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.
News item from EcoFlow
Although I like the simplicity of ecosystem I run into problems without a proper instruction book to understand the system fully. I have 2 x ecoflo river2 and like the 1 hour regeneration system. My use is sat radio, charging phones, fan, and testing 12 v devices. Never found it useful to use for emergency EV charge. Be careful and don’t get ahead of yourself. Good for camping and temp power but don’t bank on sustainability or a replacement of grid options.
Will no longer work in America with new digital or smart meter, as they only record with incoming power not outgoing!!! You need utility approval and change mode on meter … You need an inverter with limiter capacity, it has current sensors on both legs of the power line!!!!
Would still be helpful to cut usage. In Pg&E territory you can ask for an analoge meter to be put back on. Not sure bout other power companies. Still might run into issues if it spinnes backwards the entire month. But could definetly get you closer to zero. But i personly am worried. People are very ignorant here. And our home electrical wiring is not nearly as robust as in europe.
Can’t wait until it’s available in Florida!
Did you mention why this doesn’t require utility approval?
I don’t see that anywhere. If you put it in your headline, you might want to at least mention it in the article.
It’s a portable battery so it doesn’t need to be hardwired.
Why limit availability to only a single state on launch if that’s the only reason though?
I think this is brilliant, iam so happy there is something available to get you off the the electric company’s total dependency. Without a lot of red tape to go through
I love the EcoFlow brand and this technology sounds very exciting and promising.
This seems unlikely to work in the USA..
Some red flags to look for..
There’s a grid tied micro inverter involved.. meaning the system can backfeed, meaning utility interconnection would be necessary, which in turn means permitting would still be necessary.. unless you don’t want those back fed credits or unless you want a renegade project. People install non permitted projects, but liability falls on you.
Also not sure if you noticed but this is Plug and Play solar..
They have the solar PV back feeding through the electric lines in the walls of the house.. lot of people wouldn’t figure this out, but if you over feed the PV through the lines in the house you can essentially overheat those wires and cause your house to burn down.. this seems like a really horrible way to make a system to be honest.. the only way to add additional PV would be to have a separate solar PV array hooked into a separate wall outlet.. a bunch of wires coming into the house from different spots.
But you’d also have to confirm that outlet is on a separate circuit, otherwise you’re stacking on the same electric line..
This is very untraditional approach, and not very robust of a a electric option. That’s why typically back feeding is done on the main electrical panel where it can handle much more current.
I feel like EcoFlow takes the same risk with the XSTREAM charging on their larger batteries, like the Delta series. The default charging rate is already high for what you should pull through most residential breakers, and it typically ends up sharing that line with other high amperages devices too.
They aren’t alone obviously, but it’s been one of their major advantages over the years
That sounds great. But it does not take into acount loads. If you have A 20 AMP breaker for the circuit. You have 12 gauge wire in US houses. Rated for 20 AMP. If you plug in an inverter capabale of producing 20 AMP. Even if you where to put a breaker on the Plug & play. You now have the potention of having 40 amps in that circuit. Most of the time it will actully be fine. But when its not. Your house might burn down. The huge diffrence between here and Europe is they would upsize the wire. You can definetly pull more then 20 AMPS on 12 gauge with no issues. But they would propble be using more like 10 Gauge for the same circuit. They also have higher voltage. Which halves the amps for the same watt production. So the small Plug & plays are rarely going to cause an issue.
Would like a sample of product-useful for renters in California. Also pricing and shipping costs.
Thanks! Jean
Can’t wait for it to be available in Oregon!
