Compatibility and Installation

Which Yeti models fit?

This module installs in the Yeti expansion bay and works with Yeti LI power supplies only — not the X line power supply. Note that the Yeti Link Expansion Module uses the same expansion bay, so choose one module per unit. All Yeti power stations already include integrated MPPT charging; this module adds additional solar input capability for faster recharge on larger Yeti 1000+ units, including the Yeti 1400.

MPPT vs PWM — Do You Need It?

If you're asking whether MPPT beats PWM on a Goal Zero Yeti: your Yeti already has integrated MPPT, so this module's value is added solar input capacity, not a PWM-to-MPPT conversion. That makes it ideal for users stacking panels or shrinking winter recharge windows.
