Hello, I hope you are doing well.
During the installation of an ESS on my Multiplus 24/2000/50, I need to select a grid code standard. However, regardless of the grid code I choose, I receive the warning: “This device is not equipped with internal interface protection”. The only exception is when I select “Other: not compliant to any grid code standard”, but in this case, I cannot inject energy into the public grid. As a result, the photovoltaic inverter automatically reduces its output power.
Can someone help me resolve this issue so I can inject the surplus energy?
