Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

If voltage is lower than Vmp you get less power but go up in Isc on the IV curve, so to get lower power but also lower amps, you have to raise the panel voltage?
Yes.

In Float I will see 2 amps or so going into the batteries. This equates to less than 1 amp on the panel side. If you look at a typical IV curve the only place you will find 1 amp output is near Voc. I have verified this as panel voltage is 41 to 42 volts in float with little to no loads.

That's pretty clearcut.
Perhaps the advantage of using the high V, low I side of the power curve to reduce power would be lower line losses from the panels to the controller?
