I have had my battery on float charge for the past few weeks with no loads. During the night time, the blue LED would blink every 3 seconds to indicate that the system was powered.
I recently disconnected the charge controller to move the battery. Once I reconnected the charge controller, during day, float charge LED was on. But during night time, there was no blinking blue LED. It has remained like this for the last 5 days.
What would cause the blue LED light to stop blinking at night?
I am using 75/15 MPPT SmartSolar.
12V Battery OCV is always somewhere above 12.70.
