Solar charger Li-ION battery MPPT CN3791 1S, 6V panel

Product detailed description

This model is designed for charging lithium batteries using constant current/constant voltage (CC/CV). It does not have overcurrent and short circuit protection, not recommended for use with a battery that does not have integrated protection. The module is equipped with connectors for solar panel, battery and output connectors JST-PH-2P 2,0mm.

Function:

This module uses the CN3791 charge controller

• Constant current and constant voltage control for charging the connected lithium battery,
• Solar Maximum Power Point Tracking (MPPT)
• Surge protection - the module will safely charge the battery

The module includes two LEDs. LED marked CH indicates charging. LED marked OK indicates complete charge.

Maximum Power Point Tracking (MPPT) of the solar cell ensures that the PV cell always puts out maximum power to fully utilize the sun's energy when the light intensity changes. In general, the MPPT function must be implemented with the switch mode of the DC-DC converter to maximize the output power of the output voltage and charging current.

Specifications:

Delivery components:

• 1pc Solar charger Li-ION battery MPPT CN3791 1S, 6V panel
• 2pcs connection cable with connectors JST-PH-2P

Notes:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• Due to the nature and characteristics of batteries, Laskarduino is not responsible or liable for any damage, defects, injury, fire, skin burns or any other consequences that may occur from the improper or incorrect use of this module or any battery, device or item. By purchasing this product you accept the previous.
• You must be careful when connecting two cells in parallel. Both cells must have the same voltage. If one cell has a lower voltage, it would discharge to the lowest possible discharge limit. If possible, both cells should have the same voltage. In this case, the tension will be balanced. If the voltage of the two cells is very different, the cell may overheat or worse. When charging two cells in parallel to this module, the charging current of each cell is half of the total charging current of the module, i.e. each cell has the same voltage level.
