If only one PV generator having a
short circuit current lower than
"Max. input current" is used, only
one of the two inputs of the
inverter may be used.
In this case it is necessary to
choose „independent‟.
If only one PV generator which
short circuit current exceeds
"Max. input current" is used, The
two inputs of the inverter must
operate in parallel.
The parallel connection of the
cables must be executed outside
the inverter by means of
adequate terminals.
The inverter must be set as
„parallel‟
If the two MPPT are used in
parallel, avoid the execution of
the parallel connection trough the
connectors of the inverter.
This could cause the overheating
of the internal cables and lead to
production losses and/or failures.
