It's also possible the PE2 occurred when replugging. Just happened to me because of a worn plug which will be replaced.
So I did retrieve my EMS remote display from our trailer this morning and duplicated your test using my own EU2000i as source power because it has a floating neutral output that is interpreted by the Progressive EMS as an "open ground", a condition that can be corrected with the use of a G-N bonding plug. Indeed, you were absolutely correct - once power is removed completely the EMS loses any "previous error" code, so it's therefore not held in any kind of EPROM memory. That also means that because I did have a PE2 code when camping it had to have occurred
after campsite power was restored, not
before. However, I'm still a bit perplexed at just
when the EMS loses memory - when incoming power is
totally disconnected or when it drops below the display unit's stated operating range of 78 to 255 volts. :h Interesting stuff though ... thanks! :B
