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 2400W-3000W 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 Max supports a maximum of 2200W. 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.
Perform three times SoC calibration by doing three times complete charges and discharges. If the problem still occurs, take a video showing the fault and contact the EcoFlow Customer Service team.
DELTA Max can be charged using any solar panels with the same solar connectors and within an input range of 800W 11-100V DC 13A.
Yes, DELTA Max supports charging and discharging while charging from vehicles, solar panels, etc. However, when the unit's battery is low or about to run out, it is best not to use it while connecting to DC charging (solar/vehicle charging). If the input is less than or equal to the output power, the device will continue to consume power, which may result in power loss and eventually damage the battery.
In addition to charging from the grid, car, and solar, other sources such as generators and inverters can also be used if they output 220–240V (50Hz/60Hz) of sine wave AC power. When charging DELTA Max, the AC input power needs to be greater than 2400W to enable X-Stream function.
