Make MPPT solar controller with LCD Arduino 12V 24V

I previously built an MPPT charger ( • Video ). It is very strong and durable, but it always works silently. I can not know what mode it is working in ?. Battery voltage, Current. So today I'm going to build a 10A solar battery charger (10A is enough for me, because my PV only has 100W). The prototype of the project is from Tim Nolan. Because this is an open source project, so I used the arduino code on www.instructables.com/id/ARDU... and microcontrolere.wordpress.com.... I have modified the code and hardware to suit me. I thanks to all of them for sharing their knowledge. After construction, it works very well, always 90% efficiency. Mosfet is very cool. In the next version, I will build a charger with greater current and voltage. Wait for me.

[@adewaledipo]

Thanks for your wealth of knowledge. You are doing a great job. How can we modify it to allow more current? I guess the use of acs758, more MOSFETs and a bigger coil

[@adewaledipo]

How do I change it to charge 24v battery

[@PhdHung]

@@adewaledipo Change values in ino files. You will easily see the value of min and max.

[@pinklemon10]

Very nice project! And love watching your skillset at work. A nice collection of open source MPPT and PWM diy solar, wind and hydro charge controllers would be of great value to humanity. Especially if designed to be easily self-maintained and not throwaway like commercial systems. Watching your work with great interest...

Yes, thank you very much, I'm glad to hear that.

hello i was interested in your project however i would have a few questions 1. what function does the yellow wire which leads from UCC 712, 2. what function is performed by the diode which is added on the bottom, both are missing in the diagram, thank you for the answer

Hi. If i need only 1A for charging my 90a battery (because i dont want it to boil because of overcharging) can i change settings?

[@batchit]

Hi, Thank you for your work on this project I have just started on building it. I noticed your Inductance Meter, do you have any plans for it as I would be interested in building it too? Once again thank you and keep up the good work.

[@DanielStingBR]

why it keep showing current when the solar panel is disconected? when it shows that the charge is at 100%, it would stop the chargem isn't it?

[@ed-jf3xh]

Shouldn't the display show a drain on the battery when PV not connected? How do you stop your charger from draining the battery during the night?

[@calebemeritus3725]

the design is pretty much ok i even added some code to it to make it more intelligent like keypad to select from 12v to 48v panel.also with the keypad you can set the float voltage and bulk voltage to suit your taste.i switched the code back to work for 16x2 lcd.now the design is very compact and advance it may seem a little bit complex to others but now it more intelligent thanks.God bless you
