#### Abstract

This paper proposes the design of a monophasic inverter connected to a residential network by applying Z-Source topology. The proposed models were verified in normal operation “STC” and under short circuit conditions “SC”. The system is presented as coupled to a network without a transformer and with minimum electrical components. The tolerance of the overcurrent or short-circuit current is also analyzed on this topology. The signal’s power is conditioned to find the MPP of the PV panels. Its architecture will be outlined, described and simulated in Matlab’s Simulink®. In order to verify that the design is working properly.
