A completed E.9 sheet contains information that is necessary for the EZA controller and the telecontrol system. All relevant sections are listed below.
Page 1:
- System name
- Agreed connection active power for feed-in PAV,E: Active power of the customer system agreed between the grid operator and the connec
feed-in at the grid connection point. Should normally correspond to the sum of the maximum AC active power of the inverters. Is used as a reference value for Q(P) characteristic curve, whereby 1.0 Pmom/Pb inst is equal to PAV,E. - Reference system present: must be taken into account when configuring the reactive power control if necessary (see table on page 5 below)
Page 5:
- Static voltage maintenance:
- Reactive power setting range: maximum or minimum reactive power that the system must be able to generate
- Reactive power setpoint and method: Reactive power method (in accordance with VDE-AR-N 4110/4120), which must be configured in the digital twin.
- All settings below the displacement factor cos φ must currently still be set by Amperecloud.
- Mixed systems: if the points are set at different locations, 2 grid analysis devices must be installed (NAP and EZE)

- Agreed supply voltage of the network UC: Reference voltage when using the Q(U) characteristic curve
