The banks are already switched. One is 4, the other is 3.

I can't get the string page to display.

Banks of batteries are switched?

I've purchased the Magnum 3012 hybrid inverter so I'm committed to a 12 volt bank.

But you're not committed to 12v on the pv array..yet. If you're paralleling 1250w, you're going to be hitting upwards of 80a. That's some big wire. Of course, you can series them up to 80v, which I guess would end up being around 72. Could be a bit tricky wiring that up. I'd sure be looking at a controller with much higher input voltage.
