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....
