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 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.
