magnetek aurora inverter

Has anyone used one of these? It can isolate arrays of varying orientation or string size. Wondering how they worked out.

They look very interesting with their double MPPT for separate series strings of different orientations. Sunnyboy have Multi-string technology like these with 2 & 3 MPPT in Germany, but they are transformerless & won't pass the isolation tests for our RCD ( residual current devices ) (safety switches ) for our Australian Standards so they aren't listed yet. I wonder how much they are, maybe it would be cheaper to buy 2 separate inverters. Can you find anyone who sells them?
