BlueSolar MPPT diode lights green?

I have 4pcs MPPT 100/50, but for two of them the Float diode lights green in stead of blue. What is the cause?

Hi @Double Joy Have you consulted the manual section 3.6 to be specific?

Yes, there is no notes in the manual 3.6 about green LED, only blue LED is mensioned ! It has been blue, but now it is green and I don’t know why ? It is the Float LED which is lighting green.
