According to the manufacturer, the EcoFlow Delta 3 Plus has a nominal capacity of 1024 Wh. 0.7 kWh is actually a little too little for a Delta 3 Plus. According to my research, the usable capacity after deduction of conversion losses and self-consumption is normally around 800-850 Wh. There may be various reasons why the value is lower:
Calibration: The battery management system often has to stabilise first. Charge the device fully once to 100 % and then discharge it completely until it switches off.
Settings: Check in the EcoFlow app whether a "discharge limit" (e.g. 10 % or 20 %) is set that artificially limits the capacity.
If the value is still only 700 Wh after calibration, there may be a technical defect. In this case, please contact us via the Galaxus Assistant:
