Features:

1. The input and output terminals are made of high-side switching power supply for high-frequency low-impedance electrolytic capacitors (LOW ESR) to ensure output ripple and effectively filter out switching power supply faults.

2. MPPT solar maximum power point tracking, automatic intelligent charging management, low power consumption.

3. The maximum conversion efficiency is 93% and the maximum value is 95% depending on the lighting conditions.

4. Automatic intelligent three-stage charging mode. The self-tracking solar charging current is automatically resized.

5. With a no-load current of 3 mA, even a very weak morning sun can be easily and automatically activated without manual switching.

6. With input reverse polarity protection. The ultra-low dropout designed exclusively prevents reverse polarity protection of MOS transistors, and reverse input does not work.

7. With output reflow protection. Effectively prevent the charge meter of the nighttime reverse battery!

MPPT voltage: adjustable, the voltage of different MPPT solar modules is different, even if the MPPT voltage cannot adjust the MPPT solar controller, can it be called MPPT? The MPPT control technology uses a charging efficiency ratio control scheme of the charge meter, which is generally about 30% higher than the DC-DC step-down power supply MCU + PWM. Make full use of solar energy and operate at low power. Reduce power loss! The MPPT function can effectively prevent the charging voltage of the solar panel from being slowly and slowly killed by the battery.

Note: The first charge will pre-adjust the output voltage. Please monitor the battery voltage closely to prevent overcharging! Don't have unprotected lithium batteries!

Debugging method:

Step 1: If the voltage is output in step 2, connect the solar cell and do not charge the bottle. If there is no output, the small output rotates counterclockwise slowly counterclockwise until the output voltage MPPT.

Step 2: Transmitting the small output voltage counterclockwise until the red and blue indicators flash, then adjusting the coarse output voltage to the full cutoff voltage.

Step 3: Repair the depleted battery and monitor the charging current on the output string ammeter. Adjust the potentiometer with MPPT until the charging current is maximum.

Step 4: Fill the battery only. If the blue light rotates clockwise, increase the output voltage until the red light is on. Then slowly shift a small output voltage counterclockwise until only blue is lit, then use a multimeter to make sure the cutoff voltage is correct to avoid overcharging!

Transfer method instead of using solar power:

Step 1: The power supply has adjusted the solar MPPT voltage (e.g. 18V).

Step 2: If the output voltage is adjusted in a clockwise direction until there is no large MPPT voltage output, do not connect the power supply to the input terminal and do not charge the battery. Then slowly rotate counterclockwise until the small MPPT transmission just has the output voltage.

Step 3: Decrease the output voltage counterclockwise until the red and blue indicators flash, then coarsely adjust the output voltage to the full cutoff voltage.

Step 4: Fill the battery only. If the blue light rotates clockwise, increase the output voltage until the red light is on. Then slowly shift a small output voltage counterclockwise until only blue is lit, then use a multimeter to make sure the cutoff voltage is correct to avoid overcharging!
