+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.
