Will the Renogy E.Flex 200W Portable Solar Panel work with the EcoFlow DELTA Pro 3?
Yes. One Renogy E.Flex 200W Portable Solar Panel works with the EcoFlow DELTA Pro 3: about 25.6 V on a 20°F morning against the station's 60 V limit, and about 200 W in full sun. Two panels: works (2 panels in series on XT60 (High-PV)), about 400 W.
Works
1 x E.Flex 200W Portable Solar Panel into the DELTA Pro 3 (1 panel on XT60i (Low-PV)) stays inside 11 to 60 V and under 20 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.
- Use an MC4 to XT60i solar cable.

Quick answers
Will the Renogy E.Flex 200W Portable Solar Panel work with the EcoFlow DELTA Pro 3?
Yes. One Renogy E.Flex 200W Portable Solar Panel works with the EcoFlow DELTA Pro 3: about 25.6 V on a 20°F morning against the station's 60 V limit, and about 200 W in full sun. Two panels: works (2 panels in series on XT60 (High-PV)), about 400 W.
Can I connect two E.Flex 200W Portable Solar Panel panels to the DELTA Pro 3?
Yes, 2 panels in series on XT60 (High-PV). That gives about 400 W.
What cable do I need to connect the E.Flex 200W Portable Solar Panel to the DELTA Pro 3?
Use an MC4 to XT60i solar cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One E.Flex 200W Portable Solar Panel goes from 23.4 V on its label to about 25.6 V at 20°F and 26.4 V at 0°F. The DELTA Pro 3 accepts up to 60 V on the XT60i (Low-PV).

Other panels that work with the DELTA Pro 3
- EcoFlow DELTA Pro 3: solar input 11 to 60 V on the Solar in 2 (XT60i (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 23.4 V becomes 25.6 V.
- Current over the 20 A cap is safe: the station takes 20 A and you get fewer watts. We count only the capped watts.
- Max 1,000 W on this input, 2,600 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.
