"5A MPPT Solar Charge Controller with 95% Efficiency - Smart 3-Stage Charging, Reverse Polarity Protection for Lithium/Lead Acid Batteries"

<ul><li>Ultra-low no-load current of 3 mA enables activation with minimal sunlight</li><li>High-frequency low-impedance electrolytic capacitors ensure minimal output ripple and effective fault filtering</li><li>Automatic three-stage charging mode adjusts solar charging current dynamically</li><li>Achieves up to 95% conversion efficiency, adapting to varying lighting conditions</li><li>MPPT technology maximizes solar energy utilization with intelligent charging management</li></ul>

Model

Feature:
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!

Specification:
Item Type:Solar Panel Regulator
Input Voltage: DC 8-28V input DC voltage. (No AC input)
Output Voltage: DC 5-26V continuously variable transmission
6V battery can charge 12 or 8.4V, 12.6V, 16.8V lithium battery
7.2V, 10.8V, 14.4V lithium iron phosphate battery
2-4 series lithium battery, lithium iron phosphate charging management board
Output Current: 5A Maximum 
Charging Indicator: Yes. The fast red and blue lights of the fast red light flash alternately. Automatically stopped.
MPPT Function: MPPT maximum power point automatic tracking, maximizing the use of solar charging
Low Voltage: 1V (the same is true for buck regulators, the input voltage is at least higher than the output 1V)
Low Power Consumption: Yes. Ultra-low voltage design for low power consumption and high efficiency, professionally adapted to solar panels
Operating Temperature: Industrial Grade (-40℃ to + 85℃)
Load Adjustment Rate: ±1%
Voltage Regulation Rate: ±0.5%
Connection: With Terminal
MPPT voltage: adjustable, the voltage of different MPPT solar modules is different, even if the mppt voltage can not 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 (eg 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
