Following your spring discussion. Did you use Lee springs LHL 625d 03 as in your posting. Or different springs as on your material list?

Question about a pool pump - JP21-19/900 - 72VDC, 900w, 1.2HP, 62ft, 92GPM, Solar MPPT Controller -
I have 4 x 270watt @ 35.5v Solar Panels.
Will the controller handle 142 volts coming in and deliver the required 92v and 900w if connected in series?
Or will I have to connect 3 panels in series and 1 panel in parallel to them?
Or possibly 2 pairs of panels in series and then connected in parallel?
