Some properties of a PV inverter grid connection can cause the grid voltage at the inverter to increase and exceed the permissible operating range if the feed power is high. If this occurs, SMA grid guard, an independent disconnection device integrated into the inverter, will safely disconnect the inverter from the grid.
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
If the inverter records that the 10-minute average exceeds this voltage limit, or if the 260 V limit is temporarily exceeded, it will switch off immediately. The inverter will display a grid error message if this occurs.
The average grid voltage (UAC) at the inverter as measured over a period of 10 minutes is limited to a maximum of 253 V in Germany according to DIN VDE 0126-1-1. If the inverter records that the 10-minute average exceeds this voltage limit, or if the 260 V limit is temporarily exceeded, it will switch off immediately.
