Weight 23.1±0.5kg Build in Feature Output Overcurrent Protection, Output Overvoltage Protection, Anti-islanding Protection Q&A Are there any electricity billing requirements for grid-connected use of STREAM Ultra? If the requirements are not met, what should I do? Before purchasing or using this product, please confirm whether your household electricity billing supports net metering. If net metering is not supported, you need to use the STREAM system with Shelly Pro 3EM configured for single-phase monitorin. Make sure all STREAM Ultra units are installed on the same phase as the Shelly Pro 3EM (with L2 as an example in the figure) to ensure optimal energy management. After installation is complete, open the Feed-in Control in the app's System Settings. Then go to Energy Delivery Strategy, select Smart Meter Monitoring Mode, and link the Shelly Pro 3EM to begin operation. How can I confirm whether my household electricity billing supports net metering? Please contact the utility company to confirm whether net metering is supported for your house. Is STREAM Ultra waterproof and dustproof? The STREAM Ultra is rated NEMA 4, suitable for indoor/outdoor use. Install in a shaded, ventilated location out of direct sunlight. Can I extend the EcoFlow STREAM Ultra AC Cable? No, not supported. Can the EcoFlow STREAM Ultra AC Cable be plugged into a power strip? This is not recommended, as malfunctioning devices on the power strip could damage the STREAM Ultra. Can I install the STREAM Ultra by myself? The STREAM Ultra can be installed and maintained by users themselves (only available in Utah, USA now).*Please refer to the Power Connection Requirements section under the Installation Preparation chapter in the Installation Guide to choose the installation method that suits your household situation.*Each time you change the installation location, please refer to the above information again. Can the STREAM Microinverter connect to the STREAM Ultra, and what about other (third-party) Microinverters? Yes, and it supports connecting STREAM Ultra to third-party microinverterson the market through the AC outlets (NEMA 5-15). Can the product connect to 5GHz Wi-Fi? Currently, it only supports 2.4GHz Wi-Fi. If there are multiple devices in the STREAM system, will it prioritize using up one device's power before starting to use another's? Not necessarily. It might prioritize using one device's power or discharge multiple devices simultaneously. The system employs an intelligent charging and discharging strategy based on the current power levels of the devices, the power consumption of the appliances, the actual connection setup, and your settings in the app. Thus, the discharging performance of specific devices may vary. Each MPPT of the STREAM Ultra has a maximum power of 500W. Can I connect solar panels with more than 500W to each port? Yes, as long as the solar panel meets the conditions of operating voltage (15-60V) and operating current (≤14A). This can optimize solar utilization during low sunlight conditions. How many STREAM Microinverters can the STREAM Ultra support? Due to regulatory limits, it is recommended to connect no more than one. Can third-party solar panels be used with the STREAM Ultra? As long as the panels meet the input range for the PV port and use the same type of connector, they can be used. Each PV port’s input range is: operating voltage 15-60V, operating current ≤14A. How does the system continue to supply power during a blackout? For safety and compliance reasons, the STREAM system will automatically detect a grid anomaly and stop feeding current into the grid during a power outage. You can then plug in your appliances directly into the AC outlets to use internal battery or solar power. Can the STREAM Ultra be laid flat or inverted? For better heat dissipation and device longevity, it must be placed upright. How can I monitor the power generation and consumption of the STREAM Ultra product in real-time? You can view real-time energy generation statistics on the EcoFlow app. Is it normal for the product to heat up during use? Yes, a temperature rise during use is normal and does not affect the product’s lifespan. The unit has passed rigorous testing and includes overheat protection. For best performance, install it out of direct sunlight with at least 3 cm clearance from walls or objects, and away from flammable materials. Does STREAM Ultra need to be connected to Wi-Fi and the EcoFlow app? STREAM Ultra requires connection to both the EcoFlow app and Wi-Fi to enable full features. Bluetooth or LAN-only access limits functionality such as app automations. What is required to enable energy balancing between multiple STREAM Ultra units? All devices must be connected to the same network and added to the same “Space” within the EcoFlow app. How does the STREAM system work? The system prioritizes solar energy. When solar generation falls short of the power demand, the battery automatically steps in to make up the difference. If there’s still a shortfall, the grid supplies the remaining power.When solar output exceeds consumption, the excess energy is first stored in the battery. Any additional surplus can be exported to the grid, depending on your settings and in compliance with local regulations. Footnote: 1. When using 1 × EcoFlow STREAM Ultra + 1 × EcoFlow STREAM Microinverter together, the system provides a max. 1200W on-grid AC output. When combining 2–6 × EcoFlow STREAM Ultra (with or without 1 × EcoFlow STREAM Microinverter), the system also delivers a max. 1200W on-grid AC output. A single EcoFlow STREAM Ultra (standalone) has a max. 800W On-Grid AC output. 2. Projected power generation values are based on the use of 1 × EcoFlow STREAM Ultra and 1 × EcoFlow STREAM Microinverter under simulated conditions. Calculations assume 5.5 hours of sunlight per day, using the U.S. as an example, factoring in weather variables such as rain throughout the year. 3. The self-consumption rate is calculated using generation estimates from 1 × EcoFlow STREAM Ultra and 1 × EcoFlow STREAM Microinverter, aligned with average annual U.S. household electricity usage. Actual results may vary based on location, climate, and system setup. 4. The estimated savings are based on projected generation from 1 × EcoFlow STREAM Ultra and 1 × EcoFlow STREAM Microinverter, combined with average U.S. electricity rates. Actual savings may differ due to utility pricing, user habits, and environmental conditions. 5. To ensure electricity stability and safety, please familiarize yourself with your local legal requirements for installation, usage, and electrical grid connection of the Product, and consult with local authorities, utilities, and qualified electrical professionals. 6.
