I have been working on charging my leaf with my Honda 2000 generator. But the on board charger does not think it sees a ground. The genie is grounded so I think its a sine wave issue. Any one out there find a fix for this.has anyone tried to use a portable genorator like the Honda 2000.

I have. The ESVE looks to see if the neutral and ground are tied together. The easiest way to fix this is to buy a plug and wire the ground lug to the neutral lug. Then the ESVE will charge properly.

Yes been there. The evse unit does not work like that.. it still throws no ground error.. thus the sine way question. I have lots of experience powering large events via Geni ..ie lighting rigs sound etc. We have always needed a delta wave in between the generator and the dimmers and sound electronics to allow them to function correctly. Without it they get a pilot but the sinsitive electronics in the rack will not recognize the sine way and shut down.... what type of generator have you used?

I know that Honda makes some nice sine wave generators:

It has been reported elsewhere that something like the Honda EU2000i functions properly as long as the ground and neutral are tied together for the EVSE GFCI check. Personally, I'm trying to locate a good diesel (biodiesel compatible) generator that isn't too overkill (maybe 4 KW max) to use as an emergency backup.

Yup that's the Generator, the 2000 its a very nice unit. I have owned it for about 4 years now. I used it as my backup for my Zap Truck.. I just locked it to the bed and always had emergency power :).

As for my charging with the EU2000, I have now discovered that the Ground lug was not connetd to teh Generator properly, Ill go back and try again now that i have found that.
Sounds like it should work fine now..

More info to follow....

Has any one used inverter ( 12 to 120) ? I guess it would have to be or more then 2000 watt. If it was a good sin wave it should work ya,. But 180 amp at 12 volts might be the killer ..then you use Auto Alt. and engine ..

I am sure my Xantrex Prosine 1800 would easily drive the L1 charging. Not sure if there is a neutral ground bond when inverting to get through the brick.

I need to give it a go and see what happens.

Yes, I have successfully charged using my EU2000i after providing a path for the ground verification.

I suspect the LEAF's on-board charger will also happily accept DC. Modified sine (step square wave) should not be a problem.
