real soon , just sent off the PWM Controller to be made
these cost me about $50 each that is including shipping , but that is cost when you only do 5 , will have a better idea when I have the controller made and working with these , almost finished the DC/DC design (48vdc ->> 400 vdc)
to made a inverter , you need a Driver , Controller and DC/DC . the dc/dc could be made
to run off 12 - 48v and in John II case 100vdc
