 Power station total rated power (Pn) is the maximum on-grid power of the PV plant agreed by the
PV plant and the power grid company. Confirm this parameter value with the power grid company
and set it correctly.

Grid connection point voltage level (Un) is the voltage level at the connection point between the
PV plant and the power grid. Set this parameter based on the power grid status.
