Has anyone done this TRIFECTA?

Being on the grid only costs me $13 a month.  
The Powerwall 2 is only 13kwh  
My rooftop solar is 14kwh

A full Leaf pack would be 24 kWh lithium ion  
A full battery pack capacity (was increased to) 17.1 kWh for 2015 model

So for my large home I would go Leaf. ie figure $3k for the pack

But, looking at how much hassle and cost it would be to do myself. BMS plus  
power supply plus another inverter? Plus licensed electrician for final hookup?

Evidently whether going your own or Powerwall 2s, you would get tax credits.
