Will the EcoFlow 100W Rigid Solar Panel work with the EcoFlow DELTA 2 Max?
Yes. One EcoFlow 100W Rigid Solar Panel works with the EcoFlow DELTA 2 Max: 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 (1 panel on Solar input + 1 panel on Solar input), about 200 W.
Works
1 x 100W Rigid Solar Panel into the DELTA 2 Max (1 panel on Solar input) stays inside 11 to 60 V and under 15 A, even at 20F.
- Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the EcoFlow 100W Rigid Solar Panel work with the EcoFlow DELTA 2 Max?
Yes. One EcoFlow 100W Rigid Solar Panel works with the EcoFlow DELTA 2 Max: 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 (1 panel on Solar input + 1 panel on Solar input), about 200 W.
Can I connect two 100W Rigid Solar Panel panels to the DELTA 2 Max?
Yes, 1 panel on Solar input + 1 panel on Solar input. That gives about 200 W.
What cable do I need to connect the 100W Rigid Solar Panel to the DELTA 2 Max?
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 100W Rigid 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 2 Max accepts up to 60 V on the Solar input.

Other panels that work with the DELTA 2 Max
- EcoFlow DELTA 2 Max: solar input 11 to 60 V on the Solar in 1 (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 0.33% 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 15 A cap is safe: the station takes 15 A and you get fewer watts. We count only the capped watts.
- Max 500 W on this input, 1,000 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.
