Dual USB LCD Display Solar Charge Controller 12V 24V Solar Panel Battery Controller Charger Regulator with Power-off Memory Function Feature: 1. Adopt industrial-grade main control chip. 2. Large-screen LCD display; display of charging and discharging current; query of accumulated power generation and discharge; temperature display; light control + delay control; adjustable charging and discharging parameters; with functions such as power-off memory. 3. Dual USB output, maximum current up to 2.5A, support for iPhone charging. 4. Complete 3-stage charging management 5. Built-in over-current, short-circuit protection, open-circuit protection, reverse connection protection, all of which are self-healing and do not damage the controller. 6. Anti-backflow circuit, ultra-low heat generation Specification: Material: ABS + PC System voltage: 12V24V automatic adaptation Rated charging current (optional): 10A/20A/30A Maximum photovoltaic voltage: 23V for 12V battery; 46V for 24V battery Boost charging voltage: 14.4V Floating voltage: 13.7V (default value, adjustable) Discharge cut-off voltage: 10.7V (default value, adjustable) Discharge recovery voltage: 126V (default value, adjustable) Charging recovery voltage: 13V Light-controlled turn-on threshold Photovoltaic panel: 8V (light-controlled turn-on has a delay) USB output: 2 USB outputs, 5V/2.5A (maximum) Standby current: <10mA Working temperature: -35 - +60℃ Size: 125x112x34mm/4.92x4.41x1.34in Recommendations for safe use: 1. This controller automatically recognizes 12V24V. When installing for the first time, please make sure that the battery has enough voltage so that the controller can recognize the correct battery type. 2. Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment. 3. This controller is only suitable for all kinds of lead-acid batteries (including openings, seals, gels, etc.). 4. This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source. 5. The controller will heat up when it is running, please pay attention to install the controller on a flat, well-ventilated surface. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3cm measuring deviation due to manual measurement.
