Just to put a few things aside. NRS 097 is all about the interconnection between a SSEG and the grid, where the SSEG can be a generator, inverter etc. Now there is a requirement for NRS 097 stating that live and neutral to the grid must both have 2 series connected automated disconnect switches. Live should have 2 automated series switches controlled by the inverter as well as the neutral. There should also be a neutral earth bonding relay for islandng. If this is not additionally installed on the installation, no setting can make the setup NRS 097 complaint. If the inverter states NRS compliance it doesn't mean the installation is. From history and seeing installations, there are very little installations actually NRS compliant. Victron (newer generations such as the multilus ii) and some other transformer coupled inverters is the only brands i know of that have all the necessary automated and bonding switches inside. With no external switches required. This is the exact reason why cape town now requires electrical engineer approval as well as approval at the council.
