Question: Roy wants to know... My Apollo gate opener is wired to 110 VAC electric, which in turn is wired to a 12 volt battery. Does the gate open with 110VAC or 12 volt battery? Is the battery necessary if wired to 110VAC?
Answer: Good morning Roy, yes it is necessary, your Apollo is indeed a 12VDC operator and everything runs off of the battery. The 110 VAC is for the trickle charger which keeps your battery charged and conditioned so that your operator can run. You can conceivably replace the electric charger for an SG-4 and a solar panel (or panels, depending on how much use the operator gets) and have a fully solar system.
