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.)
Either set of A
UX
The specific choice of R
Different examples are illustrated in the Radian Series Inverter/Charger Installation Manual.
The A output will activate to start the generator when the battery voltage falls to a low set point
UX
for a settable delay. The A
voltage rises to a high voltage setting for a settable delay period.
Settable 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) function that is found in the
system display. For many users, the AGS function 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.
NOTE: Gen Alert is the default selection for the R
IMPORTANT:
When using Gen Alert (or AGS), the generator must be connected to the inverter's G

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.
Vent Fan activates the A
small fan to ventilate the battery compartment to eliminate gases that result from battery charging.
(This is illustrated in the Radian Series Inverter/Charger Installation Manual.) When the voltage falls
below this set point for a settable delay period, the A
Settable parameters include:
High DC voltage

Cool Fan activates the A
intended to trigger a small external fan for additional cooling. See the Warning Troubleshooting
table on page 52 for a description of the fan criteria.
This function does not have settable parameters.
DC Divert activates the A
as a resistor, a heater, or a fuel cell. This prevents overcharging of the batteries. This function can
serve as rough charge regulation for an external charging source.
When battery voltage rises above a settable high voltage level, the A
