The 12 kWh Backup System
Stay prepared with about 12,000 watt hours of reliable home backup power and the ability to support up to 10 essential circuits. This system includes the Yeti PRO 4000, two Yeti PRO Tank Batteries, and the Haven 10 transfer switch—keeping your home running smoothly during outages.

TANK PRO 4000 HIGHLIGHTS
Modular Scalability
Start with one or two batteries and expand later as your needs grow. The modular design makes it easy to scale your backup system over time.
Increased Capacity
Each Tank PRO 4000 adds substantial storage so you can power more devices for longer. Add multiple units to keep your home running for days.
Easy Integration
Designed to nest seamlessly with the Yeti PRO 4000—once connected, they function as one system, charging and discharging together.
Long Lifespan
Advanced LiFePO₄ battery technology gives the Tank PRO 4000 up to 8× the lifespan of previous models, providing years of reliable backup power.

GOAL ZERO POWER APP
The redesigned Goal Zero app works seamlessly with the Yeti PRO 4000, giving you full control from anywhere. Monitor battery levels, track power flow, and toggle ports on or off. Review historical data to better understand your energy use, and choose charge profiles that prioritize Performance, Battery Saver, or Balance modes—so your power station works exactly the way you need it to.

TURN YOUR YETI INTO A SOLAR GENERATOR
Go fully off-grid by pairing your Yeti with solar panels. Choose from ground-deployable options, roof-mounted panels for vehicles and cabins, or lightweight foldable panels perfect for camping and travel. Stay powered anywhere the sun shines.

HOME BACKUP POWER
Keep your home running during outages with customizable backup solutions. Connect your power station to the Haven 10 Manual Transfer Switch to cover up to 10 essential circuits. Power lights, refrigerators, medical devices, Wi-Fi routers, and more—all with reliable backup when you need it most.
