Load Shedding - Maretron MPOWER CLMD16 User Manual

___________________________________________________________
Load shedding is a way to extend the time the system can keep working when the battery voltage is
getting low. As the battery voltage drops, the CLMD16 will turn off low priority loads. This is based
on 3 priority levels. These priority levels have configurable voltage thresholds. An example of this is
depicted in the table below. As voltage rises, for instance, as batteries are recharged, loads will be
reactivated in a reverse sequence of the order in which they were turned off. See Table 7 for an
example of Load shedding Priority based on battery voltage.
