Will the Rich Solar MEGA 50 work with the EcoFlow RIVER 2?
Yes. One Rich Solar MEGA 50 works with the EcoFlow RIVER 2: about 22.8 V on a 20°F morning against the station's 30 V limit, and about 50 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 100 W.
Works
1 x MEGA 50 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).

Quick answers
Will the Rich Solar MEGA 50 work with the EcoFlow RIVER 2?
Yes. One Rich Solar MEGA 50 works with the EcoFlow RIVER 2: about 22.8 V on a 20°F morning against the station's 30 V limit, and about 50 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 100 W.
Can I connect two MEGA 50 panels to the RIVER 2?
Yes, 2 panels in parallel on Solar input. That gives about 100 W.
What cable do I need to connect the MEGA 50 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 MEGA 50 goes from 20.8 V on its label to about 22.8 V at 20°F and 23.5 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 20.8 V becomes 22.8 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.
