6. confi guration of input channel operating mode
The two input channels can be confi gured in two modes: independent mode and parallel mode.
The choice of input channel confi guration depends on the photovoltaic generator’s characteristics and
the inverter’s power and current limits. Refer to the system design documentation, or the documentation
on the CD, for the inverter input confi guration choice.
Warning! For the two channels to be used in independent mode, it is a NECESSARY condition that the
photovoltaic generator connected to each input has a maximum current and power below the channel’s
current and power limit.
Warning! For the two channels to be used in parallel mode, it is RECOMMENDED that the photovoltaic
generator connected to the two inputs has strings with the same number of modules in series and that all the
modules have the same installation conditions (inclination / orientation).
Refer to the technical data table in Appendix C to fi nd out the current and power limits of each input
channel for the various inverter models.
If the string’s current or power is above the current or power limit of the input channel to which it is
connected, the two input channels must be confi gured in parallel. This condition also concerns the
case where the photovoltaic generator comprises only one string with power above the inverter’s single
input channel power limit.
note: the inverters are pre-set in the factory with INDEPENDENT input channels.
If the conditions shown above are not met, consult the photovoltaic system’s designer immediately.
