1. Solar cell high power point tracking, output current solar panel current, true ultra-high efficiency MPPT, supports 8-28V, solar high current charging within 100W, it is recommended to equip each solar panel with one module) multiple modules can be connected in parallel to expand the charging current 2. The output voltage can be adjusted arbitrarily, CC-CW automatic control (can support single or multiple lithium batteries or lithium iron phosphate or lead-acid batteries, high-power LEDs, etc.) 3. Complete battery charging management 4. PWM switching frequency: 300KHz 5. Constant current charging current is set by external resistors (preset 5000mA/2000MA)<br><br>Trickle charge for deeply discharged batteries Dual indication of charging status and charging end status (red light on when charging/blue light on when full/red light flashing and blue light on when no battery is connected) Low power soft start function high-frequency low conduction internal resistance dual MOS tubes, 10A high current dual diodes, high-efficiency flat high-power inductors, constantan current detection resistors, ultra-low voltage difference anti-reverse connection protection, reverse connection does not work, and reverse connection damage to the charging board is eliminated Color: As shown Material: PCB<br><br>Package Contents: 1 x 5A solar charging panel MPPT<br><br>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.
