1.HIGH EFFICIENCY- The solar charger controller has the function of Maximum Power Point Tracking. Its efficiency is not less than 99.5% and conversion efficiency up to 98%. It can detect the solar panel's voltage and current in real-time and keep tracking the maximum power point to charge the battery with the maximum power. 2.AUTOMATIC RECOGNITION- The charge controller can automatically identify 12V/24V/36V/48V systems. The full PV input voltage of DC 150V makes it suitable for more PV modules and convenient for users to use in different modes. 3.LCD DISPLAY SCREEN- The solar charge regulator features a high-definition LCD function to support the setting of related parameters, such as system type, PV voltage, charge voltage, charge current, charge power, temperature. It supports the expansion of the WIFI module to realize the app cloud monitoring. 4.INTELLIGENT & PROTECTIVE- The solar controller adopts a built-in intelligent temperature-controlled cooling fan, which effectively reduces the operating temperature; it adds various protection functions such as low-voltage input protection, over-voltage input protection, and over-charging source protection. 5.MULTIPLE APPLICATION- The solar regulator can be widely used in homes, schools, transportation, streets, communication fields, petroleum, marine, meteorological fields, and other solar off-grid power supply systems, such as traffic lights, broadcasting/communication power systems, garden lights, etc. ******************************************************************************************************* *Specifications Color: Red + black Controller type: MPPT (maximum power point tracking) MPPT efficiency: 99.5 % System type: DC12V/24V/36V/48V (automatic recognition) System Voltage and Rated Power 12V system: DC9V-DC15V, 520W 24V system: DC18V-DC30V, 1040W 36V system: DC32V-DC40V, 1560W 48V system: DC42V-DC60V, 2080W Max.
