It can be nice measure curent from battery to load. I understand that this feature is not required for Mppt. Just for loging, battry life, etc

It would be nice if you could point me to the right direction to enhance the design for connecting multiple solar panels or if you could modularize the system to be able to add multiple panels.

In the existing code, first I connect the ESP8266 module to my router by entering the ssid and password,then upload the code to arduino.I need the code should option for entering SSID and Passwoed,so that when user upload the code to arduino,the ESP8266 module connect to the router automatically.

What about the wind turbin with mppt?

This happens first due to the high impedance of the data lines during startup, but the code should turn the mosfet's off as soon as possible.

The snubber used is a RC (R6 200ohm and C8 0.1uF) across the inductor. I am wondering if it's more efficient and less noisy to use a RC + C snubber. My solar controller will be near some radio equipment and I'd like to eliminate any ringing from the inductor.

There's a good article about this here: http://www.hagtech.com/pdf/snubber.pdf and I plan on doing some testing to make a better snubber.

The battery icon always shows about half full. Change the code to show the state of charge.

Hello,

I have a 300W Solar Cell laying around and I want to use it wit yout MPPT-Design.
The problem: it has about 40V maximum.
Where is the 25V limit, I mean the mosfets can handle 55V...

Is the Problem D2 ( the MOSFET-Diver ), because it is directly conneted to the solarcell Voltage?
A Solve would be to just use a LM2596 Buck converter and drive D2 with that voltage..

Or is it somewhere else?

Sorry for my (hopefully not so) bad English.

Gerne auch in Deutsch ;-)
