Re: [RE-wrenches] 3-Phase Service, One Phase Fails

I have felt for some time that inverters should have a logic control to turn them off. "Short contact A to ground to disable inverter" type of interface. If we had that, we could implement generator protection very simply. For your application, I see these being used in 3 phase pump control system

Greetings Esteemed Wrenches, We are building a 35.75kW project with (6) Power One 6000's. The service is a 240 delta. The utility is requiring (late in the game) that if one leg of the service is lost, all inverters must shut down. Of course, we have two inverters that do not shut down in that c
