Grounding Considerations

Proper grounding is essential for safe operation. EcoFlow offers an AC cable with an equipment grounding conductor/a grounding plug. If the cable has been plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances, the device will be properly grounded. However, if you encounter the following situations, consult a qualified electrician:

• You are unsure whether the product is properly grounded;
• You find that the plug provided with the product does not fit the outlet.

If the installation site does not meet grounding requirements or specific grounding standards mandated by local codes, ask a qualified electrician to use the grounding terminal on this product to establish proper grounding.

Grounding work shall be performed only by a qualified electrician.

Supply Power to Appliances

The device supports supplying power to appliances through the AC outlet on the device or via an existing home circuit, allowing flexible connection of appliances.

Application 1: Appliances Connected to the Device's AC Outlets

Connect the appliance directly to the device's AC outlet. The power supply may come from solar energy, grid power, or the device's battery storage. When at least two devices are connected in parallel, the additional units further enhance the power supply, enabling the system to deliver up to 2300W to connected appliances.

In this application, the device also provides backup power by automatically switching to battery power during a grid outage to keep the connected appliances running.

To Connect an Appliance

1. Plug your appliance into the AC outlet on the device.
2. Press the AC ON/OFF button once to enable the AC outlet.

To Remove an Appliance

1. Power off the connected appliance and disconnect it.
2. Press the AC ON/OFF button once to disable the AC outlet.

The backup power switch time varies depending on solar power efficiency and battery conditions, and may take up to 3 seconds. Do not connect appliances that require seamless power switching, as this device is not designed to function as an uninterruptible power supply (UPS).

The AC outlet remains enabled when grid power is connected. When off-grid and the outlet is not in use for approximately 2 hours, it automatically disables. After 30 minutes of inactivity, the device will automatically shut down to save battery.

Application 2: Appliances Connected to Other Home Outlets

Connect the appliance directly to another wall outlet in your home. When the device is connected to the home circuit (e.g., through an outlet or circuit breaker), it automatically manages power distribution based on the settings in the EcoFlow app. Once another home outlet draws power for an appliance, the device supplies the corresponding output. The maximum power the device (and its cascaded system, if applicable) can support is limited by the available grid-feed power.

In this mode, if there is a grid power outage, the device will not automatically switch to battery power to supply the load. You can manually connect appliances to the device's AC outlets.

3. Press the power button for 2 seconds to turn off each device.
4. Unfasten the screws on both ends of the parallel cable to release the plugs. Then, rotate the plug counterclockwise and remove the cable.
5. Open the EcoFlow app and unbind the devices from your account if necessary.

The parallel connection should only be performed when the main device is disconnected from the Grid. If the grid connection fails, the paralleled units cannot function as a system and will operate separately.

The default protective cap should be kept on any unused terminal. Up to 6 STREAM devices can be installed in a system. Cascaded and distributed configurations can be combined freely within this limit.

Method 2: Multi-Room Distributed Configuration

This setup is only allowed if local electrical regulations permit the device to be plugged directly into a home socket.

This configuration allows STREAM devices to be installed in different rooms, offering flexible placement throughout the home. Each device connects individually to an AC socket on the same power circuit, while still sharing battery resources across the system. Synchronized power management and communication are enabled through the existing home circuit and WLAN, eliminating the need for physical parallel cabling.

To Install a Distributed System

1. Connect the EcoFlow STREAM AC Cable to a STREAM device's Grid Terminal to a home outlet and then tighten the screw on the plug. Tip: Once connected to an active power source, STREAM devices will power on automatically.
2. Connect additional STREAM devices separately in the rooms where you want to assign them.
3. Open the EcoFlow app to bind the STREAM devices to your account. Make sure all devices are connected to the same Wi-Fi network.

To Remove a Distributed System

1. Power off the connected appliances and disconnect them.
2. Disconnect all STREAM devices from the grid and any solar input. If either is connected, powering off the devices will not take effect.
3. Press the power button for 2 seconds to turn off each device.
4. Move or store the devices as needed.
5. Open the EcoFlow app and unbind the devices from your account if necessary.

The default protective cap should be kept on any unused terminal. Up to 6 STREAM devices can be installed in a system. Cascaded and distributed configurations can be combined freely within this limit.

System Scheduling

The STREAM device supports a basic power scheduling scheme. When no smart sensor is integrated, the feed-in power cannot be adjusted in real-time according to household power consumption. Instead, it can only be manually set to a fixed power, or scheduled based on specific periods via the EcoFlow app. Smart sensor integration enhances scheduling capabilities.

Flexible Scheduling with Smart Plug

A smart plug allows you to manage when appliances are powered on or off through the EcoFlow app, offering more flexibility in physical placement. Once integrated into the system, STREAM devices will adjust feed-in power based on the total load of appliances connected to the smart plug, prioritizing their power supply and backup resources.

To Add a Smart Plug

Follow the Smart Plug's user manual to complete the installation. Ensure the plug is connected to the same wireless network as the STREAM system.

To Remove a Smart Plug

1. Power off the connected appliances, then remove the plug from a home outlet.
2. Move or store the smart plug as needed.
3. Open the EcoFlow app and unbind the smart plug from the STREAM system if necessary.
