My guess: Each unit is a DC to DC converter with a controllable 1:10 boost to the output side; module side has a MPP tracker; inverter side outputs are parralleled and adjust to a single common voltage. The string inverter sees a constant DC voltage of 200-300 depending on the module Vmp.

Ok, so I've read the pitch from the Manu, however not sure even if the published specs for shade improvement are very convincing to me.. Would one of my esteemed colleagues explain what it does and how it works. Thanks, Don Loweburg
