Goal Zero Yeti 1000: Runtime & Specs

Q: How long will the Goal Zero Yeti 1000 run a refrigerator?

About 15 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.

Q: Can the Goal Zero Yeti 1000 run a microwave?

Yes. A typical 1,000 W microwave pulls about 1,500 W from the outlet, within its 2,000 W continuous output. A full battery gives about 34 min of cooking.

Q: How long does the Goal Zero Yeti 1000 take to charge?

Goal Zero's published charging claim: “0–100% in 1.2 hr (0–80% in 0.8 hr)”. Max AC charging power is 1,000 W. With solar, it accepts up to 900 W (600 W per input). With 900 W of panels that's roughly 1.5 hours of good sun from empty.

Q: Is the Goal Zero Yeti 1000 expandable?

No. Its capacity is fixed at 998 Wh.

Q: Does the Goal Zero Yeti 1000 work as a UPS?

Goal Zero lists a 15 ms switchover time, so it can keep devices like routers and computers running when the power drops. Check that your specific device tolerates the switch before relying on it for anything critical.

The Goal Zero Yeti 1000 is a 998 Wh LiFePO4 power station with 2,000 W of continuous AC output and a 3,600 W surge rating. It runs a typical full-size fridge for about 15 hours.
