User manual

Over-excited energy is always displayed above the horizontal axis, and under-excited energy
below the axis.
The curve ends are always horizontal, meaning that the inverters will operate with the first set
point (1) below that power or voltage level and with the last set point (9) above that power or
voltage level.
The reference for the grid voltage is measured on the grid side of the master inverter.
The reference for the plant output power is calculated by the master inverter.
Reactive power generation will follow the specified set point curves when sufficient PV power is
available.
To define the PF(P) set point curve:
- enter up to nine pairs of values
- select under-excited or over-excited for each

To define the Q(U) set point curve:
- select an option from the drop down menu under Reactive Power Q
- enter up to nine pairs of values
- select under-excited or over-excited for each
