:wink: excuse me,

is there anyone who know about this digital controller? controller for Solar Panel Battery and Load. I need the concept, schematic and the code :). I just knew about the analog controller.

i need this information, please help me! :( :(

Sorry i just attached my DXP schematic here. :D

thank you very much for the information. nice to know that.

Are you asking about an already existing device that you have in your hand or are you looking for advice on how to build such a device?

If it is an already existing device, please give us the device manufacturer and model number. Without that, we are as clueless as you are.

If you are looking for advice on how to build such a device, we must ask your purpose. If this is a student project, folks around here are reluctant to do your work for you. We may give hints about how to approach such a project and will help out when you run into a specific problem, but no one will give the whole project laid out for you. Before you post your problem be sure to read Help, My "..." Doesn't Work!

If this is a hobby project, posting on the main AVR forum would probably give you better response than on this forum, which is dedicated to the GCC compiler. In this case, you will likely get pointers and ideas, but it is unlikely anyone already has done this project and has the concept, schematics, and code sitting around ready for you.

No matter what, reading Newbie? Start here! will give you some starting points.

So, friend, what's up?

Engineering seems to boil down to: Cheap. Fast. Good. Choose two. Sometimes choose only one.

Newbie? Be sure to read the thread Newbie? Start here!

I'm looking for advice on how to build such a Solar controller.

thank you for the attention and the information. I just wanted to know about this project. I had a project like this in my Polytechnic final task.

I hope there is someone who know a lot about this Project here. amin. :)

Are you looking for a maximum power point controller (mppt) or just a generic charge rate and maximum charge controller?

There have been a number of articles and papers available on the web. Try google for maximum power point.

I'm looking for a maximum charge controller for Solar Panel.

Firstly, I will search an article MPPT in google.

Thank you very much for the information master. :)

The schematic you included has only on-off charge control. For MPPT, you will need far more than that.

for maximum power point tracking, you have to measure voltage and current (for some algorithms only the voltage is enough). Then according to your algorithm, you decide the duty cycle of the power converter. If you want, I can send you my project's summary which is a design of a MPPT for a solar car.

I see :? . I'm a newbie in MPPT, so I need to learn more about it. I need to search more about MPPT. In my head I just thought about how to control the voltage and current on Battery and Load Line, and so the battery and load not overloaded.

I try to measure the voltage and the current with LCD 2x16. So, I can see the current and voltage value of my solar panel controller.

This is my Final Task in Polytechnic master. I hope you want to help me about MPPT concept. Certainly, I'll search about MPPT in my own on Google. :)

Pretty Nice project buddy. It's about solar car. :D

Ok, I accept with pleasure your helpful :). Please go check into your PM. nice to know you buddy.

in this project I make a Solar Display with Dot matriks 64x8.

and I must to design a Controller for my Solar Panel, so if the battery 1 is full, the current from solar panel will charge battery 2. :)

I wanted to say I already have MPPT design that uses an avr for a controller and it works:

There was a good article about MPPT controller using an AVR in Circuit Cellar, maybe 3 years ago. The article has been available on-line.

I made this project: http://merk.wikidot.com/eng-elec.... There is 2W solar panel controller with MPPT. Atmega8 chip. This is for charge cell phones and SLA 6/12V. Open source code is here too. There is other method of find max power point of solar panel. As for me, this is more robust method, then voltage measurement and find solution equation.
