<div class="moz-cite-prefix">Charge controller failure = system
failure = customer sitting in the dark off grid.<br>
I would only use proven, UL listed equipment. Those are
ridiculous current ratings. You would need to wire that with 500
MCM cable.<br>
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. <br>
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.<br>
Finally, if you haven't done off grid or battery based systems
before, you should get someone on board with some long term
experience.<br>
