Unattended morning runner for the calibration top-off. DEFAULT is solar-only
@ 60A: no setter, reads telemetry, weather-gates (PV<4kW by 10:30 -> abort),
monitors the charge with cell>3.65V / temp>45C aborts, verifies all 6 packs
re-anchor to 100%. Validated end-to-end via --dry-run against live HA.
Key firmware finding baked in (confirmed live): MCHGC is LOCKED while charging
(NAKs even in device_mode 'Battery' when charger_status='charging') -- so the
80A throttle test is opt-in (THROTTLE=1), gated on a true pre-charge idle
window, with retry-on-revert and a guaranteed-safe fallback (cap stays 80A
until idle if revert NAKs). No clean noon A/B is possible; documented as such.
Also handles the HA pack-temperature unit trap (entities report degF; the
script reads unit_of_measurement and converts to degC for the safety check).
REFERENCE: documented the MCHGC charging-lock under known issues.
