See page
35
40 for inverter modes.)

Auxiliary Output on the Charge Controller
This menu controls the output and functionality of the Auxiliary (AUX) output. The charge controller’s
AUX terminals provide a 12 Vdc output that can deliver up to 0.2 Adc to control external loads. Typical
loads include signaling a generator to start, sending a fault alarm signal, or running a small fan to cool the
inverter. See the charge controller Owner’s Manual for more information on hooking up the
AUX terminals.

Set Points:
Status
– The
Auxiliary Output
status is controlled by the <Off>,
<Auto>, and <On> soft keys.
~ <On > activates the
Auxiliary Output
immediately. It will
display the message
Manual On
and remain continuously
active until <Off> is selected.
~ <Auto> sets the
Auxiliary Output
to be triggered by
automatic criteria, according to the option selected in Aux
Mode. When triggered, it displays the message
Auto On
;
otherwise it displays
Auto Off
.
~ <Off> disables the
Auxiliary Output
and prevents any of the
charge controller’s automatic AUX options from working. When
<Off> is selected, it will display
Manual Off
. Note that even if
the AUX output is set to
Off
, it may still be triggered by an
external option not based in the charge controller, such as AGS.
(See page 3105.)
