Goal Zero Yeti Pro 4000 — CleanTechnica Tested - CleanTechnica

The Goal Zero Yeti Pro 4000 is a substantial 4 kWh portable power station designed to bridge the gap between portable outdoor power solutions and home backup energy storage. Weighing over 100 pounds, it includes a detachable wheeled trolley for mobility, though its primary design is for semi-permanent home installation. In home setups, the Yeti Pro 4000 can be wired directly into a home’s electrical system, allowing it to provide backup power to specific circuits or the entire home. Its modular design supports expansion with up to four additional 5 kW battery packs, enabling a total storage capacity of 24 kWh, making it a viable alternative to traditional stationary home energy storage units. Charging options for the Yeti Pro 4000 are versatile and robust, with the ability to draw up to 1,800 watts from a standard AC outlet and accept up to 3,000 watts of solar input, positioning it as a strong candidate for off-grid energy storage.
