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

    pls sir the pin connection for the above circit

  14. pandian

    Hai, Good Morning
    I have the solar panel 300watts,
    how many voltage battery can use to charge.
    thanks,,,,,,,

  15. pradeep

    Dear sir i need solar charge controller skematic with battery low cut off high cut off using ic lm324…

  16. Younas

    left side pin # 6, Top 12, Right from top to down 10, 1, 4, 11 and down pin # is 7 for your kind information.

  17. sid

    very good circuit i think i will use it for my project

  18. anas

    and can you tell how much power we needed from the input plz ?

  19. Mithil

    Will it work for 7.2 Ah , 12 volt battery ?

  20. Prem

    In here I need to know how set values to VR1. I think you will send immediate responce.
    Thank you

  23. Kadreus

    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

    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.
