loud as fuck  it is a dec  2017   14th model.  I am holding it on the side as a buyer has  stuck funds so I told him I will wait.


Buysolar's 3 board model may be  old firmware.

I also think he has a two board with old firmware.

I am moving some gear around on Monday  I will check out exactly what  we have in s-9's

I am personally down to the 14th 2 board. and it has a dead board which may be fixable

buysolar has

 three  board  12.3 th
 two     board    8.0 th  with old firmware.  only 2 boards
