Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the EcoFlow DELTA Pro?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the EcoFlow DELTA Pro: about 44.7 V on a 20°F morning against the station's 150 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 400 W.
Works
1 x MEGA 200 PRO FLEX (24V) into the DELTA Pro (1 panel on Solar input) stays inside 11 to 150 V and under 15 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 the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the EcoFlow DELTA Pro?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the EcoFlow DELTA Pro: about 44.7 V on a 20°F morning against the station's 150 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 400 W.
Can I connect two MEGA 200 PRO FLEX (24V) panels to the DELTA Pro?
Yes, 2 panels in parallel on Solar input. That gives about 400 W.
What cable do I need to connect the MEGA 200 PRO FLEX (24V) to the DELTA Pro?
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 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 Pro accepts up to 150 V on the Solar input.

Other panels that work with the DELTA Pro
- EcoFlow DELTA Pro: solar input 11 to 150 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 40.8 V becomes 44.7 V.
- Current over the 15 A cap is safe: the station takes 15 A and you get fewer watts. We count only the capped watts.
- Max 1,600 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.
