How to connect the photovoltaic installation to the switchgear in the building?

The discussion revolves around the proper connection of photovoltaic (PV) installations to building switchgear. Key points include the placement of phase wires from the inverter output, with suggestions to connect them behind the main switch or to a distribution block. The importance of protective devices such as RCDs (Residual Current Devices) and surge arresters is emphasized, particularly for the AC and DC sides of the inverter. The inverter is treated as a permanent power supply rather than a load, and adherence to standards like EN 60439-1 is recommended. The conversation also highlights the need for proper grounding and the potential implications of unauthorized installations on acceptance by utility companies.
