noise 4d6c6c109b Correct PV analysis: no down string; peak is charge-cap-limited ...

Clear-noon peak (2026-06-24 13:44, HA recorder): each inverter ~4.7kW @ ~300V
@ ~16A. A down string reads ~10A; ~16A = both parallel strings live. The
"one string down per inverter" belief was from confounded afternoon/rainy
samples + transient pv_loss_warning (now off) and is refuted.

~66% of nameplate at peak is explained by 45-deg tilt (wrong for high June sun),
heat derate, and tree shading. AND the peak was demand-limited: battery charge
pinned at the 120A cap (121A) at 65% SoC with only 3.3kW load -- reversing the
earlier off-peak "not clipping" note. Documented the throttle test to resolve
true array ceiling before raising max_charging_current.
