good evening dear forum
i have an ESS configured with the german grid code with internal NS protection.
my grid exceeds about 5-10x daily the 10min above 253V. however, the grid voltage is hardly above 255V, only in exceptional cases up to 259V.
as a result, my multiplus disconnects from the grid accordingly 5-10x daily.
questions:
1. do i have to worry about the relays involved because of the number of switching operations over the years?
2. can i increase the value in the grid code to 255V (i am in portugal, not in DE and basically not feeding in either), or will this have negative effects?
THANKS
