Frequently Asked Questions

Frequently Asked Questions

How do I charge my Yeti Tank Expansion Batteries?

You can recharge your Yeti Tank Expansion Batteries with your wall power supply or Goal Zero Solar Panels using the 8mm input on the Yeti Link Expansion Module. This allows you to recharge your Yeti Tanks with an input up to 150W while they are recharging your Yeti Power Station. For a faster recharge on your Yeti Tanks via Solar you can add the 30A External MPPT Controller. This will allow you to connect more solar panels directly to your Yeti Tanks for a decreased recharge time.

I’m charging my Yeti and it is connected to one or more Tank batteries, but my Tank batteries are not filling up. What should I do?

First, make sure you are using the input on your Link to charge your system. This input is the only way to charge both your Tank(s) and Yeti at the same time. If you are using the correct input and still having a problem, try resetting by reinstalling your Link.
