EcoFlow STREAM AC Pro Inverter (Battery)

The EcoFlow STREAM AC Pro is a smart energy storage system for balcony power stations and existing solar systems with micro-inverters. The device has been designed to ensure that solar power that has already been generated is not simply fed into the grid unused, but is instead stored temporarily for later use in the home.

Thanks to AC coupling, the STREAM AC Pro can be integrated into existing systems with particular ease. An existing micro-inverter can be connected to the storage unit, allowing the solar system to continue operating whilst being enhanced with a practical storage solution. The installation guide describes how to connect to an existing micro-inverter as well as to the mains supply.

With a capacity of 1.92 kWh, the storage unit is ideal for storing solar energy during the day and making it available later for typical household appliances. This allows you to increase self-consumption and reduce the amount of electricity drawn from the public grid.

The STREAM AC Pro features AC outputs for the direct connection of appliances. The AC outputs allow household appliances to be used flexibly wherever energy is required. The product overview in the manual shows, amongst other things, the AC outputs, mains connection, parallel connection, earth terminal, protective cover, system status LED and AC ON/OFF button. 

The maximum supported appliance power is up to 2,300 W, whilst the standard AC output provides up to 1,200 W. This makes the power bank suitable not only for small appliances but also for many everyday household devices, for example in the kitchen, living area, office or utility room.

The STREAM AC Pro can be conveniently set up and monitored via the EcoFlow app. Once installed, the device is connected in the app and set up for internet use. The manual also explains how to download the EcoFlow app and control the device via your smartphone. 

The power bank supports Wi-Fi and Bluetooth. The Bluetooth and Wi-Fi connections can be reset using the device button if required. In addition, the system status LED provides information on battery level, charging status, firmware updates or any error conditions. 

The EcoFlow STREAM AC Pro is designed for practical, continuous use. The housing is IP65-rated, operation is particularly quiet, and the LFP battery is designed for a long service life. This makes the power storage unit well-suited to modern balcony power stations, where reliability, ease of use and flexible expandability are key.

Another advantage is its modular expandability. EcoFlow STREAM devices support system cascading, which allows the total capacity to be increased. According to the instructions, capacities ranging from 1.92 kWh to 11.52 kWh are possible with up to six units.

For installation, it is important that the mains connection is connected to an earthed socket or an earthing bar. EcoFlow also recommends additionally earthing the housing via the earthing terminal. When working on the domestic electrical circuit, installation must be carried out by a qualified electrician.
