Other settings

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.

Compatibility of type A RCD

NOTE! This menu item depends on the inverter power and is not displayed for all inverters.

If this function has been activated, type A RCDs can be used as residual current protection equipment. In such cases, the inverter shuts down when the residual current becomes incompatible with a type A RCD.

If the function is deactivated, a type B RCD must be used as residual current protection equipment if an RCD is stipulated.

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
