Positive x Earth voltage low on test

Victron phoenix 12/800 inverter installed on a steel Hull boat

When I test across live and negative I get 220v. When I test live to earth I'm getting 140v and when a load is applied I'm getting 80v.


I have replace the inverter and get the same issue. I have run a negative cable to the Hull and the problem persists. The appliance I want to run requires a good earth to run properly.


Any ideas. Help much appreciated.

These models are shipped with the AC output isolated from the chassis.
You need to follow the instructions in the manual, see Appendix A on page 12 of the manual linked below:
