The OUPES Mega 1 takes up to 800 W of solar through one solar input (12–78 V, 14 A, 800 W). The quickest refill from a maker panel on sale today: 1 × Jackery SolarSaga 500 X, 1 panel on the solar input, which brings it to 500 W and refills its 1,024 Wh in about 2 h of full sun.

The panels cost $799 at Jackery, checked Oct 11, 2026. At a more typical 70% panel yield the refill takes about 2.9 h. Every arrangement here keeps the panels' open-circuit voltage under the limit on a -10 °C (14 °F) morning. Every panel we track.
1 × Jackery SolarSaga 500 X on the OUPES Mega 1: 1 panel on the solar input; 500 W in.
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.

12 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 100 Prime and other panels with the same plug: Anderson on both, so the panel plugs straight in. Its cable: 9.58 feet.
BLUETTI PV350 and other panels with the same plug: MC4 on the panel and Anderson on the station, so you need an MC4-to-Anderson solar cable. Its cable: 20A MC4 to XT60 Solar Charging Cable (1.5m).
Jackery SolarSaga 40 Air and other panels with the same plug: DC8020 on the panel and Anderson on the station, so you need a DC8020-to-Anderson solar cable. Its cable: Multifunctional Solar Charging Cable (5.9 ft/1.8m).
OUPES 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.
