Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow RIVER 3 Plus?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow RIVER 3 Plus: about 27.9 V on a 20°F morning against the station's 55 V limit, and about 175 W in full sun. Two panels: works (2 panels in parallel on XT60i), about 220 W.
Works
1 x 175W Rigid Solar Panel into the RIVER 3 Plus (1 panel on XT60i) stays inside 11 to 55 V and under 13 A, even at 20F.
- EcoFlow's manual: keep the panel voltage under 55V to avoid damaging the station.
- The solar port is also the car charging port, so you can use one or the other at a time.
- The solar cable (solar to XT60i) is not in the box.
- 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.

| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 2 panels in parallel on XT60i The panels can push 15.7A but this input takes 13A, so the station caps it. Safe, you just lose some watts. | XT60i | 27.9 | 15.7 | 220 | Works |
| 2 panels in series on XT60i Fine in mild weather (51V), but on a 20°F (-7°C) morning the open-circuit voltage rises to about 55.8V, above the 55V limit. Cold makes panels push more voltage. | XT60i | 55.8 | 7.9 | 220 | Works, with a catch |
Quick answers
Will the EcoFlow 175W Rigid Solar Panel work with the EcoFlow RIVER 3 Plus?
Yes. One EcoFlow 175W Rigid Solar Panel works with the EcoFlow RIVER 3 Plus: about 27.9 V on a 20°F morning against the station's 55 V limit, and about 175 W in full sun. Two panels: works (2 panels in parallel on XT60i), about 220 W.
Can I connect two 175W Rigid Solar Panel panels to the RIVER 3 Plus?
Yes, 2 panels in parallel on XT60i. That gives about 220 W.
What cable do I need to connect the 175W Rigid Solar Panel to the RIVER 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 RIVER 3 Plus accepts up to 55 V on the XT60i.

Other panels that work with the RIVER 3 Plus
- EcoFlow RIVER 3 Plus: solar input 11 to 55 V on the Solar in (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 13 A cap is safe: the station takes 13 A and you get fewer watts. We count only the capped watts.
- Max 220 W on this input.
- 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.
