Will the EcoFlow 100W Flexible Solar Panel work with the EcoFlow RIVER 2?
Yes. One EcoFlow 100W Flexible Solar Panel works with the EcoFlow RIVER 2: about 22.4 V on a 20°F morning against the station's 30 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 110 W.
Works
1 x 100W Flexible Solar Panel into the RIVER 2 (1 panel on Solar input) stays inside 11 to 30 V and under 8 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 |
|---|---|---|---|---|---|
| 2 panels in parallel on Solar input The panels can push 11.8A but this input takes 8A, so the station caps it. Safe, you just lose some watts. | Solar input | 22.4 | 11.8 | 110 | Works |
| 2 panels in series on Solar input Open-circuit voltage 40.6V is above the station's 30V limit. Going over a station's input voltage limit can damage it. | Solar input | 44.8 | 5.9 | 0 | Don't connect |
Quick answers
Will the EcoFlow 100W Flexible Solar Panel work with the EcoFlow RIVER 2?
Yes. One EcoFlow 100W Flexible Solar Panel works with the EcoFlow RIVER 2: about 22.4 V on a 20°F morning against the station's 30 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 110 W.
Can I connect two 100W 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 100W 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 100W Flexible Solar Panel goes from 20.3 V on its label to about 22.4 V at 20°F and 23.2 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 0.33% per °C below 77F (25°C), this panel's own figure. At 20F one panel's 20.3 V becomes 22.4 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 this panel's own coefficient from its manual, 0.33% per °C.
- Expected watts are the best case in full sun. Real-world midday output is usually 60 to 80% of that.
