I live in California and with all the electricity shut off talk , I decided put in an emergency solar system in with Lifepo4 batteries . I designed and built it myself, one of it’s jobs is to charge the Bolt with the 120 volt charger.
The reason for this post is to alert Bolt owners about a potential problem.
When I plugged the charger into my Inverter I got a ground fault error. After a lot of research I found a solution.
So here is the disclaimer, I am not an electrician so you do this at your own risk.
Most inverters and generators have a floating neutral, so the Bolt charger will see this as a ground fault and the red light stays on and it will not charge the Bolt.
The solution is a Neutral to Ground bonding plug, if you go to the noshockzone web site all will be explained.
BTW the GM Bolt manual states that you should not charge from a generator.
But it can be done, I hope this saves some folks a lot of time
