100A MPPT Dual USB Solar Charge Controller 12V 24V 36V 48V Solar Panel Lead Acid Lithium Battery Regulator Stabilizer ChargerProduct Display: Large LCD screen displays the operational status of the battery, solar panel, mode control, load output status, and all parameters, including normal and error statuses. 7 Operating Modes: Charging mode, light control mode, light control + time delay mode, general control mode, manual control mode, timer mode, and test mode (test mode is only for factory testing). Automatic Detection of 4 Voltage Types: Automatically detects DC12V/24V, DC36V, DC48V. Large Cross-Section Cable Connection: Uses large cross-section and large-spacing cable connections, allowing installation of 16mm long cables. The 7mm cable spacing improves insulation performance and installation reliability, effectively reducing current and voltage losses. Dual USB Charging Ports: The solar charger features dual USB charging ports, enabling simultaneous charging of two devices. It supports most devices with USB ports, such as mobile phones, tablets, PSP gaming consoles, etc. Thick Aluminum Alloy Heat Sink: The MOSFET is locked in the heat sink design, providing even heat dissipation and eliminating the risk of temperature rise caused by the MOSFET. The powerful heat dissipation capacity allows it to function normally in environments up to 55°C. It also includes protection against overloading, overvoltage, DC output undervoltage, high voltage, and reverse polarity.Setup Instructions: Clock Setting: After connecting the battery, press "▲" and "▼" to adjust the clock settings and press "■" briefly to save. Charging Voltage Setting: After connecting the battery, setting the clock, and saving, press "▲" for 3-5 seconds. The screen will display LV (maintenance charging voltage), which can be adjusted using "▼". Press "▲" briefly again. HV is for increasing the charging voltage, which can be adjusted using "▼". Press "▲" briefly again. F**V is the undervoltage shutdown voltage for the DC load, which can be adjusted using "▼". After setting, press "▲" for 3-5 seconds to save and exit.
