On October 17, 2026, heise online published a test report on the Bluetti Balco 260 balcony power plant storage system. The test showed that the main unit has a built-in 2.56 kWh LiFePO4 battery; with the BC260 expansion battery, the total capacity is 5.12 kWh, and up to five expansion batteries can be connected for a total of 15.36 kWh. It is equipped with four independent MPPT inputs that together can accept up to 2400 W of solar power, and it supports AC surplus charging with the Shelly Pro 3EM; the price starts at 649 euros. In the test, discharge efficiency at 800 W was good, but the usable AC energy was somewhat lower during constant-power discharge at 200 W, and standby loss was about 20 W. There are currently no further developments.
