If the inverter neutral is truly isolated from ground, you need to make a connection between neutral and ground with either a resistor (100k ohm is appropriate to limit ground fault current below the standard GFCI threshold of 5 mA) or a bonding jumper. I made up some adapters using 120-volt plugs (one with resistor and one with solid jumper) to use with isolated generators to charge the car or to run test equipment that checks for safety ground connections. By using the plug-in adapters, I can leave the generator isolated for normal use and grounded/bonded when needed by just plugging the appropriate adapter into the second receptacle on the generator.billduck wrote: ↑Mon Jun 15, 2020 3:33 pmThe Level 1 charger will not work if a 110 Vac plug is ungrounded. Makes sense. I tried to charge my Leaf with a 2500 watt solar inverter. It did not work for the same reason (No electrical connection to ground.) Since the electrical service (that works at Level 1) has the neutral and ground connnedted in the brealer box, is the answer, on the solar inverter, to electrically connect neutral and ground? FYI, the source of power for the 2500 watt inverter is a large 24 volt, Lead-acid battery bank.
Thanks in advance.
We agree on that. Just provide a grounded outlet for the EVSE.If you have to defeat a safety system to make something work, it's a bad idea.
Higher end pure sine inverters will fry if you connect ground to one of the 60v "lines" and modified sine wave appears to not work well at all with the leafs charging system or any charging electeonics.
