Arduino Solar Panel Charge Controller

If you are planning to install an off grid solar system with a battery bank you ll need a solar charge controller.

Arduino solar panel charge controller.

1 based on mppt algorithm. You must be logged in with your arduino account to post a comment logged in with your arduino account to post a comment. 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. It seems to provide more power than my arduino solenoid valves consume.

There are many charge controllers available but ordinary cheap ones are not efficient enough to use with maximum power from solar panels. Initially i made a lm317 based charge controller and an energy meter for monitoring the system. Led indication for the state of charge. Arduino pv mppt solar charger project tutorial by abhi verma.

I am using a small 20w solar panel but if the reading on the controller is any good my battery is always fully charged i e. Finally i made a pwm charge controller. The battery voltage will increase gradually. 20x4 character lcd display for displaying voltages current power.

Stage 1 bulk charge. The output voltage of the acs712 is 2 5v with no input while the spec sheet specifies 66 to 185 mv a output sensitivity. Arduino pwm solar charge controller v 2 02. Arduino will connect the solar panel to the battery directly 99 duty cycle.

As the input voltage from the solar panel rises the charge controller regulates the charge to the batteries preventing any overcharging and disconnect the load when the battery is discharged. This is a simplified version of my solar panel battery charge controller using arduino one can easily add the ideas from that project to this one. Solar panel battery charge controller using arduino pictures of power box and arduino solar charge regulator. And we have about 300 sunny days per year.

All this is just a refined documentation and a suitable pcb design to perfectly fit arduino pro. Arduino pwm solar charge controller ino version 1 1 code download. It is a device that is placed between the solar panel and the battery bank to control the amount of electric energy produced by sola. One response to a solar charge controller made with arduino sheetansh kaushik says.

Charge regulator with power box connections to regulator inside the box. Schematic and code of this charge controller is by julian ilett he is the mastermind behind this clever thing. May 8th 2014 at 17 10 58. Solar panel battery charge controller switching circuit.
