  3. Multiplus with Sunny Boy 4.0

    StingrayZA posted a topic in Inverters
    Hey guys, I have a couple of questions and I thought this will be the perfect place to ask them. I have a Sunny Boy 4.0 Inverter on my AC Out on my Multiplus. When the battery reaches 100%, the multi shifts the frequency to stop output from the SMA, but it doesn't comply and then trips. I've read on some posts that the SMA phase shifting only works if the SMA is in 50Hz Off Grid Mode (Same as MG50 on Fronius). Now my question is what will explode if I change the grid code on the SMA to this island mode as it is essentially an island with the multi performing the anti-islanding functions.
