I was told at a training a couple years ago that there were going to be some modules coming out soon that had a microchip in the module junction box which would replace the diodes and effectively work as MLPE. I have not heard anything about that recently though. Does anyone know what I am talking about? It seems that this would solve many of the issues associated with MLPE, but still be able to have the benefits. Cheers, Dave
