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.

Led indication for the state of charge. Specification of version 3 charge controller. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. 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.

3 load current support up to 10a. 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. Microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display.

8 charge your cellphone tablets any gadgets through usb port. Project tutorial by abhi verma. 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 power can often be a useful solution for powering such devices.

20x4 character lcd display for displaying voltages current power. Charge regulator with power box connections to regulator inside the box. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. 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.

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. This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery. Ground of solar panel and battery is joined together. 1 based on mppt algorithm.

Arduino pv mppt solar charger. Specification of version 2 charge controller. 5 power of solar panel 50 watts. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt.

Above is a generic arduino nano but the code will work on any arduino style microcontroller. 2 maximum input current 5a. In this tutorial we will discuss how to select the proper solar panel based on your power requirements particularly for projects using arduino. One can easily add the ideas from that project to this one.

Use an arduino two small. We will also touch on power management and charge controllers. You can also use other arduino board like pro mini micro and uno. This is an updated version of solar panel charge controller using arduino.

Input voltage solar panel 12 to 24v. Any load should be connected directly on battery terminals and charge controller will automatically handle the. Resistors 3 x 200r 3 x330r 1 x 1k 2 x 10k 2 x 20k 2x 100k 1x 470k. I combine both the energy meter and charge controller in this design.
