# 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).
#
# !!! 2026-06-24 FINDING — grid-assist lever corrected, still UNVALIDATED !!!
# The original idea (stop_charge_voltage: 0 = "Full") was REJECTED by the firmware:
# `flash.py apply` got an inverter NAK on `BUCD480,000` on BOTH units (no change made).
# The field flash.py calls `stop_charge_voltage` is really the inverter's
# **battery_re_discharge_voltage** (HA: sensor.lvx6048_*_battery_re_discharge_voltage) —
# the voltage at which the inverter switches loads back to battery after grid charging.
# At 54.0 V, grid tops the bank only to ~54 V. Raising it (below) lets grid charge
# higher, BUT it may band-oscillate near the setpoint rather than hold a clean
# absorption, so it's NOT guaranteed to give the full-charge termination the BMS needs
# to re-anchor. SOLAR-ONLY is the known-good method (solar follows the full CC/CV curve
# to bulk + absorption); use this grid profile only as a supervised experiment.
#
# Corrected (candidate) change vs canonical: stop_charge_voltage 54.0 -> 56.0 (was 0).
# bulk_voltage stays 56.4 (absorption target).
#
# 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.
