The EcoFlow STREAM Ultra X is a powerful and smart hybrid home battery with a capacity of 3.84 kWh, designed for anyone who wants to store and use self-generated solar energy smartly – without complicated installation. This plug & play battery is connected directly to the socket, after which you fully manage the system via the user-friendly EcoFlow app. Whether you want to save energy for the evening, save on your energy bill, or need a backup in the event of a power outage: the STREAM Ultra X makes it possible.
Ready to use, without installer: Connect the battery from a regular wall outlet – no inverter or complex installation required.
Storage capacity of 3.84 kWh per battery: Enough to power your refrigerator, lighting, router and other essential appliances for hours.
Expandable to 23 kWh: Connect up to 6 batteries together for a total of 23.04 kWh of energy storage – scalable for larger households.
Feeding back into the grid: Feeds up to 1,200 W back to the grid (if connected to its own group). On a shared group, feed-in is possible up to 600 W (NL) or 800 W (BE).
Solar charging up to 2,000 W: Connect up to 4 x 500W solar panels for instant, renewable energy storage – MPPT charge controller integrated.
Bypass function up to 2,300 W: Thanks to forward current, you can also power heavier devices via the integrated socket (1,200 W from battery + 1,100 W from mains power).
Smart control via intermediate meter: For fully automatic charging and discharging, couple an EcoFlow or Shelly Smart Meter – the system then works completely independently.
App control & timetables: Without an intermediate meter, you easily set charging times manually via timetables in the EcoFlow app.
Weatherproof & quiet: With an IP65 rating and whisper-quiet operation (<30 dB), the STREAM Ultra X is suitable for indoor and outdoor use.
Self-heating in cold temperatures: This battery also performs excellently in winter conditions, thanks to built-in heating.
Home energy storage without hassle: Perfect for those who want to use solar power when it’s really needed – without installation or technical knowledge.
Smart saving on power costs: Charge during off-peak hours or with solar, use your power at night – ideal with dynamic energy tariffs.
Emergency outage power: Stay online and active when the grid goes down – power lights, internet, refrigerator and more with your own stored power.
Growable energy storage: Start with one battery and scale up to 23 kWh as your energy needs grow or your solar panels expand.
Solar panel storage without an inverter:Ideal for those who already have panels or want to work off-grid without complicated configuration.
