Always-available power supplies – usable all year round

EFOY acts as a battery charger

Your EFOY will charge a battery fully automatically. The integrated charge regulator constantly monitors the charging status of a 12 V battery. If necessary, the EFOY can start automatically and switch itself off again when the battery is full. This means that you not only have a constantly full supply of energy, but your batteries also last much longer, since continuous charging protects them against harmful deep discharging.
