I have a 2019-vintage, GoPlug-branded, OpenEVSE that has started raising “GFCI Self Test Failed” on restart or power cycling, after raising the same error a couple of times when the EV was first connected. I have not tried turning off the self-test, or opening up the unit. It’s running v2.9.1 wifi software.
It did log one GFCI fault when first installed in July, 2019. I don’t know what the electrician did to cause that.
We did get the household service panel replaced in January.
RAPI $GV returns >$OK 1.0.0 4.0.1^24
If the unit has been installed via an RCD you can safely turn off the GFCI. Or you could try replacing the GFCI sensor:
Thanks. I ordered a replacement GFCI sensor.
And the replacement sensor fixed the problem.
Since yesterday I have the same issue. GFCI self-test suddenly started failing.
- European EVSE, kit bought mid 2021
- OpenEVSE FW 7.1.3 EU
- OpenEVSE WiFi FW 4.1.0
It worked fine until a few days ago. I tested the “no ground” detection and it still works: if there is no ground the situation is detected and OpenEVSE stops the charge. So the coil works. Could it be that the self-test circuit may be a bit tight with its test current? Or is there a real component degradation issue?
I disabled the GFCI self-test. RCD is in place.
