The Goal Zero Yeti 1250 is powerful enough to back-up critical appliances - refrigerators and freezers - as well as home health care equipment - heart monitors, oxygen & CPAP machines.

Charge your Goal Zero Yeti 1250 in silence using the free and clean energy of the sun. You can also charge it from the wall. Either way, there are no worries of toxic fumes or the transportation and storage of flammable fuel.

Multiple ports -DC, USB, and AC - make it easy to power all your devices. Activate the ports with one master switch and let everyone in the family help themselves.

Because power is generated silently and cleanly from the sun or the wall, you can operate your Goal Zero Yeti inside the house, cabin, or tent. Our cart makes it easy to move the generator closer to appliances and use shorter extension cords, minimizing power loss and tripping hazards.

I was a bit sceptical at first when the fine ladies and gentleman at Goal Zero described the Yeti 1250 to me as a Solar Generator. A unit that could legitimately replace household power in the field for a substantial amount of time, without using any gasoline, and be completely self-sufficient by having the capability to be charged 100% by solar energy. It was a pretty big claim, so clearly it needed a challenge to match it.After a long day on the trail, I pulled into one of my favorite camp spots, and began to set up camp for the night. Based on my previous experience with the vehicle, I knew there was absolutely no way that the jeep battery would hold a charge overnight, and waking up in the early morning and messing around with electrical wiring didn't sound too appealing. My solution was simple, plug one end of the charger into the power poles located on the rear bumper, and the other end into the Yeti, have a beer, eat a sandwich, and watch The Beatles' Help! on my Macbook Pro(while it was being charged by the AC power of the Yeti of course.) I'd find out in the morning if my crazy scheme would work and save me the distress of getting out into the cold to figure out a better plan.There's absolutely no way you could do this with a traditional generator, as you'd die of CO poisoning while it was running inside the small cabin of the Jeep you are sleeping in. It raises an interesting, and practical point about the green factor that this device has, it doesn't produce any emissions, and if you're charging it via solar energy, it doesn't require any emissions to replenish the battery. Think of the inside of this vehicle as a micro-environment, I'm living in it, right alongside the Yeti, and we're both happy.Check out my whole experience and images here:

Purchased four of the 30 watt panels with the Yeti. Here's how it goes, if you use 100 watts (that's a 100 watt light bulb for one hour), it will take the solar panels four hours to recharge the use. The Yeti hold 1250 watts, so that means you can run one item that uses 500 watts for 2 and a half hours. Using solar to recharge, it will take you three and a half days to replentish the battery. That's at say, 70 watts per hour (6 of their panels), 5 usable hours of sun in the winter, equals 350 watts per day or 3.57 days to charge it again. Hopefully you don't need power the next 3 1/2 days.

This unit uses a laptop computer charger to charge the unit from your house (again, grossly under powered for a battery this size). Also, if you invest in this, keep in mind the charger will reach a temperature in the range of 175 to 190 degrees. It will burn out. Not made to carry a load of this size.

The company staff is very good and helpful. They have tried to help me make this costly boat anchor. Even kind enough to replace the first unit. I now have 6 of the 30 watt panels and best it will do is 73 watts per hour replacement to the battery.

At 120 pounds, you won't be taking this on vacation with you, unless you've got a large group going to take turns carrying it. That doesn't include the tripod and solar panels. The sales photo of it on the kitchen counter would have taken several strong guys or gals to hoist it up there.

The tripods for the panels are poorly designed with legs that can be adjusted, but are kept from folding flat on the ground by a strap. If you have four panels, you'll not set this up by yourself, unless you have four arms.

Still working with the company and now trying understanding how a clear day, isn't a clear day when it comes to solar power. That a 30 watt rated panel is really only capable of producing 10 to 15 watts.

Buy their little solar charger for your cell phone.

Believe me, you will not be able to run anything like the advertizing says. I've tried.

Plus, you'll need additional wiring. Only come with a 8 foot charging cord. Your battery will need to be next to the panels. The Yeti shouldn't be in the direct sun.

Thanks to all the staff for trying to help.

Perfect balance of functionality & sustainability

By bruno68

from New Jersey, United States

Comments about Goal Zero Yeti 1250 Solar Generator:

Wanted a home-scale backup power solution that would have the right features and capacity while also avoiding gas-powered options and including a solar-charging option. This generator checks all the boxes. Love it!


