Conversion efficiency: Max: 93% Peak: 95% Different lighting conditions may vary.

 

 

Charging mode: fully automatic and intelligent three-stage charging mode. Self tracking solar power and automatic adjustment of charging current

 

 

No load current: 3MA can easily start automatically even under weak sunlight in the morning, eliminating the need for manual switching

 

 

Input reverse protection: Yes. Exclusive design of MOS tube ultra-low voltage differential anti reverse connection protection, input reverse connection does not work.

 

 

Output backflow protection: Yes. Effectively prevent electric backflow of the battery at night with the charging board!

 

 

Wiring method: with wiring terminals

 

 

MPPT voltage: can be adjusted arbitrarily, and the MPPT voltage varies for different solar modules. Can an MPPT solar controller that cannot even adjust the MPPT voltage be called an MPPT? The charging efficiency of the charging board using MPPT control technology is improved by about 30% compared to the general DC-DC step-down power supply or MCU+PWM control scheme. Can fully utilize solar energy and achieve low-power operation. Reduce power loss! The MPPT function can effectively prevent the voltage of the solar panel from being dragged by the battery, resulting in slow charging.

 

 

 

Applicable scope:

 

1w-100W 9V-28V suitable for 9V 12V 18V 24V solar panel charging batteries, nickel cadmium, nickel hydrogen, lithium batteries (battery packs), wind turbines, solar street lights, etc

 

 

Both the input and output terminals are equipped with high-end high-frequency low resistance electrolytic capacitors (LOW ESR) specifically designed for switching power supplies to ensure output ripple. It can effectively filter out burrs in switch mode power supplies.

 

 

Notes:

 

Please adjust the output voltage in advance for the first charging and closely monitor the battery voltage to prevent overcharging! Do not charge unprotected lithium batteries!

 

 

 

Debugging method:

 

 

Step 1: Connect the solar cell without connecting the rechargeable battery. If there is voltage output, proceed to step 2. If there is no output, slowly adjust the MPPT counterclockwise until there is output voltage.

 

 

Step 2: Turn down the output voltage counterclockwise until the red and blue lights flash, then roughly adjust the output voltage to fully charge the cutoff voltage

 

 

Step 3: Connect a dead battery and connect an ammeter at the output end to monitor the charging current. Fine tune the MPPT potentiometer until the charging current reaches its maximum.

 

 

Step 4: Connect a fully charged battery, and if the blue light is on, increase the output voltage clockwise until the red light is on. Then slowly decrease the output voltage counterclockwise until the blue light is just on, and use a multimeter to measure and determine if the cutoff voltage is correct to avoid overcharging! If the MPPT voltage value of the solar panel is known, you can directly inquire with the seller who sells the solar panel to you about the MPPT voltage value

 

 

 

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

 

 

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

 

 

Step 2: Connect the stabilized power supply to the input terminal, not to the charging pool. If there is voltage output, adjust the MPPT clockwise until there is no voltage output. Then slowly adjust 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 roughly adjust the output voltage to fully charge the cutoff voltage

 

 

Step 4: Connect a fully charged battery, and if the blue light is on, increase the output voltage clockwise until the red light is on. Then slowly decrease the output voltage counterclockwise until the blue light is just on, and use a multimeter to measure and determine if the cutoff voltage is correct to avoid overcharging!
