EcoFlow introduces STREAM Series, a plug-and-play solar + storage system for the U.S. residential market. The system can be purchased with or without a battery. The battery version is known as STREAM Ultra.
STREAM will be available in Utah at launch, with plans to roll out to other states in the future. Utah’s rising electricity rates, strong solar potential and growing percentage of multi-family dwellings make STREAM Series a great option for residents seeking a plug-and-play, DIY solar solution with no installation and no utility approval needed.
“By launching Stream Series in Utah, we’re taking the first step in making renewable energy simple and accessible for people in the U.S. who have not been able to enjoy the benefits of residential solar,” said Brian Essenmacher, head of North American business development at EcoFlow.
“We’ve successfully launched this solution across Europe over the past two years with more than 120,000 units sold,” Essenmahcer continued. “We’re now applying our global experience to bring flexible solar options to Americans beyond just single-family homes. Plug-and-play home solar systems allow people to save on electric bills while avoiding the high costs, permitting and months-long installation timelines of traditional systems.”
The EcoFlow STREAM series includes two key products: STREAM Ultra and STREAM Microinverter. The STREAM Ultra is a 1.92-kWh solar battery with a built-in grid-tied microinverter. The battery can collect 2 kW of solar input, with up to 1.2 kW fed directly into the home via the microinverter, with excess energy stored in the battery.
For homes without energy storage needs, the optional standalone STREAM Microinverter converts solar energy directly into the home via a standard AC wall outlet up to 1.2 kW output.
This flexible system allows residents to position solar panels on balconies, patios, backyards and other outdoor spaces.
When multiple Ultra batteries are connected, the modular setup can expand from 1.92 kWh to 11.52 kWh and allows flexible battery placement. Powered by an AI-driven solar network, multiple batteries can work in sync — no matter where they’re located — to extend runtime, minimize grid reliance and eliminate solar waste. With its plug-and-play setup and intelligent energy flow management, households move closer to energy independence and zero electricity bills.
STREAM Ultra’s LFP battery retains 70% capacity even after 6,000 cycles and operates reliably in extreme temperatures down to -14°F. With a NEMA 4 rating for the Ultra battery and NEMA 6 for the microinverter, the system is built to handle both indoor and outdoor conditions. Built-in safety mechanisms continuously monitor energy loads in real time, automatically adjusting power to stay within the 1.2-kW limit and prevent tripping household circuits.
The STREAM Series is compatible with EcoFlow OASIS, an AI-powered energy management platform available through the EcoFlow app, designed to maximize home energy storage, prepare for weather-related power outages and reduce electric bills.
EcoFlow’s STREAM Series is now available for pre-order, with official availability launching on July 14. More information on pricing can be found here.
