2300W Output for Peak Demand Moments
The EcoFlow STREAM Ultra X provides a leading 2300W AC output, letting you power high-demand appliances through its AC socket using solar energy stored in the battery.
Powers Appliances up to 2300W with a Single Unit.
EcoFlow STREAM Series
Powers appliances up to 2300W by combining 1200W from solar and 1100W from the grid simultaneously.
Traditional Solar Plant System
Powers appliances up to 2300W by combining 800W from solar and 1500W from the grid simultaneously.
EcoFlow STREAM Series
Powers appliances up to 2300W using 100% solar energy.
Traditional Solar Plant System
Powers appliances up to 2300W by combining 800W from solar and 1500W from the grid simultaneously.
When you connect two units in parallel, you can boost the output to 2300W, allowing you to power heavy-duty appliances 100% with solar energy.
Sunset to Sunrise Power: From 3.84kWh to 23kWh
EcoFlow STREAM Ultra X goes beyond industry standards, capturing surplus solar energy during the day to keep you powered through the night — and it scales easily to fit your energy needs.
3.84kWh
With a single unit
23kWh
With 6 units
2 Ways to Scale for Different Needs
Dual Units in Parallel
Connect two STREAM Series units, or pair a STREAM Ultra X with any STREAM Extra Batteries using a Parallel Cable. This setup lets you run heavy-duty appliances up to 2300W, all powered by solar energy.
2 Ways to Scale for Different Needs
Plug-and-Play Decentralised Solar Network
With multiple STREAM products, you can place one near your solar panels and the others anywhere in your home. Once the batteries are plugged into AC sockets, they automatically form a solar network, distributing energy to your devices in the laundry, kitchen, living room, and beyond.
* Both scaling methods require all devices to connect to the same Wi-Fi network. Even without cloud access, seamless operation over your local LAN keeps your energy flowing without interruption.
Capture Every Ray, Maximise Sunlight
Harness the sun's power faster than ever. With four advanced MPPTs and a massive 2000W solar input, the STREAM Battery captures and stores more solar energy, more efficiently.
Don't Let Clouds or Dusk Limit Your Solar Power
The STREAM Battery uses advanced low-light technology to capture energy from even muted skies, delivering up to one extra hour of solar harvest each day compared to industry averages.
AI-Driven Energy, Always Optimised
EcoFlow OASIS doesn’t just answer your energy management questions quickly—it also provides smart analysis and tailored optimisation tips to help you get the most from your system.
AI Mode: Smarter Energy for Dynamic Pricing⁸
EcoFlow’s AI Mode analyses huge amounts of data, including dynamic electricity tariffs, solar forecasts, consumption predictions, and battery status. It can boost your annual savings by up to 29%. If the system predicts cloudy weather, it will automatically charge your battery during low-rate periods to ensure you have enough power for peak times in the evening—maximising your savings without you lifting a finger.
Over 600
Supports over 600 tariff data platforms⁹
Up to 29%
Up to 29% higher savings per year
* For the best results, it's recommended to pair AI Mode with a Smart Meter.
Self-Powered, Fully Customisable
Set your own preferences for battery level, time-of-use pricing, and scheduling. Store solar energy or power your home whenever your battery exceeds your chosen reserve—helping you cut down on grid electricity.
* For the best results, it's recommend to use a Smart Meter.

Compatible with EcoFlow Smart Meter and Smart Plug
Take full control with EcoFlow Smart Meters or Smart Plugs to ensure no power goes to waste. When you connect an EcoFlow Smart Meter with the STREAM Series, they communicate directly, even offline. This allows the STREAM Series to automatically adjust its output to your home grid, with minimal delay.
Works Seamlessly with EcoFlow DELTA Series and PowerOcean
The STREAM Series doesn’t just store solar energy—it shares it intelligently across your EcoFlow ecosystem. Effortlessly transfer surplus solar from STREAM Series to DELTA Series or PowerOcean, and STREAM can also absorb excess solar energy from PowerOcean as needed.
Cross-Brand Ecosystem Harmony
EcoFlow OASIS brings together third-party devices that use Tibber, Matter, and Shelly protocols, all on one unified platform. Enjoy a simpler, more intuitive experience without the hassle of switching between multiple platforms and apps.
