The EcoFlow Stream Ultra is a compact, integrated solar hybrid system that combines a 1.92 kWh battery and a built-in micro-inverter (1200 W continuous/2300 W peak power) in a single, IP65-certified housing. This allows for DIY installation without separate inverters. The four MPPT inputs accept up to 2000 W of PV power (4 x 500 W) as well as an additional 800 W through the inverter, enabling the system to generate up to 2218 kWh annually, covering more than 70 percent of a typical household's needs, and allowing charging at low temperatures down to -20 degrees Celsius. Multiple units can be connected in series or parallel (up to 11.52 kWh storage and 12 kW PV), with Wi-Fi/Bluetooth for seamless setup and expansion via the EcoFlow app. Intelligent, AI-driven load management and AI-TOU optimization of time-of-use rates automatically allocate solar power and schedule charging cycles to minimize grid electricity costs, while real-time monitoring of generation, storage, and consumption ensures an efficient, scalable, and sustainable energy supply for the home.
