Figure 1-27 State transition for generator start and load shedding
When critical state is reached (and no charge current is detected) the Sunny Island 4248U will
shut down for battery protection. After that a manual restart of the Sunny Island 4248U is
required. If no charge current flows the inverter will shutdown after 5 minutes. Independent
from the Generator and Load Shedding control the battery voltage monitoring stays active and
will shut down Sunny Island 4248U, if the battery voltage falls below the minimum voltage level
VbatMin.
