Reducing The Attenuation Of Ripple Control Signals; Setting Sma Optitrac Global Peak - SMA SUNNY TRIPOWER 15000TL Operating Manual

8 Configuration
Procedure:
1. Ensure that the firmware version of the inverter is at least 2.62.04.R. If necessary, carry out a
firmware update.
2. Select the parameter Fallback act power lmt P in % of WMax for absent act power lmt
and set the required percentage.
3. Select the parameter Operating mode for absent plant control and set to Use fallback
setting.

Reducing the Attenuation of Ripple Control Signals

By setting certain parameters, the attenuation of three-phase parallel ripple control frequencies
ranging from 1,000 Hz to 1,100 Hz can be avoided. The parameters must only be set in
consultation with the responsible grid operator.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.3 "Changing Operating Parameters", page 40).

Setting SMA OptiTrac Global Peak

For partially shaded PV modules, you should set the interval at which the inverter is to optimize the
MPP of the PV system.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.3 "Changing Operating Parameters", page 40).
