    PIC16F73 based 50A PWM 12v-24v-48v auto solar charge controller with HEX and PCB

    Pic16F73 50A PWM solar charge controller
    12V,24V and 48V auto battery detect (connect battery first and then solar)
    conman anode seven segment display (display bat-V, Chg-Amp, and overload )
    short circuit and overload detection
    optional relay output for external battery charger (when solar not available or not provide sufficient currant to battery external charger connect through relay, auto detect)

    I design direct PCB not a Schematic so don't ask me for schematic....

    I am building your charge controller but what is the resistance of the shunt and what is the unmarked component that is on the BAT+ pad

    Thanks
