When the power goes out, the main back up system you want to have is a solar generator with a lot of power. One of the most trusted brands out there is Goal Zero, and they officially released the Yeti 1500X on August 17th, 2020.

The Yeti 1500X is a medium-sized solar generator that utilizes its lithium-ion NMC battery to produce a 1516Wh capacity. It is capable of charging much faster than its previous models due to its 600W solar input and MPPT charge controller.

In addition to these improvements, there is also a large inverter capable of handling 2000W of continuous power and 3500W of surge power. This model is also able to be paired with the Yeti App, which Goal Zero made to give users easy access to their solar generators’ functions and data.

All of these features are improvements compared to the Yeti 1500X’s predecessor, the Yeti 1400 Lithium.

The 1400 Lithium looks nearly identical to the 1500X, but the internals have been modified to produce a system that performs better in all major solar generator categories, which include solar input, battery capacity, inverter rating, and charge controller type.

The following is an in-depth comparison of the 1500X and the 1400 Lithium.

Yeti 1500X – Main Differences from the Yeti 1400 Lithium

The Yeti 1400 Lithium

The Yeti 1500X Has a Larger Inverter Than the Yeti 1400 Lithium

The 1500X comes with an inverter rated for 2000W continuous and 3500W surge. This improvement is very significant because you can now power a lot more equipment than the Yeti 1400. The 1400 is rated for 1500W continuous and 3000W surge. It may not seem like a big change at first, but 500 watts can power a lot of necessities when in a pinch.

There’s a Larger Battery in the Yeti 1500X Compared to Its Predecessor

The battery is 1516Wh and has the same basic makeup as the Yeti 1400, both using a Lithium-ion NMC battery. The 1516Wh is a step above the 1425Wh of its predecessor, but it is not a significant jump in capacity.

Faster Wall Charging – Yeti 1500X vs Yeti 1400 Lithium

The Yeti 1400 charges from the wall in approximately 25 hours. This number has been reduced to only 14 hours for the Yeti 1500X. This is an amazing feat of engineering that brings the capabilities of this generator to be more versatile than ever before.

MPPT Charge Controller – Engineered Into the Yeti 1500X

There are a lot of great improvements to the 1500X, but one of the often overlooked ones is the charge controller. People who know solar generators well will know what this is, but for the average consumer, this is gold for this machine.

The 1400 has a PWM charge controller with low battery protection, but the MPPT controller allows for much faster charging via solar panels. Goal Zero claims that with their own solar panels, you will see a 30% more efficient charge, meaning that the power from the solar panel will be able to convert smoothly into the battery for power storage.

For a more in-depth comparison of PWM and MPPT charge controllers, see this short article.

Yeti 1500X Solar Input Massively Improved

Yet another massive improvement from the Yeti 1500X is its ability to attract up to 600 watts of solar power into its system at any given time. This allows for up to 5x faster charging speeds than the included wall adapter, making it easier to power up your generator after depleting its charge.

Regulated Ports Featured in the Yeti 1500X

There are three ports that are now regulated for the Yeti 1500X and they are:

  • The USB-C PD port
  • The 12V car port
  • The Anderson Powerpole port

Why is this important? Having regulated ports is a security measure to make sure that whatever is being charged or powered is getting the exact power required for the device to work properly. Without regulated ports, certain equipment could run at a less-effective rate than it is normally capable of.

The Yeti Mobile Application Comes With the Yeti 1500X

The Yeti App is a feature for specific Goal Zero solar generators. With the Yeti App, you can review power-tracking history, turn ports on and off from your mobile device, and employ different battery modes specific to your needs. The current models that utilize the App are the Yeti 1400 Lithium, Yeti 3000 Lithium, Yeti 1500X, Yeti 3000X, and Yeti 6000X.

This app is unique to Goal Zero and is rare to see amongst other current solar generator brands. The only other solar generator company to my knowledge that has an application for their product is EcoFlow, and the app is currently only designed for the R600 solar generator. See how the R600 application works here.

The Yeti App also has power-tracking history, which allows you to see how much power you’ve used throughout the past day, week, etc.

This is great because you will be able to set specific power modes to your generator so it correlates to patterns of power you’re using throughout each day. This is mostly for people that are using their solar generators on a consistent basis, but the power modes can apply to anyone using their generator with the app.

The current modes that Goal Zero has are:

  • Performance – Using the battery to its full extent
  • Battery Saver – Conserving battery life for essentials
  • Balanced – A mix between “Performance” mode and “Battery Saver” mode
  • Custom – Tailored to your own needs

These modes can be very beneficial for several occurrences including power outages, running certain electronics like the TV, refrigerator, etc., and much more.

Aspects of the Yeti 1500X That Could Use Improvement

Two AC Outlets in the Yeti 1500X

There are only two AC outlets on the Yeti 1500X, which is not ideal for a powerful system like this one. For example, the EcoFlow Delta 1300 has six AC ports and it has about the same sized battery as the 1500X.

This is not ideal because several lights, chargers, and other electronics need AC ports to function.

Of course, an easy solution is to get a powerstrip, but it would have been nice to see at least three to four AC outlets on this generator.

The Yeti 1500X’s AC Outlets Are Very Close Together

The outlets on the 1500X are very close together. If someone is looking to charge their batteries for their camera or something similar, the charging unit for the camera that connects to the AC outlet may be too wide and may cover the other outlet.

This would render the other AC port useless. Nevertheless, this problem could also be solved with a powerstrip.

The Yeti 1400 Lithium & Yeti 1500X Are the Same Weight

The Yeti 1500X weighs 45 pounds, which is the same weight as its predecessor, the Yeti 1400 Lithium. This is an average weight compared to similarly-sized models. To enhance its portability, the Yeti 1500X has a pair of handles for two people to hoist it together.

Some examples of similar solar generators include the Bluetti EB150, which has the same battery capacity as the Yeti 1500X, but it weighs 38 pounds. The EcoFlow Delta 1300, at 1,260Wh of battery capacity (240Wh less than the 1500X), weighs only 30 pounds.

Even though the Yeti 1500X is not a massive solar generator like the Yeti 3000 Lithium, it still would be nice to see it come with a roll cart to make it more portable.

At a Cost of $2,000, the Yeti 1500X Is Expensive

At $2,000.00, the 1500X is one of the most expensive solar generators for its size. That being said, Goal Zero is debatably the best solar generator brand on the market currently.

There is a premium to pay for this generator, but it is built with some of the highest quality of any solar generator. Below I listed some similar models that will give you insight on pricing.

Price Comparison – Yeti 1500X vs Similar Solar Generators

With several medium to large solar generators to choose from, here are a few examples to compare pricing:

Each solar generator listed has a similar battery capacity (within 500Wh) to the Yeti 1500X. As you can see from the examples, only one solar generator (Titan) is more expensive, but it also has 500Wh more than the 1500X.

Recommendations – Buy the Yeti 1500X or Choose Another Brand?

The Yeti 1500X has several advanced features that make it one of the best solar generators for its size. However, these features also make it a very expensive product. You can find similar solar generators that cost $500-$1,000 less. For example, the Bluetti EB150 shares the same battery capacity as the Yeti 1500X but costs $700 less.

If you like Goal Zero and have bought other products and enjoy them, then this product is for you if you like it and have use for it. Besides that, there are several other solar generator models to choose from that will save you hundreds of dollars.
