Charge controller circuit pdf

Welcome to my charge controller circuit pdf charge controller tutorials series. I have posted two version of my PWM charge controller.

If you are new to this please refer my earlier tutorial for understanding the basics of charge controller. This instructable will cover 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. 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. The MPPT controller is more sophisticated and more expensive.
