Product FAQs

EcoFlow DELTA 3 Max Plus Product FAQs

What's the IP rating of DELTA 3 Max (2048Wh) or DELTA 3 Max Plus (2048Wh)?

IP20 + potting protection

What materials are the batteries for DELTA 3 Max (2048Wh) or DELTA 3 Max Plus (2048Wh) made of?

DELTA 3 Max (2048Wh) and DELTA 3 Max Plus (2048Wh) batteries are LFP batteries.

When DELTA 3 Max Plus (2048Wh) is connected to an extra battery, which one charges first, and which one discharges first?

The charging logic between the main device and the extra battery is that the one with the lower voltage charges first. Once the voltage levels of the main device and the extra battery are the same, they charge simultaneously. During discharging, the one with the higher voltage discharges first. When the voltages become equal, both the main device and the extra battery discharge together.

Do DELTA 3 Max (2048Wh) and DELTA 3 Max Plus (2048Wh) support switching AC power output frequencies? How can I do this?

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.

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.
