EcoFlow 1455 Wp balcony solar power station with STREAM Ultra 1.9 kWh battery (3 solar panels)

The EcoFlow 1455 Wp balcony solar power station with STREAM Ultra 1.92 kWh is a high-performance kit for those who want to generate more solar energy than a standard two-panel system, whilst maintaining a compact design, simple installation and convenient everyday use.

The kit combines the EcoFlow STREAM Ultra battery with a capacity of 1.92 kWh and three high-efficiency AIKO Neostar Pro 3S+ solar panels , each rated at 485 W. The total peak power of the solar modules is 1455 Wp, so the system charges faster during the day and makes better use of short sunny spells.

The STREAM Ultra battery stores surplus solar energy so it can be used later — in the evening, at night, or during times when household consumption is higher. This helps increase the proportion of self-consumption, reduce dependence on the grid, and make the balcony power station more efficient in real-life domestic conditions.

The EcoFlow STREAM Ultra has 4 MPPT trackers and supports a total solar panel input power of up to 2000 W. This configuration is particularly useful for a three-panel setup, as it allows for more flexible module connections and better performance under varying light conditions or partial shading.

The system is designed for connection to a 230 V domestic mains supply. The mains AC output is up to 800 W, whilst the device’s own AC output is up to 1200 W. A bypass output is also provided, supporting a maximum device power of up to 2300 W, which expands the range of applications for the home battery.

The AIKO Neostar Pro 3S+ solar panels feature a modern full-black design and are built using N-Type ABC cells. They offer high efficiency, double-glazed panels, a black aluminium frame, original MC4 connectors and an IP68-rated junction box. As a result, the kit looks neat when installed in the open and is suitable for long-term use.

The STREAM Ultra has an IP65 rating, operates in a temperature range of -20 to +55 °C, supports Wi-Fi and Bluetooth, and has an operating noise level of less than 30 dB. This makes the system convenient for use in a flat, a private house, on a terrace, a balcony or in other locations where quiet operation, compactness and a stable power supply are important.

The kit includes the STREAM Ultra storage unit, three 485 W AIKO Neostar Pro 3S+ solar panels, three 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 special flat cables for convenient routing through a window or door.
