EcoFlow STREAM AC Pro Plug-in Home Battery for Existing Solar Systems
The EcoFlow STREAM AC Pro is a plug-and-play AC-coupled home battery designed to work alongside existing solar setups and microinverters or as a standalone battery.
It stores surplus energy during the day and reuses it in the evening, helping reduce grid consumption without requiring a full rewiring or traditional fixed battery installation.
Ideal for users who already have solar (including plug-in balcony/DIY systems), it connects via a standard plug and integrates with EcoFlows app for monitoring, scheduling, and automated energy optimisation.
Key features:
1.92kWh LFP battery capacity (expandable with additional units)
1200W continuous AC output (up to 2300W peak in paired/combined setups)
Plug-and-play AC connection (no inverter replacement required)
Works with most microinverter-based solar systems
Smart app control with energy tracking and automation
Can store excess solar and discharge when demand is higher
Designed for long lifespan (LFP chemistry, multi-thousand cycle durability)
Charge up at night on cheap rates and use during the day
This sits in the plug-in solar battery category rather than a full home storage system, making it more accessible for renters, retrofit solar users, and smaller domestic setups looking to improve self-consumption without major installation work.
