Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow RIVER 2?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow RIVER 2: about 27.9 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.
Works
1 x 175W Rigid Solar Panel into the RIVER 2 (1 panel on Solar input) stays inside 11 to 30 V and under 8 A, even at 20F.
- EcoFlow's spec table labels the 7.85 A figure as a voltage; it is the operating current.
- Use the solar charging cable that came with the station (MC4 on the panel side).

| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 2 panels in parallel on Solar input The panels can push 15.7A but this input takes 8A, so the station caps it. Safe, you just lose some watts. | Solar input | 27.9 | 15.7 | 110 | Works |
| 2 panels in series on Solar input Open-circuit voltage 51V is above the station's 30V limit. Going over a station's input voltage limit can damage it. | Solar input | 55.8 | 7.9 | 0 | Don't connect |
Quick answers
Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow RIVER 2?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow RIVER 2: about 27.9 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 175W Rigid 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 175W Rigid 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 175W Rigid Solar Panel goes from 25.5 V on its label to about 27.9 V at 20°F and 28.8 V at 0°F. The RIVER 2 accepts up to 30 V on the Solar input.

Other panels that work with the RIVER 2
- 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 25.5 V becomes 27.9 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.
- 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.
