Balcony photovoltaic with energy storage 1.92kWh EcoFlow STREAM AC Pro 1020W.

Balcony photovoltaic with energy storage 1,92kWh EcoFlow STREAM AC Pro 1020W.

The EcoFlow STREAM Easy 1020W balcony photovoltaic is an advanced photovoltaic kit that includes a Stream microinverter with PV and AC cables, EcoFlow STREAM AC Pro 800W energy storage and two Trina Vertex S+ photovoltaic panels of 510W each. With this combination you get a professional photovoltaic system in your home, which is an extremely ecological, convenient and precise solution. The set will be great for on-grid systems (a system connected to the electricity grid), and thanks to the connection with Wi-Fi and Bluetooth, you can have full control over the device from the app. The microinverter is part of the EcoFlow STREAM Plug & Play Solar system – a solution that combines simple installation, smart energy management and bill savings without the need to call an electrician.

Better adaptation to operating conditions

The EcoFlow Stream microinverter features two independent MPPT (Maximum Power Point Tracking, used to track the maximum power point) paths – each with an input power of up to 600 watts. This allows the device to better handle situations where panels are 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 inverter 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 from 16 to 60 V DC allows it to work with a wide range of photovoltaic 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. The AI-based assistant works 24/7 to help optimize power consumption. The app also includes features such as Savings Calendar to help better save energy and remote control of connected devices. It’s worth knowing that 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 (a technology that allows automatic recognition and configuration of devices after they are connected to the computer, without the need for manual intervention by the user in the hardware settings), the device can be easily installed by yourself, even in rented apartments – without any permanent interference with the structure of the building.

Thoughtful design

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 will successfully mount it outdoors. With a noise level of less than 20 dB, the device remains virtually inaudible. With dimensions of 252 x 180 x 35 mm and a weight of 3.2 kg, it is easy to find a suitable mounting location for it – even where space is limited.

Two Trina photovoltaic panels to complete the set

The Trina Vertex S+ TSM-510NEG18R.28 photovoltaic panel is a state-of-the-art solar module based on N-type monocrystalline cells with i-TOPCon (Tunnel Oxide Passivated Contact) technology. It offers an output power of up to 510 W and an efficiency of up to 22.9%. The double-glass design increases durability and weather resistance. With a length of no more than 2 meters and a lightweight but durable design, the panel will work well on both commercial and industrial roofs.

Stable performance for decades

The panel has a very low temperature coefficient (-0.29%/°C), which translates into better performance in hot weather. A maximum power degradation of 1% is predicted in the first year of operation, and 0.4% per year in subsequent years. This means that after 30 years, the module retains at least 87.4% of its original power output. The dual-glass design (two sheets of glass with a thickness of 1.6 mm) provides high mechanical resistance – up to 5400 Pa under positive pressure (such as snow) and 2400 Pa under negative pressure (such as strong wind).

Reliable energy storage

EcoFlow STREAM AC Pro is a compact energy storage designed with the STREAM microinverter in mind, which has an inverter and 2 classic 230V AC outlets. This allows it to power household appliances both day and night. It is equipped with a battery with a capacity of 1.92 kWh, which makes it possible to power various home appliances – from routers and computers to refrigerators and lighting. The battery is distinguished by its high durability: it retains 70% of its capacity even after 6,000 charging cycles. Thanks to the self-heating function, the device can charge even in cold conditions – the mechanism automatically activates at 5°C or lower.

On-grid operation and emergency power supply

The storage unit can return energy to the grid with a maximum output of 800 watts (AC Grid-Tied – refers to a photovoltaic system that is connected to the electricity grid), supporting the current consumption at home. When you need energy immediately, the STREAM AC Pro can power appliances with up to 1,200 watts directly from the battery. If it discharges, the system automatically switches to bypass mode, allowing you to power appliances directly from the grid – with up to 2,300 watts (10 amps). Such an arrangement guarantees stable operation of the system even at higher power demand or when operating several devices simultaneously.

Simple operation and thoughtful design

The STREAM AC Pro’s housing meets the IP65 standard – it is resistant to dust and splashes, so the device can also be used outdoors without worry. The operating temperature range is from -20°C to 55°C, and the noise level is kept below 30 dB. The housing, which measures 255 × 254 × 458 mm and weighs 21.5 kg, makes it easy to install in various locations. With Wi-Fi and Bluetooth connectivity, the device can be managed from the EcoFlow app. You have access to energy consumption data, can configure charging schedules, remotely turn the devices on and off, and use AI-based smart features – available in part in the premium version.
