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:
If the conditions shown above are not met, consult the photovoltaic system's designer immediately.
