Will the Renogy E.Flex 200W Portable Solar Panel work with the Anker SOLIX C300X?

Yes. One Renogy E.Flex 200W Portable Solar Panel works with the Anker SOLIX C300X: about 25.6 V on a 20°F morning against the station's 28 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on XT60), about 100 W.

Verdict

Works

1 x E.Flex 200W Portable Solar Panel into the C300X (1 panel on XT60) stays inside 11 to 28 V, even at 20F. The station caps the current at 8.2 A.

  • 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 8.2A, so the station caps it. Safe, you just lose some watts.
  • Anker's page: use only 11 to 28V panels with an XT60 plug.
Cables to buy
  • Use an MC4 to XT60 solar cable.

Quick answers

Will the Renogy E.Flex 200W Portable Solar Panel work with the Anker SOLIX C300X?

Yes. One Renogy E.Flex 200W Portable Solar Panel works with the Anker SOLIX C300X: about 25.6 V on a 20°F morning against the station's 28 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on XT60), about 100 W.

Can I connect two E.Flex 200W Portable Solar Panel panels to the C300X?

Yes, 2 panels in parallel on XT60. That gives about 100 W.

What cable do I need to connect the E.Flex 200W Portable Solar Panel to the C300X?

Use an MC4 to XT60 solar cable.

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 C300X accepts up to 28 V on the XT60.

Rules we applied
  • Anker SOLIX C300X: solar input 11 to 28 V on the Solar in (XT60). Anker SOLIX 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 8.2 A cap is safe: the station takes 8.2 A and you get fewer watts. We count only the capped watts.
  • Max 100 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.
