Multi-input monitoring, LED indications and the distinction between a warning and an operating limit.
The technical question
The research approach
The research examined archived manufacturer manuals alongside patents and original-language documents. It separated a multi-LED reading from a ground combining the monitored architecture with single-indicator disclosures.
See the strongest passages and the unresolved element in the same record.

The manual describes continued grid feeding with a current, output or temperature limitation. Its separate red-flashing state states a warning, but does not say whether feeding continues.

LED green, flashing Solar Inverter is active and feeds into power grid, however with current, output or temperature limitation.

What the score reflects
This mapping depends on treating the operating limitation as a warning, the manual’s date evidence, and the reason to combine references. That uncertainty remains visible.

Recorded assessment: 15 October 2026. Scores assess the evidence for this ground; they are not probabilities of invalidity. P2 is the reason to combine, a claim-wide point.
The SMA manual expressly describes operating modes displayed through LEDs on the inverter housing.
The recorded strength is A 97 for this element in both grounds. Coverage of this element does not resolve the separate single-LED question.
SMA BEN082220 · §4 · Printed p. 16
The manual describes separate inputs with individual MPP trackers, per-input faults and per-string measurements.
The complete mapping uses several passages. The research record separately addresses the meaning of “input channel”.

SMA expressly connects the device’s operating mode with the integrated LEDs.
This passage supports actuation of the indicators. Whether the claimed states appear on one system-status LED is assessed separately.
SMA BEN082220 · §4 · Printed p. 16
Sunways describes one combined red/green LED, continuously green during grid feeding. The chart combines that indication with SMA’s monitored-input architecture.
B 75 is the recorded strength of the combination, including its reason to combine. This source passage is one part of that ground.

The manual describes continued grid feeding with a current, output or temperature limitation. Its separate red-flashing state states a warning, but does not say whether feeding continues.
This mapping depends on treating the operating limitation as a warning, the manual’s date evidence, and the reason to combine references. That uncertainty remains visible.
Sunways AT manual · §5.1 · Printed p. 27
The Sunways combined LED shows a continuously red error state. The chart also cites Fronius, Soladin and a Japanese reference for error indications.
The score includes the reason to combine these indications with SMA’s architecture. A single isolated passage is not the complete ground.
Sunways AT manual · §5.1 · Printed p. 27
The Sunways display distinguishes an AC-network error. The chart relies on Soladin and the Japanese 366 publication for a grid-specific code on one LED.
The highlighted Sunways text describes a display code, not a distinct grid-error LED state. The other references supply that part of the combination.
Sunways AT manual · §5.5 · Printed p. 38
Sunways identifies the unlit state as inactive night mode. The chart cites corresponding states in the Soladin and Fronius documents.
The recorded B 75 reflects the combined ground and its reason to combine, rather than this sentence alone.
Sunways AT manual · §5.1 · Printed p. 27
The recorded rationale addresses putting SMA’s monitored operating states onto a single two-colour indicator. It is a claim-wide point, not an additional limitation.
The assessment records a three-reference combination. This point affects the 16c1–16c5 ratings and must be read with the complete rationale.
