This is my 'go to' source for Tesla electronics: He correctly points out the 2018 board has no vehicle-to-grid electronics. The Cybertruck will come with several kW of AC power for contractor equipment. Initially, a standalone, AC power source it may morph into vehicle-to-grid. Today, battery-to-grid is found in the Tesla PowerWall. Bob Wilson
Thanks for that, gives a pretty clear and detailed explanation as to the functions/components and pretty much closes the door on the VTG capability. 2400 watts is pretty good for the DC to DC converter (similar to Kona EV), if a small load is needed during an outage seems like it should handle it through the 12V accessory socket (providing) Tesla has included one of those.
