Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the EcoFlow DELTA 3 Ultra Plus?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the EcoFlow DELTA 3 Ultra Plus: about 44.7 V on a 20°F morning against the station's 60 V limit, and about 200 W in full sun. Two panels: works (1 panel on Solar input 1 (XT60i) + 1 panel on Solar input 2 (XT60i)), about 400 W.
Works
1 x MEGA 200 PRO FLEX (24V) into the DELTA 3 Ultra Plus (1 panel on Solar input 1 (XT60i)) stays inside 11 to 60 V and under 18 A, even at 20F.
- A 24 V panel: 40.8 V open circuit on its own, so two in series only suit high-voltage solar inputs.
- Use an MC4 to XT60i solar cable.

Quick answers
Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the EcoFlow DELTA 3 Ultra Plus?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the EcoFlow DELTA 3 Ultra Plus: about 44.7 V on a 20°F morning against the station's 60 V limit, and about 200 W in full sun. Two panels: works (1 panel on Solar input 1 (XT60i) + 1 panel on Solar input 2 (XT60i)), about 400 W.
Can I connect two MEGA 200 PRO FLEX (24V) panels to the DELTA 3 Ultra Plus?
Yes, 1 panel on Solar input 1 (XT60i) + 1 panel on Solar input 2 (XT60i). That gives about 400 W.
What cable do I need to connect the MEGA 200 PRO FLEX (24V) to the DELTA 3 Ultra Plus?
Use an MC4 to XT60i solar cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One MEGA 200 PRO FLEX (24V) goes from 40.8 V on its label to about 44.7 V at 20°F and 46 V at 0°F. The DELTA 3 Ultra Plus accepts up to 60 V on the Solar input 1 (XT60i).

Other panels that work with the DELTA 3 Ultra Plus
- EcoFlow DELTA 3 Ultra Plus: solar input 11 to 60 V on the Solar in 1 (Solar input 1 (XT60i)). 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 40.8 V becomes 44.7 V.
- Current over the 18 A cap is safe: the station takes 18 A and you get fewer watts. We count only the capped watts.
- Max 800 W on this input, 1,600 W across all inputs.
- 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.
