Can you charge from a non inverter generator?

Sat Oct 06, 2018 2:46 pm

I have a 3550w champion generator and I want to slow charge at 1.5kw has anyone done this?

L-1 charging generally works fine. It's L-2 that requires modifications. Ground the generator to play it safe.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

So I just need to do the 2 100k resistors?

Need to know the model # to determine which resistors you are referring

@50% capacity 1500 W from a 3550W sounds about right , lots of threads on grounding on this forum
Just make sure it is pure sine wave not modified

The manual is pretty vague on this more specifically on page 15 where it states : see your model's control panel for specified type of grounding"
So look at the control panel and see if it shows a recommended neutral bonding procedure.
I can tell you this , you will definitely NOT want the neutral to be floating but some form of solid bonding to ground.
If the information is not indicated on the control panel you may try this as it seems to fool the EVSE

It says neutral floating

I could get a grounding rod?

Since the generator neutral is floating, you will need a single resistor (or solid bond) between neutral and ground. I use either a single resistor or a solid bond between neutral and ground, depending upon the application. I made up 120-volt plugs to keep with the generator (one with a solid copper connection between neutral and ground; the other with a 100k ohm resistor). That way I can run the generator floating (no plug), resistance grounded, or solidly grounded simply by choosing the plug to insert into one of the outlets. For safety, the generator frame should be grounded to a ground rod, regardless of operating mode. At home, you could ground the generator frame to a metal water pipe.

Rotating machines produce sine waves by their nature so conventional generators produce true sine waves. Inverter type generators have high quality inverters so they also produce true sine waves. Either type will work for charging the car as long as the generator has sufficient capacity to match the EVSE and the neutral is either solidly grounded or grounded through a resistor. Modified sine waves are only produced by cheap inverters that produce limited power from battery sources.

What is the difference between the two types ? Resistor and soild

If there is a ground fault in the circuit being supplied from the generator, the 100,000 ohm resistor will limit the leakage current to about 1.2 mA (less than the 5 mA level of most ground fault circuit interrupters) to minimize the shock hazard. Since the leakage current is below the threshold of GFCI protection, the GFCI protection (either external or built into the EVSE) will not activate.

A solid bond makes the circuit equivalent to plugging in to a non-GFCI receptacle in the house. Therefore, there is no personnel protection unless GFCI devices are used (either external or built into the EVSE). I recommend the resistor connection for most applications since it does not depend upon GFCI tripping to prevent shock hazard (that is why most portable generators are floating).
