Development of Battery Charge/Discharge Regulator for Photovoltaic Systems

This work present the development of a battery charge/discharge regulator for photovoltaic systems. The system is designed to operate at 12V and accept solar panel up to 100W. The charge/discharge regulator is an analog one with protections respectively against battery deep discharge and overcharge, thermal drift, short circuit and polarity inversion. The proposed regulator has been realized and tested in a solar home system (SHS) composed with AC lamps and DC/AC inverter
