Mppt voltage: Any adjustable, different solar modules MPPT voltage is different, even mppt voltage can not be adjusted mppt solar controller, can be called mppt? Low power design. Reduce power loss! The MPPT function can effectively prevent the solar panel voltage from being dragged by the battery and charging slowly.
Note: Please adjust the output voltage in advance for the first charge and monitor the battery voltage to prevent overcharge! Do not charge unprotected lithium batteries!
Debugging method:
Step 1: Connect the solar cell, do not connect to the charged bottle, if the output has voltage, step 2. If there is no output, slowly turn the MPPT down counterclockwise until there is an output voltage.
Step 2: Turn the output voltage counterclockwise until the red and blue lights flash, then coarsely adjust the output voltage to the full cutoff voltage.

Step 3: Connect the unpowered battery and monitor the charging current at the output string ammeter to fine tune the MPPT potentiometer until the charging current is maximum.

Step 4: Connect the battery that is just full. If the blue light is turned, turn the output voltage clockwise until the red light is on. Then slowly turn down the output voltage counterclockwise until the blue light is on, then use a multimeter to determine if the cutoff voltage is correct to avoid overcharging! If the MPPT voltage value of the solar panel is known, (MPPT voltage value can directly ask the seller who sells the solar panel.)

The method of replacing the solar energy with a regulated power supply:

Step 1: Adjust the regulated power supply to the solar MPPT voltage (eg 18V)

Step 2: Connect the regulated power supply to the input terminal without charging the battery. If the output voltage is available, increase the MPPT clockwise until there is no voltage output. Then slowly turn the MPPT down counterclockwise until it has just the output voltage.

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

Step 4: Connect the battery that is just full. If the blue light is on, turn the output voltage clockwise until the red light is on. Then slowly turn down the output voltage counterclockwise until the blue light is on, then use a multimeter to determine if the cutoff voltage is correct to avoid overcharging!

Solar cell maximum power point tracking (MPPT)
Solar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell assembly always outputs maximum power when the sun's light intensity changes, in order to achieve full and efficient use of solar energy. Under normal circumstances, the output charging current is automatically adjusted according to the solar lighting conditions, so that the solar panel output power can always be maintained at the maximum power point, and the product of the output voltage and the charging current (output power) is maximized.
