Pros & Cons
EcoFlow DELTA Pro 3
Pros
- +240V output through an L14-30R means it can genuinely back-feed a house transfer switch, which almost nothing else here can
- +Expandable to 48kWh as a full system — this is whole-home territory
- +2,600W of solar input across dual MPPT
- +Its price has fallen roughly $900 from launch
Cons
- −113.5lb — it has wheels for a reason, and it is not going camping
- −The 6,000W X-Boost figure is voltage reduction, not true surge
- −Only two USB-C and two USB-A ports on a station this size
- −Full system expansion runs into five figures quickly
