Will the Renogy 200W Flexible Solar Panel work with the EcoFlow RIVER 2?

Yes. One Renogy 200W Flexible Solar Panel works with the EcoFlow RIVER 2: about 26.2 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 200W Flexible 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.

  • The panels can push 10A but this input takes 8A, so the station caps it. Safe, you just lose some watts.
Cables to buy
  • Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers

Will the Renogy 200W Flexible Solar Panel work with the EcoFlow RIVER 2?

Yes. One Renogy 200W Flexible Solar Panel works with the EcoFlow RIVER 2: about 26.2 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 200W Flexible 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 200W Flexible 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 200W Flexible Solar Panel goes from 23.9 V on its label to about 26.2 V at 20°F and 27 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 23.9 V becomes 26.2 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.
