mppt voltage: any adjustable, different solar modules MPPT voltage is different, even mppt voltage can not be adjusted mppt solar controller, can it be called mppt? Low power design. Reduce power loss! The MPPT function can effectively prevent the solar panel voltage from being dragged dead by the battery and thus charging slowly.

Note: Please adjust the output voltage before charging and closely monitor the battery voltage to prevent overcharging! Do not charge unprotected lithium batteries!

Debugging method:

Step 1: Connect the solar cell, not the charged bottle, if the output voltage step 2. If there is no output, slowly turn down MPPT counterclockwise until there is output voltage.

Step 2: Turn down the output voltage counterclockwise until the red and blue lights flash, then turn down the output voltage coarse to full cut-off voltage

Step 3: Plug in the battery with no power, and monitor the charging current with a series ammeter at the output end, and fine-tune the MPPT potentiometer until the charging current.

Step 4: Plug in the battery that is just full. If the blue light is on, increase the output voltage clockwise until the red light is on. Then slowly reduce the output voltage counterclockwise until the blue light is on, and then measure with a multimeter to determine whether the cut-off voltage is correct to avoid overcharging! If the MPPT voltage value of solar panels is known, (MPPT voltage value can be directly asked to sell solar panels to your seller.)

The method of replacing solar energy with regulated power supply:

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

Step 2: The voltage regulator power supply is connected to the input end, not to the charged battery. If the output voltage is present, increase the MPPT clockwise until there is no voltage output. Then slowly turn down the MPPT counterclockwise until the output voltage is just right.

Step 3: Turn down the output voltage counterclockwise until the red and blue lights flash, then turn down the output voltage coarse to full cut-off voltage

Step 4: Plug in the battery that is just fully charged. If the blue light is on, increase the output voltage clockwise until the red light is on. Then slowly reduce the output voltage counterclockwise until the blue light is on, and then measure with a multimeter to determine whether the cut-off voltage is correct to avoid overcharging!

Solar Cell Power Point Tracking (MPPT)

Solar cell power point tracking (MPPT) is to ensure that when the solar light intensity changes, the photovoltaic cell module has been output power to achieve the full use of solar energy. Under normal circumstances, the output charging current is automatically adjusted according to the solar lighting conditions at all times, so as to ensure that the output power of the solar panel can always be maintained at the power point, and the output voltage and charging current product (output power) is maintained.

Charging management board Features:

one. Solar cell power point tracking, the output current is greater than the solar panel current, the real excess MPPT, support 8-28V, 100W solar current charging, it is recommended that each solar panel with a module) can be multiple modules in parallel to expand the charging current

2. Adjustable output voltage, CC-CW automatic control (can support single or multiple lithium batteries or lithium iron phosphate or lead-acid batteries, high-power LED, etc.)

3. Complete battery charge management

4. PWM switching frequency: 300KHz

5. Constant charge current set by external resistor (preset 5000mA/2000MA)

6. Trickle charge a deeply discharged battery

Seven. Dual indicator of charging status and charging end status (red light on when charging/blue light on when charging/blue light on red light flashing blue light indicates that no battery is connected)

8. Low power soft boot function
