Page 5: 10-Minute Average Value
2 Grid Protection Settings SMA Solar Technology AG 2.3.2 10-Minute Average Value The ten-minute average value is defined in the standard EN 50160 as maximum threshold for a continuous high voltage in the grid. If this value is exceeded, the inverter is disconnected from the utility grid. -

Page 7: Reconnection Time
3 Grid Failure SMA Solar Technology AG 2.6.2 Reconnection Time If a fault on the grid makes the inverter disconnect and the grid then afterwards stabilizes within the allowed voltage and frequency ranges, then the inverter is allowed to reconnect to the grid with this time delay. The reconnection time is usually shorter than the connection time, but it can also be the same time or longer than the connection time. -

3 Grid Failure SMA Solar Technology AG Phase Failure Detection The phase failure detection is used to determine the failure of one or more line conductors of the utility grid. In case of a grid failure, the grid relays open. -
Page 9: Settings Of Grid Management Services: Fault Ride-Through (Frt)
4 Settings of Grid Management Services: Fault Ride-Through (FRT) SMA Solar Technology AG 4 Settings of Grid Management Services: Fault Ride-Through (FRT) The inverter is equipped with the Fault Ride-Through function for both undervoltage (LVRT) and overvoltage (HVRT/ OVRT) situations. Although the FRT function belongs to grid management services, it is stored in the inverter. The FRT function is set to cope with voltage dips down to 0% UNOM without time limit. - Page 10 4 Settings of Grid Management Services: Fault Ride-Through (FRT) SMA Solar Technology AG For reactive power feed-in, the positive and negative sequence components are considered separately. The half-cycle root-mean-square values of the positive and negative sequence components of the grid voltage during the grid fault are compared with the average root-mean-square values before the fault.

Default Settings 5.1.1 Selecting the Control Modes for Reactive Power Provision Reactive power references can either be given as a direct reference for reactive power (Q) or as an indirect reference via the power factor (PF). -
Page 14: Night Mode
5 Settings of Grid Management Services SMA Solar Technology AG 5.1.2 Night Mode The system with an inverter provides reactive power also in night mode. Therefore, the inverters are not switched off after sunset. Information: If no primary energy source is available, only the control modes 1 to 5 can be used for reactive power provision. -
Page 15: Nominal Voltage
5 Settings of Grid Management Services SMA Solar Technology AG 5.1.6 Nominal Voltage This parameter refers to the nominal grid voltage at the point of common coupling. The parameter is used to scale the grid voltage for the control modes where the grid voltage is the independent variable, i.e. for Q(U), PF(U) and P(U). If no external energy meter is used, this parameter should have the same value as UNOM in the protection part of the grid code file. -

5 Settings of Grid Management Services SMA Solar Technology AG 5.2.5 Active Power Ramp Rates The active power is ramped according to these setting whenever the external setpoint for active power is changed. Note that two parameters are available: one for decreasing and one for increasing setpoints. -
Page 17: Control Modes
5 Settings of Grid Management Services SMA Solar Technology AG Control Modes The general approach for the control modes is based on the structure in the technical report of the standard IEC 61850-90-7 (see the figure below). Up to five parameters are used to program the local modes depicted above. The parameter RmpTmsPT1 is the rise time from 0% to 95% (equal to 3τ) for the low-pass filter applied on the independent variable (e.g. -

5 Settings of Grid Management Services SMA Solar Technology AG 5.3.8 P(V) – Active Power as a Function of Grid Voltage This control mode uses the grid voltage to generate a threshold for the active power so that the grid voltage can be controlled at the point of common coupling. - Page 20 5 Settings of Grid Management Services SMA Solar Technology AG Figure 6: Parameterization of frequency control Position Explanation Typical programming of the FP_of_f characteristic curve when hysteresis is not required, e.g. as per VDE AR-N 4105. Thus, the two characteristic curves in the reference table contain equal co-or- dinates (x, y).
