The Anker SOLIX C300X takes up to 100 W of solar through one solar input (11–28 V, 100 W). The quickest refill from a maker panel on sale today: 1 × EcoFlow NextGen 160W, 1 panel on the solar input, which brings it to 100 W and refills its 288 Wh in about 2.9 h of full sun.

Two panels in series add their voltages; strings in parallel add their currents. A panel's open-circuit voltage (Voc) rises on cold, bright mornings, so each arrangement below is checked with the panel's own temperature coefficient, or -0.35% per °C where the maker publishes none, at -10 °C (14 °F). Strings in parallel are kept within the input's current figure; a single string that could give more is held back by the input itself.

5 of the 18 panels fit, fastest refill first. Each uses every input that can take it; the hours are full sun, from empty.

"Full sun to refill" is the ideal floor: the station taking its input limit every hour. Panels rarely deliver their rating, so the 70% column is closer to a good day, and a usable day holds four to six hours of full sun in most of the US. Panels whose maker does not name an MC4 plug are counted one to an input, since they link to others only through the maker's own adapters.
Cables between panel and station
Jackery SolarSaga 200W: DC8020 on the panel and XT60 on the station, so you need a DC8020-to-XT60 solar cable. Its cable: 3 meters.
Jackery SolarSaga 100 Prime: Anderson on the panel and XT60 on the station, so you need an Anderson-to-XT60 solar cable. Its cable: 9.58 feet.
Anker SOLIX does not list a solar cable in the station's own box, so check the panel's box or buy the cable for its plug.
What a day of sun puts back
Watt-hours back in a day, at a 70% panel yield and the station's input limit. Winter in the northern US gives about 3 hours of full sun, a clear summer day in the Southwest 6 or more.
