I have UPS installation with 6xBYD B-Box Pro 2,5 and 3x MultiPlus-II 48/3000.
Few times a day System shuts down for very short time (seconds - after that wakes up) and Color Control indicates that Error #1 then occurs. There is no grid loss then as well.
I have checked what could cause error 1 and didn't find it in the system:
-no low battery
-no temperature alarm
What can be the reason of situation described with words "Device is switched off because one of the other phases in the system has switched off "?
Can it be caused by defective Multi which works properly all day but 3-6 times a day turn off itself for a while?
I just installed video recorder to find monitor LEDs an each Multi.
