The topic has probably been discussed many times. But I couldn't find a complete answer anywhere. Ground installation 10kW. 2 thongs. 24x 425 W panels. Inverter mounted under the panels. Unfortunately, the installation is far from the 3-phase socket. You need 120 m of AC cable to connect the inverter to the grid. What earth cable to install. Will 5x6mm² be enough, or do I need to throw something bigger into the change. Due to the distance and price of copper cables, I'm thinking about aluminum cable. If so, what section?
