There are single-phase inverters. I have not been impressed by build quality, part selection, or reliability stats. That said, I have not put out the cash to buy one. My 3 phase controllers are re-built industrial models. Plus the one that I got from Paul Holmes.

Most single phase motors are set up with a capacitor start, or some other method to get starting torque. I'd have to remove the start method in order to run low frequency. And the single phase motors, that I have used, do not appear to be designed to run continuously. They overheat and trip on thermal, then need to cool down and be reset. Not a great thing if you are not home all of the time. Worse are the ones that heat up and fail the insulation, then just stop entirely.

A single phase feed into the diode bridge of a 3 phase controller charges up the bus, and I can drive 3 phase motors - that I can get cheap, and that are very robust since they are designed for continuous duty in commercial or industrial settings - with good speed control, decent bearings, etc. I can also run the motors at 250 - 300% current for short periods of time, if I mess up.

Think drill press, table saw, jointer/planer, septic pump, well water pump, domestic water pressure pump in the house.

BUT ... it is not to be. If there is a fire, the default reason seems to be electrical. So if I have 'illegal' stuff in the house - it will be blamed and I won't have any insurance. So I just do vehicle stuff so far ... and maybe play with some stuff outside, not near any trees

As I understand it, I'm not allowed to output 3 phase in a residential dwelling. It is a bit of a gray area whether I am allowed to output 3 phase on a residential property (like a shed)

I have a VFD and 3 phase motor setup for an air compressor, plus the thousand or so at work that I work with.

Sorry. I was not paying attention to who was posting. I think I already knew about the work stuff.

Didn't know about the compressor at home, though.

How does any one get by with a 120v charger?
The 240v evse brick mod is the best mod ever.
I will be very hard pressed to do a better one than that.

I had to give up thinking I could get a CHAdeMO for home when I saw the price.

I find it hard to justify getting the 240v charger for home...

I live 7.5 miles from work. The short drive was killing our cars. Then work put in a charge point at work, so... having only 120 at home is not been an issue, but I can charge at level 2 at work...

I may not be able to charge at work.
At work 120v would be fine since I work 12 to 13 hour shifts for which to recharge from 15 miles of driving would be plenty.
Since I have been welding and plasma cutting and using big air compressors for so long having 240v power in the garage, in addition to the cloths dryers power and 240 to the drive way is normal to me.

I have aquired a single phase powered 10kw CHAdeMO unit.

Will you be sharing a photo or video of your home charger?

Who made it?

That will come in handy for traveling if you keep it portable. Unlocked 1450 outlets can be found. Make up a long AC extension cord.
