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 (I_DCmax) per MPPT and the maximum DC current per DC input (I_Stringmax) 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.
