It enables effortless whole-home power backup and ensures continuous power supply, even during system installation or rare inverter failures, delivering a smooth and reliable user experience.
Whole-Home Power Backup
EcoFlow PowerBox makes whole-home power backup easier than ever. It supports a dedicated whole-home backup wiring method for EcoFlow PowerOcean (Three-Phase) to keep your household powered during outages.
Uninterrupted Power Supply
Compatible with both EcoFlow PowerOcean (Three-Phase) and PowerOcean Plus (Three-Phase), PowerBox ensures uninterrupted power during system installation or rare inverter failures by simply switching manually to draw power directly from the grid.
Operating Conditions with EcoFlow PowerOcean (Three-Phase)
On-Grid Operating Condition
Under on-grid operating condition, the backup load will be powered by the grid and the inverter.
Off-Grid Operating Condition
Under off-grid operating condition, flip it upwards [upward-arrow] to enable the Backup output. The backup load will be powered by the inverter.
Operating Conditions with EcoFlow PowerOcean Plus (Three-Phase)
Normal Operating Condition
Under normal operating condition, flip it upwards [upward-arrow] to enable the Backup output. The backup load will be powered by the inverter and the grid (grid-connected only).
Fault Condition
In case of an inverter failure, the inverter can be bypassed manually, allowing the backup load to be directly powered by the grid. Please follow the instructions below: 1. Turn off AC breaker. 2. Flip it downwards [downward-arrow] to enable the Grid output.
