The Allpowers R3500 takes up to 2,000 W of solar through one solar input (12–150 V, 40 A, 2,000 W). The quickest refill from a maker panel on sale today: 6 × EcoFlow 400W, 2 in series × 3 strings in parallel on the solar input, which brings it to 2,000 W and refills its 3,168 Wh in about 1.6 h of full sun.

The panels cost $3,594 at EcoFlow, checked Oct 11, 2026. At a more typical 70% panel yield the refill takes about 1.9 h. Every arrangement here keeps the panels' open-circuit voltage under the limit on a -10 °C (14 °F) morning. Every panel we track.

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.

11 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
BLUETTI PV350 and other panels with the same plug: MC4 on the panel and XT60 on the station, so you need an MC4-to-XT60 solar cable. Its cable: 20A MC4 to XT60 Solar Charging Cable (1.5m).
Jackery SolarSaga 100 Prime and other panels with the same plug: Anderson on the panel and XT60 on the station, so you need an Anderson-to-XT60 solar cable. Its cable: 9.58 feet.
Jackery SolarSaga 40 Air and other panels with the same plug: DC8020 on the panel and XT60 on the station, so you need a DC8020-to-XT60 solar cable. Its cable: Multifunctional Solar Charging Cable (5.9 ft/1.8m).
Strings in parallel join through an MC4 branch connector (one Y for each polarity), sold separately.
Panels in series need no extra part: each panel's positive MC4 plug clicks into the next panel's negative.
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.
