Stable 800 W output for everyday devices

With up to 800 W AC output, the EcoFlow STREAM AC is ready to support a wide range of household electronics and appliances. It’s a great fit for devices like routers, lamps, televisions, and other low-to-medium power equipment, helping you stay powered when solar generation drops or during a power outage.

Smart energy management with the EcoFlow app

Manage your system in real time with the EcoFlow app. The built-in AI-TOU model analyzes electricity tariffs every 60 minutes and can automatically charge the unit when energy is cheaper, then use stored power when rates are higher. That means more efficient energy use and real savings with less manual planning. The system also uses Solcast solar forecasts to predict solar production and optimize charging. Please note: selected app features may require a premium subscription.

Works with smart meters and smart plugs

The STREAM AC can cooperate with smart meters, smart plugs, and the EcoFlow app to direct surplus solar energy exactly where it is needed. This helps keep more of your self-generated electricity at home, whether you want to charge an e-bike, run ventilation equipment, or support an irrigation system.

Premium safety for long-term use

The EcoFlow STREAM AC is engineered for reliable, long-lasting performance. Its multi-layer protection system helps guard against issues such as overload and overheating, while fast voltage drop to a safe level during disconnection helps protect your home installation. The housing features aerogel insulation for improved fire resistance, and compliance with recognized standards supports both safety and data protection.

Reliable in tough conditions

Designed for year-round use, the STREAM AC operates in temperatures from -20°C to 55°C. Its self-heating function enables safe operation even on cold winter days, while the IP65-rated enclosure provides strong resistance to rain and dust. This means you can install it both indoors and outdoors. The unit also uses LFP (lithium iron phosphate) cells, offering around 6000 charge cycles while retaining 70% capacity – translating into up to 15 years of dependable service.

Compact design and whisper-quiet operation

With a noise level below 30 dB, the STREAM AC runs quietly enough for placement in a living room or even a bedroom. Its slim, upright form saves floor space and blends naturally into modern interiors, making it a practical and stylish choice for home energy storage.
