The everyday profile caps grid charging at 54V, so the bank can go weeks
without a full charge and the EG4 BMS coulomb counters drift (proven: pack 6
read 76% SoC while at the same 53.4V/3.337V-per-cell as packs reading 50-55%
— all paralleled, so physically equal charge; the spread is pure drift).
- profiles/eg4-lp4-v2-calibration.yaml: temporary profile, identical to
canonical except stop_charge_voltage 54.0 -> 0 (Full), so grid can finish a
full charge to the 56.4V absorption hold that re-anchors every pack to 100%.
- calibration-charge skill: guided runbook (pre-flight safety, two methods
solar-only / grid-assist, live monitoring with cell-voltage/temp aborts,
re-anchor verification, mandatory revert).
- REFERENCE: scoped action-policy exception (this skill alone may flip
stop_charge, both units, user-confirmed, must revert); corrected pack-6 /
SoC-drift notes to the verified equal-voltage-different-SoC signature.

Four Skill-tool skills under .claude/skills/ that let an agent monitor and
troubleshoot the install (2x LVX6048, 6x EG4 LifePower4, OpenEVSE), grounded
in the real MQTT/HA topology rather than generic advice:
- solar-health-check : whole-system sweep + cross-checks + R/Y/G verdict,
incl. cross-unit "silently-dead inverter" detection
- troubleshoot-inverter: FWS fault decode, parallel sync, USB link recovery
- troubleshoot-battery : per-pack imbalance vs SoC-counter-drift, RS485 silence
- power-usage : PV/load/grid/battery balance + EVSE sessions
Shared lib:
- solar-snapshot : live MQTT capture (creds from powermon.yaml, no hardcoding)
- ha-history : HA recorder lookback (token from ~/.config/ha/token)
REFERENCE.md documents topology, real HA entity_ids (doubled slug), known
issues, and a safe-remediation-only action policy (restarts yes; setters no).
Action boundary: diagnose + restart wedged daemons / recover USB links;
never touches inverter/battery setters or flash.
