What this station is
The Goal Zero Yeti PRO 4000 stores 3,994 Wh of energy, as announced by the brand. Its outlets can give up to 3,600 W at the same time: add up the watts of everything you plug in and stay under that number. It is a large station: it can keep the essentials of a home going for a day or more, fridge included.
Its battery is LFP (lithium iron phosphate). This type usually keeps most of its capacity after thousands of charges, so it suits a station you use often. At 52 kg, plan two hands or a trolley. Choose where it lives before an outage.
During a power cut
A simple day without power: the internet router on for 24 hours, two LED lamps for 6 hours, a phone charging for 3 hours, and the station itself switched on. That comes to 606 Wh per day. The Goal Zero Yeti PRO 4000 covers about 5.6 days of that.
Add an average fridge (45 W on average) and the Goal Zero Yeti PRO 4000 keeps it going for about 62 h on its own, or 2 days with the basic needs above on top.
Charging it
It accepts up to 3,000 W of solar panels. Even in full sun, a full charge takes at least 1.3 h. In practice panels give less than their rated watts, so count on longer, often a few days in winter.
Questions about this station
How many days of power cut does the Goal Zero Yeti PRO 4000 cover?
About 5.6 days for the basics: router, two LED lamps, a phone and the station itself, 606 Wh per day. Each extra device shortens that time. Try your own list in the calculator.
How long can the Goal Zero Yeti PRO 4000 run a fridge?
About 62 h for an average fridge (45 W on average), or 2 days if you also keep the router, two lamps and a phone going. A big or old fridge uses more.
Can the Goal Zero Yeti PRO 4000 run a CPAP machine all night?
Yes. A CPAP without heated humidifier uses about 12 W. Over 8 hours, with the station itself switched on, that is 176 Wh per night, so about 19.3 nights. The heated humidifier uses much more: turn it off, or use the 12 V cable sold by the CPAP maker.
