# LVX6048 settings profile — EG4 LifePower4 v2 LiFePO4 bank, open-loop.
|
||
#
|
||
# Designed for: 3× EG4 LP4 v2 100 Ah in parallel (300 Ah, ~15.4 kWh).
|
||
# Apply identically to both inverters in a parallel pair:
|
||
# sudo systemctl stop powermon.service powermon2.service
|
||
# ./flash.py apply --device /dev/lvx6048-1 --profile profiles/eg4-lp4-v2.yaml --confirm
|
||
# ./flash.py apply --device /dev/lvx6048-2 --profile profiles/eg4-lp4-v2.yaml --confirm
|
||
# sudo systemctl start powermon.service powermon2.service
|
||
# ./flash.py compare --device-a /dev/lvx6048-1 --device-b /dev/lvx6048-2

# Voltage rationale (16S LFP, 3.2 V/cell nominal = 51.2 V pack):
|
||
# bulk 56.4 V = 3.525 V/cell — long-life sweet spot for LFP
|
||
# float 54.0 V = 3.375 V/cell — rest near mid-knee, avoid sitting on the top
|
||
# stop_charge 54.0 V — grid charges only to ~mid-knee; solar handles the bulk top-off
|
||
# stop_dis 48.0 V = 3.000 V/cell — soft "switch to grid" point
|
||
# cutoff 48.0 V = 3.000 V/cell — inverter hard shutdown floor (BMS still protects below)
|
||
# Conservative off-grid policy: keep grid as a soft top-up, let solar do the bulk work.
|
||
#
|
||
# Current rationale (300 Ah bank):
|
||
# 60 A/unit × 2 units = 120 A combined ≈ 0.4 C — well under bank's continuous spec
|
||
# 30 A/unit MUCHGC keeps grid-charging conservative (60 A combined)
