- Product Introduction
Neither the equipment nor the SG3000/4000 supports Bluetooth auto-start/stop functionality. Operation is only possible via AC connection and manual control.
The DELTA 3 Ultra (3072Wh) main unit weighs approximately 32.7kg The DELTA 3 Ultra Plus (3072Wh) main unit weighs approximately 33.7kg
DELTA 3 Ultra (3072Wh) and DELTA 3 Ultra Plus (3072Wh) batteries are LFP batteries.
When DELTA 3 Ultra Plus (3072Wh) is connected to an extra battery, which one charges first, and which one discharges first?
With the AC switch turned on, press and hold the AC switch button for 10 seconds to change the AC output frequency for actual use.
Yes, the device will automatically turn on when charging, so you don't need to worry about the device failing to restart when the power comes back on after a blackout. You can also enable the Port Memory feature in Settings. When the device shuts down due to a depleted battery, it will restore the output port status once charging starts or when the battery level rises above the set backup reserve level.
The device will automatically power on while charging. Charging while powered off is not supported.
Support. 1. Make sure the device (e.g., NAS device, PC, or laptop) supports UPS functionality. 2. Use a data cable to connect the USB-C-140W output port of the portable power station to the USB port of the device (supports USB 2.0 protocol). 3. After the connection is successful, go to the settings page for the device (e.g., NAS) and adjust the relevant settings.
Yes, the switching time between DELTA 3 Ultra Plus (3072Wh) and DELTA 3 Ultra Plus (3072Wh) is <10ms for the UPS.

The device has a 3-year basic warranty, which can be extended by 2 years if you register on the app. (JP: 5-year basic warranty)
When within 1.64 feet of the device, the noise generated is less than 25 dB during 600W consumption and less than 40 dB during 1800W consumption. 30 dB is about the same volume as quiet whispering, or the environmental noise level of a quiet library or office. Most people find 30 dB to be a comfortable level of background noise.
The portable power station is a floating-ground system, meaning that this type of detection equipment is likely to be ineffective. The detection equipment is designed to detect grounded output from grid power. The voltage difference between neutral and ground in the grid is very small, which is why there is a distinction between positive and reverse wiring. The device's AC output is generated by boosting the internal battery voltage through an inverter. Since there is no reference ground, testers may indicate reversed wiring. Furthermore, in the portable power station, both L and N are energized. When operating in inverter-only mode, the two wires can be regarded as equivalent, so the concept of reversed wiring does not apply. Think of it like this: AC voltage follows a sine wave pattern and its direction changes. As a result, the electric potential of L and N change relative to each other. On a microscopic timescale, current flows from high potential to low potential. However, since AC operates at 50 Hz, with 50 direction change cycles per second, the frequency is too high to distinguish. On a macroscopic level, the two wires appear the same during inversion. Many instruments will show the same peak voltage for both wires, so they can be regarded as equivalent with no distinction.
1. Long-press the power supply button for at least 3 seconds to check whether the display turns on. 2. Connect an input to charge the device and check whether there is input power. If there is no response after 10 minutes, contact the after-sales team for assistance.
Yes, Bypass Mode output is supported, and it is enabled by default. It can also be disabled in the app. If the grid power is unstable and may cause improper functioning or damage to appliances, you can enable this setting in the EcoFlow app for appliances that require high-quality power output. For example, this mode allows you to use only the AC output power from the portable power station for speakers.
This feature is enabled by default. It can be enabled or disabled in the EcoFlow app.
For stability reasons, we do not recommend using the device to power critical medical devices such as ventilators.

It cannot be taken on an airplane. For information on whether it can be taken on high-speed trains or cruise ships, please consult the corresponding department or call the customer service number.
Yes, the AC output and the internal system of the device are grounded. If the device's AC input is connected to the grid, it will share the same ground as the grid power.
