EcoFlow STREAM Ultra X – Powerful Energy Storage for Maximum Savings

The EcoFlow STREAM Ultra X offers powerful indoor energy storage with a capacity of 3.84 kWh, ideal for those who want to utilize more solar energy and drastically reduce their energy bills. Thanks to advanced AC coupling, high compatibility, and ease of use, this system is perfect for both renters and homeowners.

Powerful Performance & Maximum Savings

Up to €1993 savings per year thanks to 2000W solar input with a 4-MPPT design and an additional 800W via connected micro-inverters. Two AC outputs (1200–2300 W) power 99% of all household appliances – from refrigerators to coffee machines.

Plug & Power for Indoor Use

Place the STREAM Ultra X flexibly in your home and connect it easily. With AC coupling, you can directly use stored solar energy for daily appliances without complex installations.

Flexibly Expandable up to 23 kWh

Start with 3.84 kWh and expand effortlessly up to 23 kWh. A maximum of 6 units can be linked for complete energy autonomy.

Durable, Safe, and Space-Saving

Equipped with an LFP battery with 6000 charge cycles and a 15-year lifespan. With IP65 protection, the system operates reliably down to -20°C. The quiet, compact design (only 30 cm wide) fits in narrow spaces, and the hidden cabling seamlessly integrates into any interior.

Advanced AI Control

The EcoFlow App analyzes energy prices, usage patterns, and system status in real-time. The AI automatically optimizes the TOU strategy, thereby increasing savings. With 24/7 management, you always see exactly how much energy you consume and store.

Plug & Play Installation

No electrician needed – no drilling or damage to walls. Plug & Play installation makes the STREAM Ultra X ideal for any home and offers flexibility when moving or redecorating.

Achieve Near Full Solar Autonomy

Multiple batteries from the EcoFlow STREAM series form an AI-controlled energy network that automatically distributes excess solar energy between rooms. This increases your self-consumption and reduces your dependence on the grid.

Legal notes

The plug-in solar device must be connected by an electrical company registered with the grid operator and must be registered with the grid operator by a registered electrical company. These obligations expire under the new legislation (from May 2024) for a privileged plug-in solar device with a total installed capacity of up to 2 kilowatts and an inverter capacity of up to 801 volt-amperes. In this case, only registration with the Bundesnetzagentur's Market Master Data Register is required. For further legal obligations, the buyer must inform themselves independently.
