Will the Rich Solar MEGA 200 work with the EcoFlow RIVER Max Plus?

Yes. One Rich Solar MEGA 200 works with the EcoFlow RIVER Max Plus: about 23.9 V on a 20°F morning against the station's 25 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 200 W.

Verdict

Works

1 x MEGA 200 into the RIVER Max Plus (1 panel on Solar input) stays inside 10 to 25 V and under 12 A, even at 20F.

The panels can push 21.8A but this input takes 12A, so the station caps it. Safe, you just lose some watts.

Quick answers

Will the Rich Solar MEGA 200 work with the EcoFlow RIVER Max Plus?

Yes. One Rich Solar MEGA 200 works with the EcoFlow RIVER Max Plus: about 23.9 V on a 20°F morning against the station's 25 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 200 W.

Can I connect two MEGA 200 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 200 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 200 goes from 21.8 V on its label to about 23.9 V at 20°F and 24.6 V at 0°F. The RIVER Max Plus accepts up to 25 V on the Solar input.

Rules we applied
  • 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 21.8 V becomes 23.9 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.
Assumptions
  • 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.
