Packaging & Delivery

1 Cell LiPo Lithium Battery Charging Module CN3791 MPPT Solar Charge Controller Board 12V 2-Pin JST Connectors

Description:

- It is a 12V charging board module. - This is a solar charger used for single-cell lithium battery maximum power point tracking (MPPT). - It is to ensure that the light intensity changes and the photovoltaic cells output maximum power to make full use of solar energy. - Usually,a switch-mode DC-DC converter is needed to realize the MPPT function,keeping the product of output voltage and charging current maximized (output).

Features:

1>.Complete charge management for single-cell lithium batteries. 2>.Trickle-charge the deeply discharged battery. 3>.Support automatic recharge function. 4>.There are charging status and charging end status indication. 5>.Support soft start function. 6>.Support battery over-voltage protection.

Parameters:

1>.Product Name:12V Charging Board Module 2>.Input Voltage:12V 3>.Output Voltage:DC 3.7V~4.2V 4>.Interface:2pin PH2.0/JST 5>.Charging Current:2A 6>.Constant Voltage Charging Voltage:4.1V~4.3V 7>.PWM Switching Frequency:300KHz 6>.Work Temperature:-40℃~85℃ 7>.Work Humidity:5%~95%RH 8>.Size:45*20*10mm

Working Principle:

1>.This MPPT solar charger enables you to get as much power as possible from solar panels or other photovoltaic devices and pack it into a rechargeable lithium battery. 2>.It is very easy to use,just insert the solar panel into one side of the solar charger,and then insert the battery into the other side,you can start charging. 3>.When the current output capacity of the input power supply is reduced,the internal circuit of CN3791 can automatically track the maximum power point of the solar panel.The user does not need to consider the worst case,and can maximize the output power of the solar panel,which is very suitable for applications using solar panel power supply .
