This 30A solar charge controller automatically manages solar panels and batteries using a builtin industrial microcontroller. It saves user settings so you do not need to reset it if the battery runs out. The controller supports 12 volt and 24 volt systems and includes dual USB outputs for charging phones, tablets, and laptops at 5V and up to 2.5A. Key benefits Automatic system control: regulates charging and discharging to simplify system operation and reduce manual intervention. Persistent settings: memorizes user parameters so settings remain after deep discharge or power loss. Device charging on the go: dual USB outputs provide convenient 5V/2.5A maximum power for small electronics. Clear status and control: an LCD display shows system data and status and allows mode switching and parameter configuration without extra tools. Improved safety and battery life: builtin intelligent protections help prevent overcurrent, short circuit, reverse connection, low voltage damage, and overcharge, helping to extend battery lifespan and maintain conversion efficiency. Features and specifications Controller rating: 30A System compatibility: 12V and 24V DC systems USB outputs: dual 5V USB with combined maximum current of 2.5A Control unit: industrial microcontroller for reliable automatic management User interface: LCD display for monitoring and configuration Protections: overcurrent, shortcircuit, reverse connection, low voltage, overcharge Practical applications Home solar systems: manage rooftop panels and battery banks for lighting, appliances, and device charging while preserving battery health. Offgrid cabins and remote sites: control charging of battery storage and provide USB power for phones and tablets without frequent manual adjustments. Small commercial or workshop installations: protect batteries and maintain stable charging for equipment and backup power systems. What you will notice in daily use Reduced maintenance because settings are retained after power loss. Easier monitoring and setup through the LCD display. Safer operation thanks to multiple automatic protection functions. Ability to charge small electronics directly from the controller using the dual USB ports. This controller delivers reliable, automatic charging control for small to medium solar systems, with protections and user convenience designed to improve system efficiency and extend battery life.
