I have a Huawei SUN2000 10KTL-M1 inverter and SDongleA-05 Smart Dongle, which is attached to the router with a LAN cable.
I added a DTSU666 shield, but it is located 170 m away. A Cat6 cable comes from the DTSU to the inverter; in between, there is a switch. The internet connection is 10/10 Mbps and works. Since I cannot run another cable, how do I get the RS-485 signal to the inverter? Currently, I converted the RS-485 signal to TCP at the DTSU with the Pusr USR-DR134 converter and sent it to the inverter at 192.168.1.200:502, and this data is there if I look at it with a Modbus monitor. Do I have to do anything with this signal at the inverter or not? Does the inverter only support the Modbus signal from the RS-485 meter from the COM port? If you can't over TCP, can I use Cat6, for example, 2 pairs and send it 170 m away along the same cable to the inverter? Is that possible? It is not possible to run a new cable. Another problem is in the inverter settings: I can't find anywhere to add the DTSU meter. I use the FusionSolar app — I am the owner. The inverter is online, and I can see the production, but I can't seem to configure anything. The sticker on the side of the inverter (SSID and password: Changeme) doesn't work, although the FusionSolar app shows that the dongle and inverter are connected. I would like advice and help.
