Apparently this Youtuber damaged her older generation Land Cruiser by dual sourcing a Jackery from a solar panel and the vehicle inverter. New products like the Ecoflow Delta 3 advertise the ability to leverage multiple simultaneous inputs (AC, DC, Solar panels etc.) to increase charging speed and diversify power sources. So I thought this might be interesting in case anybody has thoughts on what happened and how to avoid similar issues on new Land Cruiser 250s.
I fried my car with a Jackery with a portable battery solar generator
I didn't watch the video, but there is little reason to bother solar charging with a 2400W inverter in the vehicle. There was more reason to possibly use solar with the older Toyota inverters at 400W
