Page 182: Startup
13 Function Description SMA Solar Technology AG 13.1.5 Startup 13.1.5.1 In Normal Operation: Active Power Ramp-Up The inverter works up to its maximum feed-in power via a ramp. This means that the inverter gradually increases the ratio of feed-in power per second by the value set in the parameter WGra.
Page 183: Shutdown
13 Function Description SMA Solar Technology AG If the AC power generated by the inverter falls below 5 kW, the inverter switches from feed-in operation to "Q at Night" operation. The inverter feeds in reactive power in accordance with the parameter settings. Since this status can also occur during the day, the DC switchgear remains closed at first in order to avoid unnecessary switching cycles of the DC switchgear.
Page 184: Remote Shutdown
13 Function Description SMA Solar Technology AG Tripping the fast stop The fast stop should only be tripped in case of imminent danger. Tripping of the fast stop does not entail fast discharge of the capacitors. If the inverter is to be switched off and properly shut down via an external signal, the remote shutdown input is to be used.
Page 185: Grounding And Insulation Monitoring
13 Function Description SMA Solar Technology AG Unlike active islanding detection, with passive islanding detection the utility grid is not actively influenced, but simply passively monitored. This involves monitoring the speed of the frequency change. If the power frequency changes by a certain amount in a certain time, a stand-alone grid is detected and the inverter disconnects from the utility grid.

This grounds one terminal of the PV array. Remote GFDI also enables automatic error processing.
Page 187: Insulation Monitoring Device
13 Function Description SMA Solar Technology AG If the Remote GFDI trips, initially a temporary error will be assumed and a motor drive will close the Remote GFDI after a defined waiting time. No external switch command is required to close the tripped Remote GFDI. The inverter can switch back to feed-in operation after a waiting time.
Page 188: Gfdi And Insulation Monitoring Device
13 Function Description SMA Solar Technology AG • If the parameter IsoErrIgn is set to On, the error message from the measuring circuit is ignored when the insulation resistance falls below the error threshold.

Page 190: Power Control
13 Function Description SMA Solar Technology AG Insulation monitoring should be performed in the operating state "MPP load operation". This will ensure that all parts of the system are included in the insulation measurement. Insulation monitoring To disable the grounding of the PV array, the parameter RemMntSvc must be set to On. This will open the Remote GFDI by means of a motor drive.

In addition, a minimum threshold for power frequency shortfall can be defined with the parameter P-HzStopMin, shown here at point D. If the power frequency falls below the grid limit, the inverter will shut down and switch to the operating state "Grid monitoring".
Page 192: Active Power Limitation Via Standard Signal: Wcnstnomanin Mode
13 Function Description SMA Solar Technology AG 13.3.2.5 Active Power Limitation via Standard Signal: WCnstNomAnIn Mode The active power limitation is set via an analog signal at the input terminals for the setpoint.
