Setting SMA ShadeFix


Qualified person

You can set the time interval in which the inverter has to determine the optimum operating point. If you do not want to use SMA ShadeFix, you can disable the feature.

The basic procedure for changing operating parameters is explained in another section Changing Operating Parameters).

Procedure:

  • In the parameter group DC-side > DC settings > SMA ShadeFix, set the parameter Time interval of SMA ShadeFix and set the required time interval. The ideal time interval is usually six minutes. This value should only be increased if the shading situation changes extremely slowly.

    The inverter optimizes the MPP of the PV system at the predetermined time interval.

  • In order to disable the SMA ShadeFix feature, in the parameter group DC-side > DC settings > SMA ShadeFix, set the parameter SMA ShadeFix switched on to Off.
