EcoFlow STREAM Advanced balcony photovoltaics

The EcoFlow STREAM Advanced kit includes a STREAM microinverter, two Trina 400 Watt photovoltaic panels, two panel mounts, a Smart Plug and the necessary cables. It allows you to easily start the adventure of balcony photovoltaics - it is very easy to install and configure. With it you can power your chosen devices with solar energy and save on bills! The STREAM microinverter supports two independent MPPT (Maximum Power Point Tracking) channels, each with an input power of up to 600 watts - together that's as much as 1200 watts from PV (Photovoltaic, photovoltaic) panels. It generates up to 800 W of output power at 3.48 A, ideal for on-grid (grid-connected) systems. You can also control it with the EcoFlow app thanks to built-in Wi-Fi and Bluetooth.

Real savings

A set of 2 photovoltaic panels with 400W each is a smart solution for your home, producing up to 842 kWh of clean solar energy per year. This can save you up to867.64 PLNon your electricity bills at the current energy price in the G11 tariff (PLN 1.03/kWh)*. It's a compact investment that starts working for your household budget from day one, turning solar energy into tangible financial savings.

Better adaptation to operating conditions

The EcoFlow Stream microinverter features two independent maximum power point tracking (MPPT) circuits - each with an input power of up to 600 watts. This allows the unit to better handle situations where panels are positioned at different angles or part of them are in the shade. Independent operation of each channel allows more efficient use of available sunlight and reduces energy losses caused by varying sunlight conditions. What's more, the microinverter activates with an input power of just 3 watts, allowing it to operate early in the morning and just before dusk.

Flexibility in panel selection

The input voltage range of 16 to 60 V DC (Direct Current, DC) allows it to work with a wide range of PV panels. The device is compatible with 99% of the panels on the market and maintains high efficiency even in low sunlight.

Stable output power to the grid

The EcoFlow Stream 800W operates in on-grid mode - the energy goes directly to the home system, supporting current consumption or returning surplus to the grid. The STREAM system can generate up to 858 kWh of energy annually, saving up to €137 at the average European electricity price. In addition, the microinverter operates stably over a wide range of grid voltage - from 183 to 276 V - and frequency of 45-65 Hz.

Intuitive operation via an app

Thanks to Wi-Fi and Bluetooth connectivity, the microinverter can be monitored and configured remotely via the EcoFlow app. You'll find real-time data, consumption forecasts and artificial intelligence-based features: AI-TOU (dynamic energy tariffs), AI Power Prediction and Adaptive Energy Architect. AI Assistant works 24/7 to help optimize power consumption. The app also includes features such as Savings Calendar and remote control of connected devices. Note: some of these options require an additional premium subscription.

Easy installation - Plug & Play

Installation requires no specialized tools or electrician's help - the whole process takes about 30 minutes. Thanks to the Plug & Play solution, the device can be easily installed by yourself, even in rented apartments - without any permanent interference with the building structure.

Adapted for outdoor operation

The microinverter's housing meets the IP67 standard (Ingress Protection 67, protection against dust and immersion in water), which means full protection against dust and splash resistance. The operating temperature range is -40°C to 65°C - so the device works reliably in both freezing and hot weather. You can successfully mount it outdoors!

Quiet operation and compact dimensions

With a noise level of less than 20 dB, the device remains virtually inaudible. In addition, 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 place for it - even where space is limited.

Efficient photovoltaic panels included in the kit

The kit includes two Trina photovoltaic panels with up to 400 watts of power and an efficiency of 21.1%. Thanks to monocrystalline and multi-bay technology, they ensure maximum utilization of sunlight and low energy losses. As a result, the system works efficiently even in less favorable lighting conditions! In addition, the compact size and the possibility of mounting on the balcony balustrade make the EcoFlow kit with Trina panels a perfect solution for apartments in blocks of apartments - it does not require large space or complicated installation work.

Adjustable mounts for PV panels

EcoFlow mounts for photovoltaic panels are also part of the kit, which, thanks to the ability to adjust the tilt angle from 20° to 75°, allow optimizing the level of solar energy collection. Such a solution allows to adjust the position of the panels to changing conditions, which significantly affects the efficiency of power production. In addition, the mount provides users with installation versatility - you can mount it on a wall, balcony railing or directly on the ground.

Smart Plug smart outlet

The included smart socket makes it easy to manage energy consumption. It monitors power consumption in real time, so the microinverter will be able to allocate the right power to each equipment, and production will not exceed consumption. What's more, combined with a dedicated Smart Plug app, it allows you to remotely control the connected devices. Simply connect your washing machine, refrigerator or lamp to it, for example, and gain the ability to control them remotely! You can also create work schedules. Make your appliances automatically start up at specific times - for example, when you wake up in the morning or come home from work.

Necessary cables

You'll also find the necessary cables for your system included. EcoFlow PowerStream MC4 flat cables (Multi-Contact 4, standard connector for photovoltaic panels) allow you to seamlessly connect your photovoltaic panels to the microinverter located inside - without having to drill holes in the wall. Just run them through the gaps under doors or windows! On the other hand, the 3m extension cables offer more flexibility during installation. With them, you can connect the panels in such a way as to give them the best possible exposure to the sun. The kit also includes AC and PV cables.
