EcoFlow STREAM Ultra X

The EcoFlow STREAM Ultra X is the bigger sister of the STREAM Ultra: 3.84 kWh of LFP storage in the same plug and play unit, with a built-in 800 W microinverter and four MPPT inputs taking up to 2000 W of panels, 500 W and one panel per input. The system reaches 23 kWh by connecting up to six STREAM units, and the unit's own sockets power appliances up to 1200 W. No building work and no electrician — the panels connect by MC4 and the unit plugs into a domestic socket. From 28 August 2026, Portugal's self-consumption rules (Decreto-Lei 130/2026, amending Decreto-Lei 15/2022) no longer require a registered installer or responsible technician up to 800 W of installed power, and waive DGEG registration as long as no surplus is fed into the grid. It stores the day's solar surplus for the evening and, with AI-TOU in the EcoFlow app, charges during off-peak hours to discharge at peak. IP65, battery self-heating in cold weather and natural convection cooling, with no fans. 6000 cycles and a 10-year warranty.
