Configuring the Auxiliary Output

Trigger Source Descriptions
Low Batt Voltage Activates the auxiliary output when the battery voltage falls
below the trigger setting for the trigger delay time. Deactivates the auxiliary
output when the battery voltage rises above the clear setting for the clear delay
time. Use this setting if you want the auxiliary output to control a relay to
disconnect loads from a battery that is nearly discharged, or to activate a low-
battery-voltage alarm such as a buzzer or light.
Hi Batt Voltage Activates the auxiliary output when the battery voltage rises
above the trigger setting for the trigger delay time. Deactivates the auxiliary
output when the battery voltage falls below the clear setting for the clear delay
time. This setting is useful for:
• installations that have another external charging source such as a wind
generator or hydro generator connected directly to the batteries. The solar
charge controller auxiliary output can control a relay to disconnect the
external charging source from the battery when the battery is in danger of
being overcharged, or control a relay to turn on a diversion load.
• activating a high-battery-voltage alarm such as a buzzer or light.
• activating a vent fan to disperse hydrogen from the battery compartment
when the batteries reach their gassing voltage.
Hi Array Voltage Activates the auxiliary output when the PV array voltage rises
above the trigger setting for the trigger delay time. Deactivates the auxiliary
output when the PV array voltage falls below the clear setting for the clear delay
time. Use this setting if you want the auxiliary output to control a series latching
relay to disconnect the PV array from the solar charge controller or trigger an
alarm when the PV array voltage exceeds the trigger setting (the solar charge
controller maximum operating voltage is 140 Vdc).
You can also use the Hi Array Voltage trigger to control a relay to turn on a night
light. Set the Trigger Level to your nominal battery voltage and the Output Mode
to Active Lo. This will energize the relay and turn on the light whenever the array
voltage is insufficient to charge the battery bank.

Sets the mode (polarity) of the
aux output. When Active Hi is
selected, the aux output turns
on when the trigger source is
present. When Active Lo is
selected, the aux output turns
off when the trigger source is
present.
Important: If the selected trigger source is Low Batt Voltage or Hi Batt Voltage,
changing the nominal battery voltage setting will reset the Trigger Voltage Level
and Clear Voltage Level settings to their default values.
