EcoFlow 1940 Wp balcony solar power station with STREAM Ultra X 3.8 kWh battery (4 solar panels)

The EcoFlow 1940 Wp balcony solar power station with STREAM Ultra X 3.84 kWh is a powerful kit for a balcony, terrace or home solar system where not only high daytime generation is required, but also a large energy reserve for later use.

The kit consists of an EcoFlow STREAM Ultra X battery with a capacity of 3.84 kWh and four AIKO Neostar Pro 3S+ solar panels, each rated at 485 W. The total peak power of the solar modules is 1940 Wp, so the system is well suited to scenarios where you need to charge the battery faster and make more efficient use of daylight hours throughout the day.

The STREAM Ultra X has 4 MPPT trackers and supports a solar input of up to 2000 W. This is well suited to a four-panel configuration, as each PV channel is rated for up to 500 W. The maximum PV input voltage is 60 V DC, and each AIKO-A485-MCE54Db panel has an open-circuit voltage of 41.00 V and a maximum power point operating voltage of 34.60 V.

The system connects to the 230 V domestic mains supply. The mains AC output is up to 800 W, the battery AC output is up to 1200 W, and the bypass output supports loads of up to 2300 W. This allows the stored solar energy to be used not only for basic consumption but also for more energy-intensive domestic scenarios within the system’s capabilities.

The total weight of the main components of the kit is approximately 135.6 kg, excluding cables, packaging and mounting hardware. The STREAM Ultra X battery weighs 38.8 kg, whilst the four solar panels together weigh approximately 96.8 kg. The battery measures 420×294×460 mm, and each panel measures 1762×1134×30 mm.

As the kit consists of a separate storage unit and four solar panels, the overall dimensions depend on the installation method. If the panels are placed in a single row without mounting gaps, the approximate panel area will be 7048×1134×30 mm. When arranged in a 2×2 configuration, the approximate panel area will be 3524×2268×30 mm. The total area of the four solar modules is approximately 7.99 m².

Control and monitoring are available via the EcoFlow mobile app. The STREAM Ultra X supports Wi-Fi and Bluetooth, so users can monitor the system’s operation, view the battery’s status and adjust settings via the EcoFlow App.

The battery has an IP65 protection rating, an operating temperature range of -20 to +55 °C, a battery self-heating function for low-temperature charging, and a noise level of less than 30 dB. This makes the system practical for everyday use, where quiet operation, protection from the elements, and stable performance throughout the seasons are important.

AIKO Neostar Pro 3S+ solar panels feature a full-black design, N-Type ABC cells, double-glazed glass, a black aluminium frame, original MC4 connectors and an IP68 junction box. The panels come with a 30-year product warranty and a 30-year performance warranty, whilst the STREAM Ultra X battery has a 10-year warranty.

The kit includes a STREAM Ultra X 3.84 kWh battery, 4 AIKO Neostar Pro 3S+ solar panels (485 W each), 4 pairs of 5+3 m solar extension cables (total length 8 m), and a 1.5 m AC cable for connection to a 230 V socket. If required, the system can be supplemented with longer solar cables or flat cables for convenient routing through window or door frames.
