Photovoltaics with energy storage 3.84kWh EcoFlow STREAM Ultra 2K 2040W.

EcoFlow balcony photovoltaics is an advanced kit that will help you create a precise, efficient and eco-friendly photovoltaic system for your home. The kit includes a 1.92kWh EcoFlow STREAM Ultra 1020W energy storage, an EcoFlow STREAM AC Pro 800W energy storage and four Trina Vertex S+ photovoltaic panels of 510W each.

Robust design and high resistance

The EcoFlow energy storage has dimensions of 255 × 284 × 458 mm and a weight of 23.1 kg, which, with its capabilities, makes it extremely portable. The IP65-rated enclosure used provides full dustproof and waterproof protection, allowing safe use both indoors and outdoors. Overvoltage category DC II, AC III guarantee safe operation even in harsh conditions.

Long-life battery

The EcoFlow Stream Ultra uses an LFP – LiFePO₄ (lithium-iron-phosphate) battery with a capacity of 2 kWh and a nominal voltage of 19.2 V. It is designed for long life – offering more than 6,000 duty cycles, which translates into years of reliable use. Thanks to natural fanless cooling, the unit operates quietly and trouble-free.

Efficient charging system with 4 MPPT

Stream Ultra supports four independent MPPT (Maximum Power Point Tracking) inputs to maximize the use of energy from photovoltaic sources. Each channel supports up to 500 watts, for a total maximum input power of 2,000 watts (60V/14A). The MPPT voltage range is 15-60V, and the maximum short-circuit current is 20A, ensuring compatibility with a wide range of solar panels.

Energy independence and various output modes

With an AC input of 230 V/50 Hz, Stream Ultra generates a rated power of up to 800 W, with a max. output current of 3.48 A. The max. input power is 2,300 W, and the power factor is adjustable from 1 to 0.8. For AC output, the power supply to devices is at a continuous power of 1,200 W (1,200 VA), with a max. current of 5.22 A and an input power of 800 W. In Bypass Mode, the maximum output current is 10 A, ensuring reliability even with higher loads. On the other hand, for applications requiring more power, the system offers Parallel Connection Mode with up to 2,300 W. This arrangement provides greater flexibility and allows the solution to be scaled for more extensive installations.

Performance in all conditions

The EcoFlow Stream Ultra operates seamlessly in temperatures from -20°C to 55°C, with a humidity range of 5%-95%. It can be safely stored at temperatures from -20°C to 55°C, and its design allows it to operate at altitudes up to 4,000 meters above sea level, making it an ideal choice for applications in harsh locations – from high mountainous terrain to hot deserts.

Smart management and connectivity

The device offers Bluetooth and WLAN connectivity, and full control and management are possible from the dedicated EcoFlow app. This gives the user access to real-time data and the ability to remotely monitor and optimize system performance.

Four Trina photovoltaic panels to complete the kit

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.

Additional EcoFlow STREAM cable

An EcoFlow STREAM cable is also included, which allows you to connect two STREAM series batteries securely and quickly, allowing you to expand your energy storage system. With a length of 55 cm, it provides installation flexibility and stable operation of the entire home installation.
