20 AMP SOLAR CHARGE CONTROLLER CIRCUIT DIAGRAM: Equalize key is charging fast when it comes to active position. If the battery is overheated, the charge is cut off. Charge the battery ( Battery keeps the charge constantly at low current to extend the life of the battery NOTE: It functions like the car’s charger )
NOTE: This circuit does not charge like 10 amps.
I connected the battery output to battery terminals by connecting to the 18v power supply (for a 12 volt battery ). The red led lights up continuously ( goes out when the power is cut off or when the panel is plugged in ).
When the battery is connected to the poles, turn the knob clockwise and counterclockwise to set it at 14.4 volts (for example, the battery will be adjusted to 13.8 depending on the value of the battery manufacturer). It is important to note that when the outputs are connected to the battery terminals, do not measure without being connected. When the battery is staked at 14.4 volts, the value continues to flash like a flash. The green LED flashes like a flash because the battery is charging. It continues to burn like a flash. it is a sign of the healthy operation of the system.
I tested the charge circuit with 20 amperes on the breadboard and there is no PCB drawing
