    Solar power battery charger

    I want to make a solar power battery charger with a PIC, i look for schematic or information about this, I havent'understand becouse in some schematich for limiter the charger current a mosffet makke a short-circuit on the solar pannel instead of open a battery circuit

    Can you post the schematic you are looking at? It will be helpful.

    Solar power battery charger

    I think it is not a short circuit, but it is a electronic load for the solar pannel in case of the battery is fully charged.

    Re: Solar power battery charger

    I've built a solar charge controller using a PIC microcontroller, simply used an LM317 regulator and PWM to give constant voltage and float charge to a lead acid battery. I used the built in ADC of the 16F877 to sense battery voltage and also current across a shunt resistor.

    Since he joined in 2004, he has just 44 post in Two years. His last post was on Nov 10th 2006. Do you expect him now and put up his schematic here? If he does, wouldnt it be a real miracle...But hope so...
