Safety-relevant parameters
You can change the safety-related inverter parameters of your PV plant using the
Sunny WebBox. Incorrectly set parameters can cause connected inverters to deactivate.
This results in yield losses. Usually, these safety-relevant parameters may only be changed
upon consultation with the electric utility company into whose grid you are feeding. In case
of doubts, contact your electric utility company.
