Goal Zero Backup Power

Goal Zero's 6th-gen flagship, built like outdoor equipment rather than consumer electronics: aluminum housing, magnetic port covers that snap shut against dust and rain, and UL2743 certification for outdoor portable use - it's the overlanding crowd's pick for a reason. 3,994Wh with 3,600W output (7,200W surge), 3,000W of solar input, and expansion via Tank Pro batteries to roughly 20kWh. It pairs with Goal Zero's Haven 10 transfer switch for 10-circuit home backup. Owners consistently note the fans are quieter than expected for the size, and the build quality feels a class above. The complaints are equally consistent: it's expensive per kWh versus EcoFlow and Anker, Tank Pro expansion batteries cost more than competitors' packs, there's no 240V from a single unit, and Goal Zero's app - historically the brand's weak spot - is improved but still behind EcoFlow's.
