I have been installing solar panels for 30 years and have worked with all the major brands. Schneider Conext is my worst customer service experience. I had a dead MPPT 80-600 charge controller for over a month and contacted support over 3 weeks ago. Cannot get replies from their support team. Conext products look great, are easy to install, have good documentation, and all the latest bells and whistles, but all of that is useless when expensive components die and warranty service isn't an option. Attention buyers!
