Solar Panel Batter Charing Circuit Arduino

The following design is for a solar battery charger ran by an arduino nano.

Solar panel batter charing circuit arduino.

A simple 400 watt inverter circuit with charger that can be very easily built and optimized has been provided electrical projects electrical engineering electronics gadgets electronics projects electronic circuit design arduino circuit board design simple circuit electronic schematics. It can handle a standard lead acid 12v battery like for a scooter or a car. Battery capacity is 1300mah c 10 130mah the solar panel has to provide current 100mah for arduino along with a current not more than 130mah. It can take up to 20v on the input site of the charger.

The microcontroller used is in this controller is arduino nano. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf. Charging voltage is typically around 4 2v.

This uses the energy from some solar cells to charge the batteries and boosts the voltage from it to the 5v used by the arduino uno. This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station. 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 arduino mcu senses the solar panel and battery voltages.

The controller uses two stages charging algorithm. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station.

According to these voltages it decides how to charge the battery and control the load. Aug 30 2015 solar powered led light circuit diagram and schematic design. This uses the energy from some solar cells to charge the batteries and boosts the voltage from it to the 5v used by the arduino uno. The amount of charging current is determined by the difference between battery voltage and charge setpoint voltages.

You can also use other arduino board like pro mini micro and uno. Lets take 100 mah for charging the battery total current required 100 100 200mah from the above calculation it is clear that we need a solar panel of 4v and 200mah. First you ll have to assemble the solar powered battery charger circuit. Emergency household lighting using power leds powered by the solar panel and lead acid battery.
