Abstract: The stability of the power supply in Ghana and another part of Africa is a major concern to the community and shop owners. The need for alternative power supply support and switching of load between two power sources. The system will eliminate the need for manual intervention by sensing the main gridline supply and switching to a backup source. Automation charger over to the backup source will eliminate the delay and provide efficiency in production. The system will automatically switch back when main gridline power is restored back. the system uses a microcontroller as the main automatic changing over the process and other component consists of a power supply circuit consisting of a step-down transformer, rectifier, filter capacitor, voltage regulator, and sg3525 which perform the oscillation convention from DC to AC Renewable energy sources generating direct current will require inverters to produce the alternating current necessary for domestic and industrial use The design, construction, testing of this circuit, is satisfactorily in switching from mains supply to generator/renewable energy source(s) and vice versa
