: It is the intention of a group of words that are multilevel inverters transformer less inverters for solar systems every one of the latest topologies was introduced based on the solar power systems principle and needs only four power switch and the unidirectional equipment (diode). One condenser and a tiny strainer at the final stage the main favor of the latest converter topologies was the minus pole of the solar power system is straightly attached to the grid and no discharge current. Reactive power damages the capacity The final AC voltage period is same to the starting DC-voltage a total detailing of the working principle with drone method, and examination imaginative comparisons are available to show the degree and quantification of the every topology in word to word form
