Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow DELTA 3 Plus?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow DELTA 3 Plus: 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 (1 panel on XT60i + 1 panel on XT60i), about 350 W.
Works
1 x 175W Rigid Solar Panel into the DELTA 3 Plus (1 panel on XT60i) stays inside 11 to 60 V and under 15 A, even at 20F.
- EcoFlow's manual: keep the total open-circuit voltage within 60V and the total short-circuit current within 15A on each input, or the station can be damaged.
- Short-circuit current is printed on the panel label as Isc. It is a little higher than the working current, so two panels in parallel usually go over 15A.
- If the solar icon on the screen flashes, the light is too weak or the voltage is too high or too low.
- When solar and wall power are both plugged in, the station uses solar first.
- EcoFlow's spec table labels the 7.85 A figure as a voltage; it is the operating current.
- Use an MC4 to XT60i solar cable.

Quick answers
Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow DELTA 3 Plus?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow DELTA 3 Plus: 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 (1 panel on XT60i + 1 panel on XT60i), about 350 W.
Can I connect two 175W Rigid Solar Panel panels to the DELTA 3 Plus?
Yes, 1 panel on XT60i + 1 panel on XT60i. That gives about 350 W.
What cable do I need to connect the 175W Rigid Solar Panel to the DELTA 3 Plus?
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 Plus accepts up to 60 V on the XT60i.

Other panels that work with the DELTA 3 Plus
- EcoFlow DELTA 3 Plus: solar input 11 to 60 V on the Solar in 1 (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.
- EcoFlow says to keep the total short-circuit current (Isc) within 15 A on each input. Over it, we say Don't connect.
- Max 500 W on this input, 1,000 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.
