Feature:1. FOR OFF GRID PHOTOVOLTAIC SYSTEMS: Solar charge controller can detect the power generation of solar panels in real time, and track the highest voltage current value(V1), so that the system can charge the battery at the maximum power output. Used in solar off grid photovoltaic system, coordinate the work of solar panels, batteries and loads, which is the core control component of off grid photovoltaic system2. LCD DISPLAY: MPPT solar charge controller use LCD liquid crystal display operating status, operating parameters, control parameters, etc. The user can easily check the parameters by pressing the button, and can modify the control parameters according to the need to adapt to different system requirements. With 5V 3A dual USB port3. PROTECTION FUNCTIONS AND SYSTEM MAINTENANCE: Solar charge controller with input power limit protection, too high photovoltaic input terminal voltage, photovoltaic input, end short circuit protection, photovoltaic input reverse protection, load overpower protection, load short circuit protection, night prevent backcharge protection, TVS thunder protection, overtemperature protection, To minimize damage to product components due to installation errors and system failures4. DUAL FAN SYSTEM HEAT DISSIPATION: Solar charge controller regulator has a current limiting charging mode, when the panel power is too large, the charging current is greater than the rated current, the controller automatically reduce the charging power, so that work at the rated charging current5. WIDELY USED: Solar charge controller regulator support colloidal battery, sealed battery, open battery, lithium battery and other different types of battery charging procedures. Can be used in household photovoltaic power generation system, communication base station system, highway intelligent monitoring system, landscape lighting project, etc.Specification:Item Type: MPPT Solar Charge ControllerSystem Voltage: 12V 24V AUTONo Load Loss: 0.4WMaximum Solar Input Voltage: 50V VOCBattery Voltage: 9~32VMaximum Power Point Voltage Range: Battery voltage +2V to 50VUSB Output: 5V 3AConversion Efficiency: 98%MPPT Tracking Efficiency: >99%Temperature Compensation Coefficient: -2mv//2V(default)Operating Temperature: -10-+65Protection Level: IP21Electromagnetic Compatibility: EN61000, EN55022, EN55024Altitude: 3000meterSize(LxWxH): Approx. 135 x 135 x 54mm / 5.31 x 5.31 x 2.13in.Package List:1 x MPPT Solar Charge Controller4 x Installation Screws4 x Wall Plugs1 x User Manual
