Will the Renogy E.Flex 200W Portable Solar Panel work with the Goal Zero Yeti 500X?

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.

Verdict

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.
Cables to buyNone. Do not connect this combination. Pick a panel with lower open-circuit voltage, or fewer in series.

Quick answers

Will the Renogy E.Flex 200W Portable Solar Panel work with the Goal Zero Yeti 500X?

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 500X?

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 500X accepts up to 22 V on the 8mm.

Rules we applied
  • Goal Zero Yeti 500X: 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 10 A cap is safe: the station takes 10 A and you get fewer watts. We count only the capped watts.
  • Max 150 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.
