- | * When the system operates in state of charge areas where derating is necessary, typically below 20%: do not connect loads to the AC-Out of the Multi. Any power flowing from the battery to the AC-Out is not taken into account and will cause extra discharge current during discharge. And during charging the power drawn by loads connected to the AC-Out of the Multi will cause a reduced charge current. | + | |
* The derating mechanism is not very precise yet. In other words, do not expect a discharge limit of 30A to result in a precise discharge of 30A. | * The derating mechanism is not very precise yet. In other words, do not expect a discharge limit of 30A to result in a precise discharge of 30A. | ||
