EcoFlow STREAM AC 5000 Solar Storage Set + 5000 Expansion Battery

EcoFlow STREAM AC 5000 Set + 1× Extra Battery 5000 – Retrofittable AC Storage

This set offers a particularly simple way to add a powerful storage system to existing PV systems or balcony power plants: the EcoFlow STREAM AC 5000 plus 1× STREAM Extra Battery 5000 – together forming a setup that specifically shifts your solar surplus to the evening hours. The system is AC-coupled and is integrated into the home network via a standard outlet – no conversion, no new inverter. 

Why AC coupling is so convenient for existing systems

Many households generate solar power at noon but feed a large part of it into the grid – and then buy electricity back in the evening. Classic home storage systems often involve additional installation effort with existing systems. The STREAM AC 5000 solves this elegantly through AC coupling: It uses the home network as an interface and does not have DC inputs. This means that the inverter, solar panels, and wiring generally remain untouched.

More storage for the evening: 5,024 Wh + 5 kWh expansion

The STREAM AC 5000 comes with 5,024 Wh of storage capacity. With the STREAM Extra Battery 5000, you can easily expand your system by another 5 kWh. This makes the set particularly interesting if you typically need more electricity in the evening – e.g., for the kitchen, home office, or entertainment – and want to give away as little of your daytime surplus as possible.

Plug & Play: Setup via app, commissioning in minutes

The STREAM AC 5000 is connected to the outlet via a Schuko cable, and the EcoFlow App guides you through the setup. No professional is required for basic operation up to 800 W. For power levels above 800 W, a dedicated circuit is recommended.

LiFePO4, emergency power, and UPS: made for everyday use

Inside, LiFePO4 cells ensure long-lasting, safe operation. The storage system is designed for up to 10,000 charge cycles and comes with a 10-year manufacturer warranty.

For emergencies, the STREAM AC 5000 also offers an off-grid output with a continuous power of up to 3,000 W. The UPS function switches over in under 20 ms, so that important devices such as routers or refrigerators can continue to run without interruption.
