mppt voltage: adjustable, MPPT solar modules in different voltage is different, even mppt voltage can not tune mppt solar controller, can be called mppt it? MPPT control technology using charge sheet charging efficiency ratio control scheme in general or a DC-DC step-down power MCU + PWM lift about 30%. Make full use of solar energy, and low-power operation. Reduce power loss! MPPT function can effectively prevent the solar panels so that the charging voltage is the battery slow slow death.

Note: The first charge in advance regulate the output voltage and please closely monitor the battery voltage to prevent overcharging! Do not unprotected lithium batteries!

Debugging method:

Step 1: Connect the solar cell, do not take the bottle to be charged, if the output voltage in step 2. If there is no transfer of small output counterclockwise slowly until the output voltage MPPT.

Step 2: counterclockwise transfer of small output voltage until the red and blue lights flashing, then coarse output voltage to a full cut-off voltage

Step 3: Access dead battery, and at the output string ammeter to monitor the charging current, MPPT trimming potentiometer until the charging current maximum.

Step 4: Access is just full of batteries, if the blue light is clockwise turn up the output voltage until the red light. Then transfer a small output voltage slowly counterclockwise until just blue lights, and then use a multimeter to measure to determine the cut-off voltage is correct to avoid overcharge!

ransfer methods instead of using the power supply of solar energy:

Step 1: The power supply was adjusted Solar MPPT voltage (such as 18V)

Step 2: The power supply connected to the input terminal, do not take the battery to be charged, if the output voltage is adjusted clockwise until no large MPPT voltage output. Then slowly counterclockwise until the transfer of small MPPT just have the output voltage.

Step 3: anti-clockwise turn down the output voltage until the red and blue lights flashing, then coarse output voltage to a full cut-off voltage

Step 4: Access is just full of batteries, if the blue light is clockwise turn up the output voltage until the red light. Then transfer a small output voltage slowly counterclockwise until just blue lights, and then use a multimeter to measure to determine the cut-off voltage is correct to avoid overcharge!

Charge Management board features:
