    helo,i need help on figuring out circuit for solar panel,battery,and load,charger regulator.
    we have in pic
    [​IMG]

    solar panel,battery and load.

    The blue thing are relays,the connection is drawn because i dont know if one can do job or i need 2.
    so,i want solar to charge battery and load,when battery is full relay disconnects all connection .
    the battery circuit is running when solar is getting less power than needed for load by relay to .

    is this possible,if is then how,
    thanks

    I would not use relays, but install a diode inline with the solar panel. That would allow the battery to charge from solar during daylight, but also stop discharging current in the opposite direction.

    If you are dealing with high wattage solar panel, or a pv array the regulator and relay might be the way to go.

    From first glance, looks like you have a small panel charging a small radio.

    I know about the diode ,did not draw for simplicity of pic.
    I think i need to use relays and or LM311 or LM2596

    yes small portable radio

    How much current does the solar put out?
    What kind of battery?
