Best arrangement for 3x panels + Renogy 60A Rover Controller

[zzmtc]

Hi folks,

I'm looking to buy qty 3 Blade bifacial panels (SEG-395-BMA-BG). Voc front is 49.3 and Voc back is 48.9. The Renogy Rover 60A controller has a max PV input voltage of 140VDC. This would currently power a small 120v dorm fridge (via a Renogy 2000W 12V inverter) but I have future plans for a couple of RV pumps for water, too.

I'm not familiar with bifacial panels and whether they have a single set of PV output wires (front and back combined) or if they have two sets (one for front, one for back). I have a distance of about 60' from my panels to the charge controller, so I'm looking to maximize voltage and minimize wire size.

Given the Voc is almost 50VDC, I would like to wire two of them up in series (for 100VDC Voc) but I don't think I could wire all three of them up in series because it would be 150VDC total and that's 10VDC over the Renogy Rover's stated limit.

Any advice for a not-quite-newbie but also not-an-expert?

Thanks in advance.

To add: One thing I'm curious about is whether the Max PV Input Voltage for charge controllers is usually a very strict rule or one that has some slight wiggle room (aka: around +10 VDC if I wire all three panels up in series to maximize input voltage). Thanks!
