Display of real-time values
- Select „Now“ display mode (see chapter entitled „The Display“)
- The first display function of the “Now” display mode will appear
* Optional - If the necessary option card is not present, then the letters “N.C.” are
displayed.
Module voltage ... Voltage (in volts)
currently present at the solar modules
The voltage displayed whilst power is being fed into the mains corresponds to what is
known as MPP voltage (MPP = maximum power point). The FRONIUS IG always
maintains the module voltage within the range that allows the maximum possible power
to be obtained from the solar modules. This ensures that your photovoltaic system is
always operating at maximum efficiency.
