      I'm not hacking them. But they fail to convert if the grid signal is not present. And rightly so. But I heard that you could trick them by making a 220 volt "faux" grid signal. But the problem is that the energy harvested has to go to a load equal in value. That is a challenge. Remember the physics principal that energy can not be created or destroyed. Recently SMA came out with a grid tie inverter that would supply a 1600 watt load. I'm sure the SMA unit is careful to generate exactly what the load is, and throttles back for lesser loads. 

      Thanks, Bill Swann

      In that case it’s very doable


      It sounds like a 2 phase inverter is simply a 120/240 output, and most micro inverters can be fooled by that if it’s 60Hz



      So now we’re hacking micro-inverters? 


      This group is learning fast…..:-)

      @Kevin Conlin
      When I said:
      "It should be possible to simultaneously charge the EV and tap its batteries."

      ...I was guilty of a poor sentence that sounded like bad physics.  What I mean is that it should be possible to simultaneously CONNECT the EV to both a charger and a battery tap, but only 1 of them runs at a time.  When the sun shines the EV will charge and the load on the battery tap will be very low....just enough to fool the microinverters.
