ChargePoint Level 2 Charger Drops Offline
I charged my EQS 580 yesterday for the first time using my Chargepoint Level 2 charger. Everything appeared normal. The chargepoint app and the car both displayed the data I was expecting. After a few hours I went out to the garage and saw that the charger's blue light had extinguished and the car was no longer charging. The app said the charger was off line. I have good strong wi-fi signal in the garage so I have no clue what the problem is/was. I reset the breaker. The charger rebooted and charge proceeded normally for another few hours. Same problem again. Anyone else have an issue like this?
Thx

I have not had this problem. I did have one situation where I went out to the garage and the light was white, and the charger off line. Seems ChargePoint was down, as I could not get into their site on the internet. Later, it all resolved. I would reboot the charger using the settings menu on the app, and see how it goes. ChargePoint has an active help line I believe. Maybe they could help.

Cincy, I'm going to take a shot in the dark that you're local based on the name.
What dealership did your 580 come from? If it's us, I'll let your sales associate know and I'm sure they would be happy to help trouble shoot with you.

Thanks for this. Good to know they are so responsive. Fingers crossed for my unit. Sorry about the trouble with the charger. Wouldn't it be nice if MB dealers had these things in stock like spare parts.....

While waiting for a replacement unit or if you just want to keep the present one, just unplug it or kill the power when not in use. It serves no purpose whatsoever to keep it plugged in all of the time, just wastes electricity and it should handshake back to life with your wifi quickly when powered up again. Even a fully functioning unit does little good plugged in when not in use other than tell your Chargepoint phone app that you are not plugged in to the car. The Mercedes Me app will tell you more about what you might need to know.

I wanted to update this thread with my latest information.
I received a replacement charger from Chargepoint. I had an electrician come out. install it and check the entire circuit and the breaker panel. All was good. He left. I hooked up the car and it began to charge normally. About an hour later, it tripped my breaker. I am charging at 40 amps and I have a 50 amp breaker installed. Here is where it gets interesting. When I had the original unit installed, the electrician asked for the county to inspect it as they require. We failed the installation because the breaker was not a Ground Fault Isolation type. The electrician came out and replaced it. We passed the inspection but now the charger won't last more than an hour. The Hillsborough County Florida building code requires any outlet or electrical equipment in a garage to have a GFI breaker. I called the electrician and he believes that as the charging unit heats up and the breaker also which is passing the 40 amps, the GFI breaker believes this is a problem and opens. Anyone have a similar issue with GFI breakers? I suppose we could put in a higher capacity breaker. That's my next idea.
This is not a real problem for me as I now have an adaptor for the Tesla charger in my other garage so this is probably the long term solution.

I am not a certified electrician but have experience working with county building inspectors. They usually don’t have all the answers. In this case, I believe the ChargePoint Home Flex has a GFI built into the unit which means you don’t need a GFI breaker. I would recommend replacing the 50 amp GFI breaker with a regular (and much cheaper) 50 amp breaker and I think your issue will be solved.

I think your earlier post is correct. The circuit breaker in his panel is a GFCI breaker so combined with the GFCI built into the HomeFlex there are 2 GFCI on the same circuit which can/will cause issues. Removing the GFCI circuit breaker in his panel and replacing with standard circuit breaker should fix the issue. If the county inspector has an issue with replacing the GFCI breaker then show him ChargePoint’s specs indicating built in GFCI.

One more (hopefully) the last update. My installation with the GFCI had not been inspected yet so when the county inspector came out I was ready for him. I had the Chargepoint FAQ excerpt with me. We had a nice discussion about the problem. He agreed that the best way (and the code compliant way) to get around the code was to hardware the Chargepoint box. It's a fairly easy process as the breaker panel in about six feet from the Charger so I will have the electrician back to kill this snake once and for all.
