Arduino Solar Panel Battery Charger

Arduino powered solar battery charger.

Arduino solar panel battery charger.

A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. The following design is for a solar battery charger ran by an arduino nano. Or by connecting the li ion battery to the solar module then the solar module to your arduino board via a pair of 5 v wires. This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station.

This arduino board module equipped with a solar panel and a li ion battery can power your arduino project in two ways. The controller uses two stages charging algorithm. The arduino mcu senses the solar panel and battery voltages. Solar panel charges battery battery stores and supplies power runs arduino we like our small solar charger kits for these applications.

It can take up to 20v on the input site of the charger. Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf. This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. Instapark incc1205 12v 5a waterproof pwm solar charge controller.

Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. Charging voltage is typically around 4 2v. The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable.

According to these voltages it decides how to charge the battery and control the load. The v15 v50 v75 and v88 batteries charge efficiently from solar and have an always on mode which keeps them on whether or not a device is drawing any power. Voltage booster s input ranges from 0 9 to 5 0v. Either by connecting your arduino board to the module and the module to its solar panel.

Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. At night the charge circuit disconnects and the battery is used as the power source for the circuit.
