✓ What We Liked
- 3,840Wh built-in, expandable to 26.9kWh for true whole-home backup
- 6,000W output with 120V/240V split-phase runs the heaviest household loads
- One of the most powerful single-unit stations for off-grid cabins
- Direct upgrade path over the base Anker SOLIX F3800 for higher output and capacity
- Competes head-on with the EcoFlow DELTA Pro 3 in the split-phase, 4000W+ class
✗ What We Didn't
- $4,799 is a premium price before any expansion batteries
- Heavy, effectively stationary hardware even with wheels
- 240V split-phase benefits need proper transfer-switch installation
- Recent release — limited independent long-term testing at launch
