Hey Everyone, hoping you can help me out....
Currently have a Multiplus II 48/3000 hooked up to a 150/45 Victron MPPT attached to a 2360w Solar Array. I'm wanting to expand the system by adding another 3kw solar array and am thinking to do so by means of an AC Coupled Fronius as the intension is for this array to be predominantly for direct use. Being that I live in South Africa where their is frequent load shedding I intend to put the Fronius on the AC Out side of the Multiplus so I don't loose the benefit of it when the Grid is down.
Question I have is... With the fronius on the AC-Out (Essential loads) side of the Victron, what will the max PV power that will be able to be fed back to AC-In (non Essential Loads) when the Grid is up? The Fronius will have the ability to provide 3kw and the MPPT around 2.4kw but considering the Multiplus is only a 48/3000 will I be limited to only passing 2.4kw back to non-essentials or will I be able to feed back the full 5.4kw as a result of the Fronius provided PV already being AC (so Victron doesnt have to invert it)?
Or would the full benefit of the Fronius PV yield only be possibly if I put it grid side of the Victron (ie on the non-essentials circuit)?
