Feature 1 MPPT Technology: Advanced MPPT power point tracking technology, with maximum tracking efficiency of 98%, effectively saving battery panel energy. 2 Digital Display: 4 digit digital tube display design, real time display of battery panel voltage, charging current, battery voltage, etc., clear and intuitive. 3 Energy Saving: Solar panel power technology, low standby power consumption, system power consumption is all from the panel, does not work at night. 4 Safe Operation: Equipped with a child lock function to prevent wrong charging caused by touching the button by mistake and provide good protection. 5 Applicable Battery: Used for lithium battery, lithium iron battery, acid battery, etc. (battery voltage 48V 60V 72V), users can set parameters through the SET key. 6 High Efficiency: Ultra fast maximum power point tracking speed, while ensuring tracking efficiency, wide photovoltaic array operates at the maximum power point.Item Type: Solar Boost ControllerMaterial: Aluminum AlloyOvervoltage: 57.6V (48V), 72.0V (60V), 86.4V (72V), self settingPower: 600WSolar Input Voltage Range: 26-63V (the voltage of the solar panel needs to be lower than the battery voltage)MPPT Voltage Range: 26-63VReverse Connection Protection: The reverse connection of the battery will blow the fuseMPPT Efficiency: 99%Overall Efficiency: 95%Working Temperature: -35-65Insulation Resistance: AC1KV, 5min test 20MWaterproof Grade: IP54 Package List1 x Solar Boost Charge Controller1 x Fuse1 x User ManualNoteThe mains charger does not need to be changed. The solar charger is directly connected to the battery. The 2 charging methods do not affect, and can be charged at the same time; The mains charging will not flow back to the controller; The input end of the solar controller must be connected to the solar panel to charge the battery, and the motor cannot be directly driven.
