5A MPPT Solar Controller

Scope of application: 1w-100W 9V-28V Suitable for 9V 12V 18V 24V solar panels to charge batteries, nickel-cadmium, nickel-hydrogen, lithium batteries (battery packs), wind turbines, solar street lights, etc.

Both the input and output terminals use high-frequency low-resistance electrolytic capacitors (LOW ESR) dedicated to high-grade switching power supplies to ensure the output ripple. It can effectively filter out the glitch in the switching power supply.

Module parametersModule nature: with real MPPT solar maximum power point tracking function, automatic and intelligent charging management, low power consumptionInput voltage: DC 8-28V input DC voltage. (It is forbidden to input AC power)Output voltage: DC 5-26V stepless adjustable output,Can charge 6V or 12 batteries or 8.4V, 12.6V, 16.8V lithium batteries7.2V, 10.8V, 14.4V LiFePO4 battery2-4 strings of lithium batteries, lithium iron phosphate charging management board Output

current: 2A/5A There are two types of maximum charging current: A version 5A B version 2A The default delivery of 5A version ACharging indicator: Yes. The red light is always on for fast charging, and the red and blue light alternately flashes when fully charged. Automatically stops when full.MPPT function: Yes. MPPT maximum power point automatic tracking function, can make full use of solar energy chargingMinimum voltage difference: 1V (because it is a step-down voltage regulator module, the input voltage is at least 1V higher than the output)Ultra-low power consumption: yes! Adopt ultra-low dropout design to achieve low power consumption and higher conversion efficiency, professionally adapted to solar panelsOperating temperature: Industrial grade (-40°C to +85°C)Load Regulation: ±1%Voltage regulation rate: ±0.5%Conversion efficiency: Max: 93% Peak: 95% Different lighting conditions vary.Charging method: fully automatic and intelligent three-stage charging mode. Self-tracking solar power automatically adjusts the charging currentNo-load current: 3MA can easily start automatically even in weak sunlight in the morning, eliminating the need for manual switches.Input reverse polarity protection: Yes. MOS tube ultra-low dropout anti-reverse connection protection, input reverse connection does not work.Output backflow protection: Yes. Effectively prevent the battery's electricity from flowing back to the charging board at night!Wiring method: with terminalsmppt voltage: It can be adjusted arbitrarily. Different solar modules have different MPPT voltages. Can an mppt solar controller that cannot even adjust the mppt voltage be called mppt? low power design. Reduce power loss! The MPPT function can effectively prevent the solar panel voltage from being dragged to death by the battery and thus charging slowly.

The method of replacing solar energy with regulated power supply:

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

Step 2: The regulated power supply is connected to the input terminal, not the rechargeable battery. If the output has voltage, turn up the MPPT clockwise until there is no voltage output. Then slowly turn down the MPPT counterclockwise until there is just an output voltage.

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

Step 4: Connect the battery that is just full, if the light is blue, turn up the output voltage clockwise until the red light is on. Then slowly adjust the output voltage counterclockwise until the blue light is just on, and then measure with a multimeter to determine whether the cut-off voltage is correct to avoid overcharging!

2A/5A high-current intelligent trickle, constant current, and constant voltage charging management board, automatically stop when full, sleep at night, start autonomously during the day, and realize unattended and fully intelligent management.

Solar Cell Maximum Power Point Tracking (MPPT)

Solar Cell Maximum Power Point Tracking (MPPT) is to ensure that when the solar light intensity changes, the photovoltaic cell module has always output the maximum power 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 as to ensure that the output power of the solar panel can always be maintained at the maximum power point, and the product of the output voltage and the charging current (output power) is maximized.

Features of charging management board:

1. The maximum power point tracking of the solar cell, the output current is greater than the current of the solar panel, the real ultra-high-efficiency MPPT, supports 8-28V, solar high current charging within 100W, it is recommended that each solar panel is equipped with this module) Multiple modules can be connected in parallel to expand the charging current

2. The output voltage can be adjusted arbitrarily, CC-CW automatic control (can support single or multi-cell lithium battery or lithium iron phosphate or lead-acid battery, high-power LED, etc.)

3. Battery for complete charge management

4. PWM switching frequency: 300KHz

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

6. Trickle charging of deeply discharged batteries

7. Dual indication of charging status and charging end status (red light is on when charging / blue light is on when fully charged / red light is flashing and blue light is always on, indicating that the battery is not connected)

8. Low-power soft-start function
