Just noticed my blue LED on one of my 75/15 units seems to have stopped working. The other LED’s flash when connecting with App. The unit cycled today, and otherwise seems to be working. I turned it off through the App and back on and the blue LED did not flash like it usually does. Also pulled the fuse and checked all wiring. Will see how it’s behaving tomorrow. Normally the Blue LED flashes all night long until the unit wakes up and starts bulk charging.
At this point I’m thinking the LED burnt out. Perhaps it’s not wise to have them blinking while the units are asleep as it will shorten their lifespan. Also have seen posts by others that find the blinking annoying.
