“Grid Connected

PV Systems with Smart grid functionality”. It solves the problem of shading to the available

NTNU PV modules which is sensitive to the exiting central inverter system topology by

proposing a PV system which is more efficient and reliable. This thesis is focused on the

design of the PV-grid connected inverter power stage that supports the proposed PV system

under study. As part of the NTNU renewable energy laboratory project, a single phase 1kW,

230V, dual power stage inverter is designed. The important parameters required for inverter

stage including input inductance and capacitance, DC –Link capacitance and LCL filter were

designed.
