Read all the instructions and cautions before
Do NOT disassemble or attempt to repair the module.
Do NOT allow water to enter the module, or the Goal Zero
Make sure all connections are tight and secure before using.
Do NOT exceed 22V (350W) input for the module; this can
cause serious damage to the Yeti Lithium and potential
bodily injury. Check third party solar panels specs before
attempting to use them with the module.
Do NOT chain solar panels in series (connecting positive
to negative, positive to negative, etc.), as this can result in
dangerously high levels of voltage that can cause serious
Use ONLY with appropriate Goal Zero Yeti Lithium
WARNING: Never connect a power source to the module before
installing into the Yeti Lithium. Always connect the module to the Yeti
Lithium before connecting any power source.

Portable Power Stations.
WARNING: Do not exceed 22V input for the module under standard
use. Doing so can cause serious damage to the Yeti Lithium and
potential bodily injury. Take note of voltages when using third party
solar panels with the module. Do not chain solar panels in series
(positive to negative, positive to negative, etc.), as this can result in
dangerously high voltages.

HOW IT WORKS
Tools you’ll need: Screwdriver
1. Turn off all the output ports and unplug the Yeti Lithium from any
power source.
2. Open the lid of the Yeti Lithium and remove the expansion module
carriage from the Yeti by removing the six screws and sliding out
the carriage.

3. Take note of the positive and negative terminals on the Yeti’s port, as
well as on the blue connector. Insert the blue module connector into the
module port on the Yeti Lithium, matching positive to positive, negative
to negative.
4. Insert the data transfer connector on the module into the data transfer
port on the Yeti Lithium.
5. Gently set in the Solar Charging Optimization Module into place, tucking
the cables into the opening.
6. Using the provided four screws, secure the module into place.
7. Using the APP or 8mm ports, plug the power source into the module.
8. Know the MPPT is working when the indicator light turns blue.
WARNING: Never connect a power source to the module before
installing into the Yeti Lithium. Always connect the module to the Yeti
Lithium before connecting any power source.
WARNING: Do not exceed 22V input for the module under standard
use. Doing so can cause serious damage to the Yeti Lithium and
potential bodily injury. Take note of voltages when using third party
solar panels with the module. Do not chain solar panels in series
(positive to negative, positive to negative, etc.), as this can result in
dangerously high voltages.

WHAT IS MPPT?
MPPT stands for Maximum Power Point Tracker. The Solar Charging
Optimization Module is an external MPPT and when installed properly,
actively monitors the energy source you’re using to charge the Goal Zero
Yeti Lithium and optimizes the source to maximize power, resulting in up to
40% faster charge times, especially from solar panels. You may also notice
better charge times from AC when utilizing the Yeti Lithium’s AC charging
cable plugged into the module.
FREQUENTLY ASKED QUESTIONS
Q: How many solar panels can I plug into the module?
A: 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 solar experts at
888-794-6250.
Q: Can I plug solar panels into the module and the Goal Zero Yeti Lithium
input ports at the same time?
A: 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.
Q: 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
A: Please call our solar experts at 888-794-6250.
