About this product

The EcoFlow DELTA 3 Ultra Plus takes everything in the DELTA 3 Ultra and adds expandability, faster charging and smarter load control. Its 3,072Wh LFP battery scales to 11kWh, it accepts up to 1,600W of solar and 3,200W from a generator, and Smart Output Priority lets you decide which loads stay on. That makes it a strong foundation for extended outages, remote cabins and mobile communications setups.

Expand From 3kWh to 11kWh

Add up to two DELTA Pro 3 Smart Extra Batteries for 11kWh, or two DELTA 3 Max Plus extra batteries with the Smart Extra Battery Expansion Adapter.

3,600W Output, 7,200W Surge
