12V/24V - 20A - PWM SOLAR CHARGE CONTROLLER - DOUBLE BATTERY
UNISOLAR 20.24D converts the electrical power from your solar module into charging current for your battery.
UNISOLAR controllers incorporate a unique 6-step charging algorithm, Algoteck 6, which tests your battery, charges it at 100%, desulfates it, delaminates it, maintains its charge and improves its lifetime while taking into account the ambient temperature to adjust its voltage thresholds according to the recommendations of the battery manufacturers (integrated temperature sensor).
Its 2 outputs allow to recharge up to 2 batteries at the same time and independently. Option: the Unisolar 20.24 D can be equipped with a remote display (Unisolar RM)
