Setting SMA OptiTrac Global Peak
Qualified person
For partially shaded PV modules, you should set the interval at which the inverter is to optimize the MPP of the PV system. If you do not want to use SMA OptiTrac Global Peak feature, you can deactivate 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 > OptiTrac Global Peak, set the parameter Cycle time of the OptiTrac Global Peak algorithm 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 deactivate the SMA OptiTrac Global Peak feature, in the parameter group DC-side > DC settings > OptiTrac Global Peak, set the parameter OptiTrac Global Peak switched on to Off.
