1、FOR OFF GRID SYSTEMS: The solar charge controller can detect the generating power of the solar panel in real time, and track the highest voltage current value(V1), so that the system can charge the battery with the maximum power output. Applied to the solar off grid photovoltaic system, to coordinate the work of solar panels, batteries and loads, is the core control component of the off grid photovoltaic system 2、LCD DISPLAY: Solar charge controller uses liquid crystal display running state, running parameters, control parameters, etc. Users 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 port 3、PROTECTION FUNCTION AND SYSTEM MAINTENANCE: Solar charge controller with input power limit protection, photovoltaic input terminal voltage is too high, photovoltaic input short circuit protection, photovoltaic input reverse connection protection, load over power protection, load short circuit protection, night prevent reverse charge protection, TVS lightning protection, over temperature protection, can avoid the damage of product components caused by installation errors and system failures to greatest extent 4、DUAL FAN SYSTEM HEAT DISSIPATION: The solar panel regulator has the current limiting charging mode. When the power of the panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power and make it work at the rated charging current 5、WIDELY USED: Solar panel 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. Item Type: MPPT Solar Charge Controller System Voltage: 12V 24V adaptive No Load Loss: ≤0.4W Battery Voltage: 9~32V Maximum Power Point Voltage Range: Battery voltage +2V ~ 100V USB Output: 5V 3A Conversion Efficiency: ≤98% MPPT Tracking Efficiency: >99% Temperature Compensation Coefficient: -2mv/℃/2V(default) Operating Temperature: -10℃-+65℃ Protection Level: IP21 Electromagnetic Compatibility: In line with EN61000, EN55022, EN55024 Altitude: ≤3000meters 1 x MPPT Solar Charge Controller
