EcoFlow STREAM Standard Balcony Solar System
The EcoFlow STREAM Standard set includes a STREAM microinverter, two Trina 400 W solar panels, and the necessary cables, including PV, AC, two MC4 solar panel extension cables (3 m), and two flat PowerStream MC4 cables. It offers an easy way to start your balcony solar adventure – it is very easy to install and configure. With it, you can power selected devices with solar energy and save on electricity bills! The STREAM microinverter supports two independent MPPT channels, each with an input power of up to 600 W – a total of up to 1200 W from PV panels. It generates up to 800 W of output power at 3.48 A, making it perfect for on-grid systems. You can also control it using the EcoFlow app thanks to the built-in Wi-Fi and Bluetooth.
Better adaptation to working conditions
The EcoFlow Stream microinverter is equipped with two independent Maximum Power Point Tracking (MPPT) channels – each with an input power of up to 600 W. This allows the device to perform better when the panels are installed at different angles or partially shaded. Independent operation of each channel enables more efficient use of available sunlight and reduces energy losses caused by varying sun exposure. What’s more, the microinverter activates with an input power as low as 3 W, allowing it to work early in the morning and just before dusk.
Flexibility in panel selection
The input voltage range from 16 to 60 V DC enables compatibility with a wide range of PV panels. The device is compatible with 99% of the panels available on the market and maintains high efficiency even under low sunlight conditions.
Stable output power to the grid
The EcoFlow Stream 800W operates in on-grid mode – energy flows directly into the home installation, supporting current consumption or feeding surplus energy back to the grid. The STREAM system can generate up to 858 kWh of energy annually, which, at the average European electricity price, can save up to 137 euros. In addition, the microinverter operates stably within a wide grid voltage range – from 183 to 276 V – and frequency range from 45–65 Hz.
Intuitive operation via the app
Thanks to the Wi-Fi and Bluetooth connection, the microinverter can be monitored and configured remotely using the EcoFlow app. There you will find real-time data, consumption forecasts, and AI-based functions: AI-TOU (dynamic energy tariffs), AI Power Prediction, and Adaptive Energy Architect. The AI assistant works 24/7, helping to optimize power consumption. The app also features options like Savings Calendar and remote control of connected devices. Note: some features require an additional premium subscription.
Easy installation – Plug & Play
The installation does not require special tools or the help of an electrician – the entire process takes about 30 minutes. Thanks to the Plug & Play solution, the device can easily be installed independently, even in rented apartments – without permanent alterations to the building structure.
Designed for outdoor use
The microinverter housing meets the IP67 standard, ensuring full protection against dust and splash resistance. The operating temperature range is from -40°C to 65°C, so the device works reliably both in freezing and hot conditions. You can confidently install it outdoors!
Quiet operation and compact dimensions
A noise level below 20 dB makes the device virtually silent. Moreover, thanks to its dimensions of 252 x 180 x 35 mm and weight of 3.2 kg, it is easy to find a suitable installation spot – even where space is limited.
Efficient solar panels included
The set includes two Trina solar panels with a power output of up to 400 W and an efficiency of 21.1%. Thanks to monocrystalline technology and multi-busbar construction, they ensure maximum sunlight utilization and minimal energy losses. As a result, the system operates efficiently even under less favorable lighting conditions! In addition, the compact dimensions and the ability to mount them on a balcony railing make the EcoFlow set with Trina panels a perfect solution for apartments – requiring neither much space nor complicated installation work.
Essential cables
The set also includes the necessary system cables. EcoFlow PowerStream flat MC4 cables allow easy connection of the solar panels to the microinverter placed indoors – without the need to drill holes in the wall. Simply run them through door or window gaps! Meanwhile, 3-meter extension cables offer greater flexibility during installation. They allow you to connect the panels in a way that ensures optimal sunlight exposure. The set also includes AC and PV cables.
