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...

I think most guys that have familiarity with electronics will choose fanless with big heat sinks over a more compact chassis with a fan. The reason that there is heat to dissipate is the use of larger current carrying devices like MOSFET's, IC's, and transistor regulators. All of those will heat up when passing current and need a heatsink interface. It's sometimes more elegant to use a larger heatsink than using smaller ones and a fan.
