Started at 7:30pm last night and finished 4:30am this morning.  Drilled mounting holes on the solar panel frames and  installed the Enphase IQ 240v AC micro inverter.  A much simplified setup.   Got rid of all of the DC string wires. Now there is just one  240v AC trunk line that hooks up to the output side side of the 18kw master inverter inside the house.
