This thesis will assess the transient over-voltage (TOV) generated by grid-tied solar photovoltaic (PV) inverters when they are disconnected from the electric grid. While these events have been somewhat recorded in the field, it is has become necessary to reproduce them in a laboratory in order to appropriately analyze their distinctive over-voltage behavior. Therefore several three-phase commercial and split-phase residential inverters from various manufacturers were installed and tested in Southern California Edison's Distributed Energy Resources (DER) Laboratory. Analyzing the test data will provide a better understanding regarding the severity of the over-voltage and its adverse effects on both utility and customer equipment. Recommendations will be given to determine what standards or practices would need to be implemented when referencing the inverter TOV as well as what prospective mitigation techniques could be used to fulfill these requirements.
