high-voltage mppt controllers?
I'd like to mount two 260-290 watt panels on my TT, rather than several smaller more expensive 100-150w panels. What controllers are popular these days, for high cell count panels (60 to 72 cells p...

Hi Gordon,
If you keep the wattage down to 500 the Rogue 3048 is quite an amazing piece of technology. It might be, that with a fixed install, a pair of 260 watt panels would rarely get over that number. It features a battery temperature probe, battery voltage sense wires, and (I think) does diversion loads as well.
Over 500 watts, and under 800, I'd go with the Tristar 60 amp MPPT unit. This is actually three 20 amp controllers piggy backed together. As solar harvest rises, first one section runs, then another is added. This allows it to run more efficiently, wasting less on overhead. The only lack on the MPPT unit is no diversion load.
Both of these units easily connect to a laptop so that their parameters can be tweaked, for items such as voltage set points.
