Will the EcoFlow 100W Flexible Solar Panel work with the EcoFlow DELTA Pro 3?
Yes. One EcoFlow 100W Flexible Solar Panel works with the EcoFlow DELTA Pro 3: about 22.4 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on XT60 (High-PV)), about 200 W.
Works
1 x 100W Flexible 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 EcoFlow 100W Flexible Solar Panel work with the EcoFlow DELTA Pro 3?
Yes. One EcoFlow 100W Flexible Solar Panel works with the EcoFlow DELTA Pro 3: about 22.4 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on XT60 (High-PV)), about 200 W.
Can I connect two 100W Flexible Solar Panel panels to the DELTA Pro 3?
Yes, 2 panels in series on XT60 (High-PV). That gives about 200 W.
What cable do I need to connect the 100W Flexible 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 100W Flexible Solar Panel goes from 20.3 V on its label to about 22.4 V at 20°F and 23.2 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 0.33% per °C below 77F (25°C), this panel's own figure. At 20F one panel's 20.3 V becomes 22.4 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 this panel's own coefficient from its manual, 0.33% per °C.
- Expected watts are the best case in full sun. Real-world midday output is usually 60 to 80% of that.
