- Simple manual grid/backup transfer — ideal for installation and rare service scenarios
- Compatible with EcoFlow PowerOcean (3-phase) and PowerOcean Plus (3-phase)
- Rugged indoor enclosure: IP40, IK10, passive cooling by natural convection
- High electrical capacity: 63 A max, 50 A continuous; 400 V AC, 50/60 Hz
- Quick wall-mount installation, compact footprint (302 × 373 × 132 mm), 5.0 kg
Overview
The EcoFlow PowerBox EF-SD-002 is a three-phase manual transfer switch for PowerOcean systems. It reliably separates and switches between grid and backup so loads keep running during outages. With a 400 V AC rating, up to 63 A max current and CE compliance, it is engineered for efficiency, safety and long-term reliability.
Functions & Installation
The PowerBox is designed for fixed integration with EcoFlow PowerOcean (3-phase), enabling whole-home supply via the inverter during grid failures. The manual switch offers positions I–0–II, allowing transfer between the grid input and the inverter’s backup terminal depending on the system layout. With PowerOcean Plus (3-phase), it supports normal operation and a service mode using the inverter’s integrated bypass — helpful for rare failures or maintenance.
