EcoFlow 2000 Wp balcony solar power station with STREAM Ultra X 3.8 kWh battery (4 solar panels)

The EcoFlow 2000 Wp balcony solar power station with the STREAM Ultra X 3.84 kWh battery is the kit with the highest solar power output in this configuration, designed for those who want to generate a high daily yield, store surplus energy and use their own electricity when it is really needed in the home.

The kit includes an EcoFlow STREAM Ultra X battery with a capacity of 3.84 kWh and four NIWA JW-HD108N-R2-500 solar panels from Jolywood, each with a power output of 500 W. The total power of the solar modules is 2000 Wp, making the system well-suited for active daily electricity generation, faster battery charging and increasing the proportion of self-consumption.

The STREAM Ultra X functions as a large home energy buffer. During daylight hours, it stores surplus electricity, which can then be used in the morning, evening or during peak loads. This helps to reduce the amount of energy fed into the grid and allows more of it to be used directly in your own home.

The storage unit is equipped with 4 MPPT trackers and supports a PV input of up to 2000 W, i.e. up to 500 W per channel. This configuration is well suited to four 500 W solar panels and allows for efficient operation with a large solar array.

The kit connects to a 230 V domestic mains supply. The mains AC output is up to 800 W, the battery’s AC output is up to 1200 W, and the bypass output supports connected devices with a power rating of up to 2300 W. This makes the system suitable not only for basic consumption but also for individual household appliances within the storage unit’s capacity.

The total weight of the main components of the kit is approximately 148.0 kg, excluding cables, packaging and mounting hardware. The STREAM Ultra X battery weighs 38.8 kg, and the four solar panels together weigh approximately 109.2 kg. The battery dimensions are 420×294×460 mm, and the dimensions of a single panel are 1960×1134×30 mm.

The actual dimensions depend on the installation layout. If the four panels are placed in a single row without installation gaps, the approximate panel area will be 7840×1134×30 mm. If the panels are arranged in a 2×2 configuration, the approximate panel area will be 3920×2268×30 mm. The total area of the four solar modules is approximately 8.89 m².

The NIWA JW-HD108N-R2-500 solar panels feature a Full Black design, a glass-on-glass construction, N-Type J-TOPCon technology and a bifacial design. Thanks to the bifacial design, the panels can achieve additional power generation from reflected light if installed on a suitable surface.

Control and monitoring are available via the EcoFlow mobile app. The STREAM Ultra X supports Wi-Fi and Bluetooth, and a connection to Wi-Fi and the EcoFlow App is required for the full functionality of the STREAM series. In the app, you can monitor the system status, view the operating history and configure usage scenarios.

The unit has an IP65 rating, an operating temperature range of -20 to +55 °C, battery self-heating for low-temperature charging, and a noise level of less than 30 dB. The battery is rated for 6,000 cycles to 70% capacity, and the STREAM Ultra X comes with a 10-year warranty.

The kit includes a STREAM Ultra X 3.84 kWh battery, 4 NIWA JW-HD108N-R2-500 solar panels (500 W each), 4 pairs of 5+3 m solar extension cables with a total length of 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.
