EcoFlow DELTA Pro 3 accessories
The solar panels and add-on batteries that EcoFlow itself sells for the DELTA Pro 3. We list an accessory only where the maker states the pairing, and show that statement, its source and the date we last confirmed it.
Solar panels
| Panel | Price | One panel refills it in (est.) | Why it's listed | |
|---|---|---|---|---|
| EcoFlow NextGen 220W Bifacial Portable Solar Panel 220W | $399 2026-10-11 | 25 sun-hours | EcoFlow sells the DELTA Pro 3 with it as a kit: “DELTA Pro 3 + 2 × 220W Solar Panels” (source, confirmed 2026-10-11) | |
| EcoFlow 400W Portable Solar Panel 400W | $599 2026-10-11 | 14 sun-hours | EcoFlow sells the DELTA Pro 3 with it as a kit: “DELTA Pro 3 + 400W Solar Panel” (source, confirmed 2026-10-11) |
Refill time is our estimate, not a test: 4,096Wh ÷ (panel watts × 75% real-world output). A "sun-hour" is an hour of strong, direct sun; most of the US gets 3–5 a day, fewer in winter. The DELTA Pro 3 accepts up to 2,600W of solar in total (EcoFlow's figure), so more panels charge it faster up to that limit; check the manual for how to connect more than one. Prices are EcoFlow's store prices on the date shown.
Add-on batteries
| Battery | Price | Capacity with one added | Fridge runtime with it (est.) | Why it's listed | |
|---|---|---|---|---|---|
| EcoFlow DELTA Pro 3 Smart Extra Battery 4,096Wh | $1,899 2026-10-11 | 8,192 Wh from 4,096 | 5.5 days from 2.8 days | EcoFlow sells the DELTA Pro 3 with it as a kit: “DELTA Pro 3 + Extra Battery” (source, confirmed 2026-10-11) |
Capacities are EcoFlow's published figures. Fridge runtime is our estimate (full-size fridge, 85% inverter efficiency), not a test. EcoFlow says the DELTA Pro 3 can be expanded to 48,000Wh in total.
