+# 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

+# 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)
