Author’s explanation about the 741 Opamp circuit;
FRIENDS As you know, the charging circuits spend some of the current as heat in the transistor. This circuit transfers the current to the battery with very little loss. Since the energy coming from the solar panel is limited, I designed this circuit, it works very well. It can be used in the role I use. Opamp feet that are not shown in the diagram are empty
Adjusting the charging circuit; P1 will be adjusted to take the Mosquette to the cut. P2 Sets the LED to light while the battery is charging. When the battery is full, the led will turn off. P3 Battery max. 14.4v to be adjusted according to filling voltage
Note: The power of the diodes used in the circuits + or on the line should be determined according to the current drawn and the mosfet transistor should be connected to the cooler according to the current drawn.
