EcoFlow STREAM Extra Battery 5000

EcoFlow STREAM Extra Battery 5000 (5 kWh) – Modularly Expand Your System

Do you need more storage capacity because your solar power is generated during the day, but your consumption really kicks in in the evening? With the EcoFlow STREAM Extra Battery 5000, you can easily expand your STREAM system by 5 kWh and keep more self-generated energy available for later hours. Thanks to its modular design, your energy system grows exactly as you need it – without having to plan or install a completely new solution right away.

Modular Expansion as Your Energy Needs Grow

Whether you start with STREAM 3000, STREAM 5000, or STREAM AC 5000: the expansion battery integrates seamlessly into the EcoFlow STREAM ecosystem. You can combine different STREAM batteries and scale your system as needed to up to 90 kWh of storage capacity, 18 kW continuous power, and three independently controlled circuits. This keeps your setup flexible – from getting started to a significantly larger expansion stage.

More Self-Generated Solar Power – Even After Sunset

With each additional STREAM battery, your available storage capacity increases. This means that a larger portion of the solar power generated during the day can be stored for the evening hours or periods of higher energy demand, rather than going unused.

Designed for Everyday Use

The STREAM Extra Battery 5000 supports a charging and discharging power of up to 1,800 W and is therefore perfectly matched to the STREAM platform. For long-term everyday use, it is designed to last for many years: up to 10,000 charge cycles, self-heating battery technology for reliable operation even at low temperatures, and a 10-year warranty for additional planning security.

Compact, Quiet, and Flexible Placement

Despite a storage capacity of over 5 kWh, the battery remains pleasantly compact (295 × 519 × 267 mm) and operates almost silently at less than 20 dB. Thanks to its IP65 rating, the enclosure is designed for various conditions, making installation possible in the utility room, technical room, or another suitable location.
