The AGS module I put in a couple years ago has no pots or knobs, it is pure digital.
That's why I had to upgrade to the -arc control panel.
The "down to a certain voltage" setting did not do much for me. As an example, even with fully charged batteries, running the microwave (DW heating her cup of tea) my coffee maker, and a blow dryer, will have the inverter pulling near 100 amps from the batteries, and the voltage will drop down to 10 volts or so, for as long as all three loads are on.
And the AGS (which I've set for 11 volts) will start the genny (without a real need to do so)
With the system set to trigger off a 50% state of charge from the BMK, I can fully load the inverter for 5-10 minutes and the genny won't start (unless of course the batteries actually go below 50% state of charge.)
