| Balcony photovoltaic with energy storage 1,92kWh EcoFlow STREAM Ultra 1020W. 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 and two Trina Vertex S+ photovoltaic panels of 510W each. The storage combines robust battery capacity (2 kWh), high efficiency and smart energy management to provide energy independence at home. Thanks to its quiet operation, wide temperature range and IP65 rating, it will work well in both indoor and outdoor environments. Robust design and high resistance The EcoFlow energy storage unit has dimensions of 255 × 284 × 458 mm and a weight of 23.1 kg, which, with its capabilities, makes it extremely mobile. 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. Two 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 for positive pressure (such as snow) and 2400 Pa for negative pressure (such as strong wind).
