Description
Product information
EcoFlow STREAM Easy Flex Balcony Solar System
The EcoFlow STREAM Easy Flex kit includes a STREAM microinverter, two Sunman SMF200J 200 W solar panels, and necessary cables, including PV and AC. It allows you to easily 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 your electricity bills! The STREAM microinverter supports two independent MPPT channels, each with an input power of up to 600 W – totaling 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 via the EcoFlow app thanks to 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) paths, each with an input power of up to 600 W. This enables the device to handle situations where panels are set at different angles or partially shaded. Independent operation of each channel ensures more efficient use of available sunlight and reduces energy losses due to varying sunlight conditions. Moreover, the microinverter activates with an input power as low as 3 W, allowing it to operate early in the morning and just before sunset.

Flexibility in Panel Selection
An input voltage range of 16–60 V DC allows compatibility with a wide range of PV panels. The device is compatible with 99% of panels available on the market and maintains high efficiency even under low sunlight.

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 back into the grid. The STREAM system can generate up to 858 kWh of energy annually, saving up to 137 euros based on the average European electricity price. Additionally, the microinverter operates stably across a wide grid voltage range – from 183 to 276 V – and frequency from 45–65 Hz.

Intuitive Control via App
Thanks to Wi-Fi and Bluetooth connectivity, the microinverter can be monitored and configured remotely using the EcoFlow app. You will find real-time data, consumption forecasts, and AI-based features: AI-TOU (dynamic energy tariffs), AI Power Prediction, and Adaptive Energy Architect. The AI assistant works 24/7 to help optimize energy consumption. The app also offers functions like Savings Calendar and remote control of connected devices. Note: Some features require an additional premium subscription.

Easy Installation – Plug & Play
Installation does not require specialized tools or the help of an electrician – the entire process takes about 30 minutes. Thanks to the Plug & Play solution, the device can be easily installed independently, even in rented apartments – without permanently altering the building structure.

Outdoor Ready
The microinverter's enclosure meets the IP67 standard, offering complete protection against dust and resistance to splashes. The operating temperature range is from -40°C to 65°C, ensuring reliable operation during both frosts and heatwaves. You can successfully install it outdoors!

Quiet Operation and Compact Size
A noise level below 20 dB makes the device virtually inaudible. 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 in limited spaces.

Efficient Solar Panels Included
The kit includes two Sunman SMF200J photovoltaic panels, which, thanks to 60 monocrystalline cells, achieve 16.9% efficiency and a maximum power of 200 W. Thanks to innovative eArc technology, they combine proven crystalline silicon cell performance with a flexible composite material only 2 mm thick. They are about 70% lighter and up to 95% thinner than traditional glass panels while offering equally high durability and damage resistance.

Lightweight, Flexible, Durable
The Sunman SMF200J panel weighs only about 2.6 kg, and its dimensions are 1159 x 1026 x 2 mm, making it very easy to transport! Moreover, the flexible, frameless design eliminates the need for heavy mounts and aluminum frames. The panel can be glued directly to the surface – no drilling and no damage to waterproofing layers – significantly speeding up and simplifying installation. The minimum bending radius of 0.5 m allows it to be mounted even on slightly curved surfaces. Furthermore, the SMF200J model complies with the IEC 61215 and 61730 standards and features an IP68 rating, offering full dust and water resistance.
