Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the EcoFlow DELTA 2 Max?
Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the EcoFlow DELTA 2 Max: about 23.5 V on a 20°F morning against the station's 60 V limit, and about 219 W in full sun. Two panels: works (1 panel on Solar input + 1 panel on Solar input), about 438 W.
Works
1 x NextGen 220W Bifacial Portable Solar Panel into the DELTA 2 Max (1 panel on Solar input) stays inside 11 to 60 V and under 15 A, even at 20F.
- Use the solar charging cable that came with the station (MC4 on the panel side).

| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 1 panel on Solar input + 1 panel on Solar input Best option | Solar input + Solar input | 23.5 | 11.9 | 438 | Works |
| 2 panels in series on Solar input | Solar input | 47.1 | 11.9 | 438 | Works |
| 2 panels in parallel on Solar input The panels can push 23.8A but this input takes 15A, so the station caps it. Safe, you just lose some watts. | Solar input | 23.5 | 23.8 | 276 | Works |
Quick answers
Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the EcoFlow DELTA 2 Max?
Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the EcoFlow DELTA 2 Max: about 23.5 V on a 20°F morning against the station's 60 V limit, and about 219 W in full sun. Two panels: works (1 panel on Solar input + 1 panel on Solar input), about 438 W.
Can I connect two NextGen 220W Bifacial Portable Solar Panel panels to the DELTA 2 Max?
Yes, 1 panel on Solar input + 1 panel on Solar input. That gives about 438 W.
What cable do I need to connect the NextGen 220W Bifacial Portable Solar Panel to the DELTA 2 Max?
Use the solar charging cable that came with the station (MC4 on the panel side).
Is it safe on a cold morning?
Panel voltage rises in the cold. One NextGen 220W Bifacial Portable Solar Panel goes from 21.5 V on its label to about 23.5 V at 20°F and 24.3 V at 0°F. The DELTA 2 Max accepts up to 60 V on the Solar input.

Other panels that work with the DELTA 2 Max
- EcoFlow DELTA 2 Max: solar input 11 to 60 V on the Solar in 1 (Solar input). EcoFlow sets this limit on open-circuit voltage (Voc), so we hold the panels' Voc on your coldest morning to it.
- Cold raises panel voltage: we add 0.30% per °C below 77F (25°C), a typical figure, since this panel does not publish its own. At 20F one panel's 21.5 V becomes 23.5 V.
- Current over the 15 A cap is safe: the station takes 15 A and you get fewer watts. We count only the capped watts.
- Max 500 W on this input, 1,000 W across all inputs.
- Cold-morning voltage uses 0.30% per °C, typical for crystalline panels. This panel's own value is not published.
- Expected watts are the best case in full sun. Real-world midday output is usually 60 to 80% of that.
