Grounding on a car hauler...

[DiveN4Gold]

I am building a cargo conversion and have ~ 2300W of solar on the roof. Driving all of the systems (both 240 and 120) is an EcoFlow DELTA Pro Ultra. My question is about grounding. Do I need to ground the Delta Pro Ultra to the chassis via the grounding screw on the inverter, or no? The Delta Pro Ultra was the only all-in-one system that fit my needs. I probably should have gotten a separate all-in-one and batteries, but I didn't. I jsut want to make sure that the 340v of panels don't kill me. Thank you in advance.

(not a professional opinion, just logically thinking)

"Grounding" for AC is different from chassis grounding for mobile applications. "Grounding" as it's called is bad naming where it should be "Bonding". Following code requirements for housing applications, you bond neutral and ground at the first disconnect. Perhaps this is what is needed here. Someone with more experience might be able to give a professional opinion.
