Thank you, Stanton, that helps.

In my case, I am not the homeowner so I can only use the options that are commonly called portable. The homeowner needs to get the wiring evaluated by an electrician. The responses here can help by defining what the requirements are.
You would get better advice if you post a few pictures of the existing 240V receptacle and the associated breaker, if you know which circuit it's on...

Just have to make sure it isn't a "welding circuit " ran on undersized wire.
Need to see plug type, breaker rating, wire size and type, then an idea as to how long the run of wire could be.

Yes, we are in the habit of saying 220V.

I'm hitting about 252 volts with the solar from about noon to 3.
My leaf doesn't seem to mind.

Yes I seem to remember the Leaf will work up to mid 250s for voltage but the common commercial voltage of 277v is too high :(

Surprised your inverter doesn't do a better job of regulating output voltage? You are not charging with DC directly from the panels? How do you get 252 V from an inverter, mostly they invert to 120V..... We have the same system here, panels batteries Outback.....

Cheapest way to go is downscale a bit if you have an available 30 amp breaker to use. 30 amp dryer outlets are common and cheap. It would take you a few hundred to run a plug from breaker panel if its located in the garage. Then $300 for a EVSE and you are set. FYI; You will charge roughly 10% SOC per hour on a Plus (62 kwh)

That's what happens when you add 30 amps to a circuit with no load.
The enphases are doing exactly what they are supposed to.
All the 120v micro inverters I have ever seen appear to be garbage.
There's no way I know of to charge a car with DC directly off the panels and if there was I wouldn't want to pay for it.

The only thing is for it to be up to code the circuit and breaker needed to be sized to run the max amps the charger can dish out.
That's why I'm good with 20 amp circuits on 12 gauge wires because my 2011 maxes out at 16 amps so I only have a 16 amp evse.
