Outback FXR2012A User Manual

Operation
52 900-0167-01-00 Rev A
 When battery voltage rises above a settable high voltage level, the AUX output is activated after a
settable delay. The AUX output controls a larger relay, which allows current to flow from the batteries
to a dedicated AC load when energized. Diversion is usually used to regulate battery charging. The AC
device is usually wired to the output or load panel and must be left on. It must be sized to dissipate all
of the energy from the renewable source if necessary. Diversion will turn off following a delay when a
low DC voltage setting is reached.
 The AUX output will automatically turn on to run the loads if the inverter accepts an AC source.
 Settable parameters include:
 Low and high DC voltage
 On and off delay
 During variable conditions, the AUX output is triggered no more than once per minute (if voltage
conditions are still met). This prevents rapid nuisance cycling of the AC load.
 AC Divert should not be used as the sole source of battery regulation. If the inverter shuts down or fails,
the batteries could suffer severe damage. This function should be supported by an external regulator.
 If the inverter shuts down due to overload, the AUX output will also shut down. If the inverter
load exceeds 30 Aac, the AUX output will turn off to prevent an overload condition.
 If either the FETs or the capacitors (see page 64) become too hot, the AUX will turn off due to
diminished inverter wattage capacity.
Note that even if every function in the menu is set to
Off
, external programming from other devices
may still activate the AUX output. An example is the system display’s AGS function. See page 53.
The AUX functions are summarized in Table 5.
