60 Cell Panel vs 24v Bank MPPT and PWM UPDATE
UPDATE--results with MPPT posted 1 June. Got a chance to run this test today with no clouds but a slight haze up high so not quite 1000 insolation, showed as 8.93Isc vs rated 9.0, however that did ...

Jim, thanks for the tests you already did, showing the Eco-W gets as many amps out as the fancy controller. The fancy features are what is being paid extra for, not for more amps.
The controllers were at ambient 20C in a light breeze off the sea, so no overheating issues. The panel and controllers are performing to spec.
It does look like there is still a small penalty in the MPPT buck conversion, which the PWM doesn't have but it is tiny. So 24-24 if you already have a 12/24 controller, either type will do the job.
