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 an EcoFlow DELTA Pro Ultra single-unit interface.
There is a 274 fault code when using a 780W/5700W dryer and charging at 1800W/120V.
A 274 fault is caused by a C20 outlet overcurrent. After a C20 overcurrent, it will switch to INV and discharge normally, as long as you have a split load. At this time, the maximum power should be 7200W. The custom charging mode does not support X-Boost. Once the output load exceeds the set charging power, it will cause the 274 fault. If the user needs to charge and discharge a dryer simultaneously, the C20 must be set to fast charging mode.
