Robust PWM solar charge controller with automatic voltage adjustment (12 V or 24 V battery systems). The controller features an integrated graphic LCD to display charge status, voltage, and operation menus – user-friendly via buttons. A three-stage charging algorithm with temperature compensation ensures optimal battery charging and protection against discharge, along with timely equalization charging. Protection functions include overcharge, deep discharge, overload, short circuit, and lightning protection (TVS). Ideal for demanding off-grid applications. Ready for shipment within 24 hours after payment receipt.
