Lowest OCV An MPPT Is "Worth It"?
There has to be some experience here on this forum to share. When I look at the MPPT manufacturer's data specs, the incredo-hyperbole gives me diarrhea.

I did comparison tests between my Xantrex PWM and my blue sky 2000e solar boost mppt , the 2000e mppt won out
If you are looking at high voltage panels, you have no choice, use mppt or waste a lot of watts
If your looking at panels 17.5 to 19v , it's going to depend on the particular controllers being compared
My Xantrex basically goes four hours at bulk then shifts to 13.2 volts , no good to me because my batteries are not recharged in only for hours of solar
And it does not restart/reset unless it's night or I disconnect the batteries aka manual reset, but this is a quirk in the Xantrex programming and might not be in the charge profile/program of the PWM you are looking at
