Configuration SHP FLEX-US
Qualified person
The SHP FLEX-US can be flexibly adjusted in terms of power and AC voltage and current. As a result, the SHP FLEX-US can be optimized for repowering purposes and used variably.
After commissioning the SHP FLEX-US, the following parameters must be set so that the product can be used as a replacement for existing devices.
If the grid protection limits have already been configured using a country data set or beyond, this does not have to be done again. The product works with standardized values based on the respectively set nominal voltage or the set maximum current.
If the country data set is changed or set again after configuring the following parameters, the Nominal system voltage parameter must be set again.
If required by the grid operator, there is the option of having the parameters for apparent and active power limitation locked by Service via remote access. To do this, a suitable connection with external access to the grid must exist. Further information is available from Service.

Further parameters
Name | Value to be set |
|---|---|
Minimum voltage input | PV voltage to start the feed-in operation. Formula: AC voltage x 1.55 |
Critical voltage to end feed-in | Minimum PV voltage to which the MPP tracker tracks down. Formula: AC voltage x 1.4 |
Disconnection limit for leakage current | Disconnection threshold for the leakage current. Formula: Set power in kW / 100 |
Disconnection limit for the lagging component of the leakage current | Disconnection threshold for the lagging component of the leakage current. Should be set to the same values as Disconnection limit for leakage current |
