@LAD_Systems Hello Luc, I think I may have provided a comment on the Victron energy FB group on this. Please see the post… Multiplus-II 2x120V tripping GFCI
Happy to answer any questions if you would like to discuss further. This is a reasonably common problem in the marine world and the solution is simple enough in concept. A plausible explanation is available for GFCI tripping in many cases.
In many cases intermittent tripping occurs with no fault. It is just plain old fashioned engineering that can be resolved if the problem is understood and once understood it will be crystal clear.
