ECOFLOW STREAM ULTRA X

The EcoFlow STREAM Ultra X It represents the definitive evolution of home energy storage systems, designed to maximize energy savings and self-sufficiency through solar energy. With an impressive capacity of 3.84 kWh and an exit up to 2,300 W , this system redefines the standards of balcony batteries, offering performance that far surpasses the competition.

Power Without Compromise

The heart of the STREAM Ultra X system is its ability to deliver 2,300W of power , enough to simultaneously power high-energy appliances like washing machines, refrigerators, and even kitchen appliances. When you connect two units in parallel, you reach this maximum power using 100% solar energy alone, ensuring complete independence from the grid when you need it most.

Energy Storage from Dawn to Dusk

With a basic capacity of 3.84 kWh expandable up to 23 kWh , the STREAM Ultra X captures and stores solar energy produced during the day for use at night and during peak demand. This capacity, 40% higher than the industry standard, dramatically minimizes solar energy waste and maximizes your return on investment.

Advanced 4 MPPT Charging Technology

The system integrates four advanced MPPT controllers which allow solar input up to 2,000 W (500 W for each MPPT), capturing and storing solar energy with higher efficiency than traditional systems. The maximum charging power reaches 1,500 W using the photovoltaic input and the electrical grid simultaneously.

Optimized performance even in cloudy weather

Proprietary technology optimized for low-light conditions allows the STREAM Ultra X to capture energy even when the sky is hazy, ensuring up to an extra hour of energy harvesting compared to the industry average. This means that the system continues to produce energy even in less than optimal weather conditions.

AI Mode: Intelligent Savings up to 29% Annually

Integration with EcoFlow OASIS brings artificial intelligence to home energy management. By analyzing data on dynamic electricity rates, solar forecasts, consumption forecasts, and battery status, the AI Mode Automatically optimizes charging and discharging strategy to maximize savings.

When the system predicts cloudy weather, it automatically charges the battery during off-peak hours, ensuring sufficient power during the evening peak hours. Everything happens completely automatically, without any intervention on your part.

Integrated Ecosystem and Advanced Connectivity

The STREAM Ultra X integrates seamlessly with the EcoFlow ecosystem, compatible with:

• EcoFlow smart meter for real-time consumption monitoring
• EcoFlow Smart Plug for the control of household appliances
• Third-party devices via protocols Tuber, Matter and Shelly
• The direct connection between the smart meter and the STREAM series also occurs offline, allowing the system to automatically adjust the output based on real-time household demand with minimal delays.

Flexible Expansion for Every Need

The system offers two power-up modes :

Dual Unit Parallel : Connect two STREAM Series units to power devices up to 2,300W completely with solar energy.

Distributed solar grid : Place STREAM units in different areas of your home (laundry room, kitchen, living room). Once connected to AC outlets and the same Wi-Fi network, they automatically create a distributed solar grid that powers devices in every room.

Sustainable and Durable Design

Made in Eco-friendly materials without paint , the STREAM Ultra X minimizes environmental impact. The compact, scratch-resistant structure is designed to last, available in finishes wood effect And midnight to perfectly fit the aesthetics of your home. The realistic wood texture adds warmth to spaces, transforming a technological device into a decorative accessory.

Certified Safety and Silent Operation

The system integrates advanced protections at both hardware and software levels, ensuring maximum safety in all operating conditions. With noise emissions of less than 30 dB , the STREAM Ultra X operates in complete silence, making it ideal for any home environment.

There IP65 certification It ensures complete resistance to dust and water jets, allowing it to be used even in outdoor environments such as balconies and terraces.

Extended Temperature Performance

The STREAM Ultra X operates over a wide temperature range, from -20°C to +55°C , with system self-heating battery which activates automatically when charging at low temperatures (≤5°C). This ensures optimal performance in all seasons.

Exceptional Longevity

With 6,000 life cycles before dropping to 70% of the original capacity and With a 10-year warranty , the STREAM Ultra X represents a long-term investment in your home's energy independence.

Real Savings on Your Bill

According to calculations based on the German market, a configuration with 6 Ultra X units combined with 10 x 500W solar panels can generate Annual savings of up to €1,993 , considering a self-consumption rate of 90% and an electricity tariff of €0.40/kWh.

Self-Installation and Maintenance

The system is designed to be installed and maintained independently, without the need for specialized technicians (except in the UK, where connection to the distribution panel requires a certified installer). Its ease of installation makes it accessible to everyone.

Energy Self-Sufficiency During Blackouts

During a power outage, the system automatically detects the grid anomaly and stops feeding power. You can then connect appliances directly to AC outlets to use the internal battery or solar power, keeping essential devices running smoothly.

The EcoFlow STREAM Ultra X It's not just a balcony battery: it's a complete energy system that transforms your home into a self-sufficient smart home, drastically reducing your electricity bill while actively contributing to the energy transition towards renewable sources.
