The Haven 10 is an affordable manual transfer switch that allows you to backup essential circuits during a power outage. Use it with your Yeti PRO 4000 to keep lights on, fridges cooling, and personal devices charged.

Build out your backup system with powerful expansion batteries. You can combine as many as 4 Tank PRO 4000 batteries per Yeti PRO. This creates a robust backup system that can run essentials in your home for days on end. And because the system is modular, you can get the expansion batteries you need now and easily add on more in the future when your needs change.

The newly engineered Yeti Link Expansion Module connects Tank Expansion Batteries to your Yeti 1500X and larger X-line power station for increased home backup power.
This kit also includes a 120W power supply for wall charging. NOTE: NOT COMPATIBLE WITH YETI 1000X. Cannot be used at the same time as the Yeti Lithium MPPT Solar Charging Optimization Module.
