MPPT DC-DC Buck Converter 18V Solar Panel Controller Photovoltaic Charging Module Buck Voltage Regulator for Street Light Batteries

Specification: - Product name: MPPT solar charging panel

- Input voltage: DC 8-28V

- Output voltage: DC 5-26V infinitely adjustable

- Output current: 5A - Power: 100W - Charging indicator: Yes. Rapid charging red light is on for a long time, fully charged red and blue lights flash alternately. Full automatic stop - MPPT function: Yes, MPPT maximum power automatic tracking function, can maximize the full use of solar charging - Minimum voltage difference: 1V (because it is a buck regulator module, the input voltage should be at least 1V higher than the output) - Ultra-low power consumption: Yes. Adopt ultra-low dropout design to achieve low power consumption and higher conversion efficiency, designed specifically for solar panels.. - Operating temperature: industrial grade (-40°C to +85°C) - Load Adjustment Ratio: Std. 1% - Voltage Adjustment: -0.5% - Conversion efficiency: Max: 93% Peak: 95% Varies with different light conditions. - Charging mode: Fully automatic intelligent three-stage charging mode. Self-tracking solar power automatically adjusts the charging current size - No-load current: 3mA Even the weak sunlight in the morning can easily start automatically, eliminating the need for manual switching. - Input reverse connection protection: Yes, MOS tube ultra-low voltage difference anti-reverse connection protection, input reverse connection does not work. - Output reverse current protection: Yes. Effectively prevent the battery from flowing back to the charging board at night. - Wiring mode: with terminals - MPPT voltage: arbitrary adjustable, different solar modules MPPT voltage is different. Low power consumption design program, reduce voltage loss, MPPT function can effectively prevent the solar panel voltage by the battery dragged to death and thus slow charging - Module nature: with real MPPT solar maximum power tracking function, fully automatic intelligent charging management, low power consumption - Size: 5.2*3.7*2.2cm
