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.

# LVX6048 settings profile — TEMPORARY calibration charge for the EG4 LP4 v2 bank.
|
|
#
|
|
# Purpose: re-anchor drifted EG4 pack SoC counters (and top-balance) by letting the
|
|
# bank reach a FULL charge with absorption hold. The EG4 BMS resets SoC to 100% only
|
|
# on a real full-charge termination (high cell voltage + low taper current); the
|
|
# conservative everyday profile stops grid charging at 54.0 V (mid-knee), so on cloudy
|
|
# / high-load stretches the bank may go weeks without a full charge and the coulomb
|
|
# counters drift (e.g. pack 6 read 76% while physically at ~53% on 2026-06-24).
|
|
#
|
|
# The ONLY change vs the canonical eg4-lp4-v2.yaml is:
|
|
# stop_charge_voltage: 54.0 -> 0 (= "Full"; remove the grid-charge ceiling so a
|
|
# full charge can complete even without strong sun)
|
|
# bulk_voltage stays 56.4 (the absorption target). Solar already charges past 54 V on a
|
|
# good day; this profile just lets GRID finish the top-off when solar can't.
|
|
#
|
|
# USE: this is a TEMPORARY profile driven by the `calibration-charge` skill. Apply to
|
|
# BOTH inverters, run the full charge, verify all 6 packs hit 100%, then REVERT to
|
|
# eg4-lp4-v2.yaml. Do not leave this profile applied — it removes the everyday
|
|
# grid-charge ceiling.
