The EcoFlow STREAM AC 5000 Expansion Battery 5 kWh has been specifically designed to increase the storage capacity of the EcoFlow STREAM AC 5000 Energy Storage System. With an additional 5.0 kWh of LiFePO₄ battery capacity, professional installers can quickly expand existing installations without making major modifications to the original system configuration.
The expansion battery connects directly to the main unit and automatically increases the available storage capacity. Thanks to its modular architecture, the energy storage system can easily grow alongside the homeowner's future energy requirements.
Please note: This expansion battery cannot operate as a standalone unit and is designed exclusively for use with an EcoFlow STREAM AC 5000 Main Unit.
The EcoFlow STREAM AC 5000 Expansion Battery has been engineered to expand existing installations quickly and efficiently.
Once connected to the main unit, the additional battery capacity is automatically recognized within the EcoFlow App. This allows installers to increase storage capacity without complex configuration or additional wiring.
For professional installers, this means shorter installation times and maximum flexibility when upgrading existing residential energy storage systems.
The EcoFlow STREAM AC 5000 platform features a fully modular design.
This makes the system suitable for residential homes as well as larger residential and light commercial applications with higher energy demands.
Adding extra battery capacity allows homeowners to store more excess solar energy instead of exporting it to the electricity grid.
Benefits include:
The EcoFlow STREAM AC 5000 Expansion Battery utilizes premium Lithium Iron Phosphate (LiFePO₄ / LFP) battery cells, renowned for their exceptional safety, long service life, and excellent thermal stability.
Key advantages include:
This advanced battery technology delivers a low total cost of ownership while ensuring reliable long-term performance.
With its IP65 protection rating, the expansion battery is resistant to dust, rain, and harsh environmental conditions.
It is suitable for installation in locations including:
This provides installers with maximum flexibility when designing residential energy storage systems.
