Feed-in above export limit

This symptom means more active power is fed into the grid at the point of connection than the export limit allows, even though export limitation is switched on. It shows in the system logbook as a message that supplied power has exceeded the permitted value several times, or that an inverter does not respond to active power limitation. On export control monitoring screens, a red status bar means exported power is above the limit, while yellow means it is inside the guard band below the limit. A short exceedance after a sudden load change is normal because the control cannot fully prevent it, but it is limited in time; repeated or lasting exceedance points to an export control fault. Check the feed-in or energy meter first: confirm it works and is wired correctly, since a failed or wrongly installed meter breaks the control loop. If the meter is fine and the message keeps coming back, check the inverter active power operating mode so it follows the external or system control setpoint. If an inverter does not respond to limitation, the controller curtails the other inverters harder to stay within the limit; if the exceedance message also appears on the same day, there is a real fault. Check the guard band or negative limit settings too: they give the control a safety margin against load steps and meter inaccuracy.

<!-- review notes

• sentence 3: support check: partial - Red over the limit is stated, and yellow is in the guard band between set point and limit, but the guard band is not stated as 'below the limit' in those exact words (it is between set point and limit, which implies below).
• sentence 4: support check: partial - Short exceedance after load change being normal and time-limited is stated, but 'repeated or lasting exceedance points to an export control fault' is only supported for the SMA repeated message case, not generally.
• sentence 5: support check: partial - Checking the meter works and is correctly connected is stated, but 'first' ordering and the claim that a failed meter breaks the control loop are not stated.
• sentence 8: support check: partial - Guard band as safety margin including measurement accuracy and negative value for load steps are stated, but the passages don't frame it as a troubleshooting check, and meter inaccuracy applies to the guard band only.
• sentence 4: review: partial - The FIMER note supports that a short exceedance after a sudden load change cannot be fully avoided and is time-constrained by the control, but the general claim that repeated or lasting exceedance points to a fault rests only on the… -->
