Yes, charging times can be set.
EcoFlow DELTA Pro Ultra is not compatible with third-party inverters.
The fastest charging power for one battery is 6200W. It takes about 92 minutes to charge one battery from 0% to 100%, but if stacked on two or more batteries, the maximum charging power can reach 8800W. It takes about 1 hour and 56 minutes to charge two batteries from 0% to 100%.
No. The EcoFlow DELTA Pro Ultra Battery needs to be connected to an EcoFlow DELTA Pro Ultra Inverter to charge. EcoFlow DELTA Pro Ultra is not compatible with third-party inverters.
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.
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.
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.
Switch to the app's standard mode to see an EcoFlow DELTA Pro Ultra single-unit interface.
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.
