Will the Rich Solar MEGA 100 FLEX work with the EcoFlow RIVER Max Plus?
Yes. One Rich Solar MEGA 100 FLEX works with the EcoFlow RIVER Max Plus: about 22.3 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 MEGA 100 FLEX 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 Rich Solar MEGA 100 FLEX work with the EcoFlow RIVER Max Plus?
Yes. One Rich Solar MEGA 100 FLEX works with the EcoFlow RIVER Max Plus: about 22.3 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 MEGA 100 FLEX 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 MEGA 100 FLEX 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 MEGA 100 FLEX goes from 20.4 V on its label to about 22.3 V at 20°F and 23 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 0.30% per °C below 77F (25°C), a typical figure, since this panel does not publish its own. At 20F one panel's 20.4 V becomes 22.3 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 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.
