Analysis characteristics of on/offgrid tie inverter and implementation in microgrid

One characteristic of microgrid is possible to be integrated with the public electricity network (PLN/grid) or work independently of the public network. Additionally on microgrid is also possible to supply excess power to the grid and still be able to supply power to local load even when disconnected from grid. Not all inverter devices can be used on a microgrid, associated with some of the criteria that must be met. How do the characteristics of on-offgrid tie inverter (GTI on-off) and how to build microgrid using on-offGTI became topic of this research activity. Based on results of testing, on-offGTI can be used on microgrid, with ability to supply power to network when excess power or supplied from network at the time of power shortage. As well as on-offGTI is able to work independently when there is no power from network.
