Critical state is meant to be the last limit that for example should be used to trigger a circuit breaker.
The Critical state is managed using the Critical Control Logic.
If item is in the critical state, then the icon below will show and Mode will be in the OFF state.
Items highlighted in yellow are items that are set:
Note: Extra Parameters has some possible fields that might have been breached.
Whenever a critical event occurs a snapshot report is generated automatically. This records the state of the batteries at the time they went critical.
It is then just a case of looking at the critical settings you have on your system and comparing them to what the system says was happening at the time to find which limit was breached.
