GerryAZ said:The LEAF's DC-DC converter should handle the load of the Nissan L1 charger continuously through an efficient inverter (12 amperes at 120 volts requires a little over120 amperes at 12 volts because there is some loss in the inverter and wiring). There must be a connection between neutral and ground on the output of the inverter (either resistor or solid bond) for the Nissan EVSE to function. Both of my portable generators are inverter type so I know from testing that the EVSE will not charge unless there is a connection between the neutral and ground terminals of the receptacle. It does not require an actual ground connection such as a ground rod to function, but safety could be a concern if left unattended without a suitable ground.
Where are you plugging the charger in at? Is there an outlet that I am unaware of in the Leaf?
