The inverter is 15kw-60kw output which is enough to run many miners. (This same amount of electric on a home line would cost you hundreds of dollars per month)
The generator head produces 2000 watts of 24vdc then uses the inverter to convert the 24vdc@2000 watts back into 15-60kw 115/220vac useable power.
If you have enough to spare you could run the electric motor from the inverter also which would then create a loop and run 100% free.
you insert 2kw it exits 60kw , i hope it's true but i dont think so
