CHARGE

• Recovers completely discharged batteries from 4V thanks to its unique pulse action. Faster charging – thanks to the smart charge control that selects either pulse or continuous charging based on sunlight intensity. Intelligent maintenance – continues the next day if the battery retains charge overnight; otherwise, the program returns to the OPTIMISATION step.

CONTROL

• The battery status is displayed every 3 seconds. Ready indication for standard, high-performance AGM, and LFP lithium batteries. The control mode consumes less than 0.5 mA. Automatically switches to CHARGE mode when solar energy is sufficient.

MOUNTING

• The OptiMate charge controller is independent of the solar panel and can be placed near the vehicle or battery for easy monitoring of charge and maintenance indications. The solar panel must be mounted and exposed to direct sunlight. The range/distance between the battery and the panel is 315 cm / 124″. To increase this, use OptiMate cable extensions O-03, O-13, or O-23 and insert them between the solar panel and the OptiMate charge controller.
