Solar Panel Regulator 5A Solar Battery Charge Controller

1. The input and output terminals consist of a high-side switching power supply with low-impedance, high-frequency (LOW ESR) electrolytic capacitors to ensure output ripple and effectively filter out switching power supply faults.
2. MPPT solar maximum power point tracking, automatic intelligent charge management, low power consumption.
3. Maximum conversion efficiency is 93%, and the maximum value is 95% depending on lighting conditions.
4. Intelligent three-stage automatic charging mode. The self-tracking solar charging current is automatically resized.
5. With a no-load current of 3 mA, even very weak morning sunlight can activate easily and automatically without manual switching.
6. With input reverse polarity protection. The ultra-low voltage drop design exclusively prevents reverse polarity protection for MOS transistors, and the reverse input does not function.
7. With output reflow protection. Effectively prevents nighttime battery charge meter reverse polarity!

Output Current: 5A maximum
Charging Indicator: Yes. The red and blue LEDs flash alternately. Automatically shuts off.
Function: Automatic maximum power point tracking (MPPT), maximizing solar charging utilization.
Low Voltage: 1V (This also applies to step-down regulators; the input voltage must be at least 1V higher than the output voltage.)
Low Power Consumption: Yes. Ultra-low voltage design for low power consumption and high efficiency, professionally suited for solar panels.
Operating Temperature: Industrial grade (-40°C to +85°C)
Charge Adjustment Rate: ±1%
Voltage Regulation Rate: ±0.5%
Connection: With Terminal
Voltage: Adjustable. The voltage of different solar modules varies. Even if the voltage cannot be adjusted by the MPPT solar controller, can it still be used? The control technology uses a charge efficiency ratio control scheme of the charge meter, which is generally about 30% higher than a DC-DC MCU + PWM step-down power supply. Fully utilize solar energy and operate at low power. Reduce power losses! This function can effectively prevent the solar panel's charging voltage from being slowly and gradually depleted by the battery.
Note: The first load will pre-adjust the output voltage. Please closely monitor the battery voltage to avoid overcharging! Do not use unprotected lithium batteries!
Debugging Method:
Step 1: If voltage is output in Step 2, connect the solar cell and do not charge the bottle. If there is no output, slowly rotate the small output counterclockwise until the MPPT output voltage is reached.
Step 2: Rotate the small output voltage counterclockwise until the red and blue LEDs flash, then adjust the output voltage to the full cutoff voltage.
Step 3: Repair the discharged battery and monitor the charging current on the output channel ammeter. Adjust the potentiometer until the charging current is at its maximum.
Step 4: Only fill the battery. If the blue indicator light rotates clockwise, increase the output voltage until the red indicator light illuminates. Then, slowly increase the output voltage counterclockwise until only the blue light is illuminated. Use a multimeter to ensure the cutoff voltage is correct to prevent overloading!
Transfer method instead of using solar power:
Step 1: The power supply has adjusted the solar voltage (e.g., 18V).
Step 2: If the output voltage is adjusted clockwise until there is no longer a significant output voltage, do not connect the power supply to the input terminal and do not charge the battery. Next, slowly turn counterclockwise until the small transmission has just the correct output voltage.
Step 3: Decrease the output voltage counterclockwise until the red and blue lights flash, then roughly adjust the output voltage to the full cutoff voltage.
Step 4: Charge only the battery. If the blue light is rotating clockwise, increase the output voltage until the red light illuminates. Then, slowly turn the output voltage counterclockwise until only the blue light is illuminated, and then use a multimeter to ensure the cutoff voltage is correct to avoid overcharging!
Charge Management Board Function:
1. Monitoring the maximum power point of the solar cell, the output current is higher than the solar panel current, truly ultra-efficient, supports 8-28V, 100W high-current solar charging. It is recommended that each solar panel module be connected in parallel to increase the charging current.
2. Adjustable output voltage, automatic CC-CW control (can support a single or multi-cell lithium battery, lithium iron phosphate battery, or lead-acid battery, high-power LED).
