4-2-3. Power Sharing Mode
If the available power at the AC-input is limited, and the load connected to the AC output load increases, the
external AC circuit breaker may trip accordingly. To avoid this, SL series can automatically reduce the battery
charger output, and thus the AC power consumption. This Power sharing feature constantly senses the
incoming AC current which is used to supply both the battery charger and the appliances connected to the AC
output load.
The Power Sharing level should be set to match the value of the external circuit breaker, which protects the
incoming AC power.
