Charge controller failure = system failure = customer sitting in the
dark off grid.
I would only use proven, UL listed equipment. Those are ridiculous
current ratings. You would need to wire that with 500 MCM cable.
If you look, you'll notice reputable brands like Midnite Solar, Outback,
and Blue Sky Energy, do not exceed 100 amps. You just stack more
controllers for bigger systems. This has numerous advantages, including
redundnancy, so a single controller failure does not = system failure.
It also means various sub arrays have independent MPPT. Another
advantage is that many of these controllers can run at higher array
voltages, so fewer parallel strings.
I don't even think that controller has MPPT, so you would have to find
12 or 24 volt modules; regular 60 cell modules would not work.
Finally, if you haven't done off grid or battery based systems before,
you should get someone on board with some long term experience.

Greetings Wrenches,
We're considering a new charge controller for an upcoming project that
offers a wide range of operation and customization. Has anyone had
experience with this product? General specs and link below:
Sollatek - Solar Control Centre/ Solar Charge Controller
12/24/or 48V
10-100V Voltage Range
90-960A Max Charge Current
