Gen need ground

[LarryL]

I just put in a Progressive EMSHW-50C in my 5ver with remote display.

When I use my Honda EU3000is do I have to ground the gen In the past

I have not things work fine will the EMS not let power go through because

of no ground and also there is a bypass switch on the remote display but

is it off up or down?

And if the gen is in the the truck bed and needs to be grounded would

I ground it to the truck or 5ver?
