The EcoFlow Stream Ultra X is a hybrid home storage system with a capacity of no less than 3.84 kWh. It allows you to store and use your own solar power whenever you need it - without any complicated installation or technical knowledge. You simply plug the storage system into the socket and control everything conveniently via the EcoFlow app. During the day, you can charge the battery with electricity from your solar panels (or from the grid) and simply use the electricity yourself in the evening or in the event of a power cut. This saves you energy costs and makes you less dependent on the grid. Increase capacity even further. An EcoFlow Stream Ultra X home battery already has an impressive storage capacity of 3.84 kWh. However, this can be increased even further by connecting up to 6 Ultra X batteries together. In total, you can expand the system to a capacity of no less than 23 kWh. Returning and charging. You can supply connected devices with up to 1,200 W via the integrated socket, plus 1,100 W forward current, i.e. 2,300 W in total. In addition, you can feed up to 1,200 W back into the mains if the Stream is connected to its own circuit. In a shared circuit, you can feed back a maximum of 600 W in the Netherlands and 800 W in Belgium. The Stream Ultra X can be charged with 1,200 W from the grid or directly from your solar panels with a maximum of 2,000 W (4 solar panels of 500 W each). Do you already have an inverter for your solar modules? Then the EcoFlow Stream AC Pro may be the better choice.
