The Allpowers R4000 takes up to 1,950 W of solar through three solar inputs (each 12–60 V, 13 A, 650 W). The quickest refill from a maker panel on sale today: 3 × EcoFlow 400W, 1 panel on each of its 3 solar inputs, which brings it to 1,200 W and refills its 3,456 Wh in about 2.9 h of full sun.

The panels cost $1,797 at EcoFlow, checked Oct 11, 2026. At a more typical 70% panel yield the refill takes about 4.1 h. Every arrangement here keeps the panels' open-circuit voltage under the limit on a -10 °C (14 °F) morning. Every panel we track.

Allpowers R4000: solar input limits from Allpowers
solar input (×3)
12 to 60 V, 13 A max, 650 W, XT60 plug
All inputs together
1,950 W (Allpowers: "Solar*3: (12~60)V 13A, Single port 650W Max, three ports 2000W Max")
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.

9 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 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).
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.
Allpowers 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.

Type the figures from the panel's label or spec sheet (they are given at 25 °C). The check assumes MC4 plugs, so panels can go in series or parallel.
