Quatro 10k with Multiplus 2

I am currently running a 10kv Quattro with is being driven to overload as I am adding extra loads, I have a very small Grid connection (3Kva) this has only been used very rarely for Battery charging. I want to fit an additional Multiplus 2 in series onto the Quattro input, and also use the multiplus 2 anti islanding facility to use the grid connection as well. is their any potential problems with this setup