Very Good Product

By Catt

from Smithville, TX

Comments about Goal Zero Yeti 1250 Solar Generator:

I bought this generator a couple of years ago. It works well for what we have used it for, and we are satisfied with it. One thing I would change is to have the controls on the top with a waterproof cover over it. It weighs about 100 lbs, so it is not easy to tilt, and leaning over to read the controls at ground level is difficult and ridiculous. Also, my Mom uses it to run a portable oxygen concentrator when the power goes out, but she has trouble seeing the buttons. They are black on black with tiny print. It looks spiffy, but for an older person, that is very difficult. Specifically, the Display light button is so difficult to see, even I didn't notice it for the first year, and it is intended to help see the screen. You cannot use it, if you cannot see it, so you had to work real hard to see the lcd screen. Overall though we have been happy with it. One thing though, you need to make sure it can run what you want. It is a good generator, but it will not run my Mom's household oxygen concentrator, but only the portable one.. You should check the wattage requirements of the equipment you want to use it for or you may be unpleasantly surprised.

Pricey but saves you in the long run...big time!

By Mitch M

from Montana, United States

Comments about Goal Zero Yeti 1250 Solar Generator:

I bought this just fascinated with the technology. It arrived with its battery charged and ready to go. 24-hours later a rogue blizzard hit my town and knocked out power with temps around -40F. I plugged this beauty into my baseboard heating controller to keep my houses temperature up. In just 24 hours it saved me over 10k in frozen pipe damage. YOU NEVER KNOW WHEN IT WILL COME IN HANDY!!! Just buy it...plug it in...shelve it...and save it for a rainy/snowy day. (Also amazing on camping trips...just saying.)

Nice but has numerous shortcomings

By DocJim

from Denver, CO

Comments about Goal Zero Yeti 1250 Solar Generator:

Not a bad piece of equipment but not made for rugged field operations. Most fuses are internal and if you blow one, you have to take the top off and replace the fuses. The 1250 should have been engineered with re-settable circuit breakers **accessible from the outside of the case** because not everyone who takes this into the field is going to carry spare fuses. In my opinion, the cheap engineering makes this unit unreliable in an emergency.


Off grid boondocking

By BlackMesaResearch

Comments about Goal Zero Yeti 1250 Solar Generator:

I bought this a few weeks ago to power my expedition rv electrical needs. It's too early to give a full review that's why I only gave four stars. So far I'm pleased with this purchase. This is what powers my expedition RVs electrical needs, I also have two Honda EU2000 generators for when solar isn't practical.

Great back-up power.

By Liam

from New Hampshire, United States

Comments about Goal Zero Yeti 1250 Solar Generator:

I purchased the 1250 Yeti a couple of months ago. It's purpose is to keep power sustained to an electric medical bed for a hospice patient living at home. It has worked with outstanding performance and has given us a sense of security no matter what power outages may occur. Thank you Goal Zero.


easy to move.

By jenn2u27

Comments about Goal Zero Yeti 1250 Solar Generator:

This unit is easy to move and also does not take up a lot of space. I love that you can use it in the house with no fear of carbon monoxide poisoning. I like that no one knows I have it and am running it because it is silent.


Goal Zero for Boondocking

By phoonman

from Cedar Park, TX, United States

Comments about Goal Zero Yeti 1250 Solar Generator:

I have mounted the 1250 in my Jeep which is the Tow Vehicle for my T@B Outback. It charges in motion via a roof rack mounted 100w Solar Panel and the 12vdc plug in the Jeep. When boondocking I add the 4 Boulder 30 Panels mounted on the tripod and top it off with a Yamaha 2000 generator, if needed.

Misguided, let down, and frustrated

By Kristine

from Olympia, WA, United States

Comments about Goal Zero Yeti 1250 Solar Generator:

My husband and I were led to believe that we would be able to live in our off grid house of 160 sq ft using the Yeti 1250 and 6 Boulder 30's. This is not true. We had problems from the beginning. 1. All our solar panels were defective, 6 30's would bring in 20-30 watts at full sun , great angles. Replace, thank you. 2. Second set did nothing t work to the best capacity. 3. Yeti at best could run one lamp at night and charge a laptop and two cell phones. tops! In the summer. In the winter, like now, all we get is about an hour of a 6watt led light strand. Nothing else. It dies. 4. Our wall charging cable stopped working. 5. Our battery says full, 100%, in the daytime and at night drops to above said conditions. 6. We paid how much for this? 7. I would love to have a working system, but would never buy and have deterred friends from this company. We have felt so ripped off.
