The inverter monitors the AC Shore Power, the batteries and itself. Whenever a condition occurs that is outside
the normal operating parameters, the inverter will take the necessary steps to protect your appliances, batteries
or itself from damage.
Whenever the battery voltage reaches a low level, the inverter will initiate Low Battery Cutoff (LBCO) which
automatically shuts the inverter down, along with all connected loads, to protect the batteries from over-
discharge damage. The inverter’s LED turns OFF to indicate the fault condition.
As the inverter is charging, it constantly monitors the batteries. In the event the battery voltage approaches too
high of level, it automatically turns off the battery charger to protect the batteries from damage. The inverter’s
LED turns OFF to indicate the fault condition.
NOTE: High battery voltage may be caused by excessive voltage from the alternator, solar panels, or
other external charging sources.
During inverter and AC Shore Power operation, the inverter monitors the AC and DC circuits. In the event of
a short-circuit or overload condition, the inverter will shut down. The inverter’s LED turns OFF to indicate the
fault condition. During inverter operation, if the inverter becomes overheated, it will shut down to protect itself
from damage. The inverter’s LED turns OFF to indicate the fault condition.
For further reading and additional information on the above, please reference your inverter/charger manual
that will be found in your Owner’s Information Package.
Energy Management System
The energy management system (EMS) (Figure 7-16) distributes all the 120VAC power throughout the motor
home, whether it comes from shore power, generator, or the inverter. The
EMS monitors the incoming power, and manages the power to reduce
circuit breaker tripping. It does this by momentarily shedding power to the
loads under its control when the user turns on other more critical
appliances in the motor home. EMS restores power when the appliance is
turned off. The EMS panel displays the status of incoming power and the
controlled loads.
When coupled with an inverter, EMS reduces battery charge rate prior to
shedding any loads. Working together, an inverter assist feature is available. Normally the inverter is at rest
when shore power is available. EMS utilizes the inverter and the coach battery bank to smooth out peak load
demands. In one sense, the inverter will temporarily provide power to some of the appliances, prior to shedding
any loads.
