At a Glance

This comparison targets buyers choosing between two Goal Zero Yeti stations that sit far apart in capacity and capability. The Yeti Pro 4000 delivers 3993.6 Wh of LFP storage and 3600W of running power, making it a serious home backup contender that powered 47 out of 53 tested devices. The Yeti 1500X, with 1516 Wh and 2000W output, handled 43 of those same devices but tops out well before high-draw appliances.

Cycle life is a major separator: the Pro 4000 offers 4000 cycles versus just 500 for the 1500X, a direct result of its lithium iron phosphate chemistry. Solar input on the Pro 4000 maxes out at 3000W with compatibility across 20 panel options, while the 1500X caps at 600W. The tradeoff is weight and mobility.

At 45.6 lbs, the 1500X is genuinely portable; the 115.7 lb Pro 4000 is not something you casually move around.
