Sunny boy sb 3000 manufacture 2012 ac coupling
Yes I think the Sunny Boy will have to include frequency shift in the spec because they were designed for the German market and in 2012 the German grid code required it.
I have Steca inverters (also German) manufactured in 2011 and it is part of their spec too. Upper limit for normal operation is 53 Hz and I have the 3 frequency settings in VE Configure set to 53.1, 53.2 and 53.3 Hz (they have to be different). In loss-of-grid/island mode the shutdown on over-frequency works correctly to prevent excess PV generation.
Thank you.
My mistake, the settings in my ESS Assistant are 51.1, 51.2, 51.3 Hz, not as originally stated above.
You do not say what country you are in, here is the table for my StecaGrid 2000s which may help in setting up the Victron eqpt to work with your Sunny Boy:
