Diversion (Aux Mode) - Alpha Group OutBack Power FLEXmax Series Owner's Manual

Diversion (AUX Mode)

When external DC sources (wind, hydroelectric) are directly connected to a battery bank, any excess
power should be sent to a diversion load, such as a heating element, using a mechanical relay or
solid-state relay.
In Diversion mode, the user programs set points — from -5.0 volts to 5.0 volts relative to the
Absorbing, Float, and EQ voltages — to activate the AUX output. The Diversion AUX mode can be
active (ON) when the battery voltage is raised above one of these set points for a certain amount of
time or inactive (OFF) when it falls below.
 To control a mechanical relay for basic on/off switching of a standard diversion load, follow the instructions
in Figure 25 (both pages).
 To control a solid-state relay for PWM switching and precise control of a load, follow the instructions in
Figure 26 (both pages). This application should not be used with a mechanical relay. It requires the use of a
resistive load and should not be used with other sorts of loads.
For a wiring diagram illustrating how to connect this function, see Figure 27.

IMPORTANT:
If using wind or hydroelectric turbines, keep the
charge controller's diversion voltage slightly
above the Absorbing and Float voltage settings
for efficient functioning.
ON activates the AUX output.
OFF deactivates the AUX output.
AUTO controls the output according to the criteria of the
selected AUX mode.
