INTUITIVE LCD DISPLAY: The solar controller is equipped with a large LCD display to display the status of the battery and solar panels, mode control, load output status and parameter information in real time. This visual interface ensures easy management EFFICIENT CHARGING: Solar charging controller uses an automatic maximum power point tracking (MPPT) charging mechanism to optimal charging efficiency. This maximizes the conversion of power from the solar panel to the battery system HIGH UTILIZATION: The solar panel charging controller can quickly track the maximum power point of the photovoltaic array in any environment, ensuring that the tracking efficiency is not less than 98%. This greatly improves the efficiency of the solar system Item Type: MPPT Solar Charging Controller System Voltage: 12V 24V automatically No Load Loss: ≤0.04A Maximum Input Voltage of Solar Panel: 50V Maximum Charging Current: 20A Maximum Load Current: 20A Maximum Input Power of Solar Panel: 240W 12V, 480W 24V MPPT Tracking Efficiency: ≤99% Temperature Compensation: -2mV/℃/2V(battery) Operating Temperature: -10℃~+65℃ Color: As Shown Material: Plastic+Metal Package Contents: 1*MPPT Solar Charging Controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
