Calculated scenario · sourced manifest
37 stations cover the sourced energy and running load; 42 fail at least one check. No source publishes a startup surge for RV refrigerator (Dometic RC10 class), so this plan cannot confirm any station will start it.

Average draw applies each sourced duty cycle; energy is average draw × quantity × daily hours × scenario days.

02 · Reading the plan
At 636 Wh a day this is the smallest plan on the site, and its proportions are the surprise. Four LED lamps burning for six hours are 216 Wh — 34% of the day, more than three times the share lighting takes on any other scenario here — against 420 Wh for a refrigerator that runs around the clock. Lighting feels free because a single bulb is 9 W. In a plan this small nothing is free: four of them together draw 36 W, against the cold box's 50 W.
Sizing for the appliance and ignoring the evening. Every instinct says the refrigerator is the plan and the lamps are trim, and by energy that is two-thirds true — but the trim is the only part of this you control. The 420 Wh is set by a thermostat, while the 216 Wh is set by how many lamps are on and for how long: cutting the evening from six hours to four gives back 72 Wh, more than a tenth of the whole day, and costs nothing but a decision.
A plan this small exposes a cost our arithmetic does not carry. The lamps run on AC, so the station holds an inverter awake for six hours in order to serve 36 W — and while we charge the conversion loss on that 216 Wh, we do not charge the inverter's own idle consumption, because no manufacturer in this catalogue publishes it. On an eight-kilowatt day that omission is noise; on a 636 Wh day even a small constant draw is a real fraction of the answer, and it is the number we would most like to have and cannot get. The refrigerator figure carries its own caveat: it describes a cabinet in a parked rig at moderate temperature, not one sitting in afternoon sun.

Lightweight fit
Why it fits
16.2 kg, 1.2 kg above the 15 kg preferred limit
Main compromise
1.7 kg heavier than the lightest eligible model (36 of 37 eligible models have this sourced value)
Best all-round fit
Why it fits
74.9 BatteryRank score — the highest of any station that fits this plan
Main compromise
4.8 points below the highest-scoring eligible model (36 of 37 eligible models have this sourced value)
Longer off-grid stay
Why it fits
8 projected runtime days
Main compromise
9 days less projected runtime than the longest-running eligible model across 37 eligible models
Solar balance
On EcoFlow DELTA Pro Ultra X, the configured 200 W array harvests 560 Wh/day.
The remaining deficit is 161 Wh/day, for about 76.4 days of modeled runtime.
