Will the Renogy E.Flex 200W Portable Solar Panel work with the Goal Zero Yeti 200X?
No. Open-circuit voltage 23.4V is above the station's 22V limit. Going over a station's input voltage limit can damage it. Two panels: don't connect (2 panels in parallel on 8mm), about 0 W.
Don't connect
Do not plug this in. Open-circuit voltage 23.4V is above the station's 22V limit. Going over a station's input voltage limit can damage it.
- Open-circuit voltage 23.4V is above the station's 22V limit. Going over a station's input voltage limit can damage it.
- The brand does not say whether its voltage limit is open-circuit or working voltage, so we check against the stricter open-circuit number.
- The panels can push 9.9A but this input takes 7A, so the station caps it. Safe, you just lose some watts.
- Its AC outlet is modified sine wave, which some devices (and most CPAPs with humidifiers) do not like.

Will the Renogy E.Flex 200W Portable Solar Panel work with the Goal Zero Yeti 200X?
No. Open-circuit voltage 23.4V is above the station's 22V limit. Going over a station's input voltage limit can damage it. Two panels: don't connect (2 panels in parallel on 8mm), about 0 W.
Can I connect two E.Flex 200W Portable Solar Panel panels to the Yeti 200X?
No: Open-circuit voltage 23.4V is above the station's 22V limit. Going over a station's input voltage limit can damage it.
Is it safe on a cold morning?
Panel voltage rises in the cold. One E.Flex 200W Portable Solar Panel goes from 23.4 V on its label to about 25.6 V at 20°F and 26.4 V at 0°F. The Yeti 200X accepts up to 22 V on the 8mm.

- Goal Zero Yeti 200X: solar input 13 to 22 V on the Solar in (8mm). Goal Zero does not say whether this limit is open-circuit or working voltage, so we use the stricter reading: open-circuit voltage on your coldest morning.
- 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 23.4 V becomes 25.6 V.
- Current over the 7 A cap is safe: the station takes 7 A and you get fewer watts. We count only the capped watts.
- Max 100 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.
