I was under the same impression as David. At one point when I looked into it all the electrical specifications appeared identical. Lux isn’t made by Deye? Ripping off designs within China isn’t just exclusive to the US? Good ole inverter manufacturer family incest? Does the main difference only relate to AGS controls or something along those lines? Even that is within the Lux products, Envy and EG4? I’m not into either personally but was dragged into a Solark system two years ago. Doing my best to keep my back strong with transformer based inverters until I can support Midnite.
