Other settings
Parameter | Explanation |
|---|---|
Isolated network detection | Activate/deactivate isolated network detection. Ensures that the inverter does not switch on or off in the event of supply voltage errors. |
Residual current monitoring | Activate/deactivate residual current monitoring. When the function is enabled, the inverter detects the array fault current. |
Shadow management | If PV strings are in partial shading, the PV string affected no longer achieves its optimum performance. If shadow management is activated, the inverter adapts the MPP tracker in such a way that it can operate at maximum possible performance. |
Shadow management interval time (s) | Set the interval of the MPP tracker sampling rate |
Insulation resistance (kOhm) | If the value established for insulation resistance is less than the preset value, the inverter is not connected to the grid |
Leakage current limit (mA) | Limit value for leakage current detection. If the value established is higher than the preset value, the inverter will shut down. |
Limit for unbalanced voltage (%) | Setting the threshold value for DC voltage asymmetry |
Dynamic grid support (FRT) | Dynamic grid support (FRT = Fault Ride Through) | |
| Positive sequence K factor | Settings for uninterrupted cycling through grid faults FRT (Fault Ride Through) |
Negative sequence K factor | ||
Monitoring of supply voltage | ||
Undervoltage ride through (V) UVRT | ||
Overvoltage ride through (V) OVRT | ||
Grid support mode | ||
Limited grid support (%) | ||
Irregular voltage change (%) | ||
Overvoltage protection monitoring | Activate/deactivate monitoring of the internal overvoltage protection modules (SPD - Surge Protective Device). |
AFCI function | Activate arc detection. |
Reset arc errors | Reset arc errors. This should only be done if the cause has been established. |
Arc error sensitivity adjustment value | Adjust the sensitivity (default value: 40). |
Arc detection adjustment value | Adjust the value for arc detection or use the default value (default value: 16) |
Current arc intensity adjustment value | Adjust the value for current arc intensity or use the default value (default value: 800) |
Average arc intensity adjustment value | Adjust the value for average arc intensity or use the default value (default value: 200) |
