The DELTA Pro Ultra is ideal for large homes or users who want full control over energy backup. It’s powerful, smart, and expandable. Though expensive, it replaces gas generators completely with clean, quiet energy.
Detailed Comparison: Anker SOLIX F3800 vs EcoFlow DELTA Pro Ultra
The Anker SOLIX F3800 and EcoFlow DELTA Pro Ultra both aim to deliver full-house backup in a portable design, yet they cater to different scales.
The SOLIX F3800 starts smaller, with 3.84kWh capacity and 6000W power, ideal for short outages or RV trips. It’s expandable up to 26.9kWh, which is enough for a few days of energy.
The DELTA Pro Ultra, on the other hand, begins at 6kWh but scales to an incredible 90kWh, making it suitable for full-home power during long blackouts.
Its 7200W AC output handles heavier loads than the Anker’s 6000W. Both use LiFePO4 batteries, ensuring safety and a long lifespan.
The EcoFlow wins in recharge time — only 2 hours compared to the Anker’s longer cycle. The Anker, though, offers better portability and easier use for RVs or mobile setups.
For everyday backup and mobility, the Anker SOLIX F3800 is the more practical choice. For large homes or full off-grid living, the EcoFlow DELTA Pro Ultra delivers unmatched performance.
