Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow DELTA 3 Ultra?

Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow DELTA 3 Ultra: about 27.9 V on a 20°F morning against the station's 60 V limit, and about 175 W in full sun. Two panels: works (2 panels in parallel on Solar input (XT60i)), about 350 W.

Verdict

Works

1 x 175W Rigid Solar Panel into the DELTA 3 Ultra (1 panel on Solar input (XT60i)) stays inside 11 to 60 V and under 18 A, even at 20F.

Quick answers

Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow DELTA 3 Ultra?

Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow DELTA 3 Ultra: about 27.9 V on a 20°F morning against the station's 60 V limit, and about 175 W in full sun. Two panels: works (2 panels in parallel on Solar input (XT60i)), about 350 W.

Can I connect two 175W Rigid Solar Panel panels to the DELTA 3 Ultra?

Yes, 2 panels in parallel on Solar input (XT60i). That gives about 350 W.

What cable do I need to connect the 175W Rigid Solar Panel to the DELTA 3 Ultra?

Use an MC4 to XT60i solar cable.

Is it safe on a cold morning?

Panel voltage rises in the cold. One 175W Rigid Solar Panel goes from 25.5 V on its label to about 27.9 V at 20°F and 28.8 V at 0°F. The DELTA 3 Ultra accepts up to 60 V on the Solar input (XT60i).

All 33 panels checked against the DELTA 3 Ultra

Rules we applied
  • EcoFlow DELTA 3 Ultra: solar input 11 to 60 V on the Solar in (Solar input (XT60i)). 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 25.5 V becomes 27.9 V.
  • Current over the 18 A cap is safe: the station takes 18 A and you get fewer watts. We count only the capped watts.
  • Max 800 W on this input.
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.
