Permitted cables AC cables with the following design can be connected to the AC terminals of the inverter:
- Copper (Cu) or aluminum (Al): round, solid
- Copper: round, stranded, up to conductor class 4
Cu / Al Cu
AC & DC = copper cables (Cu)
The following wire combinations can be used for wiring.
Select a sufficiently large cable cross-section based on the actual device output!
