Hi
I have a smart solar 100/50 that has been working great for just under 2 years.
Now it shows normal voltage on solar panel(48v) and on battery(13.3v), but no amps on a very sunny day. it will intermittently go up to 0.2a(12v) for a couple of seconds before going back to 0. I rewired to the batteries and solar panels to see if it was a cable issue. I also connected it to another battery but it reacted the same. It is acting like its going through a cycle trying to start charging but stops 2 seconds later. I also checked the temp shutoff option.
