I have installed a system with 2 LuxEnergy inverters. The front display and touch button selections looks similar to Deye units. Any of the members that can suggest the type of WiFi dongle that will successfully integrate with the unit.
Depending on your version of your 5kW FS inverter at the bottom of the inverter are 2 connectors for data transfer communication - either a RJ45 or DB9 RS232 port and a USB (similar to a printer port). With the correct cable and software on PC, Notebook or Tablet, you can capture data from inverter
