240 volts, derated to 40 amps due to use of 6/2 stranded copper Romex and a 50 amp breaker. Tried using 4/3 Romex with 60 amp breaker for 48 amps, but the wire was just too thick and inflexible for my application. Check out the difference in size between #6 and #4 Romex!
Thanks to this Forum, I knew that #6/2 stranded Romex is only rated for 44 amps continuous load (80% of 55 amp max load). That's why I originally wanted to use #4/3 Romex, but it was just too difficult to install. Plus, the service disconnect to my garage subpanel is only 50 amps anyway and #6 wire, so running #4/3 Romex and a 60 amp breaker wouldn't have made much sense.
During daylight, some of the charge will come from the solar array on the roof of my garage.
