One Controller has shut down as the other controller is all thats needed to keep the batteries in float.

Ie the voltage on one mppt maybe reading very slightly higher than the other

Thanks Paul for your answer, why one controller blink every 3 sec at ''bulk'' mode even is charging similar amps to the other one that is not blinking?

Out of curiosity, are any of your MPPT's connected to the BMV as your question title suggests?
