Do you have 5 60-cell or 5 72-cell modules in series? 

I recall that active tracking has to have 230V to start and then can go down to 195V. I’m reading from an old manual, though. 

The new manual is here:

I am old enough to be quite aware of “VAPOR WARE” and old enough to know that there may be someone that has reset this setting and actually had it function. Manufacture alledges it “should work”………..NO white paper or any additional info from SE Solar either. Anyone?
