For information my residential system runs 350V DC into the inverter, which goes to 240V AC. This is on a small 3.8kW array. I'm not sure it helps the OP. Any real solar usage for motors that size is going to require a large array and large battery bank, how large depends on duty cycle, but could be insanely large.
240 V
AC is neither more nor less "lethal' than any other source of it. All around most of us, managed to "codes", and we Just Deal With That.
350 V
DC is one seriously nasty stick-and-fry
rectumfrying bitch.
Commercial farm the size of a County, professionally operated and maintained? Not a problem, even at higher-voltages by far. Some of our longest unrepeatered submarine telegraph cables were once keyed at 8,000 Volts DC to carry 4 WPM traffic, simplex phantom.
Residential? WTF. Extra conductor mass for heavier-current, lower voltages are short ones.
Batteries are inherently 2 V per cell or LESS, most any technology out there, Edison onward, and inverters can boost the voltage as easily as not.
But why would any money-grubber give the least of a damn about safety when they have to "make their numbers"?
Telegraph & Telephone companies, 1800's onward didn't migrate off 130 VDC - and HIGHER - to neg-48 VDC by accident.
We made that move BECAUSE of accidents. Fatal ones. And more than a few.
Whole cities and nations were once wired with overhead lines, and they began as BARE WIRE!
Not to mention that insulation FAILS now and then, too. Or lines get downed or damaged.
Piss-away 150 years of hard-learned lessons, every continent and island on the globe?
Have at it.
Surely won't be the first time.
Irony? First, most successful, and one of the most enduring of telephone switch designs, EVER, anywhere, and everywhere? "SXS" Step-by-step. Strowger.
