Runtime = 3,195 Wh usable (est. 80% of rated) ÷ the appliance's average draw. Fridges and freezers average their daily energy use; everything else counts as running the whole time. "No" means the load exceeds this model's continuous output or surge rating. Methodology.
Recharge with solar
Solar input: 13.3–150 V, 30 A, up to 3,000 W (HPP).Goal Zero calls it the 'HPP High Voltage Input'. Retailers describe HPP as an Anderson Powerpole-type plug, but Goal Zero's pages do not name Anderson, so this is unconfirmed. The low-voltage input is 8 mm.Describes the single HPP+ high-voltage input that most panel arrays use, through Goal Zero 4:1 series and 3:1 parallel combiners. The guide says 'The Yeti PRO 4000 has two DC inputs': the other is the 8 mm low-voltage input (12.3-28 V, 10 A, 275 W). Panels that fit, fastest first, one panel at a time; days use Dallas, TX's sun (5.4 peak hours a day on average, 4.37 in December). Two or more panels charge faster, up to this station's 3,000 W input limit.

Real-world watts = panel rating capped by this input's current limit (× the panel's voltage at max power) and maximum solar input, × 75%. Peak-sun hours to full = rated capacity (3,994 Wh, since charging fills the whole battery) ÷ real-world watts; days = those hours ÷ peak sun hours per day. Sunnier and cloudier cities are on each panel's page; full method in the methodology.

Usable capacity = this station's usable capacity + each battery's independently measured usable capacity, or 80% of its rated capacity where no test exists ("est."). Runtime uses the same formula as everywhere else on the site. Battery specs come from the brand's official pages.
