Added another 240v tool to the mix.
I converted my old Japanese air compressor from a 100v motor to 240v.
The full load amps on this motor is rated for 7.2amps. The shut off amps are at 5.5 so I'm thinking of replacing the current 5 inch pulley for a 6.

To get more air ?

I made another convert.
I took my nissan leafs 120v "brick" charger opened it up, broke the MOV off the circuit board, took the 20vAC control transformer hooked its wires up line to neutral/ground on the 10-30 dryer cord i installed, thus converting it to 240v power.
So instead of charging at around 1.4kw, it now charges at 2.8kw.

I'm guessing the charger gets hot with 2800 watts going threw it ? also curious how many volts & AH's the battery pack is.

A leaf packs notmal voltage is something like 380v.
This battery pack appears to have most of its 24kw intact.
My OEM EVSE is the 2011 and 2012 "brick" that was designed and over built by Panasonic appliances.
The evse doesn't really get very warm at all, it's just a fancy extension cord with built in safety switch. The cords power circuit doesn't know if it's carrying 120 or 240v power.
The conversation from 240vAC to 300 to 400vdc happens in the vehicles built in charger.

Thanks for the info on the charge system , could be using 240v will have a higher conversion efficiency percentage then 120v well that's my guess.

Im going to try and get a grip on this here and now

For Solar panels is it best to convert to ac then to dc or is it preferable to use DC to DC with PV charge stations ?

All the charging setups I am aware of use AC input power.
The j1772 input voltage is something like 100 to 130vac for low power then 220 to 250vac for the high voltage.
Chademo sends pack voltage out to the vehicle. The lowest voltage chadomo I have seen uses 240v single phase, most use 480v 3 phase.

In theory if you had unlimited budget you could get a chademo that takes DC input and steps it up, but if your voltage is say 48vdc I imagine that the conversation inefficiencys would be fairly horrific. If you tied into say a 400 to 1,000v array the conversation would be pretty good.

What are you using for grinding wheels? Usually its an issue with not having the best abrasive for the job.
