I have a Solaredge EV inverter/charger and it has been tripping during the night when I have been charging my Bolt. The maximum draw of the charger is 7.6 kW and it has a 40 amp breaker. The installer used a older 40 amp breaker and I thought that was 100% the issue. They will send an electrician to check up the setup. The weird thing though is I have noticed that the breaker is tripping about the same charge percentage every time. This seems to be more than a coincidence at this point. Could it be possible that the onboard charger could possibly do this? Thanks for any advice.

Breakers can "wear out" over time if they're run near trip values for extended periods. It's possible your breaker is heating up to a certain temp when being used for a certain period of time and tripping. For $20 try a new 40 amp breaker. It's not a GFCI breaker is it?


BTW DD... how's that sweet Model S working out for you?

I am going to have the electrician change the breaker for a new one, but it is very strange that it is tripping exactly at the same state of charge every night. It is not a GFCI breaker.

The Model S is an amazing car and I have put on almost 27,000 miles on it for one year. Still have 3,000 for Tesla's extended warranty. For all the horror stories I have heard about Tesla service, I have experienced the opposite. They honor all warranty items, there pricing is upfront and fair, they give you free rentals during service, and drive to your work/home if they can to service your car there. The Bolt is a much better commuter car because of its size and efficiency. However, I won't take the Bolt on any trips that require fast charging because of the supercharging network. It is that good and easy to use. Plus having free supercharging for the life of the car is nice as well.

I'm jealous. I've taken 2 test drives of the Model 3, not nearly as nice as the S. I got a Model 3 for the weekend once, put 200 miles on it and loved it. I can't even manage the S.

I have the same setup (bolt & SolarEdge Evinverter) and haven't had any with breakers tripping although I did an issue with a defective disconnect and or a mistightened lug. I just installed an electric hot water heater to take advantage of the solar array and had the same problem with a tripping breaker. Replacing the breaker fixed it.

I'm assuming that you have all the charging timer turned off in the Bolt per the instructions in the SolarEdge manual? Also the 40 amp circuit is a dedicated circuit, correct? There are no other loads on it like baseboard heat? I ask because I'm curious why the installer used an older breaker. Also the Breaker needs to be installed in the spot the furthest away from where the conductors connect to the electrical bus on the service panel. When I did my install I had to move a breaker to do that.
