Operation

Auxiliary Terminals

The inverter’s AUX terminals provide a 12 Vdc output that can deliver up to 0.7 Adc to control external loads. The AUX LED (see page 11) illuminates when this output is present. Typical loads include signaling a generator to start, sending a fault alarm signal, or running a small fan to cool the inverter. See the International Series GFX Installation Manual for more information on hooking up the AUX terminals. See the system display manual for instructions on programming this feature.

The inverter has a series of automatic AUX functions built into it which are accessed using the system display. The system display and other devices also have programming, such as AGS, that can control the AUX output. To avoid conflicts, this menu should be turned off when the AGS function is active. (See page 30.)

There are nine functions, each geared toward a different application. They may not appear in the same order as shown here.

¾Cool Fan activates the AUX output when the inverter reaches a high internal temperature. It is intended to operate a small external fan for additional cooling. This is the default setting. See the Warning Troubleshooting table on page 37 for a description of the fan criteria.

∼This function does not have settable parameters.

¾DivertDC activates the AUX output to divert excess renewable energy to a DC load, such as a resistor, a heater, or a fuel cell. When battery output rises above a settable high voltage level, the AUX output is activated after a settable delay. The AUX output operates a larger relay, which allows current to flow from the batteries to a dedicated DC load when energized. (This is illustrated in the International Series GFX Installation Manual.) Diversion is usually used to regulate battery charging. The resistor must be sized to dissipate all of the energy from the renewable source if necessary.

∼DivertDC and DivertAC use the same settable DC voltage and time parameters.

¾DivertAC activates 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 operates 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 deactivate following a delay when a low DC voltage setting is reached.

∼Divert AC and Divert DC use the same settable DC voltage and time parameters.

∼During variable conditions, the AUX output is activated no more than once per minute. This prevents rapid nuisance cycling of the AC load in the event of rapidly changing conditions.

Divert AC 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 deactivate. If the inverter load exceeds 12.5 Aac, the AUX output will deactivate to prevent an overload condition.

∼If either the FETs or the capacitors (see page 37) become too hot, the AUX will deactivate due to diminished inverter wattage capacity.

¾AC Drop activates the AUX output whenever the inverter disconnects from an AC source. It can activate a light (or alarm) to show that the utility grid has failed or that a generator has shut off. Alternately, it could be used to show that the source is operating.

∼This function does not have settable parameters.

¾Vent Fan activates the AUX output in response to high battery voltage. It can run a small fan to ventilate the battery compartment to eliminate gases that result from battery charging. Vent Fan runs for one minute. It then stops for a delay period before running again for another minute.

∼This function has settable DC voltage and settable time delay parameters.
