EcoFlow STREAM Easy balcony photovoltaics
The EcoFlow STREAM Easy kit includes a STREAM microinverter, two Trina 400 Watt photovoltaic panels and the necessary cables, including PV (Photovoltaic, photovoltaic) and AC (Alternating Current, alternating current). It allows you to easily start the adventure of balcony photovoltaics – it is very easy to install and configure. With it, you can power selected 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 up to 1,200 watts from PV 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
The set of 2 photovoltaic panels, each 400W, 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.
Intuitive operation via app
With 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, which means full protection from 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.
