The purpose of this paper gives a literature study about multilevel inverter topologies and to investigate the properties of these topologies. Especially the voltage balancing problem that is common with multilevel inverter will be investigated and also the advantages and disadvantages of the multilevel inverters will be compared to two-level inverters .It also includes an evaluation and comparison of the different topologies and a simulation presentation where two MLI topologies have been tested in simulation to investigate voltage balancing solutions and to compare with a two-level inverter. The comparisons include generated THD's, harmonic components and losses.

The future electricity sources in India must be green energy, flexible, accessible and sustainable. The Educational Institutions are a back bone of any country, which are planning major role in development of nation. In India maximum Educational Institutions have only day scholars and maximum electrical energy demand in Institutions between 9.00 AM to 4.00PM. The government of India introduce many programs for green campus development across the country, under this program solar power plant will be setup for fulfil the electrical demand in day time. The educational institution will implement the Microgrid in ON-Grid mode for fulfil the electrical demand from solar PV Power Plant. In this paper we are studying the major challenges for microgrid implementation in Educational Institutions in India.
