Will the Rich Solar MEGA 200 PRO (24V) work with the EcoFlow DELTA Pro 3?

Yes. One Rich Solar MEGA 200 PRO (24V) works with the EcoFlow DELTA Pro 3: 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 (1 panel on XT60 (High-PV) + 1 panel on XT60i (Low-PV)), about 400 W.

Verdict

Works

1 x MEGA 200 PRO (24V) into the DELTA Pro 3 (1 panel on XT60 (High-PV)) stays inside 30 to 150 V and under 15 A, even at 20F.

  • The two solar inputs are different. High-PV takes 30 to 150V, Low-PV takes 11 to 60V. A single small panel is too low for High-PV and will not charge there.
  • EcoFlow's manual: panel voltage rises in cold weather, so keep a margin below the limit when wiring in series.
  • For parallel wiring you need Y-branch (T-branch) solar cables.
  • A 24 V panel: 43.5 V open circuit on its own, so two in series (87 V) only suit high-voltage solar inputs.
Cables to buy
  • Use an MC4 to XT60 solar cable.

Quick answers

Will the Rich Solar MEGA 200 PRO (24V) work with the EcoFlow DELTA Pro 3?

Yes. One Rich Solar MEGA 200 PRO (24V) works with the EcoFlow DELTA Pro 3: 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 (1 panel on XT60 (High-PV) + 1 panel on XT60i (Low-PV)), about 400 W.

Can I connect two MEGA 200 PRO (24V) panels to the DELTA Pro 3?

Yes, 1 panel on XT60 (High-PV) + 1 panel on XT60i (Low-PV). That gives about 400 W.

What cable do I need to connect the MEGA 200 PRO (24V) to the DELTA Pro 3?

Use an MC4 to XT60 solar cable.

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 3 accepts up to 150 V on the XT60 (High-PV).

All 33 panels checked against the DELTA Pro 3

Rules we applied
  • EcoFlow DELTA Pro 3: solar input 30 to 150 V on the Solar in 1 (XT60 (High-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, 2,600 W across all inputs.
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.
