FAQ

After plugging in a smartphone, the USB symbol on the EcoFlow DELTA Pro Ultra flashes.

It probably means there is poor contact between the charger and the phone. Try plugging it in again, changing the input port, changing the charging cable, or trying a different phone.

Batteries cannot be charged in low temperatures.

The battery has a self-heating function. At sub-zero temperatures, the battery pack will heat up to above-zero temperatures. However, for improved charging and discharging performance, place the battery indoors. After enabling the battery's self-heating function, the temperature will rise to the optimal level, and each discharge cycle will consume 10% of the electricity.

Incessant battery overheating

The battery cell will show overheating at 60 degrees. It must be stationary in a cool place for at least 2-3 hours before returning to a safe working temperature.

The EcoFlow DELTA Pro Ultra app interface does not have independent AC and DC output data.

Switch to the app's standard mode to see to see an EcoFlow DELTA Pro Ultra single-unit interface.

Can the EcoFlow DELTA Pro Ultra connect to the EcoFlow Smart Home Panel?

No. You can purchase an EcoFlow Smart Home Panel 2 and an EcoFlow Double Voltage Hub - Power Input/Output (DELTA Pro) (connects 2 x EcoFlow DELTA Pro to EcoFlow Smart Home Panel 2) to replace the original EcoFlow Smart Home Panel and connect 2 x EcoFlow DELTA Pro Ultra and 2 x EcoFlow DELTA Pro at the same time to achieve an 21.6kW output.
