Solar generator runtime: rated Wh x 0.85 / average watts. A 1,024Wh unit runs a modern fridge about 14 hours. Six units, ten appliances, sourced draws.

Watts vs watt-hours: watts are power at a moment, watt-hours are energy over time (Wh = W x hours). How to use both to size a solar generator.

How to choose a solar generator: total watts x hours / 0.85 = Wh needed. Capacity vs output, surge, LiFePO4 vs NMC, solar input and 2026 price tiers.

EcoFlow DELTA 3 Ultra: 3072Wh LFP, 3600W AC, TT-30 RV outlet, 800W solar, about $1,299. Runtimes, specs and Ultra vs Ultra Plus.
