450/100 vs 250/100 - bad Performance

Hi everybody!

I have one Array (At the moment) containing 8 panels with total 320 Voc.

First I had the 250/100 installed with 2x4 panels and the yeild was good.
Now after switching to the 450/100 rs and the change to one string in series I have the feeling that I am missing 15 to 20 % of my yields. Of course winter is aproaching but over the last year I got quite a good feel for my 250/100 chargecontrollers, and something is off. Its always 1 or 2 kwh less than it used to be with the 250/100.

Why is the performance of the 450/100 rs worse?
Already did an update and .. well nothing changed.

Sincerrely
Adam J.

Individual trackers are limited to 4000W (18A PV side)

Spread the panels across both.

All documented in the spec sheet.

Thank you very much but 4000w were never reached in this confiuguration, even with the 250/100 because of the orientation (flat, no shadows)


So this was not the limiting factor.
