HomeEcoFlow Launches Plug-In Solar Power Systems for US Households
The United States is now introducing EcoFlow's DIY balcony solar system, which I previously reviewed in Europe. EcoFlow states that its Stream Series will be the first plug-and-play solar products available domestically, enabling homeowners and renters to reduce their energy bills effortlessly while offering some backup power during grid outages.
However, these systems are initially launching only in Utah, where regulations now permit balcony solar units that connect directly to standard 120V outlets—eliminating the need for complex and expensive utility interconnection agreements. EcoFlow clarifies that there is no requirement to wait for federal certification under the National Electrical Code or a specific product safety standard from Underwriters Laboratories, as some have speculated. Balcony solar systems are already widely used across Europe, with millions of units safely installed.

The plug-and-play Stream series uses a microinverter to convert solar energy into grid-compatible electricity for home use. Some energy can also be stored in EcoFlow’s batteries for emergencies or used later to help reduce peak electricity rates from utility providers.
EcoFlow’s Stream Ultra combines a built-in grid-tied microinverter with a sizable 1.92kWh LFP battery. It can be installed indoors or outdoors, thanks to its self-heating feature that allows operation in temperatures as low as -20°C (-4°F), along with an IP65 rating for dust and rain resistance. Storage capacity can be expanded to 11.52kWh by adding extra battery-only Ultra units. The Stream Microinverter is also sold separately for those who already own a compatible EcoFlow power station.

1/3The Stream Microinverter converting solar energy into grid-ready electricity. Image: EcoFlowThe system supports up to 2000W of solar input from panels installed on a roof, placed on the ground, or mounted on a balcony. When connected to a dedicated 15A circuit, the microinverter can feed up to 1200W back into the home, reducing the electricity drawn from the grid.
EcoFlow’s Stream devices work with the new Oasis energy management platform, allowing users to monitor and optimize their system remotely through the EcoFlow app.
Pricing includes preorder discounts available until July 31st. The Stream Microinverter starts at $299 (regularly $599), the Stream Ultra with Microinverter is $1,459 ($2,399 list), and the battery-only Stream Ultra is $1,199 ($1,899 list).
