Will the Rich Solar MEGA 200 PRO (24V) work with the EcoFlow DELTA Pro Ultra?
Yes. One Rich Solar MEGA 200 PRO (24V) works with the EcoFlow DELTA Pro Ultra: about 47.6 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 Low-PV), about 400 W.
Works
1 x MEGA 200 PRO (24V) into the DELTA Pro Ultra (1 panel on Low-PV) stays inside 30 to 150 V and under 15 A, even at 20F.
- A 24 V panel: 43.5 V open circuit on its own, so two in series (87 V) only suit high-voltage solar inputs.
- Use the solar charging cable that came with the station (MC4 on the panel side).

| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 2 panels in parallel on Low-PV Best option | Low-PV | 47.6 | 11 | 400 | Works |
| 2 panels in series on Low-PV | Low-PV | 95.3 | 5.5 | 400 | Works |
| 2 panels in series on High-PV Working voltage 72.6V is below the 80V minimum, so charging may drop out in weak light. | High-PV | 95.3 | 5.5 | 400 | Works, with a catch |
| 1 panel on High-PV + 1 panel on Low-PV Open-circuit voltage 43.5V is below the 80V minimum for this input, so it will not start charging. | High-PV + Low-PV | 47.6 | 5.5 | 0 | Don't connect |
| 2 panels in parallel on High-PV Open-circuit voltage 43.5V is below the 80V minimum for this input, so it will not start charging. | High-PV | 47.6 | 11 | 0 | Don't connect |
Quick answers
Will the Rich Solar MEGA 200 PRO (24V) work with the EcoFlow DELTA Pro Ultra?
Yes. One Rich Solar MEGA 200 PRO (24V) works with the EcoFlow DELTA Pro Ultra: about 47.6 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 Low-PV), about 400 W.
Can I connect two MEGA 200 PRO (24V) panels to the DELTA Pro Ultra?
Yes, 2 panels in parallel on Low-PV. That gives about 400 W.
What cable do I need to connect the MEGA 200 PRO (24V) to the DELTA Pro Ultra?
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 (24V) goes from 43.5 V on its label to about 47.6 V at 20°F and 49.1 V at 0°F. The DELTA Pro Ultra accepts up to 150 V on the Low-PV.

Other panels that work with the DELTA Pro Ultra
- EcoFlow DELTA Pro Ultra: solar input 30 to 150 V on the Solar in 2 (Low-PV). 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 43.5 V becomes 47.6 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, 5,600 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.
