FAQ

Will DELTA 3 Max (2048Wh) or DELTA 3 Max Plus (2048Wh) automatically power on when there is grid or solar charging input while the device is off?

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.

Does the device support Bypass Mode output?

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.

What are the warranty policies for DELTA 3 Max (2048Wh) or DELTA 3 Max Plus (2048Wh)?

The device has a 3-year basic warranty, which can be extended by 2 years if you register on the app.

How do I enable the X-Boost feature?

This feature is enabled by default. It can be enabled or disabled in the EcoFlow app.

When using instruments to measure the AC power output, why are the L and N measurements reversed?

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.
