The EcoFlow 800W PowerStream Micro Inverter is designed to be used in conjunction with the EcoFlow PowerStream Solar System - the first balcony solar power system with a portable power station that allows you to use solar energy day and night to reduce energy bills. Designed to work with all EcoFlow Portable Power Stations, this system stores all excess energy in your portable power station during the daytime and gives it back to you whenever you need it for convenient, sustainable and environmentally-friendly power. With up to 1039kWh feeding into your home per year, you have the potential to save hundreds of pounds.

You can use this solar system with the EcoFlow Smart Plug and EcoFlow app for real-time energy usage monitoring and power optimisation. Smart Plugs monitor your appliances' energy consumption in real time, so the microinverter can allocate just the right amount of electricity to each appliance and the surplus to a portable power station. During peak hours, it prioritises home use and most of the energy gets stored in off-peak times.

What's in the box: EcoFlow PowerStream Micro Inverter, BKW-AC Cable & BKW-Solar Cable.

*Important: EcoFlow BKW-Battery Cable is needed when connecting a PowerStream Microinverter with an EcoFlow Portable Power Station. On all RIVER Series Portable Power Stations, DELTA mini and DELTA (1300), the car charging port is for streaming output into the microinverter, while the solar input port is for solar recharge. The car charging port is the only way for these portable power stations to connect with the microinverter. Due to the limitation of the car charging port, these power stations are subject to an output limit of 100W.
