Will this solar panel work with my power station?

Verdict
Works
2 x NextGen 220W Bifacial Portable Solar Panel into the DELTA 3 Plus (1 panel on XT60i + 1 panel on XT60i) stays inside 11 to 60 V and under 15 A, even at 20F.

cap 15 A
- 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.
Cables to buy
- Use an MC4 to XT60i solar cable.
- You need this cabling once for each input.
Every wiring option
| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 1 panel on XT60i + 1 panel on XT60i Best option | XT60i + XT60i | 23.5 | 12.4 | 438 | Works |
| 2 panels in series on XT60i | XT60i | 47.1 | 12.4 | 438 | Works |
| 2 panels in parallel on XT60i Total short-circuit current 24.8A is above the 15A the manual allows for this input. The manual says to stay within it to avoid damage. | XT60i | 23.5 | 24.8 | 0 | Don't connect |
Rules we applied
- 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 21.5 V becomes 23.5 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.
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.
