Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the EcoFlow RIVER 2?

Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the EcoFlow RIVER 2: about 23.5 V on a 20°F morning against the station's 30 V limit, and about 110 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 110 W.

Verdict

Works

1 x NextGen 220W Bifacial Portable Solar Panel into the RIVER 2 (1 panel on Solar input) stays inside 11 to 30 V, even at 20F. The station caps the current at 8 A.

Quick answers

Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the EcoFlow RIVER 2?

Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the EcoFlow RIVER 2: about 23.5 V on a 20°F morning against the station's 30 V limit, and about 110 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 110 W.

Can I connect two NextGen 220W Bifacial Portable Solar Panel panels to the RIVER 2?

Yes, 2 panels in parallel on Solar input. That gives about 110 W.

What cable do I need to connect the NextGen 220W Bifacial Portable Solar Panel to the RIVER 2?

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 RIVER 2 accepts up to 30 V on the Solar input.

Rules we applied
  • EcoFlow RIVER 2: solar input 11 to 30 V on the Solar in (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 8 A cap is safe: the station takes 8 A and you get fewer watts. We count only the capped watts.
  • Max 110 W on this input.
Assumptions
  • 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.
