EcoFlow STREAM AC Pro 1.92kWh Storage LiFePO4 2300W

The EcoFlow STREAM AC Pro (MPN: EFSTREAMACPro800W-EU) is a powerful, off-grid storage solution with integrated AC coupling that integrates seamlessly into existing microinverter systems without any modifications. Simply plugged into a power outlet, it stores excess solar energy and makes it available efficiently when needed—even during a power outage. With an output power of up to 2,300 W and a bidirectional inverter (1,200 W), the AC Pro covers most of your household needs. Its modular expandability up to 11.52 kWh and AI-supported energy management make it the ideal solution for energy-independent households. In combination with intelligent tariff usage (TOU) and accurate solar forecasting, annual electricity cost savings of up to $412 can be achieved. The AC Pro is also compatible with the EcoFlow STREAM Ultra and STREAM Pro and can be seamlessly integrated into these systems—ideal for anyone who wants to maximize their self-consumption while minimizing their electricity bill.

*Save up to $412 in electricity costs

The EcoFlow Stream AC Pro generates 1,041 kWh of solar energy per year. With an average annual electricity consumption of 3,113 kWh for a German household, the system covers around 33.4% of the total demand—both during the day and at night by storing solar power. At an electricity price of $0.40/kWh, this results in annual savings of around $412. However, actual savings may vary depending on individual consumption patterns and electricity price fluctuations.

Seamless integration via AC coupling

Thanks to AC coupling technology, the STREAM AC Pro can be easily connected to a standard household outlet. Integration into existing micro-inverter systems is possible without any modifications or additional cabling. This allows users to expand their solar system flexibly and easily.

Flexibly expandable

The basic capacity of 1.92 kWh can be expanded modularly to up to 11.52 kWh by connecting up to six STREAM AC Pro units or in combination with batteries from the EcoFlow DELTA series. This makes the system suitable for a wide range of household sizes and increasing energy requirements.

Intelligent energy management with AI

The integrated AI system recognizes consumption patterns, analyzes tariff data, and automatically redirects energy as needed. For even distribution, energy from other units is switched on when one unit reaches its capacity limit. This ensures a continuous supply and optimal utilization of the stored electricity.

Dynamic electricity tariff usage (TOU model)

The Time-of-Use (TOU) model analyzes electricity prices from sources such as Nord Pool, Epex Spot, or Tibber in real time. The system automatically charges when prices are low and feeds in when prices are high—for maximum savings through intelligent tariff usage.

High-precision weather forecast

Through Solcast integration, the system processes over 100 million weather and solar forecasts per hour. Satellite data, geolocation, historical weather data, and typical meteorological years (TMY) ensure accurate energy planning.

Smart meters and smart plugs for efficient use

Through collaboration with providers such as Shelly and Tibber, your energy consumption is controlled fully automatically by smart meters, smart plugs, and the EcoFlow app. This allows you to operate e-bike charging stations, garden pumps, or ventilation systems specifically with surplus solar power—instead of feeding it into the grid.
