Will the EcoFlow 100W Rigid Solar Panel work with the EcoFlow RIVER Max Plus?
Yes. One EcoFlow 100W Rigid Solar Panel works with the EcoFlow RIVER Max Plus: about 22.4 V on a 20°F morning against the station's 25 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 200 W.
Works
1 x 100W Rigid Solar Panel into the RIVER Max Plus (1 panel on Solar input) stays inside 10 to 25 V and under 12 A, even at 20F.
- Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the EcoFlow 100W Rigid Solar Panel work with the EcoFlow RIVER Max Plus?
Yes. One EcoFlow 100W Rigid Solar Panel works with the EcoFlow RIVER Max Plus: about 22.4 V on a 20°F morning against the station's 25 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 200 W.
Can I connect two 100W Rigid Solar Panel panels to the RIVER Max Plus?
Yes, 2 panels in parallel on Solar input. That gives about 200 W.
What cable do I need to connect the 100W Rigid Solar Panel to the RIVER Max Plus?
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 Rigid 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 Max Plus accepts up to 25 V on the Solar input.

Other panels that work with the RIVER Max Plus
- EcoFlow RIVER Max Plus: solar input 10 to 25 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 12 A cap is safe: the station takes 12 A and you get fewer watts. We count only the capped watts.
- Max 200 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.
