Selecting PV inputs
If the inverter's DC inputs are not fully occupied, distribute the input assignment in accordance with the following tables: Make sure that the maximum input current (IDCmax) per MPPT and the maximum DC current per DC input (IStringmax) are not exceeded in the process:
INFO

Only connect PV modules of the same type to an MPP tracker, i.e.:
- same manufacturer,
- same type,
- same performance,
- same size.
