Saw a new controller available from Swiss manufacturer Studer:
Specs look interesting, it has 2 independent MPPT trackers built in and you can wire the array as 2 sets of 600Voc, or a single series-wired 900Voc array. 5 year guarantee and programmable ground fault detection.

Studer seem to have distributors in most of the world except north america:

    Thanks stephendv for posting info on this CC.

    It is stout, indeed. But, guess that they are not available for purchase in the US. Probably very expensive.
