Solar Panel Charge Controller Using Arduino

Charge regulator with power box connections to regulator inside the box.

Solar panel charge controller using arduino.

This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery. Arduino pwm solar charge controller v 2 02 to solve this problem i made this new version charge controller so that anyone can use it without changing the hardware and software. Solar power can often be a useful solution for powering such devices. Input voltage solar panel 12 to 24v.

Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt. 3 load current support up to 10a. But ordinary cheap ones are not efficient enough to use with maximum power from solar panels. 5 power of solar panel 50 watts.

Led indication for the state of charge. Specification of version 3 charge controller. Ground of solar panel and battery is joined together. 8 charge your cellphone tablets any gadgets through usb port.

Project tutorial by abhi verma. I combine both the energy meter and charge controller in this design. Connection and usage of this arduino solar charge controller is very simple there are 2 input leads from solar panel and and 2 output leads going to the lead acid battery. Solar panel battery charge controller switching circuit.

The output voltage of the acs712 is 2 5v with no input while the spec sheet specifies 66 to 185 mv a output sensitivity. Any load should be connected directly on battery terminals and charge controller will automatically handle the. 1 based on mppt algorithm. Arduino pv mppt solar charger.

Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. This is a simplified version of my solar panel battery charge controller using arduino. The microcontroller used is in this controller is arduino nano. Charge regulator with power box connections to regulator inside the box the output voltage of the acs712 is 2 5v with no input while the spec sheet specifies.

We will also touch on power management and charge controllers. In this tutorial we will discuss how to select the proper solar panel based on your power requirements particularly for projects using arduino. 20x4 character lcd display for displaying voltages current power. Use an arduino two small.

Microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. Specification of version 2 charge controller. Above is a generic arduino nano but the code will work on any arduino style microcontroller.

You can also use other arduino board like pro mini micro and uno. 2 maximum input current 5a. Resistors 3 x 200r 3 x330r 1 x 1k 2 x 10k 2 x 20k 2x 100k 1x 470k. One can easily add the ideas from that project to this one.
