Hello, du to an electricity shortage here, I had to use an inverter to power my refrigerator and lightning into the house. I used my Ioniq EV for this task. The problem is that the voltage kept falling constantly and gradually torought the time I used this setup. In 5 hours of drawing between 90 to 250 watts, the voltage at the 12v battery dropped from 14.2v to a low 11.7v. The inverter was reading at its lowest 11.1v near the automatic low battery cutoff. The car was always ON and everything inside the car OFF. So I was wondering how much power the Ioniq DC to DC charger is able to produce. Thanks.
