+### My RS485 Adapter does not work reliably
 
 SofarSolar inverters are picky with RS485 adapters. When trying to connect my HYD xxKTL-3PH via RS485 USB I tried a couple of options. Best working adaptor was the Waveshare USB to RS485 adaptor. However even with that one I was not able to get a 100% reliable connection.
 
 The by-far best RS485 connection is provided by the replacing the LSW-3 WiFi Stick Logger with the LSE-3 Ethernet Stick Logger. The later provides Modbus TCP out of the box via the port 8899.

 Even though also on the LSW-3 Wifi Stick Logger shows that port 8899 is open, Modbus TCP connection attempts time out. Replace our stick logger with the LSE-3 LAN Stick Logger.

 Running a port scanner like nmap on the LSE-3's IP address does not report port 8899 as being open.
 
 I have seen that it might take a while until the port 8899 gets opened by the LAN Stick Logger. Try again the next day.
 
 If that does still not help check the LAN Stick Loggers Firmware: Open the web interface at `http://\<LSE-3 IP Address\>` and on the 'Status' page expand the 'Device Information'. Check that the Firmware version is 'ME_0D_270A_1.09' or newer.

 1. Shutdown the inverter.
 2. Disassemble the COM Port connector, by unscrewing the handle from the connector. Then press the clips on the front and gently pull out the connector. Be careful not to disconnect any of the other wires.

 5. Carefully assemble the COM Port connector again.
 6. Connect the other sides of the RS485 cable to your adaptor.
 7. Turn on the inverter.
