Solar Panel Charge Controller Using Arduino

The output voltage of the acs712 is 2 5v with no input while the spec sheet specifies 66 to 185 mv a output sensitivity.

Solar panel charge controller using arduino.

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. 8 charge your cellphone tablets any gadgets through usb port. Microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display.

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 panel battery charge controller switching circuit. Use an arduino two small. 5 power of solar panel 50 watts.

Project tutorial by abhi verma. Specification of version 2 charge controller. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. We will also touch on power management and charge controllers.

Arduino pv mppt solar charger. 1 based on mppt algorithm. 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. 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. 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. 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. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt.

This is a simplified version of my solar panel battery charge controller using arduino. Solar power can often be a useful solution for powering such devices. I combine both the energy meter and charge controller in this design. Above is a generic arduino nano but the code will work on any arduino style microcontroller.

Resistors 3 x 200r 3 x330r 1 x 1k 2 x 10k 2 x 20k 2x 100k 1x 470k. Charge regulator with power box connections to regulator inside the box. This is an updated version of solar panel charge controller using arduino. One can easily add the ideas from that project to this one.

Led indication for the state of charge. But ordinary cheap ones are not efficient enough to use with maximum power from solar panels. 20x4 character lcd display for displaying voltages current power. 1 charge controller as well as energy meter 2.

3 load current support up to 10a. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. 2 maximum input current 5a. You can also use other arduino board like pro mini micro and uno.
