Hi there,
Just installed an ESS system with a Multigrid II 3000, and a Fronius Primo 5.0 (on AC-in) (I know the 1-1 rule, but's running on the AC-in, so no problem).
Fronius is communicating with the ColorControl, everything looks fine. Enabled "Fronius zero feed-in", but the "Fronius zero-feed in active" remains "NO". It only works if installed on the AC-Out?
Any clue?
Thanks!
Pedro
