AC charging on one circuit is tripping GFCI breakers on other circuits in my electric panel.
I have tested charging the EP500 on three different 20 amp circuits and each time one or two GFCI breakers on different circuits trip immediately after turning on the AC charging. The GFCI breakers cannot be reset until the Bluetti unit is no longer charging (I disconnect it).
The 20 amp circuits I am using for testing have for years run a variety of kitchen appliances (microwave, induction cooktop, mixers etc.) and vacuum cleaners and have never caused GFCIs on different circuits to trip.
There seems to be a wiring fault in my unit. FYI, the AC cord being used, pin 5 is the ground, pin 4 is the hot, and pin 2 is the neutral. Pins 1 and 3 are not connected to the 3 prong plug.
I am posting this to see if anyone else is seeing a similar issue.
Adding this [edited] from the Kickstarter comment section where I responded to a question:
[The circuits I was using for charging] just happen to be 20 amp circuits since I am in the kitchen, testing the refrigerator for run time.
And yes, circuits the EP500 is plugged into [for charging] do not trip. It is one or two completely different circuits (happen to be GFCI) that are tripping.
Months ago I looked into getting a second EP500 to tie into the electric system. Ran across lots of info on how important a floating neutral would be for this. The EP500s use a bonded neutral. An online search turning up a discussion about one circuit tripping another circuit suggested the possibility of a white wire being used as a part of a switch leg that is somehow feeding back into a neutral.
Maybe the ground is involved too.
