Arduino Solar Charge Controller Circuit Diagram. Thus the maximum input range is 4 95v to the 32v for both solar and adapter. Charge regulator with power box connections to regulator inside the box.
The arduino tries to maximize the watts input from. Is the input of the system which is the power supplied by the solar panel the fuse f1 and tvss represent the protection network against any high current that could happen to the circuit. Play video welcome to my solar charge controller tutorials series.
The voltage divider network r1 and r2 are used to scale down the voltage provided by the solar panel vpv so that the maximum voltage supplied to the arduino analog input a0 doesn t exceed.
Finally i made a pwm charge controller. If you are new to this please refer to my earlier tutorial for understanding the basics of the charge controller 1. There are many charge controllers available in market but ordinary cheap charge controllers are not efficient for use with maximum power from solar panels. Example 5 5 transistorized solar charger controller circuit above i don t understand the pcb diagram looks to me like one of the bc547s is shorted in the center of the board.
