There is insufficient PV power available for feeding energy into the grid, and simultaneously, no power has been requested from the battery. This results in a short-term interruption while the inverter repeats its start-up routine. This is often displayed routinely early morning or evening due to low insolation and may not indicate a fault.

This code indicates either a compatibility error, such as after a PC board replacement, or an invalid configuration of the power stage set. This prevents the inverter from feeding energy into the grid.

The inverter is unable to feed energy into the grid due to either a sticking grid relay or an excessively high neutral conductor ground voltage. The neutral conductor ground voltage must be less than 30V for safe operation.

This warning message indicates that no energy has been fed into the grid by the inverter during the last 24-hour period. This can occur if conditions for grid feed-in are not met, preventing the system from operating as expected.

When the inverter's internal temperature becomes excessively high, it initiates power derating to protect components, displaying a warning message. The system automatically reduces output power until temperatures return to a safe range.

This warning message indicates that the photovoltaic (PV) system has not fed any energy into the grid over the last 24 hours. This typically suggests an issue with PV production or grid connection conditions.

This warning indicates that one or more PC boards within the inverter are not compatible with each other. This often occurs after a PC board has been replaced with an incorrect or non-matching version.
