Solar Panel Charge Controller Using Arduino

This is a simplified version of my solar panel battery charge controller using arduino.

Solar panel charge controller using arduino.

Charge regulator with power box connections to regulator inside the box. Any load should be connected directly on battery terminals and charge controller will automatically handle the. 5 power of solar panel 50 watts. Led indication for the state of charge.

Resistors 3 x 200r 3 x330r 1 x 1k 2 x 10k 2 x 20k 2x 100k 1x 470k. 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. 3 load current support up to 10a. Microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display.

But ordinary cheap ones are not efficient enough to use with maximum power from solar panels. Project tutorial by abhi verma. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. 8 charge your cellphone tablets any gadgets through usb port.

Solar panel battery charge controller switching circuit. Ground of solar panel and battery is joined together. Use an arduino two small. The output voltage of the acs712 is 2 5v with no input while the spec sheet specifies 66 to 185 mv a output sensitivity.

The microcontroller used is in this controller is arduino nano. 1 charge controller as well as energy meter 2. Specification of version 3 charge controller. 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. Specification of version 2 charge controller. 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. Solar power can often be a useful solution for powering such devices.

The arduino tries to maximize the watts input from the solar panel by controlling the duty cycle to keep the solar panel operating at its maximum power point. One can easily add the ideas from that project to this one. You can also use other arduino board like pro mini micro and uno. 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.

I combine both the energy meter and charge controller in this design. We will also touch on power management and charge controllers. 2 maximum input current 5a. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator.

This is an updated version of solar panel charge controller using arduino. Above is a generic arduino nano but the code will work on any arduino style microcontroller. Input voltage solar panel 12 to 24v. This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery.
