CHARGE Saves flat batteries from as low as 4V with its unique pulse action. Fastest charge is delivered as ‘smart charge’ control selects pulse or continuous charge according to sunlight strength. Intelligent maintenance continues the next day if the battery retains charge overnight, otherwise the program reverts to OPTIMIZE step. MONITOR Battery condition is displayed every 3 seconds. Ready indication for STD, hi-performance AGM batteries and lithium LFP batteries. Draws less than 0.5mA during monitor mode. Automatically switches to CHARGE when solar power is sufficient. MOUNTING The OptiMate charger-monitor controller is separate to the solar panel and can be placed close to the vehicle or battery so that charge and maintenance progress can be easily followed. The solar panel must be mounted and angled to receive direct sunlight. The reach / distance between battery and panel is 315cm / 124″. To extend, use OptiMate Cable Extenders O-03, O-13, O-23, O-43 or O-53 and insert between the solar panel and the OptiMate charge-monitor controller.
