Key Features
4,096Wh High-Capacity Battery
DELTA Pro 3 provides 4,096Wh of built-in energy storage using durable LFP battery chemistry, making it suitable for extended backup power and off-grid applications.
4,000W Continuous Output
The system provides up to:
- 4,000W maximum continuous output
- 8,000W maximum surge output for 400ms
- 6,000W X-Boost output
- Approximately 8kW optional extended range when using two DELTA Pro 3 units with a 50A Hub
120V/240V Split-Phase Support
DELTA Pro 3 supports 120V/240V output and can power high-demand equipment through its 240V connections.

It connects to the home’s main electrical panel and can automatically transfer selected backup loads to available backup power when the grid goes down.
The panel consists of:
- Distribution panel
- Battery connection box
- Relay-controlled switches
- Backup-load breakers
The system can manage multiple power sources, including:
- Utility/grid power
- DELTA Pro 3 battery systems
- Solar power
- Generator power
Smart Home Panel 2 Capacity
A Smart Home Panel 2 installation can connect up to 3 DELTA Pro 3 power stations.
Each DELTA Pro 3 can support up to 2 extra batteries.
EcoFlow strongly recommends that Smart Home Panel 2 installations be completed by a professional EcoFlow-certified electrician.
App Control & Connectivity
DELTA Pro 3 supports:
- Wi-Fi 2.4GHz
