What It Powers

 Yamaha EF2000iS Product Card

PowerTop Version 3 Product Manual

Goal Zero Boulder 50W Solar Panel, 1 Year Warranty. The Boulder 50 Solar Panel is built with strong tempered glass and an aluminum frame with added corner protection for temporary or permanent installation. Equipped with an integrated kickstand to help get optimal angle to the sun. Use with a Goal Zero portable power pack or portable power station to charge your gear day or night.

This panel has an 8mm connector and will easily plug and play with the Sherpa 50, Sherpa 100, Yeti 150 and Yeti 400 for perfect connectivity.

What Can The Boulder 50 Solar Panel Charge?

The solar panel does not hold a charge it produces power when it is exposed to sunlight. You can store the power it produces in a portable recharger. The Boulder 50 can be used to power any Goal Zero power station. If you're looking to recharge things like headlamps, phones, and other USB devices directly from the sun, check out our foldable Nomad Plus Solar Panels.

What Goal Zero Products Work Best With The Boulder 50?

The Boulder 50 can be used to power any Goal Zero recharger. For the amount of Watts it gives, it will be most effective with the Yeti 150, Yeti 400, Sherpa 50 or Sherpa 100.

Does The Boulder 50 Give a Full 50 Watts?

It delivers up to 50 Watts of power, but the angle of the panels and the cloud coverage can impact its performance. Avoid the shade. It will not work indoors.

Product Faqs

Ask a Question

  • Q:The manual mentions cold weather conditions and insulating to keep the battery in good condition, but nothing on hot weather? Would the cells degrade if the lithium battery was out in direct sun especially during summer?

    Hi there,

    Thanks for your question. Every battery including lithium, have a listed operating temperature range, in which they will perform at the highest efficiency.

    Goal Zero Lithium Power Pack's have an operating temperature range of 0-40 C (32-104 F).

    So as long as you are camping within these temperatures, your Goal Zero Lithium Power Pack will perform at it's highest efficiency & remain in good condition.


  • Q:Can I replace the battery in my Goal Zero Yeti 400 Lithium?

    Yes, the battery inside the Goal Zero Yeti 400 Lithium is designed to be easy to replace. Replaceable batteries will be available from GoalZero.com

  • Q:Why is the light on the 12V button blinking on my Yeti 400 Lithium?

    A blinking light on the 12V button indicates the 12V car port has been shut off to protect whatever you have plugged in; you should also see RESERVE MODE blinking on the display. Recharge your Goal Zero Yeti as soon as possible to continue powering your device.

  • Q:How do I know if my device will work with the Goal Zero Yeti 400 Lithium?

    First, you’ll need to determine the amount of power your device requires. This may require some research on your end, a good internet search or examining the user guide for your device should suffice.

    Second, you will need to check the capacity for the individual output ports. For example, the Goal Zero Yeti’s AC port is powered by an inverter that allows for 300W of power. This means if your device is pulling more than 300W for an extended period of time, the Goal Zero Yeti’s inverter will shut off. Another number to watch for is the surge rating of your device as compared to that of the port. The Goal Zero Yeti inverter has an advanced surge management system that will maximize its compatibility with various devices, but there will still be items that will surge at a higher rate, and for a longer time, than the Goal Zero Yeti can manage, in which case the port will turn itself off.

    Finally, once you know your device is compatible, you’ll want to determine how long you’ll be able to power your gear from the Goal Zero Yeti.

    Here’s a quick lesson in power:

    All Goal Zero power packs and solar generators have a number in their name, ex. Guide10 Plus Power Pack, Goal Zero Yeti 400. These numbers refer to the Watt Hours (Wh), or the amount of energy that can be stored in each recharger, and how you’ll know if your gear is compatible with each recharger. For example, a 200Wh recharger should run a 100W light for 2 hours (200/100=2). If your gear falls within the 400Wh capacity of the Goal Zero Yeti, you’ll want to check the restrictions on each of the output ports.

    Another factor in the math is how much power is being converted going from the Goal Zero Yeti battery to the device you are powering/charging. In some situations, like when running a 12V device, such as the LAL 350, directly off the 12V port, there will be no conversion and so no additional losses. In using the USB ports to charge a phone, you add a layer of conversion (12V battery in the Goal Zero Yeti is being converted to a 5V USB output), which introduces around 10% of losses. When using the inverter, there are two layers of conversion (12V to high voltage, DC to AC). The least efficient way of using the battery in the Goal Zero Yeti is to use an AC-DC adapter off the AC ports, as is the case if you use a phone wall charger to charge your phone, as it adds yet another layer of conversion in the wall adapter.

  • Q:What type of battery is in my Goal Zero Lithium Yeti 400 / 1000 / 1400 / 3000?

    Your Goal Zero Yeti Lithium uses custom designed Lithium Ion. Here are some basic facts about Lithium Ion batteries:

    1. Lithium Ion batteries can store and release a lot of energy in a short period of time. The batteries in your Goal Zero Yeti are in a protective enclosure with a sophisticated battery management and protection system controlling its terminals to the outside world.
    2. It is critical that your battery does not get wet as moisture and water can get into the battery cells behind the protection circuitry and bypass that protection.

  • Q:How do I know if my Goal Zero Yeti 400 / 1000 / 1400 / 3000 Lithium is charged?

    To check the charge level of your Goal Zero Yeti, refer to the LCD Battery Display. When lit up, you’ll see a battery outline with 5 segments, indicating the current charge level. It is okay to use your Goal Zero Yeti even when it’s not fully charged.

  • Q:What is the power rating of the 240v socket?

    Hi Grant, 

    Please see below for the ratings of all sockets.

    AC Plug 2x 220V 1.4A, 300W Continuous, 600W Surge Max 

    USB 5V up to 2.1A, 10.5W Max. Regulated 

    6mm Port, 12V, up to 10A, 120W Max.

    12V Cigarette Port, 12V up to 10A, 120W Max.

  • Q:Can I connect a different solar panel brand instead of Goal Zero into my Goal Zero Yeti?

    Hi there,

    All the Yetis come with a solar regulator built-in.

    Any solar panel may be connected to the input, as long as they do not exceed 22 Volts (which most 'camping/caravan' panels don't). You will probably need an adaptor cable to suit the Yeti.

    You cannot connect panels that have built-in regulators, as the regulator needs to 'see' the battery to function, which it won't if connected to a Yeti.
