FAQ

Output Overload Error

AC output overload: the AC icon will appear on the screen, and the ""Overload"" icon will flash: 1. Check whether the connected device's power meets the unit's power range. Connect a device with a wattage of 1400W-2200W to confirm that X-Boost is turned on in the app. If it's already turned on, connect to the app again. 2. In EPS mode, DELTA supports a maximum of 1400W. Confirm whether the electrical equipment is within this range. 3. The power of the electrical equipment is too large, causing it to fail to operate. DC output overload: the ""USB"" and ""Overload"" icons will flash together on the screen: 1. The output of the DC/car charger is overloaded. Check that the rated current of the device is under 8A. If the current is too high, it will cause overload, and the car charger may overheat. 2. The output of the DC-USB-Type C is overloaded. Confirm whether the electrical equipment is within the current limit of the outlet.

Short-term Power Jump When Charging and Discharging

Perform the SoC calibration 3 times. If the problem still occurs, take a video showing the fault and contact the EcoFlow Customer Service team.

DELTA Shut Down Unexpectedly

1. The battery power has run out 2. When AC and DC power is off, and there is no input or output power for 30 min, the device will automatically shut down.

Device does not boot

1. Check if it is caused by an insufficient battery. If it is, charge and turn it on again. If the charging fails, please follow the instructions on charging failures. 2. If there is no response after you short press or long press (3 seconds) the Main Power Button, please contact EcoFlow Customer Service.

DELTA Won't Charge From the Car Charger

1. Confirm that the 12V car charger has a standard voltage and power output. 2. Use another car charging cable to see whether the problem is with the standard car charging cable. Alternatively, use a solar panel to charge DELTA. If the solar panel works, the problem is with the car charger to XT60 cable. If the solar panel does not charge either, contact support.eu@ecoflow.com
