7.2.2.4 Parallel input connection
The DC inputs can also be connected in parallel. Only strings with identical MPP voltage can be connected in
parallel (Un

m
).
The maximum permissible rated current (DC) doubles with parallel connection of both MPP trackers.
In case of a parallel input connection, MPP trackers A and B must be bridged. If input 1 is connected to input 2 and
input 3 is connected to input 4, then there is no parallel operation! The maximum rated current (DC) should also
be observed. Parallel operation is automatically recognized by the inverter.
