Well that is another question I suppose. I have the VSR set to turn on at 12.7 volts and off again at 12.4 volts with a 2 minute wait before switching off (or something like that - but switch on again is instant). It also has a remote over ride which I use when charging from the rear. I have not done any logging on long drives to see how often the charging system drops below 12.4 volts but as the VSR is connected to the battery i thought these settings should be OK.
I do have a secondary question about the breaker size to use at both ends. I have 50 amp breakers at present so is that adequate for the expected charging currents if connected directly?
