Cable specification
Grid connection AC
Select the conductor cross-section according to the rated output current and the type of routing.
INFO

For outdoor installation, use UV-resistant cable. Alternatively, lay the cable protected from solar radiation.
The 4-wire AC connection (3L/PE without N) is only possible in symmetrical networks.
Take into account necessary reduction factors for ambient temperature and accumulation (when laying several cables without spacing).
Example: Ambient temperature 40 °C: Reduction factor 0.87 (according to DIN VDE 0100-520 / HD 60364-5-52).
