Well somebody please nip out there and measure panel voltage during Absorb/Float while running a load that puts amps above array total Isc.
It is easy to do. Just put the meter across the pos and neg controller input terminals or do it out at the panel. Nothing disconnected of course.
My Vmp is 30v so when I check for that when MPPT is on I get 29.3 at panel and 29 at controller. So I have a 1% line loss there. YMMV. Trouble is I never took the voltage later on after it dropped out of MPPT. Can't check again till after mid-April.
So somebody here must be on MPPT solar now that can help out! :)
