So if that light on means the alternator is shut down, the only amps coming in are from the solar and batteries. Not many solar amps, so battery will run down but with the house batts also on line, that would take longer.
The solar controller would stay in Bulk but not be able to keep the battery voltage at 14.6 for long. What happens next?
In my test when the charger was removed, the voltage went back down to spec, but the light stayed on. I don't know if the alternator came back on. It did when I restarted.
Pretty simple. When the line voltage drops, the regulator does its job and sends voltage to the rotor winds and the generator goes back to work.
