LVD1 Circuit Extensions

It is easy to invert the logic of the LVD1 output circuit, this can be useful if you want to automatically activate an AC-operated battery charger or a backup generator when your battery gets low. The above circuit shows the modification to the LVD1 schematic for inverting the output logic. The LVD1 load connection can drive an AC-output solid state relay to switch on power to a backup AC-operated charger, a DC-output solid state relay can be used to control a generator starter circuit. The AC charger should be tested to see if its DC output connection consumes reverse current from the system battery when the charger is off. If this occurs, a suitably rated Schottky diode should be put between the AC charger's output terminals and the battery to prevent the reverse current from discharging the battery.
