Multi-Master System
In this configuration there is no physical link between the photovoltaic fields in each module. Each
DC disconnecting switch is practically independent of the others.
The following table indicates, in the first column, the position of the switches, in the second
whether the photovoltaic field is connected to the module, and in the third whether it can be
removed or inserted in the seat.
