EVCS - Ground fault - Where to find some docs about the error

Hey Victron-Commuity,

currently I've installed a EVCS-NS as described in the Victron manual. The wallbox is connected to all three phases and I have also connected an RCD ahead of it as prescribed. After commissioning, however, I get the current status "Ground fault". Unfortunately, I have not found any documentation on the status message itself and had hoped that I could get some help here. Do you know how I can solve this?

Best regards from Germany!
Tim

Hi Tim, most of the time, when there is a ground fault reported by the EVCS, that's truth.

Can you measure the voltages between L1 and GND, L1 and N, N and GND and share them here?

Hi Lucian,

sorry for the late response. I've remeasured between all phases, restarted the Wallbox and the error disappeared. I'm a bit clueless why this error happened, but it's gone for now and the wb is running absolutely fine for around 1,5 months.

@Stefan Boldt I hope you were able to fix your problem as I can't give you any information about how mine fixed itself :D

Hi. Same problem hier. Between L1 and GND and L1 and N I have exactly the same voltage (232V) Between GND and N I have 0,14V.

I my case the error message "Ground fault" shows only for a short time. Mostly less then a minute. I only know this, because I monitor it. It gows from 0 - Disconnected to 8 - ground fault and back to 0 - Disconnected in less then a minute.

My Wallbox is connected on the grid side.

Any Ideas?

I think you have a different problem. From time to time you have a ground fault error, his unit is not functional because it detects all the time missing ground.
In your case, I think I know what the problem is, please send me an email with the VRM portal ID.

It's in the message text. Lucien has selflessly exposed himself to the world's spammers for you.

Thanks Lucian for your support. The Firmware Upgrade resolved the sporadic Ground Fault errors on my Wallbox.

Thanks Stefan! When the official version will be released, make sure you're updating it, now it's a beta.

@t3mschm2d I got a beta firmware from Victron which fixed the problem with the Ground fault issue.
