EcoFlow STREAM AC Pro Inverter (Battery)

The EcoFlow STREAM AC Pro is a storage inverter for home energy systems, designed to help store electricity and make more efficient use of solar power generated by existing micro-inverters.

The model operates on the principle of AC coupling: it can be integrated into a system with a microinverter via a standard mains connection. This is a convenient solution if solar panels and a microinverter are already installed, but you need to add energy storage without a complete system overhaul.

The battery capacity is 1.92 kWh. This capacity allows you to store surplus energy during the day and use it later — in the evening, at night or during periods of high consumption. This helps to increase the proportion of self-consumption and reduce dependence on the grid.

The STREAM AC Pro has an AC output of up to 1,200 W and supports loads of up to 2,300 W in the appropriate operating mode. Dual sockets allow household appliances to be powered directly from the storage unit, whilst the mains AC output of up to 800 W enables operation within the typical scope of a balcony power station.

Unlike STREAM models with a direct PV input, the STREAM AC Pro is specifically designed to work with existing microinverters and AC systems. It is not a standalone MPPT controller for direct connection to solar panels, but a smart AC battery for expanding your home power system.

Control is available via the EcoFlow mobile app. The device supports Wi-Fi and Bluetooth, so users can monitor charge levels, consumption, operating modes and data history within the app. Full functionality of the STREAM series requires a Wi-Fi connection and the EcoFlow App. :contentReference[oaicite:1]{index=1}

The battery is built using LFP technology and is rated for 6,000 cycles whilst retaining up to 70% of its capacity. This makes the STREAM AC Pro a durable solution for daily use in a home power system.

The casing has an IP65 protection rating, making the device resistant to dust and moisture. The operating temperature range is from -20 to +55 °C, and the built-in self-heating system helps it operate at low temperatures. The noise level is less than 30 dB, so the battery is suitable for installation near living areas.

The EcoFlow STREAM AC Pro can be used as part of the EcoFlow STREAM system, combined with other compatible modules and scaled to increase total capacity. It is a practical solution for those who want to turn solar generation not only into daytime savings, but also into a real energy reserve for the evening and peak loads.
