    This described for me what I needed, and what Tigo's own info could not. Great!
  • @darkenergy5686
    Nicely done. I'm still learning about solar systems and this is an important area that I was not aware of. Thank you for the demonstration.
  • @TheMorenobarker
    Great description! Thanks for making this and other videos!
  • @myhificloud
    Good information, very helpful. Thank you for this.
  • @boriskeller1669
    sad, that there is no device for Optimization AND Fire Shutdown AND Monitoring. Yes, you can combine them, but who wants to clip 2 modules behind the pv modules with all the risks of defects (and of course the price when using many pv modules). So the m device can really NOT separate the module from the string by command?
  • Hi I’m about to order 6 O versions, will they work without the tap ? Or are they going to need a firmware update? Many thanks
  • @neomatrix2722
    Thank you for sharing I have a question since I'm in ground Mount therefore I don't need these however I do like the idea of being able to optimize having said that I will have a high voltage array with eight panels 480 watts each combined with a Schneider Electric 100 amp 600 volt charge controller what will you recommend for me and how many of these would I need thank you
  • @scrapyardwars
    Excellent results from TS4 here. Optimisation is giving me the edge in a shaded array. Recomended if any shading I have 20 of them.
  • @Tiersmoke92555
    Safety looks expensive. Do I need to add this type of system to remote ground and none occupied structures?
