<span>To power remote area telecom where grid supplied electricity is unreliable, an alternative exists in the form of renewable energy sources. These sources mainly rely on the weather condition of a particular area for their source of power. To overcome such problem, hybridization of energy sources are prefered. Hybridization of solar-wind systems use a separate converter for each source thus leading to a complex, bulky and less efficient system. This paper presents a single renewable power

It uses cuk and sepic converter topologies to form cuk-seic interfece. These systems also use battery backup to store excess energy and to make best use of their operating characteristics. Performance comparison between a cuk-sepic renewable power interface with and without MPPT using MATLAB/SIMULINK is presented. A detailed componentwise analysis is also done to calculate best efficient interface. It is found that the cuk-sepic interface with MPPT is efficient. A lab level model for cuk-sepic interface is developed and tested. The experimental results proved the effective operation of a single renewable power cuk-sepic interface with MPPT. </span>
