+# MPPT_Master
+ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0)
+
+
+
+This is a project build for a Arduino based Solar MPPT charge controller.It has features like: LCD display,Led Indication,
+Wi Fi data logging and provision for charging different USB devices.It is equipped with various protections to protect the 
+circuitry from abnormal condition.
+
+The microcontroller used is in this controller is Arduino Nano. This design is suitable for a 50W solar panel to charge 
+a commonly used 12V lead acid battery. You can also use other Arduino board like Pro Mini,Micro and UNO.
+
+Now a days the most advance solar charge controller available in the market is Maximum Power Point Tracking (MPPT).
+The MPPT controller is more sophisticated and more expensive.It has several advantages over the earlier charge controller.
+It is 30 to 40 % more efficient at low temperature.But making a MPPT charge controller is little bit complex in compare to 
+PWM charge controller.It require some basic knowledge of power electronics.
+
+I put a lot of effort to make it simple, so that any one can understand it easily.If you are aware about the basics of MPPT 
+charge controller then skip the first few steps.
+
+The Maximum Power Point Tracker (MPPT) circuit is based around a synchronous buck converter circuit..It steps the higher solar
+panel voltage down to the charging voltage of the 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.
+
+
+Specification of version-3 charge controller :
+
+1.Based on MPPT algorithm
+
+2. LED indication for the state of charge
+
+3. 20x4 character LCD display for displaying voltages,current,power etc
+
+4. Overvoltage / Lightning protection
+
+5. Reverse power flow protection
+
+6. Short Circuit and Over load protection
+
+7. Wi Fi data logging
+
+8.USB port for Charging Smart Phone /Gadgets
+
+Electrical specifications :
+
+1.Rated Voltage= 12V
+
+2.Maximum current = 5A
+
+3.Maximum load current =10A
+
+4. In put Voltage = Solar panel with Open circuit voltage from 12 to 25V
+
+5.Solar panel power = 50W
