Independent channel configuration (default configuration)
This conguration is set at the factory and involves the use of the two
input channels (MPPT) in an independent mode. This means that the
jumpers (supplied) between the positive and negative poles of the two
DC input channels
12
must not be installed, and that the “independent”
channel mode should be set during the commissioning phase via inter-
nal webserver (step 4) or through the inverter display menu Inverter >
Settings > Input Mode”.
Parallel channel configuration
This conguration involves the use of the two input channels (MPPT)
connected in parallel. This means that the jumpers (supplied) between
the positive and negative poles of the two DC input channels
12
must
be installed, and that the “parallel” channel mode should be set during
the commissioning phase via internal webserver (step 4) or through the
inverter display menu “Inverter > Settings > Input Mode”.
