Solar battery charger with overcharge protection

This circuit is formed maintain one’s position voltage from solar cell with , shunt regulator circuit. For protect voltage not too until much destroy battery. Because of something charger too much.

Solar battery charger with overcharge protection

The D2 be for protect current flow turn back from battery during nighttime. The circuit maintains one’s position current the few , for feed give the circuit randoms voltage battery.

Which have IC LM723 be main part by may use battery model acid general lead. That want power supply give the circuit all the time , thus should choose battery at have many capacity such as , 40Ah sizes etc. The detail is other , see in the circuit.

Note:

This circuit is not design PCB. If you do not want to design own PCB. Or use universal PCB Board that difficult.
I would recommend a 7 Amp solar Charge Controller

  6. I want to set up the same circuit. I think you have done a great job. Can you write lm 723 integrated pin connectors? We need to know where you’re going, which ends when the connection?

    • Hello Kadreus,

      Thanks for your visit. I am happy that you feel interested in this circuit.

      But I am so sorry. I cannot draw a pin number of 723 IC. It comes from an old book.

      I think in the future I can update it.

      Hope you can wait for me and continuously visit my site.

      Sincerely
      Apichet

  7. I need a circuit to charge a lithium phosphate 12 volt DC battery. It needs to charge with a 5 amp constant current and an adjustable over voltage shutoff.
