Frequently Asked Questions

Frequently Asked Questions

How many solar panels can I plug into the module?

There are three inputs on the module that can be used at the same time; however, do not exceed more than 22V under standard use, as this can result in damage to the Yeti Lithium and potential bodily injury. We recommend chaining solar panels in parallel (positive to positive, negative to negative, etc.). We’ve taken the guesswork out of chaining when using Goal Zero Boulder Solar Panels, the 8mm blue-ringed connector and combiner cables properly chain our panels together for approved use with the Yeti Portable Power Stations. Please call our Customer Support Center at 888-794-6250.

Can I plug solar panels into the module and the Goal Zero Yeti Lithium input ports at the same time?

Yes; however, we recommend using the module’s inputs for solar panels since it can optimize the charging efficiency up to 40%. You may even notice up to 20% more efficiency when charging the Yeti Lithium from the wall when using the module.

Can I use non-Goal Zero solar panels or a custom wiring solution or any solar configuration that may be over 22V open circuit voltage?
