Configuration Of Independent Or Parallel Input Channels - ABB REACT 2 Series Product Manual

C
onfiguration of independent or parallel input channels
All input parameters that must be met for correct inverter operation are shown in the "technical
data" table.
All versions of the inverter are equipped with two input channels (therefore
with double maximum power point tracker MPPT) independent of each
other, which can however be connected in parallel using a single MPPT.
Each channel must be connected with strings of PV modules having the
same type and number of panels in series; they must also have the same
installation conditions (in terms of orientation and inclination).
When connecting the two input channels in parallel, you must comply with
full power of the inverter output on a single channel.
The dual MPPT structure however allows management of two photovoltaic
generators which are independent of each other (one for each input channel),
and which may differ between themselves with regard to installation
conditions, type and number of photovoltaic modules connected in series.
A necessary condition for the two MPPT to be used independently is that
the photovoltaic generator connected to each of the inputs has a lower
power than the power limit of the single input channel and a maximum
current lower than the current limit of the single input channel.
