Off grid charging the Bolt

Fri Jun 07, 2019 10:02 pm

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

FWIW, a similar problem and solution was discovered by the Leaf community as well. I think this will be true of most EVs.

EV Fleet:
2011 Torqeedo Travel 1003 electric outboard on a 22' sailboat
2012 Leaf SV (traded for Bolt)
2015 C-Max Energi (302A package)
2017 Bolt Premier

Ground the neutral. It should be grounded at the service entry anyway, there and ONLY THERE. Attached article explains why this is important.

Option 0: Hire an electrician. Hire somebody else to burn your house down and electrocute your kids. This is the only legally permissible advice to give.

Option 1: Open the inverter and tie neutral to ground at the back of the receptacle. Depending on the outlet style, you can probably just get away with a hunk of wire and a screwdriver. I like this option best because it protects ANYTHING you plug in to the inverter.

Option 2: Find some esoteric, bespoke and overpriced plug that does the job and that may be potentially dangerous and blow up in your hand if you plug it in to a miswired household outlet. You probably won't know if it's miswired until it blows up in your hand.

Option 3: Make a mini breaker box just for your inverter, with one or two breakers in it, bond ground and neutral there, and screw the whole setup to a wall and ground it to a water pipe or a $12 grounding rod. In other words, get a short, heavy extension cord, cut it in half and put the box in the middle, bonding N and G there, male end to the inverter, female end to the car.
