The maximum power point tracking of the solar cell, the output current is greater than the solar panel current, the real ultra-high efficiency MPPT, supports 8-28V, 100W solar high current charging, it is recommended that each solar panel is equipped with a module) can be expanded in parallel with multiple module charging current.The output voltage can be adjusted arbitrarily, CC-CW automatic control (support single-cell or multi-cell lithium battery, lithium iron phosphate or lead-acid battery, high-power LED, etc.). Battery for full charge management.Dual indication of charging status and charging end status (charging red light / full blue light / red light flashing blue light always means the battery is not connected).Adopt imported high frequency low conductive internal resistance double MOS tube, 10A high current double diode, high efficiency flat high power inductor, constant copper current detection resistor, perfect anti-reverse protection, ultra-low drop, no work, no reverse connection damage charging board.The constant current charge current is set by an external resistor. Low power soft start function.Colour: redMaterial: PCBPackage Contents:1 set * ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
