Operation

Source Status enables the AUX output whenever the inverter accepts an AC source. It can activate a light or alarm to show that the utility grid is present or that a generator has started. Alternately, it could be used to show that the source has disconnected.

∼This function does not have settable parameters.

AC Divert enables the AUX output to divert excess renewable energy to an AC load, usually an AC device powered by the inverter itself. 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 activated by high DC voltage following a delay. This function 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.

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 in the event of rapidly changing conditions.

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 40) 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, the AUX output may still be triggered by an external function such as AGS (see page 32).
