More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

Hi BFL13,
The line loss in the MPPT example is voltage. 2% is a good number. Does that change your wattage figures?
MPPT does not just buck. However, as Salvo used to point out MPPT controllers do switch over to PWM at some point--depending on their design.
PT, No. According to my calculator--YMMV--:) it comes out the same.
The MPPT does stop tracking once Bulk is done, but even in absorb or float doing "PWM" it is still a buck converter at say 24/12 so it is not the same action internally as a "PWM" doing 12/12.
Almot, I am happy for you that your solar controller can do your thinking for you, while you zone out. :)_ It watches the weatherman on TV and makes plans, and even looks out the window to see it getting more cloudy than forecast and adjusts itself. Pretty neat!
