Features: 1. LCD Liquid Crystal Display: Large LCD display, support battery working status display, solar panel working status display, mode control display, load output status and each parameter display, normal and fault status display 2. 7 Operation Modes: Charging mode, light control mode, light controlandtime delay control mode, general control mode, manual control mode, timing control mode and test mode, the test mode is only for factory test use 3. 4 types of voltages automatic identification: It will automatically identify DC12V/24V, DC36V, DC48V by itself 5. Large section Wiring Port: use large section, large spacing wiring ports, can be installed with 16mm wire, the wire spacing of 7mm increments of the insulation performance and the correlation of installation, effectively reduce current and voltage drop while reducing losses 6. Dual USB Charging Ports: The solar charge controller options a dual USB charging port design, which can charge two devices at the same time, and supports most of USB port devices, such as mobile phones, tables, PSP game consoles, etc 7. Thickened Aluminum Alloy Heat Sink: The MOS tube is used to lock the heat sink design, the heat distribution is more uniform, and there is no fear of the temperature rise caused by the MOS tube, the powerful heat distribution capacity can operate normally in the environment of 55, at the same time, it is required with functions to prevent overage, overvoltage, DC output low voltage, High voltage protection and reverse polarity protection, etc Specification: Type: Solar Charge Controller Maximum charging current: 100A Maximum input voltage of photovoltaic panels: 15V-23V (12V), 30V-45V (24V), 45V-69V (36V), 60V-90V (48V) Maximum input power of photovoltaic panels: 1000W (12V), 2000W (24V), 3000W (36V), 4000W (48V) Output voltage: DC12V/24V/36V/48V; DC5V/1.5Ax2USB Support Battery: Lithium Batteryandamp;Lead Acid Battery Working temperature: -25-55 Cooling method: heat sink self cooling Charging method: Focused MPPT regulation charging Working mode: Seven Protection function: prevent overage, overvoltage/DC output low voltage, high voltage protection, reverse polarity protection, etc Product size (L x W x H): 195 x 183 x 68mm/7.68 x 7.20 x 2.68inch Package size (L x W x H): 205 x 205 x 70mm/8.07 x 8.07 x 2.76inch Note: Please connect the battery to the controller first, and then the photovoltaic panel to ensure that the battery voltage is higher than (12V battery is higher than 10V; 24V battery is higher than 20V; 36V battery is higher than 30V; 48V battery is higher than 40V), otherwise it will cause voltage identification error Package included: Solar Charge Controller x 1 Manual x 1 Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
