I fixed the E2 open ground issue with a plug wired with the ground and neutral together.
NOW I have code E1 reverse polarity
I’m thinking you bonded ground and hot, not ground and neutral. Did you connect ground to the wider blade of the plug?
Wouldn't that trip the breaker?
Yes ground to silver wider blade
It would be nice to use the EMS but it's probably not best suited for generator use.
Bonding ground to the hot would not trip a breaker unless there is a (significant) ground/neutral fault somewhere else in the wiring, causing a short circuit.
On the generator itself, the whole output is floating (not bonded to anything), so neutral and ground are electrically interchangeable; it's just a question of which is wired to which blade of the socket.
If the EMS is saying reversed polarity, it means that it sees ground as at the same voltage as hot. This would mean either the bond is between the hot line and the ground, or the hot and neutral are getting switched around somewhere between the plug and the EMS (because something is miswired). Either way, whatever the problem is should be fixed.
