The STREAM Ultra is rated NEMA 4, suitable for indoor/outdoor use. Install in a shaded, ventilated location out of direct sunlight.

Is STREAM Ultra waterproof and dustproof?

Can I extend the EcoFlow STREAM Ultra AC Cable?

This is not recommended, as malfunctioning devices on the power strip could damage the STREAM Ultra.

Can the EcoFlow STREAM Ultra AC Cable be plugged into a power strip?

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 I install the STREAM Ultra by myself?

Yes, and it supports connecting STREAM Ultra to third-party microinverterson the market
through the AC outlets (NEMA 5-15).

Can the STREAM Microinverter connect to the STREAM Ultra, and what about other (third-party) Microinverters?

Currently, it only supports 2.4GHz Wi-Fi.

Can the product connect to 5GHz Wi-Fi?

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.

If there are multiple devices in the STREAM system, will it prioritize using up one device's power before starting to use another's?

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.

Each MPPT of the STREAM Ultra has a maximum power of 500W. Can I connect solar panels with more than 500W to each port?

Due to regulatory limits, it is recommended to connect no more than one.

How many STREAM Microinverters can the STREAM Ultra support?

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.

Can third-party solar panels be used with the STREAM Ultra?

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.

How does the system continue to supply power during a blackout?

For better heat dissipation and device longevity, it must be placed upright.

Can the STREAM Ultra be laid flat or inverted?

You can view real-time energy generation statistics on the EcoFlow app.

How can I monitor the power generation and consumption of the STREAM Ultra product in real-time? 

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.

Is it normal for the product to heat up during use?

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.

Does STREAM Ultra need to be connected to Wi-Fi and the EcoFlow app?

All devices must be connected to the same network and added to the same “Space” within the EcoFlow app

What is required to enable energy balancing between multiple STREAM Ultra units?

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.
