Solar panel controller circuit.

Parts list for the low drop solar panel charger circuit. R1 r2 n a see text. After finishing the circuit you need to set the upper and lower limits. The shown solar panel regulator circuit is framed as per the standard mode of the ic 338 configuration.

16w includes power dissipation of d3 typical dropout voltage. 7 to 14v adjustable not recommended for 6v applications max power dissipation. 18 to 20v output voltage range. The pot or the preset is used to accurately set the voltage level that may be considered as the safe value for the battery.

50w 4a 12v nominal open circuit voltage. This is the driving circuit of the diy automatic solar charge controller. Q3 2n3904 or the majority of small signal npn. The input is given to the shown input points of the ic and the output for the battery received at the output of the ic.

The 5v relay is the main.
