EcoFlow STREAM AC Pro power bank

EcoFlow STREAM AC Pro 800W power bank

The EcoFlow STREAM AC Pro is a compact energy storage system that works in plug & play mode and allows you to power your home appliances both day and night. It’s sort of like a large, smart powerbank for your home – it charges from an outlet and then powers your appliances when you need it most. It can also support your home’s on-grid system, returning excess power to the grid and helping to reduce your electricity bill. Even if you don’t use solar panels, the STREAM AC Pro saves you money by storing cheaper energy from the grid and giving it back when it’s more expensive – while also acting as an emergency power supply in case of power outages. For those looking for a device with the ability to connect photovoltaic panels, other versions are also available: the EcoFlow STREAM Pro with three MPPT inputs (up to 1,500 watts from PV) and the EcoFlow STREAM Ultra, which offers even more flexibility – as many as four MPPT channels and the ability to connect panels with a total output of up to 2,000 watts.

Built-in battery – power when you need it

The STREAM AC Pro features a 1.92 kWh rechargeable battery to power a variety of home appliances – from routers and computers to refrigerators and lighting. The battery is distinguished by its high durability: it retains 70% of its capacity even after 6,000 charging cycles. Thanks to the self-heating function, the device can charge even in cold conditions – the mechanism automatically activates at 5°C or lower.

On-grid operation and emergency power supply

The device can return energy to the grid with a maximum output of 800 watts (AC Grid-Tied), supporting the current consumption at home. When you need energy immediately, the STREAM AC Pro can power appliances with up to 1,200 watts directly from the battery. If it discharges, the system automatically switches to bypass mode, allowing you to power appliances directly from the grid – with up to 2,300 watts (10 amps). Such an arrangement guarantees stable operation of the system even at higher power demand or when several devices are running simultaneously.

Easy operation and monitoring through the app

Thanks to Wi-Fi and Bluetooth connectivity, the device can be managed from the EcoFlow app. You have access to energy consumption data, can configure charging schedules, remotely turn devices on and off, and use smart AI-based features – available in part in the premium version.

Adapted to different conditions

The STREAM AC Pro’s housing meets IP65 standards – it is dust and splash resistant, so you can also use the device outdoors without worry. The operating temperature range is -20°C to 55°C, and the noise level is kept below 30 dB – the device operates almost silently. The compact housing with dimensions of 255 × 254 × 458 mm and a weight of 21.5 kg facilitates installation in various locations.
