Will the BLUETTI PV100 FX Flexible Solar Panel work with the EcoFlow DELTA Pro Ultra?
Yes. One BLUETTI PV100 FX Flexible Solar Panel works with the EcoFlow DELTA Pro Ultra: about 45.3 V on a 20°F morning against the station's 150 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on High-PV), about 200 W.
Works
1 x PV100 FX Flexible Solar Panel into the DELTA Pro Ultra (1 panel on Low-PV) stays inside 30 to 150 V and under 15 A, even at 20F.
- 41.4 V open circuit is high for a 100 W panel: two in series reach 82.8 V, more than most stations take.
- The BLUETTI US store sells it only in sets of 2 or more.
- Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the BLUETTI PV100 FX Flexible Solar Panel work with the EcoFlow DELTA Pro Ultra?
Yes. One BLUETTI PV100 FX Flexible Solar Panel works with the EcoFlow DELTA Pro Ultra: about 45.3 V on a 20°F morning against the station's 150 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on High-PV), about 200 W.
Can I connect two PV100 FX Flexible Solar Panel panels to the DELTA Pro Ultra?
Yes, 2 panels in series on High-PV. That gives about 200 W.
What cable do I need to connect the PV100 FX Flexible Solar Panel 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 PV100 FX Flexible Solar Panel goes from 41.4 V on its label to about 45.3 V at 20°F and 46.7 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 41.4 V becomes 45.3 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.
