Color: 40a; Color scheme: Black and Orange Compact solar charge controller with clear LCD display and multi protective functions. Designed for 12V or 24V battery systems, this controller automatically detects system voltage and manages battery charging in three stages to improve battery life and charging efficiency. The ABS and PC housing provides durable construction in a compact 125 x 112 x 34 mm package. Key benefits Automatic 12V or 24V recognition simplifies installation and eliminates manual mode switching. Three stage charging management with boost, float, and recovery stages helps maintain battery health and reliable startup. Builtin protections against overcurrent, shortcircuit, opencircuit, and reverse connection reduce installation risk and protect connected components. Accurate temperature compensation and automatic voltage correction improve charge accuracy and conversion efficiency. Integrated USB output (5V, up to 2.5A) for charging small devices directly from the controller. What makes it stand out Clear largescreen LCD for straightforward status and setting readouts. Compact and robust ABS plus PC construction for mounting in small enclosures or on vehicles. Wide photovoltaic input allowance for both 12V and 24V systems up to specified maximum PV voltages. Technical specifications Material: ABS and PC Color: Black and Orange Size: 125 x 112 x 34 mm Rated Voltage: 12V / 24V (automatic recognition) Rated Charging Current options: 10A, 20A, 30A Maximum photovoltaic voltage: 23V for 12V battery; 46V for 24V battery Boost charging voltage: 14.4V Floating voltage: 13.7V Discharge cutoff voltage: 10.7V Discharge recovery voltage: 126V Charging recovery voltage: 13V USB output: 5V / 2.5A (maximum) Package includes: 1 pc Solar Charge Controller Builtin protections and control features Overcurrent protection for charging and load circuits Shortcircuit protection for PV and battery connections Opencircuit detection to avoid false operation when input is disconnected Reverse connection protection to prevent damage from incorrect wiring Temperature compensation for automatic correction of charging and discharging voltages Typical applications Small offgrid solar systems for cabins, caravans, and boats where 12V or 24V batteries are used. Solar battery maintenance and charging for standalone lighting, security, or backup power installations. Mobile and portable setups for camping or field work that need a compact controller with USB charging capability. Note Please allow minor measurement variation due to manual measurement. Color appearance may vary slightly depending on display settings.
