Operation

Gen Alert is used as a controller for an AC generator with a remote start feature, although it has limited functionality. (The generator recharges batteries using the inverter’s battery charger.) When the battery voltage falls to a low set point for a settable delay, the AUX output is activated. The AUX output is used to energize a relay. The relay contacts then activate the remote start/stop circuit on the generator. This is illustrated in the Radian Series Inverter/Charger Installation Manual.) The AUX output will be deactivated once the battery voltage rises to a high voltage setting for a settable delay period.

Parameters include:

∼Low and high DC voltage

∼On and off delay

Gen Alert control logic is located in the inverter. It has the advantage of functioning when the system display is removed. However, it may not completely charge the batteries and does not have all the advantages of the Advanced Generator Start (AGS) feature that is found in the system display. For many users, the AGS feature may prove more useful than Gen Alert. Gen Alert, however, could be used as a literal “Generator Alert”, a signal to the user to manually start a generator.

Fault enables the AUX output when the inverter shuts down due to an error condition (see page 39). It can activate a light or alarm to show that the inverter has failed. With the appropriate devices, it could send an alarm signal through a radio, pager, or telephone dialer.

∼This function does not have settable parameters.

∼This function is not triggered by the Phase Loss error, as that error does not shut down the inverter.

Vent Fan enables the AUX output in response to a high DC (battery) voltage set point. It can run a small fan to ventilate the battery compartment to eliminate gases that result from battery charging. When the voltage falls below this set point for a settable delay period, the AUX output turns off.

Parameters include:

∼High DC voltage

∼Off delay

Cool Fan enables the AUX output when the inverter reaches a high internal temperature. It is intended to trigger a small external fan for additional cooling. See the Warning Troubleshooting table on page 40 for a description of the fan criteria.

∼This function does not have settable parameters.

DC Divert enables the AUX output to divert excess renewable energy to a DC load, such as a resistor, a heater, or a fuel cell. 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 DC load when energized. (This is illustrated in the Radian Series Inverter/Charger Installation Manual.) Diversion is activated by high DC voltage and is usually used to regulate battery charging. The resistor 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.

Parameters include:

∼Low and high DC voltage

∼On and off delay

IEEE enables the AUX function as an alert that the utility grid does not meet IEEE parameters for the grid-interactive function (see page 46). It can activate a light or alarm to show that the grid-interactive function has shut down and that there may be problems with the grid. The AUX output will cycle on and off if IEEE parameters are met and the IEEE timer is counting down.

∼This function does not have settable parameters.
