Features 1、MPPT Charging: This solar charge controller can detect the power generation of solar panels in real time and follow the highest voltage and current value V1, enabling the system to charge the battery at maximum power output. Applied in solar off grid photovoltaic systems, coordinating the work of solar panels, batteries, and loads is the core control component of off grid photovoltaic systems. 2、Clear Display: Using LCD to display operating status, operating parameters, control parameters, etc. You can easily access various parameters through buttons and modify control parameters as needed to adapt to different system requirements. With 5V 3A dual USB interface. 3、Higher Safety: Designed to have input power limiting protection, photovoltaic input terminal high voltage, and so on, which can minimize damage to components due to installation errors and system failures. 4、Stable in Use: Equipped with current limiting charging mode, when the battery board power is too high and the charging current exceeds the rated current, the controller automatically reduces the charging power to operate at the rated charging current. 5、Wider Utility: Support charging programs for different types of batteries, such as gel batteries, sealed batteries, open cell batteries, and lithium batteries. Can be used in household photovoltaic power generation systems, communication base station systems, highway intelligent monitoring systems, landscape lighting engineering, etc. Specification Item Type: Solar Charge Controller System Voltage: 12V 24V Adaptive No Load Loss: ≤ 0.4W Solar Energy Maximum Input Voltage: 100V VOC 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 value.
