MT50 only show connecting on screen can someone help me out

Are you using the supplied RJ45 cable, or a different Ethernet cable?
 
The MT50 will show connecting if it is getting power, but not successfully getting responses to its requests to the solar charge controller (SCC). That could happen for a number of reasons (in order of troubleshooting process);
  1. Bad cable (Try a different Ethernet cable)
  2. Bad connection at either SCC or MT50 (Visually inspect pins; if damaged - and skills allow - repair)
  3. Something logically wrong with SCC or MT50 (Power off and fully disconnect both devices for a few minutes then reconnect and try again)
  4. Something physically/electronically wrong with either SCC or MT50 (Probably requires replacement)
    • The MT50 is cheaper so that could be a first device to replace if optimizing for cost efficiency when troubleshooting
    • Otherwise, having a backup MT50/SCC can be handy so ordering both isn't necessarily a waste long term and will improve time-efficiency troubleshooting
