Choosing between the EcoFlow Delta Pro 3 and Anker Solix F3800 can be tough—they’re both powerful, expandable solar generators built for home backup and off-grid use. This guide compares the specs, features, and key differences between these two high-capacity units to help you decide which one is better suited for your energy needs.
Based on technical specifications and user-reported performance, here’s how they stack up.
Specs Comparison Table

|---|---|---|
| Battery Capacity | 4096Wh | 3840Wh |
| Inverter Power | 4000W (8000W surge) | 6000W (9000W surge) |
| Battery Chemistry | LiFePO4 | LiFePO4 |
| Expandable Capacity | Up to 12kWh | Up to 26.9kWh |
| 240V Split-Phase | Yes (2 units required) | Yes (native support) |
| EV Charging Support | Yes (Level 2 / NACS support) | Yes (Tesla & J1772 ready) |
| Solar Input (Max) | 2600W (1600W + 1000W) | 2400W |
| Weight | 115 lbs | 132 lbs |
| WiFi / App Control | Yes | Yes |

Power & Performance
The Anker Solix F3800 delivers higher continuous power at 6000W, compared to the 4000W output of the Delta Pro 3. This makes the Anker better for running multiple high-draw appliances simultaneously, especially in home backup scenarios.
However, both units handle surge loads well, and the Delta Pro 3’s 8000W peak is still strong for most use cases.
Battery Capacity & Cycle Life
The EcoFlow Delta Pro 3 has a slightly higher base capacity at 4096Wh, while the F3800 offers 3840Wh. Both use LiFePO4 batteries, known for long cycle life—typically 3,500+ cycles to 80% capacity.
Where Anker pulls ahead is in expandability. With additional batteries, it can scale up to 26.9kWh, compared to 12kWh with EcoFlow’s ecosystem.
Output Ports & Expandability
Both units include a wide array of AC outlets, DC ports, and EV charging compatibility. The Anker Solix F3800 includes native 240V split-phase support, meaning you don’t need a second unit to power 240V appliances.
The Delta Pro 3 requires pairing with a second unit and EcoFlow’s Smart Home Panel 2 for full 240V integration.
Both models integrate with home circuits and support EV charging via NACS (Tesla) and J1772.
Portability & Weight
Neither model is light, but the Delta Pro 3 is slightly more manageable at 115 lbs, compared to 132 lbs for the Anker F3800. Both include wheels and telescoping handles to aid portability, but you’re not lifting either without help.
Charging Options
The Anker Solix F3800 still leads in single-port solar input at 2400W, but the Delta Pro 3 now offers a combined solar input of 2600W using two MPPT ports:
- High-PV Port: 30–150V⎓, 15A, up to 1600W
- Low-PV Port: 11–60V⎓, 20A, up to 1000W
This dual-input setup makes the Delta Pro 3 more flexible for users with mixed solar panel types or for optimizing performance in partial-shade conditions.
Both units also support:
- AC charging
- EV station charging
- Dual AC + solar inputs for faster top-ups
- Generator input
Price & Value
At around $3,699, the EcoFlow Delta Pro 3 offers a slightly lower entry price, especially for users who don’t need max output or 240V split-phase right away.
The Anker Solix F3800 costs about $3,999, but delivers higher output power, better expandability, and native 240V support—offering strong value for home backup users who want a more scalable solution.
Final Verdict
Choose the EcoFlow Delta Pro 3 if:
- You want a reliable solar generator under $4,000
- You’re already in the EcoFlow ecosystem (e.g., Smart Home Panel 2, extra batteries)
- You prefer a slightly lighter unit with app control and smart features
Choose the Anker Solix F3800 if:
- You need 6000W power output and native 240V support
- You plan to expand capacity significantly (up to 26.9kWh)
- Faster solar charging is a top priority
For most home backup users, the Anker Solix F3800 offers more long-term flexibility and power, while the EcoFlow Delta Pro 3 is a better fit for those seeking a balanced, smart system at a slightly lower cost.
