Wheeled LFP base with real 6,000 W continuous and 120/240 V in one box. 3,840 Wh is a half-day essentials tank until you add BP3800 packs. Home Power Panel is optional — not in this SKU.

Mixing BP2000/BP2600 — F3800 expects BP3800
What it is
US F3800 (A1790 family): 3,840 Wh LFP, 6,000 W / 9,000 W surge, ~132 lb. Up to six BP3800 → ~26.9 kWh. Not F2000, not F3800 Plus.
How we estimate runtime: At a 500 W load: 3,840 × 0.85 ÷ 500 ≈ 6.5 h. Usable Wh = rated × 0.85 (Outage Stack planning assumption, not manufacturer).
Verdict
Buy as a dual-V expandable station base. Treat Wh and the optional panel honestly — watts do not create watt-hours.
