Air load current: 3mA can be easily started automatically even in the morning weak sunlight to avoid manual switch.

Enter anti -connection protection: Yes.Exclusive design of MOS tube ultra -low voltage deviation anti -anti -anti -counterpart protection, input anti -connection does not work.

Output reflux protection: Yes.Effectively prevent the electric back charging board of the night battery!

Wiring method: there are wiring terminals

MPPT voltage: arbitrarily adjustable, different solar components MPPT voltage is different. Can the MPPT solar controller that cannot even adjust the MPPT voltage can be called MPPT?The charging board using MPPT control technology is compared with the general DC-DC antihypertensive power supply or MCU+PWM control solution. The charging efficiency is increased by about 30%.Can make full use of solar energy and achieve low power consumption.Reduce electricity loss!The MPPT function can effectively prevent solar cell board voltage from being dragged to death by the battery and charging slowly.

Scope of application:

1W-100W 9V-28V is suitable for 9V 12V 18V 24V solar cell board to battery, nickel-cadmium, nickel-metal hydride, lithium battery (battery pack) charging, wind power generator. Solar street lights, etc.

The input and output terminals use high -end switching power supply -specific high -frequency low -resistance electrolytic capacitors (LOW ESR) to ensure the output ripples.It can effectively filter the burrs in the switching power supply.

Note:

Please adjust the output voltage in advance for the first charging and closely monitor the battery voltage to prevent overload!Do not charge the lithium battery that is not protected!

Debug method:

Step 1: Connect the solar cell and not connect to the charging bottle.If there is no output, slowly adjust the MPPT until there is output voltage.

Step 2: The small output voltage is adjusted counterclockwise until the red and blue lights flashed, and then the thick -tone output voltage to the full -off voltage

Step 3: Enter the battery with no power, and monitor the charging current at the output string current meter, and fine -tune the MPPT potentiometer until the charging current is the largest.

Step 4: Enter the battery that is just full, if the blue light is clockwise, the large output voltage is turned on until the red light is on.Then slowly adjust the output voltage instead until the blue light is on, and then use a universal meter to determine whether the deadline voltage is correct to avoid overload!If the MPPT voltage value of the solar panel is known, (MPPT voltage value can directly ask the solar panel to your seller.)

Method of the adjustment of solar energy with a voltage voltage power:

Step 1: Rather the voltage voltage power to the solar energy MPPT voltage (such as 18V)

Step 2: The voltage voltage power supply is connected to the input terminal, and the battery is not connected.Then slowly adjust the MPPT until there is exactly output voltage.

Step 3: Inclocking the small output voltage against the clockwise until the red and blue light flashes, and then the thick output voltage to the full -off voltage

Step 4: Enter the battery that is just full, if the blue light is clockwise, the large output voltage is turned on until the red light is on.Then slowly adjust the output voltage instead until the blue light is on, and then use a universal meter to determine whether the deadline voltage is correct to avoid overload!
