30A 12V/24V PWM Solar Charge Controller, Dual 5V USB Output, Regulator with LCD Screen for Lead-Acid Batteries (30A)

【Large LCD Screen】: The charge controller features a screen displaying the charge and discharge current, cumulative energy production, discharged power, and lighting duration. It offers adjustable charge and discharge parameters, a power outage memory function, and other features. 【Dual USB Output】: Solar charge controller with a maximum output of 5V/2.1A. Built-in protections against short circuits, open circuits, reverse polarity, overload, reverse current, and overheating. In case of a fault, the controller automatically resets. 【Visual Observation】: The device's various states are easy and intuitive to observe. While the solar panel is charging, the arrow between the solar panel icon and the battery icon flashes rapidly; Once the battery is charged, it flashes slowly and charging stops. 【Protection Function】: The solar charge controller protects the battery from overcharging and over-discharging. It can be used to charge lamps and mobile phones that operate on DC power (be sure to connect the positive and negative terminals correctly and ensure all connections are tight). 【Easy Installation】: Featuring a 5.5 x 2.1 mm DC interface, it connects directly to a portable, foldable solar panel. This DC interface provides a 12V charge, simplifying installation.
