4.4 Generator/Automatic Generator Control Settings
The battery related settings for using a generator and/or an automatic generator start/stop (AGS)
control with HLX+ batteries can usually be found in the inverter/charger and solar charge controller
settings.
Some generators and/or AGS have settings for 2 minute, 2 hour and 24 hours (or similar duration)
start voltages. They set time limits the battery voltage can sit at before activating the generator.
They are related to the Low Voltage Disconnect/Cut-Off voltage and the Recharge/Re-bulk volt-
age. Expect to adjust any or all of them over time to get exactly the generator behavior you wish.
Depending on the make and model of the generator or AGS, you may need to have more spacing
between these settings.
• 2 minutes - Set just above the inverter/charger Low Voltage Disconnect (12.25 V) so the gen-
erator starts before the inverter stops inverting.
– Start at approx. 12.3 V and adjust as necessary.
• 2 hours - Set above the 2 minutes volts.
– Start at approx. 12.4V.
• 24 hours - Set just below the Recharge/Re-bulk voltage. If the Recharge/Re-bulk setting
hasn’t already started the generator at this time, the generator will start.
– Start at approx. 12.7 V if Recharge/Rebulk is 12.75 V.
